19. MICROLEPIDOPTERA FROM RENNELL AND BELLONA ISLANDS
BY
J. D. BRADLEY, F.R.E.s. DEPARTMENT OF ENTOMOLOGY, BRITISH MUSEUM (NAT. HIST.)
This paper is based upon material collected by my wife and myself during a visit to the Solomon Islands from September 1953 to January 1954. We were on Rennell Island in October and November, and Bellona Island for two days at the end of November. An account of our expedition and a list of collecting stations appeared earlier in this series (Vol. 1, pp. 43-57). While in the Solomons we also collected on Guadalcanal, Ysabel, Tulagi, the Russell Islands, and on Ontong Java Atoll, and certain of this material is referred to in the present paper when relevant to the fauna of Rennell and Bellona. There are no previous records of Microlepidoptera from Rennell and Bellona, and indeed very few altogether from the Solomon Islands. The present collection consists of about 850 specimens, and just over 660 of these have been studied and determined to species. They contain examples of sixty-seven species, of which twenty- four arc new to science, three of them belonging to new monobasic genera, and four species are represented by new subspecies. For one of the known species, Polvchrosis pedias Meyrick, a new genus is erected. The specimens not studied are mostly in imperfect condition or are inadequate. An examination of this material has, however, shown that it does not include species belonging to families not already represented. Most of the material was collected at light, this being provided by a Bialaddin pressure lantern which was generally used in conjunction with a Robinson light-trap in the manner illustrated (Vol. 1, p. 45, Fig. 1). Very few Microlepidoptera were seen by day. One of the exceptions was the brightly coloured Glyphipterygid Iridostoma ichthyopa diana seen flying actively in sunlight and evidently a day flying insect by habit. Two of the most interesting species taken were also active by day, although perhaps not strictly day fliers, and are the cave-dwelling Tineids Crvpsitlnris sladeni and Tinea godmani, which were found flying in the semi-darkness of caves. The composition of the Rennell and Bellona microlepidopterous fauna follows a pattern similar to that of the fauna of the Samoan Islands, which was studied by M eyrick (1927). The relation of this fauna to others needs to be studied through the genera, and in particular through the infraspecific status of certain of the species. This cannot be satisfactorily accomplished until more is known of the Microlepidop tera of the Solomons Group and other island groups of the Western Pacific. The twenty-eight new species and subspecies described below include eighteen species and three subspecies which are at present known only from Rennell and Bel- lona; the other six species and one subspecies have a wider distribution within the Solomons Group, but have not been found elsewhere. Of the thirty-nine identified species only two are apparently restricted to the Solomons. Seven species, including one which is represented in Rennell by a race, have previously been taken only in the Samoan Islands, where they were believed to be endemic. The discovery of these in Rennell demonstrates how incomplete is our present knowledge of the distribution of many of the species of Microlepidoptera occurring in the Pacific islands. Two species are otherwise known only from the New Hebrides; one from the New Hebrides and the Bismarck Archipelago; two from New Britain; one from the Marquesas; and two from Fiji, one of these being represented by a race in the Solomons. Twenty-four species, among them two which are represented by races in Rennell, are found in Papuan, Australian and extra-Pacific regions, and some are also widely distributed in the Pacific islands. A number of these species have almost certainly been spread by man, but the subspeciation evident in the Rennell examples of two seems to indicate long-standing isolation in their case at least. The two species referred to are Trisso- doris honorariella and Iridostoma ichthyopa. The former is associated with the screw pine (Pandanus), and the latter with the coconut (Cocos nucifera). In the following descriptions the colour terms used are mostly taken from Ridc- WAY, “Color Standards & Color Nomenclature” . The types and paratypes of the new species described are in the British Museum (Natural History). The photomicrographs of the male and female genitalia illustrated in Figs. 30-69 were taken by Mr. M. G . Sawyers of the British Museum. Other photographs are by the author as, also, are the line illustrations which were made with the aid of a projection apparatus. The magnifications used for the photographs of the wings in Figs. 1-29 have not been given as they vary considerably and only part of the insect is shown. Reference should therefore be made to the measurements of the wing ex panse for each species which are given at the beginning of the description.
ACKNOWLEDGEMENTS
We would again like to express our gratitude to all who helped make the expedition fwssible, and especially for the grants received from the Percy Sladen Memorial Fund, the Godman Fund and the British Museum (Natural History). During the study of this collection part of the Olethreutinae material was exam ined by Dr. A. D iakonoff of the Leiden Museum, to whom I am indebted for the determination of Bactra coronata Diakonoff and Polychrosis pedias Meyrick. TORTRICIDAE TORTRICINAE 1. Adoxophyes templana (Pagenstecher)

(Figs. 1, 30) S 10 mm. Labial palpus light buff, terminal segment with a small sclerotized protu berance above at apex (probably normally hidden by scales). Head light buff strongly clouded with mouse gray. Antenna grayish light buff, scape light buff. Thorax and tegula fuscous. Fore wing badly rubbed in the type and markings partly obliterated; general coloration grayish fuscous, costa marked with rather indistinct white stri- gulae, an admixture of fuscous in discal area; cilia missing. Hind wing and cilia fuscous. Legs light buff suffused with fuscous, hind tarsus with fuscous-black annuli. Male genitalia: Fig. 30. The shape of the valva is similar to that of the Papuan species tenuitexla Diakonoff, to which diffusa is evidently most nearly related. There are considerable differences in the number and arrangement of the setae and margi nal teeth on the valvae of the two species. In diffusa there is a dense cluster of about 8 or 9 heavy setae present in the inner ventro-lateral margin of the neck of thecuculliis which are absent in tenuitexta ; and in tenuitexla only three marginal teeth are present on the cucullus, while in diffusa there is a single row of teeth in the distal margin evenly spaced and extending from near the apex to the inner angle, and a second more compact row grouped irregularly in a more or less straight line from the inner angle directed obliquely inward and extending nearly to the neck of the cucullus.

This species is tentatively assigned to the composite genus Spilonota Stephens, and for the present Is placed near ocellana F., the type species of the genus, which it most closely resembles superficially. It qualifies for Spilonota according to the existing clas sification based upon wing venation, but the structure of the male genitalia, the shape of the fore wing and the indentation below the apex as well as general facies and coloration indicate strong affinities with the new genus described below. There appears to be no appreciable difference in coloration and wing markings between the specimens of indentata from Rennell I. and those from Guadalcanal and Ysabel Islands. Icelitfl gen. n. (Figs. 70, 71) Labial palpus upturned, terminal segment very short, porrect; second segment with densely projecting scales below at apex. Head scales loosely appressed. Tongue short. Ocellus immediately posterior of antenna and adjacent to compound eye. Fore wing with rounded apex, a pronounced indentation in termen below apex, 12 veins from cell, 3, 4, 5 and 6 arising separately and converging at termen, 7 to termen, a strong parting vein in cell from subcostal between veins 10 and 11 to vein 6. Hind wing with veins 3 and 4 stalked neariy to margin, 5 approximate, 6 and 7 stalked to middle, 6 to termen. Male genitalia: Valva constricted at middle; sacculus produced distally; uncus bifid; socii well developed, semimembranous, pendulous. Female genitalia: Ostium caudad, sterigma (ostial plate) well developed, small. Bursa copulatrix subsphericat, bearing two very large, hollow, signa. Type species: Icelita tatarana sp. n. This genus is related to Spilonota Stephens and Acroclita Lederer. Veins 6 and 7 of the hind wing are stalked in Icelita, while in Spilonota and Acroclita they are ap proximate at base; Icelita further differs from Acroclita by having veins 7 and 8 of the fore wing stalked. In Icelita the male genitalia have the sacculus very strongly developed as a free process distally, a characteristic not typical of either Spilonota or Acroclita, although in the preceding new species described above and tentatively placed in the genus Spilonota the sacculus is produced distally as in Icelita tatarana. 5.

Head loosely scaled, scales projecting between the antennae. Tongue very short. Antenna simple in female, shaft scaled, minutely ciliated in male. Fore wing with all veins present, 3 and 4 connate, 7 to termen, 9 from upper angle of cell, a weak part ing vein in cell from little before vain 10 to between veins 7 and 8. Hind wing with veins 3 and 4 connate, 5 approximate, cell open between veins 5 and 6, 6 and 7 con nate or short stalked.

Bursa copulatrix elongate, entirely membranous and without signum. Type species: Polychrosis pedias Meyrick. This genus is erected to accommodate Polychrosis pedias Meyrick, study of ex amples from Renneil I. having shown that this species does not properly belong in the genus Polychrosis Ragonot. The new genus in which pedias is now placed is related to the large compound genus Laspeyresia Hubner, from which it may for the present perhaps be best separated by differences in the structure of the male genitalia, in particular by the great width of the basal section of the valva in relation to the cucul- lus in Eleuthodema, the reverse to the comparable development of these structures in typical Laspeyresia species; and by the well developed sacculus in Eleuthodema in contrast to the poor development of this structure in Laspeyresia.

COSMOPTERYGIDAE 27. Cosmopteryx aarella sp. n. (Figs. 10, 78) S ? 8-9 mm. Labial palpus white, with black lateral longitudinal lines. Front of head grayish with a weak golden sheen, crown fuscous-black with fine central and lateral white lines. Thorax and tegula fuscous-black, a fine longitudinal white line at middle of thorax parallel with a fine white line along inner edge of tegula. Antenna fuscous- black, whitish dotted anteriorly, with two narrow white bands at about 2/3 and an- other much broader white band before apex. Fore wing fuscous, a short, fine, white subcostal line at about 1/6, two slightly longer white lines beneath apex of this, widely remote from base and fascia; a broad postmedial deep chrome fascia, anterior margin straight, sprinkled with a few black scales, edged by a narrow iridescent pale golden metallic fascia; a circular iridescent pale golden metallic patch, edged by a sprinkling of black scales, on the inner margin (dorsum) and occupying nearly a quarter of the postmedial fascia and nearest the outer margin of the fascia which is oblique from costa to tornus; in the outer angle made by the costa and the fascia is a small golden metallic spot, on the costa immediately beyond this is a heavy white dash which extends into the cilia; a fine white line from tornus along lermen to apex; cilia grayish becoming blackish around apex, a white dash on costa, and a white bar at apex form ing a continuation of the white line from tornus to apex. Hind wing and cilia fuscous- black, cilia slightly grayish. Male genitalia; Fig. 78. Costal part of valva with outer side of the club-shaped ter minal portion clothed exteriorly with minute bristles; distal margin of ventral portion of valva straight, abruptly rounded at ends.

This species belongs to a large homogeneous group, but is distinguished by the broad postmedial fascia of the fore wing enclosing the metallic marking on the hind margin. The male genitalia indicate relationship with the tropicopolitan species Jiavi- fasdata Wollaston (= mimetis Mayrick), the costal and basal parts of the valva being similar in the two species; but the form of the gnathus is different, being pip-shaped in flavifasciata with the end sharply pointed; the form of the aedoeagus also differs, and in flavifasciata is cylindrical and comparatively slender throughout its length. 28.

Stagmatophora quadrifasciata Walsingham, 1907, Fauna Hawaiiensis, 1; 516, pi. 15, fig. 22. The Rennell race is distinguished by the very much wider transverse pale brownish ochreous bands of the fore wings, and a consequent reduction of white areas between the bands, resulting in the general appearance and coloration being appreciably darker than in the nominate form from Pitcairn J. This variation seems to be peculiar to Rennell, and examples of honorariella from Fiji, Samoa, Hawaiian Is., New Hebrides, Buru and Dinner 1. (the latter being the type locality for quadrifasciata) which have been examined closely resemble the type from Pitcairn. Male genitalia: Fig. 80. Female genitalia: Figs. 81,82.

Paratyp)es: same data as type, 3 ex.; Hutuna, xi., 2 ex.; at light. This species superficially resembles the Australian species triplanta Meyrick but differs considerably in the structure of the male genitalia; in triplanta the valva is al most twice as wide and the lateral process partly ^vering the exterior of the valva and articulated with the tegumen is divided near the base into two long prongs the lower of which extends beyond the apex of the valva and the upper a little way beyond the middle. It also resembles the Australian and Papuan sp>ecies tetraplanetis Meyrick ( = tyrotoma Meyrick, Syn. nov.) which is distinguished by the additional pretornal dot on the fore wing and is a slightly larger species; in the male of tetraplanetis the lateral process from the tegumen is in the form of a single prong curved inwards over the valva. 35.

This species is distinguished from the preceding by the black apical spot on the hind tibia which is absent in amianta Meyrick. It closely resembles antinoma Meyrick, found in the Kermadec Is., Samoa, Ceylon, India and Australia, but not represented among the present collection from Rennell, which has a black apical spot on the hind tibia. These two species are best separated by the male genitalia: in antinoma the saccus is not free apically, the vinculum is evenly rounded and does not extend so far ventrad, and the aedoeagus has a weakly sclerotized rod-like projection at the tip. GLYPHIPTERYGIDAE 43. Iridostoma ichthyopa diana subsp. n. (Figs. 18, 60-64) Iridostoma ichthyopa Meyrick, 1909, J. Bombay nat. Hist. Soc., J9: 425. Differs from the nominate Ceylon form in having the fulvous-yellow fascia along the termen of the fore wing slightly broader and enclosing much heavier black dots, the uppermost dot being no longer than the others, not longer and triangular as in ichthyopa ichthyopa, and the second, third and fourth dots from the apex are blue- centred. There are minor differences in the female genitalia, in ichthyopa diana the ostium is stronger and the signa are a little larger and more heavily sclerotized. The male of the nominate race is unknown, but the genitalia of a male specimen from Java, which I believe may represent yet another subspecies, have a weaker uncus lacking the lateral rows of setae on the underside, and the ventral pad of spines on the valva, which is strongly developed in ichthyopa diana, is very weak in the Javanese specimen; the anellus also differs, the lobes being longer and pointed at the apices.

Anticrates diffiua rennellensis subsp. n. (Figs. 19, 65-69) Anticrates diffiua Meyrick, 1927, Insects of Samoa, 3, Lepidoptera, fasc. 2, p. 106. The general coloration in the Rennell race is considerably brighter than that in the nominate race from Samoa. The markings of the fore wing are a uniform deep coral red in contrast to the light purplish markings, suffused crimson on the edges, in diffiua dijfiua. There is no apparent difference in the male genitalia of the two races. Male genitalia: Figs. 65, 66. Female genitalia: Figs. 67-69. Type ;^: Rennell I., Tingoa, 9-11. xi. 1953, at light.

Very near to the Australian species arthrota Meyrick but smaller, and further distinguished by the position of the strigula on the costa which, in arthrota is nearer to the apex than to the middle of the wing. 55. Ereunetis leucophaeta sp. n. (Figs. 25, 104, 105) ^ 7 mm. Labial palpus cartridge buff, overlaid with fuscous exteriorly; second seg ment with long fuscous bristles laterally. Crown of head smoke gray, cartridge buff between antennae, upper part of face narrowly banded with ochraceous-buff, re mainder of face cream-buff. Antenna grayish fuscous posteriorly, cartridge buff an teriorly; scape cartridge buff above, fuscous below. Thorax and tegula drab-gray. Fore wing with apex slightly upturned; cartridge buff suffused with drab gray, some times tinged with ochraceous-buff, markings fuscous; an elongate fuscous patch at base of costa, an inwardly oblique narrow fascia from middle of costa interrupted at middle and becoming diffuse and disappearing before reaching inner margin, a very oblique thin silvery line from costa at about 3/4 edged with dark fuscous streaks, a heavy dark fuscous streak from near end of silvery line to middle of wing, area below (tornal area) flecked with fuscous, apex pale violet-plumbeous edged inwardly with fuscous; cilia grayish. Hind wing and cilia grayish cartridge buff. Male genitalia: Figs. 104, 105. Valva broadly rounded distally, costal projection short, thumb-like, slightly tapered apically and heavily setose on the inner side. Saccus very narrow and long. Aedoeagus long, slender, cylindrical and curved. Typcc^: Rennell L, Hutuna, 20-22. xi. 1953. Genitalia slide B. M. 3661. Paratypes: Hutuna, x. and xi., 3 ex. The structure of the male genitalia in this species indicates a close affinity with the Australian iulopiera Meyrick, the type species of the genus; in iuloptera the apex of the valva is not evenly rounded but is produced to a very short tooth-like point dorsally. Superficial differences between the two species are greater, the general col oration of the fore wing in iuloptera being cartridge buff with ochraceous-buff mark ings. 56. Ereunetis intertexta sp. n. (Figs. 26, 102, 103) cJ $ 8-9 mm. Labial palpus cartridge buff, weakly infuscate exteriorly. Crown of head light quaker drab mixed with honey yellow and cartridge buff, face cartridge buff, an admixture of honey yellow hairs on lower half. Thorax and tegula grayish fuscous, tip of tegula cartridge buff. Antenna and scape grayish fuscous. Fore wing with rounded apex, not curled; ground colour cartridge buff; base dark quaker drab; dark quaker drab fasciae at 1/4 and middle, the first narrow and with margins poorly defined and zig-zagging; the second broad, divided at costa, margins zig-zagging, distal margin sprinkled with honey yellow scales, diffuse towards dorsum; a circular patch of cartridge buff ground colour in fascia above tornus; medially a mixture of light quaker drab and honey yellow scales traversing the fasciae; a thin line of black scales in fold, a curved black line from costa at 4/5 sparsely edged with honey yellow scales anteriorly and interrupted at the middle by an extension of the light quaker drab which occupies the area between this and the outer fascia except for costa, a small black apical dot edged inwardly with pale quaker drab and honey yellow; cilia cartridge buff suffused with smoke gray. Hind wing and cilia grayish cartridge buff. Legs cartridge buff weakly infuscate exteriorly. Abdomen grayish fuscous. Male genitalia; Figs. 102, 103. Valva with costa fused basally, projecting a little before middle as a short cylindrical arm with the end rounded and spinose on inner side. Saccus long and very slender. Aedoeagus moderate, cylindrical and straight. Type o': Rennell 1., Tingoa, 9-11. xi. 1953. Paratypes: same data as type, 11 ex.; Hutuna, xi., I ex.; Te-Uhungango, x., 8 ex.; Matahenua, xi., 18 ex. Genitalia slide B.M. 3631. The structure of the male genitalia indicates a close relationship with the preced ing species, the differences being mostly comparative and most pronounced in the shape of the valva which is more evenly rounded distally in leucophaeta, in the costal process which in leucophaeta is tapered apically and more heavily setose, and in the straight and slightly stouter aedoeagus of intertexta. Superficially the two species are quite distinct and are unlikely to be confused. 57. Decadarchis simulans (Butler) Tinea simulans Butler, 1882, Trans, enl. Soc. Lend., 1882 : 43. Hutuna, xi., at light, 3 ex. Distribution: Occurs throughout the Pacific islands from Hawaii to the Solomons, and has also been recorded from Queensland and East Africa.

Near the Samoan species sciophracta Meyrick, superficially similar but distinguish able by the greater wing expanse* and by the subterminal irrorate cartridge buff line in the fore wing. 63. Tinea nesocharis Meyrick Tinea nesocharis Meyrick, 1928, Exotic Microlepidoptera, 3: A ll. This species was taken on both Rennell and Bellona Islands. It came frequently to light on the coast and inland at localities on Rennell 1. throughout October and November; more than 60 ex. taken. On Bellona 1. 1 ex. was taken at Matahenua, 29. xi., at light. Distribution; New Britain to Solomon Is., including New Ireland; New Hanover, St. Matthias I. and Squally I. 64. Tinea godmani sp. n. (Figs. 29, 109, 110. 113) ^ ? 8-10 mm. Labial palpus fuscous. Head ochraceous-bufT, an admixture of ocbra- cebus tawny on forehead and face. Antenna smooth at base, apical 2/3 roughened, grayish cream-buff, basal third with indistinct fuscous bands. Thorax and tegula fuscous, with a weak pale golden sheen.

Ductus bursae elongate, a pair of weakly sclerotized disc-like signa situated on opposite sides at middle, each with edges poorly defined and with a small tooth like projection near the margin; a second pair of similar but slightly smaller signa towards end of bursa situated close together at one side. Type^: Rennell I., Te-Kangilakulaku Cave, 3. xi. 1953. Genitalia slide B.M. 3652. Paratypes: tyf>e locality, 51 ex. This is evidently a true cave-dwelling species, the larva feeding on bat guano, living in a rather flattened silken case with a granular surface. It is very closely allied to palaechrysis Meyrick occurring in the Batu caves in Malaya, and resembles it very closely superficially. There are good structural differences in the genitalia of the two species, the valva of godmani being proportionately broader distally and having the saccus very long, while in palaechrysis the saccus is very short. The female genitalia of palaechrysis lack signa in the ductus bursae, and the medial cleft in the ostial plate is very shallow. 65.
