STEHLÍK J. L. & JINDRA Z. 2003: Largidae and Pyrrhocoridae of Thailand (Heteroptera). Acta Musei Moraviae, Scientiae biologicae (Brno) 88: 5–19. – This paper adds 29 species of the superfamily to the fauna of Thailand (9 species previously known), including three new species of Pyrrhocoridae: Ectatops major sp.nov., Indra dentipes sp.nov., and Pyrrhopeplus immaculatus sp.nov. The species Dindymus rutilans Walker, 1873 syn.nov. of Pyrrhocoridae is synonymized with Dindymus semirufus Stål, 1863. Key words. Pyrrhocoroidea, , Heteroptera, new species, Thailand, distribution

Introduction Information on Oriental Pyrrhocoroidea is limited. The only comprehensive work on the Indian subcontinent is that by DISTANT (1903a) on the territory of former India, Ceylon and Burma. Unfortunately, this work includes only limited data on distribution. Some further data are also given in four DISTANT'S papers: (1879a: 12 species from Northeastern India), (1879b: 6 species from Tenasserim, Burma), (1919: 15 species from "Indochine"), and (1903b: 11 species from Malaysia). More data from the Oriental Region can be found in FREEMAN (1947) but the work deals only with the Dysdercus Guérin Meneville, 1831. All other geographic information is scattered, being a part of species descriptions. Previous to this publication, the Largidae and Pyrrhocoridae of Thailand lacked adequate study. This fauna in neighbouring Laos is also the subject of a recent contribution to the literature (STEHLÍK in press). A previously unidentified species of Macrocheraia Guérin, 1834 (Largidae) has been reported from Thailand by SCHAEFER & AHMAD (1999). It is probably the single species M. grandis grandis (Gray, 1832) within the genus. Eight species of Pyrrhocoridae have been reported from Thailand to date: Dindymus sanguineus (Fabricius, 1794) (by LETHIERRY & SEVERIN 1894), Dindymus semirufus Stål, 1863 [reported by WALKER (1873) as D. rutilans Walker, 1873], Dysdercus cingulatus (Fabricius, 1775) (by FREEMAN 1947), Dysdercus poecilus (Herrich-Schaeffer, 1843) (by FREEMAN 1947), Ectatops indignus (Walker, 1873) [by WALKER (1873) also as E. imitator (Walker, 1873) and by DISTANT (1903a) as E. ophthalmicus var. rubiaceus Amyot et Serville, 1843], Euscopus indecorus (Walker, 1873) (by WALKER 1873), Melamphaus faber (Fabricius, 1787) (by STÅL 1868), and Probergrothius nigricornis (Stål, 1861) (by STÅL 1863).

In the present study, 7 species of Largidae and 21 species of Pyrrhocoridae, including three new species in the latter family, are added to the pyrrhocoroid fauna of Thailand (altogether 38 species known).

Materials and methods Genera and species are listed in alphabetical order within the particular families. Distribution is given for each species, based on published data. More detailed data on the distribution of some species in China are included in a catalogue by KERZHNER (2001). For information on original binomina and synonyms of species mentioned, the reader is reffered to the worldwide catalogue by HUSSEY (1929). In the present work, distribution is given as supplementary information without listing the sources. Names of species are given in their latest combination.

Euscopus major sp.nov. (Fig. 1) Material examined. Holotype female: Chiang Mai prov.: Ban Fakia village, 19°19’N, 98°50’E, 1,400 m, 1.–15.V.1996, Vít Kubáò leg. Paratype (female): same data. Holotype and paratype deposited in Moravian Museum, Brno. Description. (Based on the holotype.) Clypeus, bucculae, antenniferous tubercle, and the base of the first antennal segment are vivid red. Pronotal collar, lateral margins, base of pronotal lobe (medially exceeding one third of its length), apex of scutellum, corium (excepting spots), claval commissure and apical part of the clavus, the legs, dorsal outer

12 Acta Mus. Moraviae, Sci. Biol. (Brno), 88, 2003 Largidae and Pyrrhocoridae of Thailand laterotergite, and a narrow band along the edge of the ventral laterotergite also vivid red. Pronotum base and corium (except the costal margin) lighter red or orange. Callar lobe and ventrites both medially weakly reddish. Pronotal lobe (excepting hind margin), clavus and corium with evenly-spaced black punctures. Thin, silvery pubescence on the head, the callar lobe (particularly on the margins) and on the base of the scutellum. Ventral side, with very dense pubescence, thus appears silver. Only the trichobothrial area distinctly velvet black. Valvifer 1 with fair hairs. Head, antennae (excepting last segment), pronotum (excepting margins), scutellum, clavus (excepting its apical part), large rounded spot medially on the corium and a smaller spot on its apex (adjacent to the distal margin), membrane and ventral side all black. Last antennal segment yellowish white in two thirds of its length, a very narrow band on its base and the last third black. Margin of membrane grey (wider band on the apex). Body large and wide. Eyes rather small, almost without eye sockets. Antennae thick, their first segment 1.08–1.12× longer than the pronotum. Pronotum distinctly widening towards its base, Fig. 2. Euscopus rufipes Stål: female. lateral margins rather narrow, sinuate at the level of the median furrow. Pronotal lobe convex, hind margin more distinctly rounded. Scutellum pronouncedly convex in its central part. Ventrite 7 in lateral view extended in its lower part, its hind margins somewhat agape providing ample space for the outer female genitalia (width 1.51 mm, height 1.21 mm). Female genitalia. Outer female genitalia deeply sunk into the seventh segment, thus creating an empty space particularly in the lower two thirds. Both sides of valvifer 1 running in parallel on the base, in the second half diverging diagonally; valvifer 2 closely attached to valvifer 1. Laterotergite 9 pronouncedly extended in frontal direction and in lateral view overlapping the hind margin of segment 7. Measurements (mm). Females (holotype given first, paratype in parentheses). Head width (including eyes) 1.94 (1.94), interocular width 1.13 (1.10); antenna: joint I 2.48 (2.51), II 1.46 (1.51), III 1.03 (1.03), IV 1.30 (1.43); pronotum length 2.21 (2.32), width 3.73 (3.75); scutellum length 1.62 (1.70), width 2.11 (2.16); corium length 5.72 (5.78), width 2.13 (2.21); body length: 11.39 (10.85). Differential diagnosis. The species is similar to E. rufipes Stål, 1870 (Fig. 2) but much bigger (see measurements of this species for comparison). In E. rufipes the eyes are more

Acta Mus. Moraviae, Sci. Biol. (Brno), 88, 2003 13 J. L. STEHLÍK & Z. JINDRA convex and have a distinct eye socket. From similar species that also have a red corium with a black spot in the middle (E. vittiventris Walker, 1872, E. chinensis Blöte, 1932, E. parvimaculatus Stehlík, in press 2003) it also differs by its bigger size and particularly from all these species by the form of ventrite 7 in females (prolongation of its lower part, large opening, in width as well as height, for the female genitalia, which are sunk deeply into this ventrite; for example in E. rufipes this opening is only 0.22 mm wide and 0.13 mm high). From E. parvimaculatus it also differs by its entirely black antennae.

Apices of tibiae and tarsi brownish. Velvet black trichobothrial area on the abdomen. (Holotype dorsally see Fig. 3.) Body rather small. Eyes very slightly telescopic. First segment of the antenna very long and – particularly towards the apex – thick, bowed outwards, 1.8× longer than the second segment, which is conspicuously thinner, straight and evenly widening towards its apex. The third segment is shorter and thicker than the second, the fourth is cylindrical (about one-third thicker than the first one on the apex). Head substantially shorter than the first antennal segment. Clypeus in lateral view apically depressed. Labium reaches between the mesocoxae; its first segment does not exceed the eye’s base in lateral view. With very fine, light pubescence. Head with very dense and deeper but smaller punctures (the punctures on the clypeus and paraclypei are not rounded but transverse). Pronotal collum, pronotal lobe,

Brachypterous hemielytrae substantially shortened (clavus, corium and its costal margin not Fig. 3. Indra dentipes sp.nov.: set apart), cut off almost holotype male. horizontally, only the outer margin of the corium rounded, very slightly, also inner margin, so that the scent gland opening between tergite 3 and 4 is visible. Fore-femora (Fig. 4) with two large, straight and pointed denticles ventrally and an inconspicuous denticle on the femur apex. Pleurae convex, most conspicuously pleura 3. Genital capsule. Ventral wall medially with broad but shallow depression. Ventral rim medially protruding with a triangular indentation on the apex. From this protruding part, which is slightly offset towards the inside of the genital capsule, a distinct fan of white hairs, sticking together on their bases, rays towards the sides. The ventral rim infolding drops vertically, which is why the lateral rim infolding (having a feeble rounded depression) is set back in relation to it. Dorsal rim sharp, bowing over the anal tube. The latter is broad, situated horizontally. Bases of parameres situated beside the anal tube, the parameres sigmoid, apical part almost as wide (pale with dark margins) and nestled against the ventral rim infolding. The parameres’ apices slightly exceed the medially protruding ventral rim. Measurements (mm). Male (holotype given first, paratype in parentheses). Head width (including eyes) 1.45 (1.43–1.48), interocular width 0.96 (0.94–0.98), length 0.90 (0.84–0.97); antenna: joint I 1.47 (1.43–1.51), II 0.82, III 0.52 (0.49–0.54), IV 0.78 (0.76–0.81); pronotum length 1.17 (1.13–1.19), width 2.07 (2.02–2.13); scutellum length 0.97 (0.92–1.08), width 1.19 (1.13-1.30); corium length 1.29 (1.24–1.35), width 1.37 (1.35–1.40); body length 6.21 (6.10–6.43). Differential diagnosis. The genus Indra Kirkaldy et Edwards, 1902 has been considered monotypic to date. According to the diagnosis given in the original description, I. philarete Kirkaldy et Edwards, 1902 from Java differs from the new species by its bigger size (length 7.37 mm, width 4 mm). In I. philarete the legs have no denticles while the

Acta Mus. Moraviae, Sci. Biol. (Brno), 88, 2003 15 J. L. STEHLÍK & Z. JINDRA

forelegs of the new species have two thick, sharp denticles in the distal part. Yellow coloration is limited in the new species to the corium margin (in I. philarete there is also narrow pale yellow coloration on the pronotal margins and on the connexivum).

Holotype deposited in the Department of Plant Protection, Czech University of Agriculture, Prague. Description. Body light red, antennae (except the base of the first article), tibiae (except base), tarsi, membrane, pleural margins and interventral sulci black. Corium medially without black spot. (Holotype dorsally see Fig. 5.) The boundaries of the callar lobe are proximally and distally marked by large, dense, black punctures; these punctures are less dense laterally. Pronounced black puncturation present on pronotal lobe, Fig. 6. Pyrrhopeplus immaculatus sp.nov.: genital scutellum (less dense), clavus and corium. capsule in dorsal view. Puncturation present on the pronotal collum but less distinct and in some areas without coloration. Ventrally, black puncturation is present on the base of the head, the prosternal collar, the posterior pleural flanges 1, 2, 3, and the epicoxal lobes, which partially bear colourless puncturation. An interesting puncturation phenomenon was found on the lateral margin of the pronotum and the costal margin of the corium. Looking from a certain angle, the punctures are colourless, because of their depth, to such an extent that the chitin wihtin becomes glass-like and translucent. A similar but very sparse puncturation visible on the genital capsule when looking at the ventral rim infold from the inner side. Head furrowed dorsally, frons almost flat, not depressed anterior to the eyes, eye socket indistinct, medial longitudinal furrow little pronounced, short. Antennal segments thick. Pronotum not very wide, lateral margins running a little apart towards its base, distinctly sinuate the middle. Pronotal lobe flat, scutellum only slightly convex. Margins of the corium evenly convex, more in the distal part then in the anterior. Membrane smaller and somewhat narrow on the apex. Genital capsule (Fig. 6). Ventral rim bowed upwards, on the apex medially with a small bow-shaped excision. Margins of this excision rounded, reinforced. Lateral rims sharp, with small black spines, which also occur clustered on the dorsal rim infolding beside the anal tube, itself directed diagonally upwards. The ventral rim infolding and the lateral rim infolding fall steeply towards the atrium genitale. Ventral wall divided medially into two parts: lower one laterally protruding with a small furrow (probably the remains of a stigma). Paramere red, distal part black, divided into two parts, protruding into a sharp point on the inner side, on the outer side into a wider but shorter protrusion

Both parts are inclined into the genital capsule. Measurements (mm). Male (holotype given first, paratype in parentheses). Head width (including eyes) 1.84 (1.84), interocular width 1.19 (1.19); antenna: joint I 1.57 (1.57), II 1.40 (1.43), III 1.03 (0.86), IV 1.60 (1.57); pronotum length 2.02 (2.00), width 3.40 (3.27); scutellum length 1.24 (1.21), width 1.62 (1.62); corium length 4.43 (4.37), width 2.02 (2.02); body length: 9.83 (9.50). Differential diagnosis. The species is closely related to P. impictus Hsiao, 1964 [omitted in the monography of the genus by SCHAEFER & NGUYÊN (1995)]. The latter is also red, without a medial black spot on the corium but its membrane is not black but grey with a small, round, black spot on the base. The prosternal collar and all three posterior pleural flanges are not red but yellowish-white. P. impictus is bigger and wider (particularly the pronotum base), the lateral margin of the pronotum is hardly concave in the middle, the antennae are thinner, puncturation on pronotal lobe, clavus and corium is distinctly smaller, denser and almost colourless. Ventral rim of the genital capsule distinctly bowed upwards, getting narrower gradually and bilobate at the top as in P. immaculatus sp.nov. but bigger [in the species P. carduelis (Stål, 1863) and P. posthumus Horvath, 1892 the genital capsule rims are straight and the ventral rim is in the same plane as the lateral rim]. In P. impictus the outer part of the paramere is rounded dorsally and hollowed ventrally (short, spoon-like shape).
