Abstract

Two new and an undetermined/unnamed species in the penicillate diplopod genera Lophoturus BROLEMANN, 1931 and Macroxenodes SILVESTRI, 1948 are described from the vicinity of Manaus, Central Amazonia, Brazil: L. adisi n.sp., M. amazonicus n.sp., and M. sp.. L. adisi n.sp. is characteristic in having the molar plate with a swollen dorsal molar plate shoulder of the mandible , while M. amazonicus n.sp. in having three thick bacilliform dorsal sensilla separated from a second group of posterior ventral sensilla on antennal segment VI, the gnathochilarium wìth 2l to 23 palpal sensilla and the femoral and tibial setaewithanoval basefurnishedwith3or"llongspines. Also,L.adisin.sp.,whichisthedominant species at the locality, has been investigated as to its postembryonic stadia and rnandibular structure. On the other hand, M. sp. is characteristic in having more numerous sensilla located in one or two ro'ws in the dorso-distal part ofantennal segment VI, in the tergal trichomes grouped in two separated oval areas, and in22or23 palpalsensilla. Plesioproctus CONDÉ, lg64isshowntobeajuniorsynonym of Ancistroxenus SCHUBART, 1947, n. syn. The synonymy results from a revision of type material of the Brazilian Ancistroxenus tupiensis SCHUBART, 1947. Plesioproctus comans (LOOMIS 1934), flrom Trinidad, is forrnally transferred to Anci.stoxenu.s, resulting in A. comans (LOOMIS 1934), n. comb., a species which is also a subjective senior synonym of Ancistroxenus tupiensis SCHUBART, I 947, n. syn.. A. comans has been recorded from the study region for the first time, and its posternbryonic stadia are fully redescribed. A key to the genera of the family Lophoproctidae is given.

ISHII (1988) pointed out that the mandible is a useful diagnostic character in the taxonomy of Three trichobothria arranged in a triangle; two posterior ones with cylindrical funiculi and anterior one penicillate diplopods.

The general features of the mandible in this new species are similar to those of L. okinawai. Nippleless palpi of gnathochilarium with 78 bacilliform sensilla (Figs. 2 and 3). However, the molar plate in l. adisí n.sp. has a swollen dorsal molar plate shoulder (Figs. 23 and 24) with Labrum covered with indistinct large granules on surface and armed with monolamellar teeth at a rather small number of coarse granules restricted to the invaginated portion, while l. okinawai has a flat anterior margin; medial portion deeply indented, posterior portion with a line of minute setae (Fig. l). dorsal molar plate shoulder subdivided into two lobes by a distinct suture, of which the posterior lobe is Clypeo-labrum with 6+6 setae. covered almost entirely with a large number of smaller granules (Figs. 25 and 26).

The following type designations have been made: the lectotype female in tube l; a paralectotype female in tube juveniles described from Amazonia are similar to those from Jamaica (Mona, St Andrew 2; a paralectotype female in tube 3 (among 6 adult females, pâralectotypes and I female paralectotype with Parish) (TERVER & CONDÉ, 1965); on antennal segment VI or its equivalent in l2 pairs of legs). juveniles, the two thick bacilliform sensilla - intermediate (i) and posterior (p) - are always situated behind each the other; the thin bacilliform sensillum (A) is anterior and Description. Adult females. often slightly more proximal than i (see holotype: Fig. lB, C).

Ancistroxenus tupiensis is very similar to the holotype of A. comqrls: its antennae are Head.Yertex with one pair of posterior tufts arranged in two rows: anterior row equal to or slightly long; the length to width ratio of antennal segment VI is the same (3), the external longer than distance between the tufts and consisting of l5 to l8 trichomes, posterior row with 3 to 5 structure of the labrum is the same, etc. Bacilliform sensillum p and i are evident; A is trichomes. Antennal segment VI three times longer than broad (Figs. 54 and 56); l9 bacilliform sensilla not evident, but its position seems variable in this genus and is not a reliable character on left segment VI and 25 on right segment in female No. 3 (Fig. 56); one coelo-conic sensillum on right for identification. A. tupiensis falls within the range variation of A. comans and is a segment VI of female lectotype (Fig. 54); coelo-conic sensillum absent from antennal segment VI of of synonym female No. 3, on two regenerated antennae of female No. 2, and on left regenerated antenna of female of comans. lectotype.
