ANNALES HISTORICO-NATURALES MUSEI NATIONAL1S HUNGARICI Tomus 75. Budapest, 1983 p. 107-116. On several new Glomeridae (Diplopoda) from Indochina by S. I. GoLOVATCH, Moscow Abstract — Six new lndochinese species of the millipede family Glomeridae are described: Peplomeris magna sp. n., Hyperglomeris maxima sp. n. and H. conspicua sp. n. from North Vietnam. Hyleoglomeris montana sp. n., H. albicollis sp. n. and H. cremea sp. n. from North Thailand. Keys to all the four so far known species of the genus Hyperglomeris SILV. ( = Dinoglomeris SILV., syn. n.k as well as to the nine lndochinese species of Hyleoglomeris VERH. are provided. With 25 figures. Present knowledge of the Glomeridae of Indochina is based on but a few papers (VERHOEFF 1915, 1920; SILVESTRI 1917; ATTEMS 1938, 1953), with a total of 12 species from 6 genera or subgenera recognized. Therefore the more agreeable it was for me to have been able recently to accumulate for study several fresh collectings of this group from North Vietnam and North Thailand which proved to comprise six identifiable species, all new to science. The present paper deals with their description and allocation among related forms. For the opportunity to study the loan material I am most grateful to DRS. Z. KASZAB and S. MAHUNKA of the Hungarian Natural History Museum, Budapest, and to DR. H. ENGHOFF of the Universitets Zoologisk Museum, Kobenhavn. Besides, I wish to thank particularly DRS. D. A. KRIVOLUTSKY and L. B. RYBALOV of the Institute of Evolutionary Animal Morphology and Ecology, USSR Academy of Sciences, Moscow, for donating me two nice series of glomerids from Vietnam. Peplomeris magna sp.n. (Figs 1—5) Locality : Vietnam, Prov. Ninh binh. Cue phuong, from pitfall traps in forest, 1 0*, 5-18 V 1966 (No. 385), leg. G. Topái. — Material examined: 1 specimen. — Holotype: The above specimen, deposited in the Hungarian Natural History Museum. Budapest. Diagnosis — Well distinguishable from the only hitherto known species of the genus, P. demangei (SILVESTRI, 1917) from Hanoi, Vietnam, by a different colour pattern, longer antennái joint 6, larger hyposchism of chest shield, several details of structure in male leg-pairs 17 to 19. Description — Length ca. 16 mm, width ca. 9.0 mm. Colour yellowish, with light brown spots: a bit darker, subtriangular paramedian and a somewhat paler, transverse, marble lateral one from each side of terga 3 to 10 (Fig. 1). Chest shield with a similar pattern, though the lateral marble spots extending dorsad at anterior half of the tergum to contact the paramedian pair. Collum without distinct spots, marble, a bit denser along anterior margin. Pygidium also without distinct spots, light marble. Antennái joints 3 to 7 light brown, legs whitish. — Antennae with a long and a little curved dorsad slender joint 6, apically with numerous small cones (Fig. 2). Black convex ocelli 7 + 1 from each side. Surface smooth, shining. Collum with 2 usual transverse striae. Chest shield with hyposchism reaching, but not exceeding caudal tergal margin, with 8 (left side) or 9 (right side) very fine striae of which 1st and 2nd (counting from anterior tergal margin) cross dorsum, while 2 or 3 subsequently reaching the dorsum but becoming interrupted and vague. Pygidium with a pair of small, round, paramedian, marginal projections divided by a gentle concavity. 0". Leg-pair 17 (Fig. 3) with very high outer coxal lobes, telopodite 4-jointed. Leg-pair 18 (Fig. 4) with a round syncoxite notch, telopodite 4-jointed. Pair 19 (telopods) (Fig. 5) greatly enlarged; syncoxite median lingual lamina high, trapeziform, emarginated; syncoxite lateral horns densely setose, only a little higher than lamina, slightly clavate; prefemur with a short, finger-shaped, half-hidden, inner apical process; femur with a large projecting inner lobe from posterior side; tibia with a small papillär round finger distally from caudal side; tarsus relatively small, acute, quickly tapering toward end.
