S. Mahunka szerk.: Folia Entomologica Hungarica 50. (Budapest, 1989)

Lateral and ventral region: Pedotecta 1 rounded, pedotecta 2-3 conspicuously large. Circumpedal carina weak and short, not reaching to the lateral margin of ventral plate. On the epimeral surface some large spots observable ÍFig. 13*. only four pairs (la, 3a, 3b, 4a) of epimeral setae present, setae 3b very long, much lorger than the others. All setae in anogenital region short or minute. Three pairs of setae arising on the anterior margin of the genital plates. Postanal area porosa elliptical (Fig. 12*. Legs: All legs tri- and heterodactylous. The form and chaetotaxy of legs have the normal galumnoid features. Setal formulas: I: (Fig. 16*: 0-4-3 + 1-4+2-20+2-3 IV: (Fig. 11*: 1-2-2-3+1-12-3 Solenidial group of the leg 1 as shown in Fig. 15. Material examined: Holotype '1357-HO-89)

: No. 341-1. Vietnam, Da Lat, 20. X. 1988. Berlese samples: litter, leg. Mahunka, S. - 10 paratypes: from the same sample. Holotype and 8 paratypus (1357-PO-89) deposited in the HNHM, 1 paratype in the CNC and 1 paratype in the MHNG. Remarks: The new species is well characterised by the long interlamellar setae, by the medially interrupted dorsosejugal suture, by the form of sensillus and by the triangular areae porosae Aa. On this basis it belongs to the relationships of vir

giniensis Jacot, 1929, G. triquetra Aoki, 1965. The new species is distinguished from them by the distance of areae porosae A3 and A4 and the form of the setae h. , I dedicate the new species to Dr. Nguyen Vang Khoi, director of the Zoological Institute of NCR (Dalat, Vietnam) for his hospitality and help during our collecting trip in Vietnam. Pergalumna kotschyi sp. n. Sexual differentiation on the notogaster present. Measurement. - Length: 451-490 p.m. width: 300-334 p;m. Aspis: Rostrum wide. Prodorsal surface with fine punctulation. Lamellar and sublamellar lines very strong, run nearly parallel to each other (Fig. 21). Tutorium and also the horizontal chitinous lath long and strong. Prodorsal setae varying in length, ro and le ciliated, in smooth and much shorter than in. Sensillus setiform, directed backwards, densely ciliated. Dorsosejugal areae porosae completely reduced. Notogaster: Its surface also punctulated but in deeper layer some darker spots observable. Dorsosejugal suture reduced, only a short part exist laterally reaching to the dorsophragmatic apophypes. Pteromorphae with a radiate design, mirror-spot . long, narrow (Fig. 17). Ten pairs of setal alveoli, three pairs of nearly equal large, round areae porosae present. Median pori observable in males, absent in females. Lyrifissures ih and ips located by the side of alveoli of seta p^. Gnathosoma: hypostoma excavate medially. The end of chelicera and rutellum very dark. Femur of palpus with blade-like ventral formation. Palpal tarsus long, seta acm and the solenidium arising a well protunde basal tuberculum. Setal formula: 2-1-3-9 + 1 (Fig. 24). Lateral and ventral regions: pedotecta 1 narrow, pedotecta 2-3 and discidium normally developed (Fig. 18). Circumpedal carina long, reaching to the lateral margin of ventral plate. Epimeral and ventral plate without any sculpture. Apodemes simple, they are mostly straight. Epimeral setal formula: 1-0-3-2. All of these setae conspicuously long and strong, but all setae in the anogenital region minute. Two pairs of setae arising on the anterior margin of the genital plates. Legs: All legs tri- and heterodactylous. The setal formulas are normal. Solenidial group of leg 1 (Figs 22, 25> as shown in Fig. 19. Solenidium longer than u) 2* Solenidium of tibia of leg 4 (Fig. 23) arising in the distal half of the tibia. Material examined: Holotype (1358-HO-89): No, 341-1. Vietnam, Da Lat, 20. X. 1988. Berlese samples: litter. Leg, Mahunka, S. - 10 paratypes: from the same sample. Holotype and 8 paratypes (1358-PO-89) deposited in the HNHM, 1 paratypes in the CNC and 1 paratype in the MHNG. Remarks: The new species belongs to a species group which is characterised by three pairs of areae porosae, the filiform sensillus, the interrupted or absent dorsosejugal suture n4
