The examination also showed that on the apicate end of the elongate notogaster there is an unpaired porose area, which has been overlooked so far. The same is found on the type specimens of magniporosus and africanus, as on the specimens from Kenya (Figs 5-9). The exemplars from Kenya are very slightly different from the type of africanus, like in the shape of the excision of rostrum, in the shape of sensillus (Figs 8-11), though the differences may well be forgotten altogether. The specimens from Kenya include both females and males, here I observed that the porose area of the males is small than that of the females. It is rather striking in the case of A2 and A3 (Figs 5-7). There is also some difference is the size of the two sexes - female length: 653 pm, width: 459 pm; male length: 594 pm, width: 427 um. Zygoribatula galula sp. n. Measurements — Length of body (female): 381-398 pm, (male): 365 pm; width of body (female): 250-255 pm, (male): 196 pm. Prodorsum: Rostrum elongated, with sharply pointed apex. Lamellae comparatively short, but well sclerotized, lamellae and sublamella equally well developed. Sublamella also well visible. Rostral setae setiform, with fine distal end, lamellar and interlamellar ones blunter at tip, without narrowed, fine distal end. All three pairs well ciliate, nearly equal in length. Lamellar setae not reaching to the rostral apex. Sensillus rounded, clavate, its peduncle comparatively short, with scopulate head. Lateral part of prodorsum: Tutorium long, without true cusp (Fig. 15). Prelamella absent. The distal end of lamellae well rise from the lamellar surface. The surface of pedotecta I striated, setae 1c arising on them. Circumpedal carina well developed, but ending far from the lateral margin of the ventral plate. Notogaster: Wide, pteromorphae not protruding anteriorly and laterally. Anterior notogastral tectum slightly convex medially. Humeral part of the notogastral surface ornamented by sharp, irregular striae, other part with very fine, hardly observable, irregular alveoli or short striae (Fig. 12). Four pairs of comparatively large (Aa largest of all) porose areas and fourteen pairs of notogastral setae present. Among the notogastral setae great difference exist, setae cj only half as long as Six pairs of setae arising on the anterior part of notogaster thicker than the rest and bacilliform, the others simple and much thinner. Ventral side (Fig. 13): Mentum characteristically striated (Fig. 14). Epimeral setal formula 3-1-3-3. Seate lc, 3c and 4c much longer than the others. Epimeral region ornamented by alveoli, which also present on the ventral plate. Pedotecta 2-3 triangle, discidium well protruding anteriorly, setae 4c arising on their lateral apex. Genital and aggenital setae short, lyrifissures iad in preanal position. Legs: Typical for the genus. All legs tridactylous. Material examined — Holotype: Kenya. Leg. S. Mahunka and L. Mahunka-Papp, 2 specimens from the same sample. Holotype (1659-HO-01) deposited in the Hungarian Natural History Museum, Budapest, with identification numbers of the specimens in the Collection of Arachnida, 1 paratype in the Museum d'Histoire Naturelle, Genève. Remarks — On the basis of the notogastral heterotrichy the new species belongs to the Z. heterotricha-group. The nominate species of this group (Z. heterotricha Mahunka, 1978) was described from Dominican Republic (Mahunka 1978a) and it was mentioned also from Mauritius (Mahunka 19786). Two other species (Z. robusta Groebler, 1993 and Z. globosa Mahunka, 2000) belong also to this group (Groebler 1993). In the distinguishing of these species are the best features the ratio of setae ci and cj and the lent-
