M. dispar BALOGH, 1958 and M. ceylonica BALOGH, 1970 have bifurcate sensillus. The costulae of M. simplex CSISZÁR, 1961 run nearly parallel, far from each other (costulae of the new species run near to each other and arched forwards). Nesoribatula rotunda sp. n. (Figs 42-45) Measurements — Length : 574-647 u,m, width : 402-492 u.m. Prodorsum: Rostral apex elongate, nasiform, beside it a small incision present on each side, but visible only in lateral view (Fig. 44). Lamellae strong, thinner prelamellae present, rostral setae arising on them. Distal part of prelamella strongly arched. Rostral setae setiform, lamellar and interlamellar ones blunt at tip. Ratio of them: in >• le > ro. Sensillus small, with capitate head. Notogaster: Very large, nearly round (Fig. 42). Pteromorphae absent, dorsosejugal suture slightly convex medially. Thirteen pairs of short but strong, slightly thickened notogastral setae, all finely roughened. Four pairs of pori (or very small sacculi) also well visible, P x originating behind the glandular pore. Coxisternal region: Median part of all epimeres ornamented by spots. Epimeral borders and two apodemes (ap. sej. and ap. 3) well observable (Fig. 43). Epimeral setae fine, setae lb longer than the others. Setae lc arising on pedotecta 1. Discidium narrow, setae 4c arising on its outer surface. Anogenital region: Genital aperture much smaller than anal ones. All setae very short, fine, setae ad x and ad 2 in postanal position. Legs: All legs tridactylous, median claw much bigger than lateral ones. Tibia of leg I with a large process (Fig. 45), solenidia q> x and <p 2 arising on it. Type material: Holotype (1282-HO-88): No. 105 ; 19 paratypes: from the same sample. Holotype and 15 paratypes (1282-PO-88) deposited in the HNHM, 2 paratypes in the MHNG and 2 paratypes: SUM. Remarks : The relationship of the new species is rather uncertain, its ranging to the genus Nesoribatula AOKI, 1964 is only provisional, however, on the basis of its habitus, the position of the small (?) sacculi, and the form of the notogastral setae it is distinguished from all known related species. Scheloribatoides gen. n. Diagnosis: Family Scheloribatidae. Rostrum nasiform, laterally excavate. Lamellae and prelamellae well developed, prelamellae compose a free lamelliform cuspis anteriorly, rostral setae arising on them. Sensillus fusiform, originating laterally. Dorsosejugal suture convex, complex medially. Ten pairs of well-observable, but fine notogastral setae and four pairs of small sacculi present. Epimeral setal formula: 3-1-3-3. Anogenital setal formula: 4-0-2-3. Lyrifissures iad in adanal position. Legs monodactylous. Type species: Scheloribatoides lame Ha tus sp. n. Remarks : The new taxon has four very characteristic features: 1. Free lamelliform cuspis of prelamella, 2. True notogastral setae, 3. Absence of the aggenital setae and 4. Monodactylous legs. However, on the basis of the first character it is stands very far from all the known Scheloribatoid genera.
