Scheloribatoides lamellatus sp. n. (Figs 46-49) Measurements — Length: 260-308 urn, width: 184-226 u.m. Prodorsum: Rostrum with wide, nasiform apex, its anterior margin blunt or with two small teeth (Fig. 46). Beside the apex two hollows or small incisures present. Lamellae wide, before the prelamella a tubercle present, lamellar setae arising on them. Prelamellae arched (Fig. 48). Ratio of prodorsal setae: le >• in > ro. All three pairs ciliate, the anterior two pairs setiform, the interlamellar setae blunt at tip. Sensillus short, its head large, fusiform, well ciliate. Notogaster: Very wide in dorsal view, pteromorphae rounded laterally. Ten pairs of fine notogastral setae present. Lateral part of podosoma: Considerable part of this surface distinctly granulate (Fig. 48). Pedotecta 1 narrow, setae lc arising on its margin. Coxisternal region: Some irregular fields on the epimeres present. Apodemes well, epimeral borders hardly observable. All epimeral setae fine and short (Fig. 49). Anogenital region: Genital and anal apertures originating far from each other, latter much broader than the other one. All setae fine and short, setae ad

x and ad

2 in adanal, setae ad

3 in preanal position. Type material: Holotype (1283-HO-88): No. 105; 34 paratypes: from the same sample. Holotype and 30 paratypes (1283-PO-88) deposited in the HNHM, 2 paratypes: MHNG and 2 paratype: SUM. Remarks : The differential diagnosis is given after the generic diagnosis. MochJozetes africanus sp. n. (Figs 50-52) Measurements — Length : 458-550 u.m, width : 376-394 ;j.m. Prodorsum: Rostrum conical, lamellae broad, their cuspis well developed, it extends anteriorly beyond translamella, with a distinct smaller lateral and a bigger median teeth, both rounded. Translamella also broad, slightly produced medially. Prodorsal setae, first of all setae in, very long, their ratio ;'// > le > ro > ex. Sensillus short, the head globular, rounded, finely spiculate. Tutorium curved forward (Fig. 51), not reaching to the insertions of rostral setae. Notogaster: Dorsosejugal suture interrupted medially, it reaches to areae porosae sejugales on both sides. Notogastral integument smooth, but on the pteromorphae some radiate lines observable. Five pairs of notogastral areae porosae and ten pairs of minute alveoli present. Among areae porosae Aa\ opening very far from Aa; A

z elongate, ribbon-shaped, the anterior four pairs nearly circular (Fig. 50). Ventral side: Main characters are very similar to those of Mochlozetes penetrabilis GRANDJEAN, 1930, however, the epimeral setae much longer than in the preceding species and discidium well angulate laterally (Fig. 52). Circumventral areae porosae as shown in Fig. 53. Genital setae also very long, ciliate, anal and adanal ones short and simple. Legs: All legs tridactylous (Fig. 54). Type material: Holotype (1284-HO-88): No. 105; 1 paratype: from the same sample. Holotype in the HNHM, paratype: MHNG. Remarks : Four species of the genus Mochlozetes GRANDJEAN, 1930 were heretofore known, all from the New-World. The new species is closely related to the others, however, it is distinguished from them by the position of Aa and Aa' areae porosae and the length of the genital and epimeral setae.
