Austrocarabodes rimosus sp. n.

Measurements. - Length: 529 µm, width: 295 µm.

Prodorsum: Rostrum widely rounded, lamellar cuspis also wide, they are connected by a well-observable transverse lamella. Rostral setae thin, short, only slightly phylliform. Lamellar setae very wide, with very long marginal spines (Fig. 28). Interlamellar setae phylliform, originating close to each other in the interlamellar region, directed outwards. They have two lines (Fig. 25). Sensillus comparatively short, bent backwards, its outer surface well spinulose. Interlamellar region with some longitudinal ribs.

Notogaster: Dorsosejugal suture straight medially, in the dorsosejugal region without a hollow. Median part of notogaster framed by a stronger rib, inner part with some longitudinal ribs and foveolae. Fourteen pairs of phylliform notogastral setae present, setae c2 directed forwards, all others backwards. All setae medially with one vein. Surface and margin of setae without spines or spicules (Fig. 25).

Lateral part of prodorsum: Rostrum smooth, lateral part foveolate. Tutorium weakly developed, without cuspis. Pedotecta I large.

Coxisternal region: Mentum foveolate only anteriorly. Coxisternal region also foveolate laterally. Epimeral setal formula: 3 —1—3— 3.

Setae 1a, 1c, 2a and 3a very short, all others long. Apodemes short, borders hardly observable (Fig. 27).

Anogenital region: Anal plates ornamented by some strong ribs and tectum. All setae of anogenital region thin and simple. Lyrifissures lad opening very far from anal aperture.

Legs: All tarsi have very short and thick setae u (Fig. 26). Setae V genu of leg II phylliform (Fig. 30).

Type-material: Holotype ( 1197-HO-87 ): Angola, Environ Malange , forest litter and moss, 12. V. 1980, leg. Z. Szabó. 5 paratypes from the same sample. Holotype GoogleMaps and 4 paratypes ( 1197-PO-87 ) in the HNHM GoogleMaps , 1 paratype in MHNG. GoogleMaps

Remarks: On the basis of the very wide lamellar setae the new species belongs to the " tarandus " species-group by its anteriorly directed setae c2.
