Africa, Namaqualand, Katdoringvlei^ 31O07' S - 17°52' E, 28.8.1979, E-Y. 1605, ground traps 62 days baited with feces, leg. ENDRCDY-YOUNGA. Types preserved in the Transvaal Museum in Pretoria, paratypes also in the Hungarian Natural History Museum, Budapest. Similar to A. haematicus Boheman, but genae rounded and not produced beyond eyes. Basal joint of posterior tarsi about as long as three following joints together, etc. Orocanthus group n. of Aphodius Clypeus deeply emarginated on apex, both sides beside emargination rounded. Head simply convex, without tubercle or carina, surface not granulated. Pronotum punctate, posterior angles not emarginated, basis bordered. Scutellum triangular, on basis not parallel. Striae of elytra deep, but on apex not distinctly deeper than on disc. This new group may be fitted in mey key of groups (Folia ent.hung., 42, 1980: 36-39) after couplet 64 (52), but differing in form of clypeus, in sculpture of elytra, also in small body-size and dark colour, etc. Type of group: Aphodius helenae sp.n. Aphodius (Orocanthus) helenae sp.n. Black, shiny, apex of clypeus, antennae (excepting a black knob), sides of elytra and legs extensively light. Clypeus strongly emarginated on apex, beyond emargination rounded, genae not separated from sides of clypeus, rounded, indistinctly produced beyond eyes. Frontal suture very distinct, without tubercle, surface finely reticulated and very finely punctated. Pronotum broader than long, sides slightly rounded, broadest at posterior angles. Basis strongly bordered. Surface everywhere densely covered with rather big punctures mixed with very fine ones. Scutellum elongate triangular. Elytra rather short, distinctly shorter than twice breadth together, oval, also sides slightly rounded. Striae deep everywhere, on apex not deeper than on disc, with rather strong punctures. Intervals convex, reticulated and finely punctated. Anterior tibiae tridentate, posterior ones with two distinct oblique carinae, apex strongly enlarged with strong bristles of equal length. Basal joint of posterior tarsi somewhat shorter than upper thorn and about as long as three following joints together. Length: 2.5-3 mm. - Examined material 11 specimens. Types: Holotype and 10 paratypes: S. Africa, Cape Prov., Elandsdrift, 34°39' S - 19°53'E, E-Y. 1747, 24.2.1981, leg. ENDRODY-YOUNGA. Types preserved in the Transvaal Museum in Pretoria, two paratypes in the Hungarian Natural History Museum, Budapest. I dedicate this new species to the excellent collaborator of my són, Miss Elaine Labachange assistant in Pretoria.
