(Malaysia); 2: Aediotorix cf. petersi GEBIEN , 1921 (Philippines) Description (male): Body length 16.0–17.5 mm. Body and appendages unicoloured dark brown to black, elytra sometimes indistinctly paler; surface of head and pronotum dull, of elytra somewhat shining; without regular setation. Head ( Fig. 3 ) with coarse, confluent punctation; genae above antennal insertion without punctation and shining; clypeal suture distinctly impressed; clypeus excavated; temples considerably broadened and separated from the narrow neck; proportions of antennomeres see Fig. 4 , antennomere 2 short, antennomere 3 prolonged, antennomeres 4–10 subquadrate, antennomere 11 twice aslong asantennomere 10; both mandiblesbifid; maxillary palps ( Fig. 5 ) with broadened last segment; mentum pentagonal with an impression on each side and with a weak longitudinal keel medially; underside of head with rounded gular impression. Pronotum ( Figs 1 , 3 ) 1.3 times wider than medially long, with coarse and confluent punctation as on head, surface somewhat uneven; all margins bordered and shining, lateral margin distinctly crenulate; propleures with punctation sparser than on disc. Prosternum ( Fig. 8 ) with a rounded, flat prosternal process not lobes of female. Scale line: 10.0 mm (3), 5.0 mm (4–10) Figs 3–10. Malayoscelis gen. n. gebieni sp. n. 3: dorsal view; 4: antenna; 5: maxillary palp; 6: anterior leg of male; 7: posterior leg of male; 8: prosternal process; 9: aedeagus; 10: gonostyles and last coxite distinctly surpassing posterior margin. Mesoventrite with dull and confluent punctation. Metaventrite medially impunctate and shining, with a distinct longitudinal line medially. Scutellum only with fine and separate punctures. Elytra ( Figs 1 , 3 ) long and parallel-sided; with traces of 5–7 keels, these keels shining, between the keels with shallow and confluent punctation, surface with additional microgranules; epipleura regularly narrowed toward apex, without separated constriction, shining and without puncturesbut with microgranulesin the humeral part. Wingsfully developed. Abdomi - nal ventrites unpunctured, but with leather-like microstructure, last visible ventrite unbordered and without distinct modifications. Legs ( Figs 6–7 ) with the anterior and middle femora with a single, posterior femora with 2 distinct teeth shortly before apex; anterior tibia bent, posterior tibia straight; all tibiae with crenulate inner side; anterior and middle tibiae with distinctly hooked inner apex; apex of tibiae without spurs and with comb-like setae; tarsal segments not dilated in males; claw segment of all legs longer than basal segments combined; trochanter of all legs without spines or other peculiarities; surface of all legs nearly impunctate and shining. Aedeagus ( Fig. 9 ) quite small in comparison with the body length, connate parameres finger-like. Sexual dimorphism: Not striking. Females also with armed femora, but anterior tibia somewhat straighter, anterior and middle tibia without hooked inner apex. Etymology: Thistaxon isnamed in honour of H ANS GEBIEN (1874–1947), whose monograph of the Pycnocerini (1904) was the first of his numerous and substantial contributions towards tenebrionid taxonomy. Fig. 11. Distribution of the known genera of the Oriental Pycnocerini Biology: Adult beetleswere collected in standing trunksof dead broadleaved trees, together with larvae and pupae. The rotten, white coloured substrate was said to be extremely dry. A species of Aediotorix wasfound syntopically (B EČVÁŘ, personal communication).
