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 View Figs 3–10 ) 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 View Figs 3–10 , antennomere 2 short, antennomere 3 prolonged, antennomeres 4–10 subquadrate, antennomere 11 twice aslong asantennomere 10; both mandiblesbifid; maxillary palps ( Fig. 5 View Figs 3–10 ) 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 View Figs 1–2 , 3 View Figs 3–10 ) 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 View Figs 3–10 ) with a rounded, flat prosternal process not lobes of female. Scale line: 10.0 mm (3), 5.0 mm (4–10)
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 View Figs 1–2 , 3 View Figs 3–10 ) 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 View Figs 3–10 ) 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 View Figs 3–10 ) 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.
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).
