Coriacephilus Schedl, 1939b: 339 ( Fig. 9 )

Type of genus

Stephanoderes coriaceus Eichhoff, 1878 .

Diagnosis

Coriacephilus can be separated from other Cryphalini by the combination of cylindrical third tarsal segments, deeply emarginated eye, antennae with sutures and septum, and bifurcating setae on the hypomeron.

Female

Eye deeply emarginated. Antennae with procurved sutures, the first darker indicating a complete septum. Antennae with four funicular segments. Hypomeron with bifurcating setae in most species. Pronotal disc present and prominent in all species with a mixture of hair-like setae pointing anteriorly. Elytra with flattened interstrial bristles and sparse hair-like interstrial ground vestiture. Proventriculus not examined. Aedeagus not examined.

Male

Unknown.

Distribution

All species are known from Southeast Asia.

Remarks

Five species known. No material was available for the study of internal morphology. All species are known from very few specimens. However, the validity of this genus being separate from Cryphalus and Cosmoderes is strongly supported with genetic evidence, placing Coriacephilus coriaceus as sister to Xyloterini . They are morphologically very similar to Cryphalus , most easily distinguished by the third tarsal segment which is not emarginated in Coriacephilus . A study of the internal morphology, or better genetic resources are needed to provide better diagnostic characters for the reliable determination of this genus.
