Material examined Holotype BOLIVIA : [no other data], BL 16 mm ( ZIRAS ). Remarks In his revision of the genus Auxicerus , Weinreich (1963) did not examine the types of A. platyceps and A. aethiops and considered A. aethiops quite similar to A. platyceps . However, the holotype of A. aethiops has comparatively longer mandibles in combination with a narrow head and a less acute ocular canthus and lacks the longitudinal depressions on the pronotal disc (compare Fig. 2 A–B). Additionally, in A. aethiops the elytral surface is entirely shiny and uniformly punctate (in A. platyceps the elytral surface is shiny only along the suture, elsewhere opaque; and the punctures are larger near the suture). Thus, A. aethiops is considered here as a valid species. Geographical distribution Bolivia .
