Auxicerus aethiops Jakowleff 1900: 38.
Holotype
BOLIVIA: ♂ [no other data], BL 16 mm ( ZIRAS).
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.
