Oligotergus Bierig, 1937

Type species.

Philothalpus (Oligotergus) oculatus , fixed by monotypy ( Herman 2001).

Species included.

The genus includes 20 species listed in Newton (2021) and Oligotergus nigricornis comb. nov. based on the results of the phylogenetic analysis presented in this paper. For a complete taxonomic history of the genus see Herman (2001).

Diagnosis.

The genus is not revised so the following characters (in combination) should be considered only as a partial list: left mandible with single tooth; antennomere 1 less than twice as long as antennomere 2; eyes large; pronotum with dense micropunctures (not in all species).

Remarks.

The type species was not available for the phylogenetic analysis. A formal revision of the genus is forthcoming (Chatzimanolis in preparation) where all species belonging to this genus will be treated and illustrated.
