Genus Acanosema Кiеffеr, 1908

Acanosema Kieffer, 1908: 360 , 367, 407.

Type species: Acanosema rufum Кiеffеr, 1908 , by original designation.

REMARKS. Kieffer (1908) differs Cardiopsilus from the Acanosema by long scapus which simple at the top (scapus shorter, with two lamellae on the top in

Acanosema ) and setose eye (bare in Acanosema ). The new species described below demonstrate that the scapus has in reality restricted taxonomic value since the other two features are still could be used as diagnostic. However, these two features

(pubescence of eye and shape of scapus top) are variable in the closest genera –

Acanopsilus (considering the two new species described below), Sinacra and

Psilomma ( Chemyreva & Kolyada, 2020) . On the base of these evidences we suggest that two genera Acanosema and Cardiopsilus can be classified in a single genus Acanosema with two subgenere: Acanosema s. str. and Cardiopsilus Kieffer.
