Synonymy

= Phacrylus Schedl, 1938d: 24 View in CoL .

Type of genus

Acorthylus asperatus Brèthes, 1922 View in CoL .

Diagnosis

This genus can be diagnosed from all other Scolytinae by the unique second funicle segment which is much larger than the first.

Female

Eye long and broadly emarginated. Antennae with an enlarged second funicle segment. Antennal club large, with two sutures, septate on both sides, approximately symmetrical. Pronotum with a distinct summit. Asperities on the anterior margin present. Asperities on the pronotal declivity are arranged in concentric giving an obtuse arc-shaped area of asperities. Dorsolateral margin of pronotum rounded. Hypomeron with extensive bifurcating setae. Elytra convex, without any distinct sculpturing.

Male

Similar to female. Aedeagus not examined.

Distribution

South America.

Remarks

Six species known. Although this was not confirmed with any molecular data, this genus is transferred based on the broadly emarginated eye, the bisulcate declivity, but the apical plate of the proventriculus which is wide open, and by the similarity of this genus to Stegomerus which has been confirmed by molecular data to be Corthylini .
