Distribution. Honduras.

Etymology. The specific epithet is derived from the Latin seta meaning “bristle” and rotundus meaning “rounded”. It refers to the setae rounded dilated on the apex of the genital plate present in males. This characteristic is unique to this species.

Variation. No significant variation was observed in the examined specimens.

Host. Unknown.

Remarks. Calopompilus setaerotundus sp. nov. belongs in the C. pyrrhomelas species-group, because it has a fore wing with a long anal lobe, the hind tibia bears distinct teeth, and the body has dense pubescence. Following Townes’ key (1957, pages 13-14) this species keys to C. feroculis (Banks) , a species found in the Southeastern USA. The female of C. setaerotundus differs from that of C. feroculis by having the antenna yellow (black in C.

feroculis ). Moreover, the propodeum is smooth in C. feroculis (striate in C. setaerotundus ). The male of C. setaerotundus differs from that of C. feroculis in that the male of C. feroculis lacks a whitish spot on the outer margin of the eye; also, it has the clypeus rugose, the vertex less convex or without the prominent/ elevated ocelli, and the fore tibia fully black. The male of C. setaerotundus has a whitish spot on the outer margin of the eye, the clypeus is polished, although it is covered by long pubescence, the vertex is extended and convex, and the venter face of the hind leg is pale brown.
