Li, Xi-Ying, Achterberg, Cornelis van & Tan, Ji-Cai, 2013, Revision of the subfamily Opiinae (Hymenoptera, Braconidae) from Hunan (China), including thirty-six new species and two new genera, ZooKeys 268, pp. 1-186 : 28-29

Genus Coleopioides van Achterberg & Li gen. n. Figs 63-84

Type species.

Coleopioides postpectalis sp. n.

Etymology.

From the generic name " Coleopius " and the addition “oides”, because it is superficially similar to the genus Coleopius Fischer.

Diagnosis.

Face without tubercles; scapus, fore coxa and trochanter at most weakly compressed; epistomal suture without large depressions; inner sides of antennal sockets normal, not protruding; labrum exposed; clypeus truncate ventrally and hypoclypeal depression present (Figs 68, 78); mandibles long and slender (Fig. 79); scutellar sulcus usually rather wide (Figs 65, 75); at least part of postpectal carina present medio-ventrally, but absent in Coleopioides diversinotum ; notauli complete (Fig. 65) or largely absent (Fig. 75); mesoscutum with medio-posterior depression (Fig. 75); propodeum with a transverse carina subbasally and with long medio-longitudinal carina (Figs 65, 76); precoxal sulcus wide and crenulate (Figs 63, 73); second submarginal cell elongate, vein 3-SR 1.5-1.8 times as long as vein 2-SR (Figs 64, 74); second and third metasomal tergites more or less enlarged, longer than following segments; dorsope absent; laterope distinct; second and third tergites enlarged, longer than following segments (Figs 66, 76); second metasomal suture absent or superficially impressed and smooth; third tergite more or less sculptured (but may be largely smooth); epipleuron of third metasomal tergite slightly differentiated from notum and without lateral crease; fourth metasomal tergite well exposed.

Biology.

Unknown.

Notes. Both new species are similar to Coleopius Fischer because of the presence of the hypoclypeal depression, the short metasoma and the shape of the clypeus. The long second submarginal cell (vein 3-SR 1.5-1.8 times vein 2-SR; shorter in Coleopius ), the similar third epipleuron and notum (epipleuron distinctly less sclerotized in Coleopius ), and the third tergite about as long as second tergite and without sharp lateral crease (lateral crease present in Coleopius ) indicate that they do not belong in Coleopius . The new species differ from the similar genus Bitomus Szépligeti by the same character states, except that the second submarginal cell is intermediate. The new genus Coleopioides belongs to a separate basal group in the tribe Opiini together with Areotetes gen. n., according to the molecular data of the nuclear 28S marker of both species. Areotetes gen. n. shares the medio-longitudinal carina and the areolate posterior part of the propodeum with Coleopioides , but differs by having the carinula of the hind tibia, the crenulate posterior groove of the pronotum and the absence of the malar suture and of the depressions behind the antennal sockets.
