Chrysis maculicornis species-group

Chrysis (Cornuchrysis) maculicornis species-group: Linsenmaier 1959: 173 (partim).

Chrysis maculicornis species-group: Kimsey and Bohart 1991: 353 (key), 341 (fig. 111m).

Diagnosis.

The maculicornis species-group is characterised by having males with shortened F1 and F2, F1 slightly longer than F2, but shorter than F3; females with F1l/w ≈ 2.0; MS usually 0.2-1.3 MOD; face slightly wedge-shaped in frontal view.

Description.

Male F1l/w = 1.0-1.4; F1 slightly longer than F2, but shorter than F3. Female F1l/w ≈ 2.0. Scapal basin micropunctate or microridged medially. TFC well developed, biconvex. Mid ocellus sometimes lidded. MS usually 0.2-1.3 MOD. T3 in female sometimes with prepit bulge; pit row usually well developed. T3 with four sharp apical teeth. Black spots on S2 large and sub-oval, separated medially and sometimes connected to lateral margins.

Species included.

Kimsey and Bohart (1991) in the species-group diagnosis included fifteen Palaearctic species, but in their checklist reported twenty-two Palaearctic species, one Oriental ( C. perfecta Cameron, 1897) and one Afrotropical ( C. rhinata Bohart, 1988). The list of Palaearctic species needs to be further verificated, because some species have been included in the cerastes species-group (e.g. C. subdistincta Linsenmaier).

Distribution.

Palaearctic, Oriental and Afrotropical regions.

Remarks.

Linsenmaier (1959, 1968) included in the maculicornis species-group only the species with shortened F1 and F2 and flagellomeres yellowish beneath in males (e.g. C. maculicornis Klug, 1845, C. fulvicornis Mocsáry, 1889, and C. stigmaticornis Linsenmaier, 1968). Kimsey and Bohart (1991) added the species close to C. annulata du Buysson, 1887 (e.g. C. blanchardi Lucas, 1849; C. distincta Mocsáry, 1887; C. rectianalis Linsenmaier, 1968, etc.) into the maculicornis species-group, whereas Linsenmaier (1959, 1968) included them in the cerastes species-group. In this paper we follow Kimsey and Bohart’s (1991) interpretation of the maculicornis species-group.
