Genus Carinostigmus Tsuneki, 1954 View in CoL

Carinostigmus Tsuneki, 1954:3 View in CoL .

Type species: Stigmus congruus Walker, 1860 View in CoL , by original designation.

Perissostigmus Krombein, 1984:18 View in CoL , as subgenus of Carinostigmus View in CoL . Type species: Carinostigmus bucheilus Krombein View in CoL , by original designation and monotypy.

Diagnosis. Mandibles bi or tridentate; labrum subtriangular, apically rounded; scapal basin of face shallow; median carina or ridge of lower frons produced into a spine or T-shaped hook; clypeus bare, without any silvery setae; eyes margined with broad, pitted groove and carina; median longitudinal ridge present on lower frons; head well developed behind eyes; occipital carina present, complete to midventral line of head and separated from hypostomal carina; notauli well developed, sometimes short; omaulus continued ventrally by a sulcus which ends near anteroventral margin of pleuron or in large, anterior, circular depression; acetabular carina and subomaulus absent; pitted hypersternaulus present; fore tarsal rake absent in females; stigma large, about three times as long as high, covering considerably less area than marginal cell; two submarginal cells present; hind wing media diverging well beyond cu-a; metasoma in dorsal view with petiole much longer than female pygidial plate present, oval to tear drop-shaped in outline ( Bohart & Menke, 1976).

Within Stigmina, Carinostigmus can be distinguished from other genera by the following subset of characters: Metasoma in dorsal view with petiole much longer than wide; acetabular carina absent; omaulus present, continued ventrally by a sulcus which ends near anteroventral margin of pleuron or in large, anterior, circular depression; eyes margined with broad, pitted groove and carina; median longitudinal ridge present on lower frons ( Bohart & Menke 1976).

Distribution. Oriental, Ethiopian and Palearctic regions ( Pulawski, 2019).
