Genus Isorhombus Förster, 1856

(junior synonym of Platygaster Latreille, 1809)

Isorhombus Förster, 1856: 107, 113. Type species Isorhombus hyalinipennis Ashmead, 1887 by first subsequent inclusion. Junior synonym of Platygaster Latreille, 1809 – Fouts 1924: 51.

Remarks

The genus Isorhombus was characterized by a diamond-shaped head in frontal view and a three-merous clava. The type species is Isorhombus hyalinipennis Ashmead, 1887 . Based on Ashmead’s type, Fouts (1924) synonymized it with Platygaster . Ashmead’s interpretation differed from Förster’s concept, which was more similar to Leptacis than to Platygaster .

Debauche (1947) proposed the name Anacoryphe to refer to Isorhombus sensu Förster, with Anacoryphe orchymonti Debauche, 1947 as the type species. The type specimen is in RBINS. Anacoryphe was later synonymized with Leptacis by Kozlov (1978). Evidence that Debauche correctly interpreted Förster’s concept is exemplified by two specimens in the NHMW labelled as Isorhombus fulvipes Förster. This is a nomen nudum, and the specimens were subsequently identified by Lars Huggert as Leptacis orchymonti .
