Abstract

Genus Trimorus Förster is one of the five genera recorded from India under the subfamily Teleasinae (Hymenoptera: Scelionidae). They are egg parasitoids of carabid beetles and are generally encountered in both cultivated and natural landscapes. With 317 species known globally, Trimorus is moderately species-rich. The genus is represented with 32 species from India to date. We came across a couple of unusually robust and large females of Teleasinae, during our recent surveys in West Bengal, having a striking body coloration of yellowish-orange and black. Based on some key morphological characters, the species was identified as an undescribed species of Trimorus. The lack of lateral mesoscutellar spines distinguished it easily from Gryonoides Dodd. The present work documents Genus Trimorus for the first time from West Bengal with description of a new species.
