Two genera of hybrizontine ant parasitoids (Hymenoptera: Ichneumonidae) collected by light traps

Abstract

The subfamily Hybrizontinae Blanchard, 1845 (Hymenoptera: Ichneumonidae), the endoparasitoids of ants, have been observed during the daytime. In this subfamily, there is only one record, that of Hybrizon buccatus (de Brebisson, 1825), collected by the light trap. We record the capture of two hybrizontine species belonging to the genera Neohybrizon Hisasue & Konishi, 2019 and Ogkosoma Haupt, 1913 at the light trap for the first time. Among them, O. cremieri (Romand, 1838) is considered to be a crepuscular species, which is probably related to the biology of the host ant.
