Description of the male of Misetus strumiai Di Giovanni, Scaramozzino & Diller, 2018 (Hymenoptera, Ichneumonidae, Ichneumoninae, Phaeogenini) from Italy

Abstract

The genus Misetus Wesmael, 1845 is a small taxon of the subfamily Ichneumoninae, tribe Phaeogenini. The genus can be distinguished from other genera of the tribe by having mandible with two teeth, clypeus with more or less developed median apical tooth, genae short and sublinearly narrowed behind eyes in dorsal view; males are characterized by thyridia large and placed far off the base of metasomal tergite II; females are easily recognized by metasoma elongate and compressed apically, apical margin of last metasomal tergite more or less concave and ovipositor short and bent upwards (Selfa & Diller 1994, 1995, Di Giovanni et al. 2018). Misetus includes seven known species, six of which occur in Europe (Wesmael 1845, Kusigemati 1974, Kolarov 1985, Selfa & Diller 1995, Di Giovanni et al. 2018) and one in Japan and South Korea (Kwon et al. 2011; Yu et al. 2012). Misetus strumiai Di Giovanni, Scaramozzino & Diller, 2018 was described recently from females known only from the island of Montecristo (Italy, Tuscany) (Di Giovanni et al. 2018, Di Giovanni & Scaramozzino 2019). Here we described the male of this species and provide a comparative diagnosis with other known males of European members of the genus.
