Hymenoptera Evanioidea Baissidae

Abstract

Humiryssus Lin, 1980 is a Cretaceous genus with Humiryssus leucus Lin, 1980 as its type species established based on a tiny wasp from the Lower Cretaceous (Hauterivian-Barremian) Laocun Formation at Laocun, Jiande, Zhejiang Province, eastern China and originally placed in the extinct family Paroryssidae (Hymenoptera: Tenthredinoidea) (Lin, 1980). It was later treated jointly with the genus Manlaya Rasnitsyn, 1980 (Evanioidea: Gasteruptiidae: Baissinae) because the characters shown in the line drawing by Lin (1980) indicate a close relationship of the genus to Manlaya (Rasnitsyn et al., 1998). However, Zhang & Rasnitsyn (2004) considered it to be a separate genus within the Baissinae, which is now considered as an independent family under the Evanioidea (e.g., Li et al., 2018; Jouault et al., 2020, 2021).
