Revision of the Taiwanese species of the genus Leptophion Cameron, 1901 (Hymenoptera: Ichneumonidae: Ophioninae), with a discussion of their phenology and distribution

Abstract

We revise the Taiwanese species of the ophionine genus Leptophion Cameron, 1901. As a result, three species, including a new species, are recognized. Two of them were identified as L. maculipennis (Cameron, 1905) and L. radiatus (Uchida, 1956), both of which had been previously recorded in Taiwan; we redescribe them based on Taiwanese specimens. We describe a single new species as L. giganteus Shimizu & Watanabe, sp. nov. The phenology and distribution of the species are briefly discussed. A key to the Taiwanese species of Leptophion and additional couplets to the key proposed by Gauld & Mitchell (1981) are also provided.

Description of a new species and revised key to species of the Enicospilus antefurcalis species-group from Japan (Hymenoptera: Ichneumonidae: Ophioninae)

“…The morphological terminology mainly follows GAULD & MITCHELL (1981) and GAULD (1991), and the terminology for surface microsculpture follows EADY (1968). The abbreviations and indices used in this paper mainly follow SHIMIZU & WATANABE (2015), SHIMIZU et al (2016), as listed below.…”

“…Although some larvae of Scarabaeidae (Coleoptera) and Tenthredinidae (Hymenoptera) were reported as hosts (Thompson ; Townes ), all reliable records of their hosts are only from Lepidoptera (Shimizu et al . ). Most ophionine wasps have characteristic body adapted to nocturnal habits, the “ophionoid facies” (Gauld & Huddleston ), and are attracted by light, like many other nocturnal ichneumonoid wasps (e.g.…”
