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

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.

Recognition of the genus Habrocampulum Gauld, 1976 (Hymenoptera: Ichneumonidae: Anomaloninae) from Japan, with a new combination and a key to the species.

First record of the genus Seleucus Holmgren, 1860 (Hymenoptera: Ichneumonidae: Ctenopelmatinae) from the Oriental region, with description of a new species

Abstract The ctenopelmatine genus Seleucus Holmgren, 1860 (Hymenoptera: Ichneumonidae) is recorded from the Oriental region for the first time. A new species, Seleucus taiwanus Shimizu, sp. nov., is described, based on a single female specimen from the highlands of Taiwan. http://zoobank.org/urn:lsid:zoobank.org:pub:280B65CB-8A7C-4F66-A38C-CB7AE0A98EBA

Taxonomic revision of the genus Stauropoctonus Brauns, 1889 (Hymenoptera: Ichneumonidae: Ophioninae) in Japan

The Japanese species of the ichneumonid genus Stauropoctonus Brauns, are revised. As a result, three species are recognized. Stauropoctonus infuscus (Uchida, ) stat. rev., previously synonymized with S. bombycivorus (Gravenhorst, ), is recognized as a valid species and re‐described. Stauropoctonus bombycivorus, which has already been recorded in Japan, is also recognized and re‐described based on Japanese specimens. Stauropoctonus aurantiacus sp. nov. is described based on a single male specimen from Yakushima Island, Kagoshima Prefecture, Japan. Stauropoctonus nigrithorax Lee & Kim, syn. nov. is newly synonymized with S. bombycivorus. Additionally, a key to the Stauropoctonus species and discussions on their phenology and collection methods are provided.

Discovery of the subfamily Lycorininae Cushman & Rohwer, 1920 (Hymenoptera: Ichneumonidae) from Indonesia, based on Lycorina longicauda Shimizu, sp. nov., with a key to the Oriental Lycorina species: Discovery of Lycorininae from Indonesia

The subfamily Lycorininae Cushman & Rohwer is discovered from Indonesia based on a single new species, Lycorina longicauda Shimizu, sp. nov., which can be easily distinguished from any other Lycorina species by its longer ovipositor sheath and colour pattern. We also provide a key to the five species of Lycorina known from the Oriental region.

A systematic revision of the Japanese species of the genus Therion Curtis, 1829 (Hymenoptera: Ichneumonidae: Anomaloninae)

The Japanese species of the genus Therion Curtis, 1829 (Ichneumonidae: Anomaloninae) were revised based on examination of 447 Japanese specimens. Four species are recognized based on morphology and sequence data (mtCOI). Two of them are identified as previously known species: T . circumflexum (Linnaeus, 1758) and T . giganteum (Gravenhorst, 1829). The other two species are described as new: T . carinatum Shimizu & Bennett, sp. nov. and T . nigrigasterum Shimizu, Bennett & Ito, sp. nov. In addition, T. rufomaculatum (Uchida, 1928) stat. rev. is once again synonymized with T. circumflexum . The Japanese species of Therion are easily distinguished from each other by a newly provided key. The lasiocampid moth, Dendrolimus spectabilis (Butler, 1877), is newly recorded as a host of T . giganteum .
