Review of the mandibularis group of the genus Dolichomitus (Hymenoptera, Ichneumonidae, Pimplinae)

Abstract

The mandibularis group of the genus Dolichomitus is reviewed. Three species are recognized, including a new species, Dolichomitus flavicrus sp. n. from Japan. The new species is closely related to Dolichomitus khasianus Gupta & Tikar, in having an entirely blackish underside of the metasoma, but can be separated from the latter by the smooth antero-median part of the first metasomal tergite between the latero-median carinae and a short longitudinal dark stripe on the posterior surface of the fore femur. A key to species of the mandibularis group is provided. Mitochondrial COI gene sequences were generated for D. mandibularis (Uchida) and D. flavicrus sp. n. to permit future comparisons.

Two species of Dolichomitus Smith, 1877 (Hymenoptera, Ichneumonidae, Pimplinae) parasitizing borers of Juglans mandshurica Maxim. and a key to species known from China

“…Dolichomitus Smith, 1877(Ichneumonidae Latreille, 1802, Pimplinae Wesmael, 1845) is a relatively large genus of Darwin wasps, comprising 85 species (Choi et al 2016;Yu et al 2016;Matsumoto 2018;Araujo et al 2020;Di Giovanni et al 2021). The Oriental species were revised by Gupta & Tikar (1976).…”

Five new species of Dolichomitus Smith from the tropical Andes, with a key for the South American species (Hymenoptera, Ichneumonidae, Pimplinae)

“…These studies indicate that unsampled areas have great potential for revealing new species to science, especially considering that few areas of South America were sampled adequately (Gómez et al 2009). Because of their long ovipositors and large bodies, Dolichomitus wasps are one of the most conspicuous and well-known genera in the Ichneumonidae, with more than seventy known species in the world (Matsumoto 2018). There are 15 species in the Neotropical region, with eight species occurring in South America: D. annulicornis (Cameron, 1886); D. bivittatus Townes, 1975;D.…”
