Biology, ecology, and taxonomy of the parasitoids of the families of Austroniidae, Peradeniidae, Proctorenyxidae, Roproniidae, and Vanhorniidae (Hymenoptera: Proctotrupoidea)

“…The fauna of Russia includes 1 genus and 1 species of ichneumons of this family in the Far East (Sakhalin, Kuril Islands). They are found in the Nearctic, Palearctic, and Oriental regions [29][30].…”

“…Some species parasitoids on Coleoptera larvae. Oviposition appears to occur through cracks in decaying wood and the structure of the ovipositor suggests that the female is incapable of drilling through solid wood This author also suggested that oviposition might occur on or into earlier stages of the Eucnemidae host, which would imply that the larva behaves as a koinobiont [34][35]. This parasitoid species has been reared from the larval/pupal chambers of Sorhipis ruficornis (Say, 1823) (Coleoptera: Eucnemidae) in the wood of dead maple.…”

Review of the rare genus Vanhornia Crawford, 1909 (Hymenoptera, Proctotrupoidea, Vanhorniidae) with description of a new species from the Russian Far East

“…The genus was erected for V. eucnemidarum Crawford, 1909, which is the type species by monotypy (Crawford 1909). The type species is widespread throughout North America (Smith 1995;Hogan et al 2019;Kleiner et al 2019) and has recently been doubtfully recorded in South Korea (Choi and Lee 2012). Another species of the genus, V. leileri Hedqvist, 1976, was described from two specimens collected in Sweden (Hedqvist 1976), the female holotype and a paratype reported as a male, although the latter has later been revealed to be a female lacking the ovipositor (Forshage et al 2016).…”

Integrating multiple sources of biodiversity information greatly expands the range of a rare species of Hymenoptera (Vanhorniidae)

“…1C), deeply pitted mesosoma (Fig. 1B) and long exserted ovipositor, projecting anteriorly from the base and housed in a ventral groove (Champlain 1922, Crawford 1909, Deyrup 1985, Haines 2008, Johnson 2017, Keim 2017, Kleiner et al 2019, Townes and Townes 1981). Vanhorniidae contains a single genus Vanhornia Crawford and includes three described species, V. eucnemidarum Crawford, 1909, V. quizhouensis (He & Chu, 1990) and V. leileri Hedquist, 1976 (Crawford 1909, He and Chu 1990, Hedqvist 1976, Kozlov 1998).…”

Vanhornia eucnemidarum is the only North American species, with a known range including the states of Florida, Georgia, Kansas, Kentucky, Maine, Maryland, Michigan, New York, North Carolina, Ohio, South Carolina, Tennessee, Virginia and West Virginia and the Canadian provinces of Ontario and Quebec (Champlain 1922, Crawford 1909, Deyrup 1985, Haines 2008, Johnson 2017, Keim 2017, Kleiner et al 2019, Townes and Townes 1981). Along with North American records of V. eucnemidarum , this species has also been recorded in South Korea (Choi and Lee 2012).…”
