Notes on the biology, morphology and generic placement of “Hellwigia” obscura Gravenhorst (Hymenoptera: Ichneumonidae, Ophioninae)

Abstract

The ophionine ichneumonid known as Hellwigiaobscura has been reared for the first time, from larvae of Horisme sp. (Lepidoptera: Geometridae) feeding on Clematisvitalba in The Netherlands. The cocoon and the parasitoid’s means of emergence are figured, as are some features of the adult. On a balance of morphological grounds, including some already discussed in the literature, it is proposed that “Hellwigia” obscura should be excluded from Hellwigia and instead be ascribed to the genus Heinrichiellastat. rev. as Heinrichiellaobscuracomb. n. Reasons for this change as well as for preferring this generic name to Protohellwigia Brues are given

Integrative taxonomy and analysis of species richness patterns of nocturnal Darwin wasps of the genus Enicospilus Stephens (Hymenoptera, Ichneumonidae, Ophioninae) in Japan

“…Darwin wasps are parasitoids of other holometabolous insects or spiders (very occasionally other arthropods or phytophagous) so they play an important role in terrestrial ecosystems as regulators of host insect populations (e.g., Townes 1969;Gauld 1991;Wahl 1993;Quicke 2015;Broad et al 2018). Ophioninae Shuckard are a species-rich subfamily of Darwin wasps, comprising 32 extant genera and more than 1,100 valid species worldwide (Yu et al 2016;Shimizu and Lima 2018;Shaw and Voogd 2019) and understood to be a monophyletic group within the 'higher ophioniformes', a clade of koinobiont endoparasitoids, mostly attacking Lepidoptera (e.g., Gauld 1985;Quicke et al 2009;Bennett et al 2019). Many members of the Ophioninae have morphological features associated with crepuscular and/or nocturnal behaviour (i.e., long antennae, large body, large ocelli, testaceous colour, etc.).…”

First records of the genus<i> Leptophion</i> Cameron (Hymenoptera: Ichneumonidae: Ophioninae) from Vietnam

“…Ophioninae Shuckard, 1840 is one of the largest ichneumonid subfamilies with more than 1,100 recognized species in 33 genera all over the world (Gauld & Mitchell, 1981;Yu et al, 2016;Shaw & Voogd, 2019). They are solitary koinobiont endoparasitoids of Lepidoptera larvae and have noctural behavior (Gauld & Mitchell, 1981;Broad & Shaw, 2016).…”

The Nepalese species of the genus Enicospilus Stephens, 1835 (Hymenoptera, Ichneumonidae, Ophioninae): a preliminary revision and identification key to species

“…The Ophioninae comprises 32 genera and over 1,100 species worldwide (e.g. Yu et al 2016;Shimizu and Lima 2018;Shaw and Voogd 2019). Many species of Ophioninae are considered to be crepuscular or nocturnal and usually have a testaceous body, very large ocelli (posterior ocellus close to or touching eye), and long antenna, with a few exceptions (e.g.…”
