A new genus and species of Collyriinae (Hymenoptera, Ichneumonidae)

Abstract

An enigmatic taxon collected in China is described as Bicurta sinica gen. n., sp. n. The unique specimen proved difficult to place to subfamily but has features in common with Collyria, until recently the sole valid genus of the small Palaearctic subfamily, Collyriinae. A morphological phylogenetic analysis of the pimpliformes group of subfamilies confirms the placement of this genus in the Collyriinae, which is here redefined.

A new species of Bicurta Sheng et al. from China (Hymenoptera, Ichneumonidae, Collyriinae), a parasitoid of Stenocephus fraxini Wei (Hymenoptera, Cephidae)

“…Type species. Bicurta sinica Sheng et al, 2012. Diagnosis. This genus is distinguished from Collyria by the epicnemial carina indistinct because of sculpture on the mesopleuron; ovipositor straight and smooth ( Fig.…”

“…This genus is distinguished from Collyria by the epicnemial carina indistinct because of sculpture on the mesopleuron; ovipositor straight and smooth ( Fig. 12), lacking teeth on the ventral valve; and the fore and mid tarsal claws each having an acutely lobed tooth (Figs 10,24) (Sheng et al 2012), while in the other two other collyriine genera, Aubertiella and Collyria, fore and mid tarsal claws with a median tooth, rather than a lobe.…”

“…Collyriinae is small subfamily of Ichneumonidae, including only three genera (Aubertiella Kuslitzky & Kasparyan, Bicurta Sheng et al, and Collyria Schiødte) with 11 described species, all distributed in the Palaearctic region (Gürbüz and Kolarov 2006;Wahl et al 2007;Kuslitzky and Kasparyan 2011;Sheng et al 2012;Yu et al 2016;Broad et al 2018), although with Bicurta sinica Sheng et al found in both the Palaearctic and Oriental regions (Sheng et al 2012(Sheng et al , 2013Shang et al 2016). The systematics of this subfamily, based on morphological characters, were discussed by Sheng et al (2012).…”

“…The genus Bicurta is monotypic, with only the type species B. sinica described from Jiangxi Province of China (Sheng et al 2012). Shang et al (2016) reported a male specimen of B. sinica from Liaoning Province in Northeast China.…”

A new genus and species of Anomaloninae (Hymenoptera, Ichneumonidae) from China

“…New discoveries have been reported (Sheng and Sun 2009;Sheng and Sun 2010a, b;Sheng and Broad 2011;Sheng and Sun 2011;Sheng et al 2012). Large numbers of anomalonines have been collected there and will be reported successively.…”
