A new species of Oomyzus Rondani (Hymenoptera, Eulophidae) reared from the pupae of Coccinella septempunctata (Coleoptera, Coccinellidae) in China

Abstract

Oomyzus spiraculus Song, Fei & Cao sp. nov. (Hymenoptera, Eulophidae) is described and illustrated as a gregarious larval-pupal endoparasitoid of Coccinella septempunctata L. (Coleoptera, Coccinellidae). Differentiation between O. spiraculus and its similar species is discussed and a key to differentiate the female and male of these species is provided. DNA barcodes of O. spiraculus and O. scaposus are analyzed and compared.

Interactions Among Native and Non-Native Predatory Coccinellidae Influence Biological Control and Biodiversity

“…septempunctata , but rarely attack H . axyridis ( Song 2017 ; Song et al 2017 , 2020 ). In Western Siberia, the phorid parasitoid P. fasciata parasitized 45% of C .…”

A new monotypic genus of the subfamily Tetrastichinae (Hymenoptera: Chalcidoidea: Eulophidae) from China

“…Some species are phytophagous, inquilines, or gall-formers (LaSalle, 1994). In China, 24 genera and 165 species of this subfamily are reported (Perkins, 1912;Timberlake, 1921;Miwa et al, 1935;Yoshimoto, 1970;Yang & Wei, 2003;Yang et al, 2003a,b;2005;Wu et al, 2001;Li, 2013;Li et al, 2014;Yang et al, 2014;Song et al,2014;Li et al, 2020;Song et al, 2020;Li, 2021).…”

A new species and three newly recorded species of Tetrastichinae (Hymenoptera, Eulophidae) from China

“…With more research on parasitic wasps, Chinese entomologists realized the importance of this faunal group: Liao et al (1984) reported 201 economically important insect species of China including eight species of Tetrastichinae; Yang (1996) systematically investigated parasitic wasps on bark beetles from China and reported 141 species including 16 species of Tetrastichinae; Zhu and Huang (2001) investigated Eulophidae from Zhejiang province and reported 12 species of Tetrastichinae; Zhu and Huang (2002) investigated Eulophidae from Guangxi province and reported 23 species of Tetrastichinae; Zhang et al (2007) investigated Eulophidae from south Gansu and Qinlin Mountains and reported 14 species of Tetrastichinae; Yang et al (2015) systematically investigated parasitic wasps on forest defoliators, reporting 115 species including 20 species belonging to four genera of Tetrastichinae. Subsequently, there are many more reports of new species and records of Tetrastichinae (Yang 1989;Sheng andWang 1992, 1993;Sheng 1995;Sheng and Zhao 1995;Sheng and Zhu 1998;Yang and Wei 2003;Jiao et al 2006;Zhang et al 2009;Wu et al 2009;Li et al 2014;Yang et al 2014;Feng et al 2016;Li et al 2016;Song et al 2017;Li 2020, 2021;Song et al 2020;Guo et al 2022;Ning et al 2022). In terms of Tetrastichinae species richness, there is an obvious imbalance among provinces of China.…”
