A Taxonomic Study On The Subfamily Blacinae (Hymenoptera: Braconidae) From China

Blacinae Foerster is one of the smallest subfamilies of family Braconidae with 215 described species in the world. Many species of Blacinae are endoparasitoids of many families of Coleoptera larvae, such as Staphylinidae, Nitidulidae, Cryptophagidae, Scolytidae, Anobiidae, Curculionidae, Melyridae and Cerambycidae. A few species endoparasitize Diptera larvae, for example, Chloropidae and Cecidomyidae. In addition, Dyscoletes Haliday parasitizes Boreidae (Mecoptera) and Xyeloblacus van Achterberg parasitizes Xyelidae (Hymenoptera) larvae.In the taxonomic part,63 species of three genera in two tribes from China are recognized and described with illustrations based on about 1500 specimens, of which 38 species are new to science, and 25 species are recorded from China for the first time. Information on general characters, distribution and hosts are provided for each tribe and genus. Keys to tribes, genera, subgenera and species are also provided. In addition,11 species previously known from China are listed, but no specimens were available for this study.Types are all deposited in the Parasitic Hymenoptera Collection of Zhejiang University. The new and newly recorded taxa are listed as follows:New record of genera for China:Blacometeorus Tobias,1976; Xyeloblacus van Achterberg,1997.New record of subgenera for China:Blacus Hees,1818; Contochorus van Achterberg,1976; Hysterobolus Viereck,1913.New records of species for China:Blacus (Blacus) exilis (Nees,1812); Blacus (Blacus) filicornis Haeselbarth,1973; Blacus(Blacus) forticornis Haeselbarth,1973; Blacus (Blacus) leptostigma Ruthe,1861; Blacus (Blacus) paganus Haliday,1835; Blacus (Blacus) pappianus Haeselbarth,1973; Blacus (Blacus) radialis Haeselbarth, 1973; Blacus (Blacus) tobiae Haeselbarth,1973; Blacus (Ganychorus) hadrolophus van Achterberg,1988; Blacus (Ganychorus) kangauzi Belokobylskij,1995; Blacus (Ganychorus)pisinnus van Achterberg,1988; Blacus (Ganychorus) ruficornis (Nees, 1812); Blacus (Ganychorus) sutchaicus Belokobylskij,1995; Blacus (Ganychorus) tuberculifer van Achterberg,1988; Blacus (Hysterobolus) chabarovi Belokobylskij, 1995; Blacus (Hysterobolus) fuscitibialis van Achterberg,1988; Blacus (Hysterobolus) mamillanus Ruthe,1861; Blacus (Hysterobolus) robustus Haeselbarth,.1973; Blacus (Tarpheion) albiventris van Achterberg,1988; Blacus (Tarpheion) antennalis van Achterberg,1988; Blacus (Tarpheion) apicalis van Achterberg,1976; Blacus (Tarpheion) bicolor van Achterberg,1988; Blacus (Tarpheion) fuscinervis van Achterberg,1988; Blacus (Tarpheion) javensis van Achterberg,1976; Blacus (Tarpheion) soror van Achterberg,1988.New species:Blacometeorus sinicus sp. nov.; Blacus (Blacus) flaviabdominus sp. nov.; Blacus (Blacus) flavimaculus sp. nov.; Blacus (Blacus) laevifacialis sp. nov.; Blacus (Blacus) longicornis sp. nov.; Blacus (Blacus)parahumilis sp. nov.; Blacus (Blacus) qinlingensis sp. nov.; Blacus (Blacus) rufiabdominus sp. nov.; Blacus (Blacus) rugifacialis sp. nov.; Blacus (Blacus) sichuanensis sp. nov.; Blacus (Blacus) tianmushanensis sp. nov.; Blacus (Blacus) xizangensis sp. nov.; Blacus (Contochorus) cephalus sp. nov.; Blacus (Contochorus) thoracicus sp. nov.; Blacus (Contochorus) jianfengensis sp. nov.; Blacus (Ganychorus) emeiensis sp. nov:; Blacus (Ganychorus) flavidus sp. nov.; Blacus (Ganychorus) glabicephalus sp.nov., Blacus (Ganychorus) hadricornis sp. nov.; Blacus (Ganychorus) huangi sp. nov.; Blacus (Ganychorus) liupanshanensis sp. nov.; Blacus (Ganychorus) longiabdominus sp. nov.; Blacus (Ganychorus) paucicornis sp. nov.; Blacus (Ganychorus)paulioculus sp. nov.; Blacus (Ganychorus) ruficephalus sp. nov.; Blacus (Ganychorus) scutellus sp. nov.; Blacus (Ganychorus) wolongensis sp. nov.; Blacus (Hysterobolus) hei sp. nov.; Blacus (Hysterobolus) nigricans sp. nov.; Blacus (Hysterobolus) rufithorax sp. nov.; Blacus (Hysterobolus) rutilus sp. nov.; Blacus (Leioblacus) henanensis Chai & Chen, sp. nov.; Blacus (Tarpheion) baoshanensis sp. nov.; Blacus (Tarpheion) guizhouensis sp. nov.; Blacus (Tarpheion) tani sp. nov.; Blacus (Tarpheion) wuyishanensis sp. nov.; Blacus (Tarpheion) minor sp. nov.; Xyeloblacus longithecus sp. nov.
