The discovery of the rare genus Epimicta Foerster (Hymenoptera: Braconidae) in China, with a description of a new species

摘要

Epimicta sulciscutum sp. nov. from Heilongjiang (North China) is described and illustrated. A key to species of the genus is provided.Epimicta Foerster, 1862, is a small genus in Dacnusini with four described species from the Palearctic and Oriental region. One of the main diagnostic characters is the presence of striate sculpture on the second tergite and often on basal part of thirdtergite (Belokobylskij 2005). For a long period, this genus was known from only one species, E. marginalis (Haliday) which was recorded in West and East Palaearctic regions (Shenefelt 1974; Tobias 1986, 1998). Another Palaearctic species, Synelix rossica(Telenga), was originally placed in Epimicta but was removed to Synelix Foerster by Tobias (1986). The second species of this genus, E. longicaudalis Tobias, was described from Far East of Russia (Tobias 1998). The other two species in this genus, E. griffithsi Wharton and E. konzaensis Kula, were both described from the Nearctic region (Wharton 1994; Kula 2005).
