Abstract:

Euphorinae is one of the largest subfamilies of Braconidae with more than 1,270 described species worldwide (Yu et al., 2016). In India, as of now, a total of more than 60 species have been described under 15 different genera. The genus Streblocera Westwood is one of the unique genera among the euphorines with female specimens having raptorial like antennae and long scapes. Members of this genus are known to be koinobiont endoparasitoids of adult chrysomelid beetles with more than 120 valid species present worldwide under five sub genera Asiastreblocera, Cosmophoridia, Eutanycerus, Villocera, and Streblocera (Li et al. 2021). Streblocera is still an understudied group in many parts of India with only ten species recorded under the subgenus Eutanycerus until now. Among them, nine species have been recorded from Uttar Pradesh and Madhya Pradesh States (Shamim, 2013) and one species has been reported from Tamil Nadu State (Gupta et al., 2022). The subgenus Asiastreblocera can be differentiated from other subgenera by having a face with an acute horn and fifth metaso­mal sternite with a pair of acute teeth (Chen and van Achterberg, 1997). A total of six species under the subgenus Asiastreblocera are reported from the Oriental region (China, Korea, Taiwan, and Thailand). In the present study, we report the occurrence of the subgenus Asiastreblocera for the first time in India, along with a list of known species occurring in India.
