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

Abstract

New genus Zhijilingia Xu, Liu et He, gen. n. (type species: Zhijilingia tettigonia Xu, Liu et He, sp. n.) is described from Sichuan, South China. This new genus can be distinguished from other genera of Tetrastichinae by following characters: antenna with 3 anelli and 4 funicular segments, only one clava segment, all funicular segments slender and longer than broad, funicular segments almost same in length, mesoscutum without a median line, propodeum with a distinct median carina, the whole rim of propodeal spiracle exposed, postmarginal vein absent. The new species probably parasitize eggs of the katydids Prohimerta dispar (Bey-Bienko, 1951) (Orthoptera: Tettigoniidae).
