Description
Small chalcidoid riders , characterized by the following features: brown insects; some parts of the antennae (pedicel), chest (scutellum) and abdomen (middle tergites) are yellow; the ratio of antenna meters (F1 = 1) - 2.5: 1.1: 1: 1.5: 1.6: 1.4: 1.4: 1.3: 3.4; the ratio of the length of the ovipositor to the length of the anterior tibia is 3.3. Body length about 1 mm. The antennae are filiform. According to the number of antenna segments, sexual dimorphism is observed: the flagellum of females is 6-segmented (antennae 9-segmented) and in males, flagellum 11-segmented (antennae 13-segmented). The paws consist of 4 segments. Four membranous wings (posterior pair less than anterior) with fully reduced venation. The abdomen is stalked. Presumably, like other species, a kind of endoparasite on insect eggs. The species was first described in 1998, and its valid status was confirmed in 2015 during a world audit of the genus conducted by the Russian-American hymenopterologist Sergei Vladimirovich Tryapitsin (Entomology Research Museum, Department of Entomology, University of California , Riverside , California , USA ) [1 ] [2] [3] .
