Colour. Antenna blackish brown; head yellow; stemmaticum black; teeth black; palpi yellow; mesosoma, metasoma, all legs yellow but claws brownish yellow. Fore and hind wings yellow on basal half, dark brown on apical half; pterostigma black; veins dark brown.
Variation. Females: body length 10.0-11.0 mm; fore wing 7.8-8.2 mm; antenna with 50-53 segments; inner side of fore tibia with 3-4 thick spines; scutellar sulcus with 3-4 carinae.
Male. Unknown.
Etymology. “flavus” (Latin for “yellow”); “corpus” (Latin for “body”), because of the entirely yellow body.
Remarks. Zombrus flavicorpus sp. n. can be separated from Z. striolatus by the following characters: a) In lateral view, eye 1.43 × as long as wide (1.25 × in Z. striolatus); b) OOL 3.2 × as long as POL (1.25 × in Z. striolatus); and c) basal half of fore and basal two third of hind wings yellow (basal third of fore wing, basal half of hind wing yellow in Z. striolatus).
