Oedaspis Loew 1862

Genus Oedaspis Loew Oedaspis is characterized by a usually very short proboscis, posterior orbital setae usually stubby white and 2–5 frontal setae, frequently variable even within the same species and often differing either side. Variation in the number of setae also occurs on the thorax and presutural dorsocentral setae are occasionally present. The scutellum is shiny or subshiny and often swollen, wings with 2 distinct setae on Sc break, cell c broadly hyaline medially without a dark spot or band, and a distinct band or band like pattern resembling λ or H pattern in middle at least in females. Abdomen subshining brownish or shiny black, with microtrichia. Aculeus often with serrations and glans of phallus with elongated flap-like vesica, rounded at apex. Keys to species of genus Oedaspis from Asia 1.

O. schachti Korneyev - Scutellum convex, not flat dorsally; bands not covering wing entirely and hyaline indentations as or almost as wide as bands. ................................................................................................... 2 2. Scutellum shiny black and strongly swollen (South-east of European Russia, Tajikistan, Iran and Afghanistan).................................................................................................. O. ragdai Hering - Scutellum yellowish with black spots around scutellar setae and not strongly swollen............................... 3 3. Presutural dorsocentral setae normally absent, if present than only on one side and without black annular base........... 4 - Presutural dorsocentral setae always present and with black annular base......................................... 7 4. Scutum yellowish with 4 vittae forming a lyrate-like pattern, less dense microtrichia and often black spots at base of prescutellar acrostichal setae (Kazakhstan; Mongolia; Russia)............................................. O. dichotoma Loew - Scutum greyish or darker with or without orange area on lateral sides and just above scutellum, with dense microtrichia and often without black spots at base of prescutellar acrostichal setae............................................... 5 5. Scutum entirely dark with presutural dorsocentral seta on one side and without black annular base (China: Hubei)............................................................................................. .. O. chinensis Bezzi - Scutum dark with yellowish orange area on margins and presutural dorsocentral seta always absent.................... 6 6. Scutellum with 3 spots, one larger at the base of apical scutellar setae, cell r4+5 with narrow apical band (China: Jiangsu)...................................................................................... O. meissneri Hering - Scutellum with 4 black spots, at base of each scutellar seta and mostly equal-sized, cell r4+5 with broader apical band (India: Himachal Pradesh)................................................... O. nauniensis Maneesh & Hancock, sp.n. 7.
