TYPE LOCALITY: Siberia : Chabarovskiy district, River Kur .

DIAGNOSIS: The head of adults is golden-brown in the interocellar region and has dark brown markings along the anterior margins of the head ( Fig. 202). The pronotum is darkwith pale rugosites medially ( Fig. 202). The male of A. brevipennis is brachypterous ( Fig. 202), whereas the female is macropterous. Both sexes of other Agnetina species are macropterous ( Fig. 207, 212). The male hemitergites are simple, gradually tapering to the apex and with only gentle curves in the dorsal and lateral aspects ( Fig. 203). The female subgenital plate is subtriangular and may be variably pointed or truncate ( Fig. 204). The nymph of this species most closely resembles A. extrema (Navás, 1912) ( Fig. 215), both species having an unpigmented region on the clypeus and dark pigmentation on the labrum. Conversely, A. cocandica has an isolated M mark on the clypeus and a pale labrum with only a thin dark line along the anterior margin ( Fig. 210). In A. brevipennis , the light area on the clypeus gradually widens from its origin above the ocelli to form a rough-edged triangle ( Fig. 205), whereas in A. extrema the light region is invaded by two dark arms.

DISTRIBUTION—Global: East Palearctic— Regional: AOB, IDB, POB*— Aimag: AR, BO, BR*, BU, DO*, GA*, KhD, KhE*, KhG^, OV, SE, TO*, UB*, ZA^.

DIAGNOSIS: According to Sivec et al. (2005), the dissected esophagus has major proventricular bands that are of uniform width in both A. brevipennis and A. extrema , unlike A. cocandica which are very narrow in the middle. This character was confirmed in a random sample of Mongolian nymphs. However, for Mongolian Agnetina species , external characters such as head pigmentation are typically sufficient for identification.
