Mesocapnia

DIAGNOSIS: The adults of this genus are generally dark brown to black in color ( Fig. 65), with limited golden brown rugosites on the head and pronotum. The male epiproct ( Fig. 68) is more slender than in Capnia , but wider than in Isocapnia . The epiproct is often variable in width from the dorsal view ( Fig. 72, 77) and usually gradually tapers to a narrow pointed apex. The subgenital plates of females are simple, ovoid structures ( Fig. 69) and lack the striking sclerotization patterns seen in Isocapnia . Nymphs are indeterminable to genus and cannot be consistently seperated from Capnia .

DISTRIBUTION—Global: Holarctic- Regional: AOB, IDB— Aimag: AR, BO, KhG, TO, UB*, UV*, ZA^.

DISCUSSION: The majority of specimens we collected were from elevations greater than 2000 msl. Some taxonomists debate the validity of this genus and suggest it be subsumed into Capnia (Zhiltzova 2003) .
