SYNONYMY

Paraleuctra zapekinae Zhiltzova, 1974

TYPE LOCALITY: Russia .

DIAGNOSIS: Overall, P. zapekinae adults are dark brown and slender ( Fig. 141). Cercal segments of the male are heavily modified, into upper and lower prongs that surround the epiproct and appear to interlock. The epiproct is a relatively simple short appendage that tapers slightly at the apex ( Fig. 142). When viewed laterally, the epiproct is perpendicular to the body ( Fig. 143). The female subgenital plate has distinctive black markings at the base and on the medial surfaces of the posterior lobes ( Fig. 144). Unlike Leuctra fusca , the female plate does not have an additional central shallow lobe ( Fig. 139), though the two posterior lobes are still clearly divided. Nymphal palps are subequal to the labium ( Fig. 133), as opposed to L. fusca which has long palps ( Fig. 131).

DISTRIBUTION—Global: East Palaearctic— Regional: AOB— Aimag: SE, TO.

DISCUSSION: Paraleuctra zapekinae was only recently recorded from Mongolia (Purevdorj, Muehlenberg & Slowik 2003), but is also known from areas in Russia immediately north of Mongolia (Levanidova & Zhiltzova 1979). Levanidova and Zhiltzova (1979) report a March flight period, which may be why collections in Mongolia during the summer have been sparse.
