Paraleuctra

DIAGNOSIS: Paraleuctra adults are dark brown in color and very slender ( Fig. 135). The cercal segments of males are heavily modified, surrounding the simple short epiproct which is oriented perpendicular to the body ( Fig. 143). The female plate is bilobed and protrudes off the body ( Fig. 144). Nymph have palps subequal to the glossae ( Fig. 133), as opposed to Leuctra which has long palps. Nymphs lack short setae on the posterior margin of abdominal tergites ( Fig. 134) which Leuctra nymphs possess.

DISTRIBUTION—Global: Holarctic— Regional: AOB— Aimag: SE, TO.

DISCUSSION: The genus Paraleuctra is richer in the Nearctic than the Palearctic. It is interesting that this points to connections east across Beringia while the distribution of L. fusca , which is similar in placement and extent to P. zapekinae Zhiltzova, 1974 , is to the west, Europe. More collections from this range are warranted.
