SYNONYMY

Pictetiella asiatica Zwick & Levanidova, 1971

TYPE LOCALITY: Russia: Kamchatka .

DIAGNOSIS: Adult coloration golden brown in preservation, with distinct pale markings on the clypeus, in the interocellar region, and along a pronotal median stripe ( Fig. 283). The tenth tergum of the male is divided ( Fig. 284), but lacks the distinct hemitergal processes found in Arcynopteryx ( Fig. 248) and Skwala ( Fig. 292). Rather, the hemitergal processes are flat and broad, primarily demarcated by a spinulose patch ( Fig. 284). The male paraprocts and epiproct are nearly inconspicuous externally ( Fig. 284), though the narrow, straight epiproct often protrudes and points posteriorly. Females have a large, broadly rounded plate that is incised basally and expanded posteriorly as two large lobes with a shallow notch. The plate extends completely over sternum 9, whereas all other Perlodinae have much shorter plates ( Fig. 293) though some Isoperlinae have long, more triangular plates ( Fig. 329, 353). Nymph head coloration generally dark but with a pale diamond in the interocellar region( Fig. 286), similar to Filchneria mongolica . The ventral side of nymph head has long submental gills ( Fig. 244).

DISTRIBUTION—Global: East Palearctic— Regional: AOB^— Aimag: KhG^.

DISCUSSION: This species is a new record for Mongolia which seems to be restricted to the Khovsgol lake region. Since there is only one documented occurrence, we were unable to generate a map of the predicted range.
