Kaszabia

DIAGNOSIS: Males of Kaszabia are distinguished from Isoperla mainly on the presence of unique, dorsallydirected lateral processes on abdominal terga 3 and 4. Females can also be discriminated on a species-by-species basis from various Isoperla , as the subgenital plate is similar to some Isoperla . Nymphs are indistinguishable from Isoperla using typically diagnostic characters of Perlodidae such as lacinia and setation (Teslenko 2008).

DISTRIBUTION—Global: East Palearctic— Regional: AOB, POB*— Aimag: AR, DO*, KhE*, KhG, SE*, TO, UB*, ZA^.

DISCUSSION: This genus was originally described from the Mongolian species, Kaszabia nigricauda ( spinulosa ) (Raušer 1968). Recently, it was suggested that Kaszabia be moved to Isoperla based on nymphal and genitalic similarities (Zwick & Surenkhorloo 2005). In the following series of maps, species are grouped according to morphological similarity in order to highlight areas of sympatry between similar species. See habitus pictures ( Fig. 296, 298, 300) for depiction of morphological representations of each group.
