SYNONYMY

Dictyopteryx mongolica Klapálek, 1901

Filchneria mongolica Klapálek, 1908

TYPE LOCALITY: Mongolia: North-eastern region .

DIAGNOSIS: Tenth tergum of male is not divided and lacks hemitergal processes ( Fig. 274). The 8th to10th tergites have protruding spinule patches ( Fig. 274). The male lacks external genitalic features. The female subgenital plate is heart shaped ( Fig. 275), with a strong median notch forming broadly rounded lobes. Nymphs have a diamond-shaped, interocellar spot ( Fig. 276) that is closed posteriorly and lacinia with closely spaced apical teeth and relatively few short hairs on the inner edge ( Fig. 239).

DISTRIBUTION—Global: Central Asian— Regional: POB*— Aimag: DO*, TO*.

DISCUSSION: This species was originally described from Mongolia on one of the earliest known zoological expeditions (Klapálek 1901) in the country. It is known from the eastern region ( Fig. 277) where our team has not yet sampled. This species was recently collected from the Selenge River in Russia (Teslenko & Bazova 2009), and a male and female collected in 1966 were reported from 24 km SW of Ulan Bator (Hungarian Natural History Museum, Budapest) by Teslenko et al. (2010).The nymphs bear strong resemblance to Isoperla potanini ( Fig. 309) and Pictetiella asiatica ( Fig. 286) in terms of body size and head patterning, particularly the interocellar diamond. Filchneria mongolica can be separated from these two species based on lacinial characteristics explained in the genus level description.
