SYNONYMY

Arcynopteryx sajanensis Zapekina-Dulkeit, 1957

TYPE LOCALITY: USSR: Mana river tributaries .

DIAGNOSIS: Both males and females are macropterous ( Fig. 257). The male hemitergal lobes are short and blunt ( Fig. 258), but not quite as stout as those of Skwala pusilla ( Fig. 292). The female subgenital plate has a wide median notch, much broader than other Arcynopteryx ( Fig. 249, 254). In addition, the lobes of the female plate are pointed and their medial surfaces are parallel sided ( Fig. 259). The nymph is unknown.

DISTRIBUTION—Global: Altaian— Regional: AOB— Aimag: KhG.

DISCUSSION: Previous to our survey, this species was recorded from Mongolia only as female specimens (Zhiltzova & Varykhanova 1984). Our records add 1 male specimen along with 2 females from north of Khovsgol lake ( Fig. 260), confirming the validity of the historical record. Specimens from Mongolia may be erroneously identified as A. amurensis (Zhiltsova and Levanidova, 1978) as was the case with the historical specimens we examined .
