( Fig. 35 )

Material examined. RUSSIA: Fൺඋ Eൺඌඍ: khr. Mal. Khingan [= ridge Lesser Khingan], r [= river] Dichun, 13.vii.1979, 1 J, A. Shatalkin leg. ( SMOC, whole specimen in pinned plastic tube in glycerine, genit. prep.). Note. the locality lies in the Jewish Autonomous Region, ca 13 km SE Radde selo (= larger village), near the confluence of the Dichun and Amur rivers, coordinates 48°31ʹ15ʺN 130°44ʹ10ʺE (A. Shatalkin, personal communication, 2021).

Remarks. In contrast to congeners ( F. albimana and F. buccata Roháček & Barber, 2004 ), this species has the fore leg uniformly yellow, with only the apical tarsal segment (partly) darkened brown but the hind femur ( Fig. 35 ) with pale brown to brown subapical annulus (knee yellow). Setae in posteroventral row on male f 3 longer than other setosity, only 3 or 4 in distal half somewhat shortened and slightly (in contrast to those of F. albimana ) thickened.

Biology. Unknown owing to its rarity. The holotype male was collected in August (RඈIJගඹൾκ 2009), the specimen recorded here in July.

Distribution. The species was known only from southern Primor’e (40 km SE Ussuriysk) in the Far East of Russia. The above male (second known specimen) originates from a locality in the Jewish Autonomous Region, lying some 560 km further north.
