Paragnetina flavotincta (McLachlan, 1872)

SYNONYMY

Perla flavotincta McLachlan, 1872

Paragnetina ocellata Klapálek, 1921

Paragnetina flavotincta Illies, 1966

TYPE LOCALITY: USSR: Pokrofka , Amur .

DIAGNOSIS: Adults have a distinct dark interocellar area ( Fig. 224). The male hemitergal processes are shorter than those of Agnetina ( Fig. 213) and slightly longer than Kamimuria exilis ( Fig. 220). Where the hemiterga bend to approximately form a 90 degree angle, there is a protruding knob ( Fig. 225). The female subgenital plate is strongly bilobed with a deep U-shaped notch ( Fig. 226). The nymph of Paragnetina flavotincta has similar pigmentation to K. exilis but has distinctive high contrast patterning on the head and pronotum ( Fig. 227). In particular, the head has a pale oval intruding the ocellar region and the protnoum has broad, pale rugosites medially. The nymph lacks anal gills ( Fig. 197), which Agnetina species possess.

DISTRIBUTION—Global: East Palearctic— Regional: AOB, IDB*- Aimag: BU^, KhD*, KhG, SE, TO^.

DISCUSSION: In our collections, P. flavotincta was found in larger low-gradient rivers. This species was first documented from Mongolia by Zhiltzova (1975) and is also documented throughout the east Paleartcic, particularly in the Amur Basin and Korea (Levanidova & Zhiltzova 1979).
