Kamimuria exilis (McLachlan, 1872)

SYNONYMY

Perla exilis McLachlan, 1872

Marthamea luteicauda Klapálek, 1921

Kamimuria exilis Sivec et al., 1981

TYPE LOCALITY: Siberia.

DIAGNOSIS: The head of adults has a U-shaped central dark mark connecting the ocelli and open posteriorly ( Fig. 219), as opposed to Paragnetina flavotincta (McLachlan, 1872) whose central mark covers the entire ocellar region ( Fig. 224). Male hemitergal processes ( Fig. 220) are much shorter than those of Agnetina ( Fig. 213) and Paragnetina ( Fig. 225). Hemitergal processes are not bent ( Fig. 220) like those of P. flavotincta ( Fig. 225), and have spines on the inner margin of the apex. The female subgenital plate is notched by a shallow triangle and the lobes are pointed ( Fig. 221). In contrast to P. flavotincta ( Fig. 226), the notch is much more shallow. The nymph of K. exilis has a subtle contrasting pattern of dark brown markings on a tan body. The nymph is readily distinguished from Agnetina by the absence of anal gills ( Fig. 197), but only distinguished from P. flavotincta ( Fig. 227) on the basis of coloration. Kamimuria exilis nymphs are darker overall and have small isolated pale regions on the head and pronotum ( Fig. 222), much smaller than the pale markings of P. flavotincta .

DISTRIBUTION—Global: East Palearctic- Regional: AOB, IDB*, POB*— Aimag: AR*, BO*, DO*, KhG^, TO*.

DISCUSSION: We have only collected females of K. exilis in Mongolia. All known historical specimens are also females (Zhiltzova 1975, 1979). We suggest additional collecting in the north and west to document males in order to confirm species identification, although the female is believed to be sufficiently distinct.
