Kamimuria zwicki sp. n.

( Figs. 1-4 )

Material examined. Holotype ♂ and 3 ♂ paratypes from South Korea, Jirisan , Mamyang-gun , Songjeonli , Mansu-sa, 400 m, 27 June-27 July 2004, Tripotin Rec (Holotype, 1 paratype, INHS; 2 paratypes, BPS). Adult habitus. General color yellow brown. Head pale with darker U-shaped marking connecting ocelli; posterolateral margins of head, narrow line behind ocelli and lappets dusky ( Fig. 1 ). Antennae pale brown, palpi pale. Pronotum brown with slightly darker areas scattered on disc. Wing membrane yellowish, veins pale brown. Femora and tibiae pale brown but tibiae slightly darker at knee; basal tarsal segments brown, apical segment pale except for tip of segment. Cerci pale.

Male. Forewing length 20-22 mm. Abdominal terga 8-9 with median patches of sensilla basiconica larger on 9. Projecting portion of hemiterga about twice as long as basal width; posteromesal margins of hemiterga with linear patch of sensilla basiconica ( Fig. 2 ). Hair brushes on abdominal sterna 5-7. Aedeagal apex bearing a prominent, ventral pair of large pincer shaped sclerites and two short median rows of 2-4 small tooth-like spines; proximal end of spine rows usually with a few minute spinules centered between spines ( Figs. 3-4 ). Median section of aedeagal tube armed with large patch of minute spinules; patch encircles ventrolateral area but is interrupted dorsally by a median longitudinal bare area.

Female. Unknown.

Larva. Unknown.

Etymology. The patronym honors our friend and colleague, Professor Dr. Peter Zwick, in recognition of his early studies of the Korean stonefly fauna ( Zwick 1973a, 1973b), and in recognition of his systematic resurrection of genus Kamimuria ( Zwick 1977)

Diagnosis and Discussion. Kamimuria zwicki is related to K. lyubaretzi Teslenko and K. sparsula Du , two recently described species in which the apex of the aedeagus bears prominent sclerites ( Teslenko 2006; Du et al. 2001). The former species from the Russian Far East bears a single pair of long slender spines and several (ca. 7) smaller spines arranged in a proximal circumlinear row near the bases of the large spines. The latter species from Tianmu Mountain, Zhejiang Province, China bears a pair of enlarged spines on both the dorsal and ventral margins near the aedeagal apex.

Kamimuria males from Thailand and Vietnam (Sivec & Stark unpublished), Japan (Uchida & Isobe 1991; Sivec et al. 1988), Bhutan ( Zwick 1977) and other areas where there is sufficient documentation, are known to have simple aedeagal armature usually consisting of patches of small spines. The discovery of species with complex armature from East Asia is an interesting development.
