Sivec, Ignac & Stark, Bill P., 2008, New Species Of Kamimuria Klapálek (Plecoptera: Perlidae) From Thailand And Vietnam, With Notes On Chinese Species, Illiesia 4 (12), pp. 110-138 : 116-117

Kamimuria curriei sp. n.

( Figs. 21-27 , 74-75)

Material examined. Holotype ♂ and 1 ♂, 2 ♀ paratypes from Vietnam, Lao Cai, Sapa, large waterfall on road from Sapa to Lai Chau, 8 May 1995, ROM 956022, D. Currie, B. Hubley, J. Swann ( ROM). Additional paratype: Vietnam: Lao Cai, Sapa , Muong Hoa Ho River, 5-12 May 1995, ROM 956007, D. Currie, B. Hubley, J. Swann, 1 ♀ ( IEBR) .

Adult habitus. General color brown patterned with dark brown. Head dusky brown with darker areas between ocelli and forward of M-line ( Fig. 21 ); M-line and anterior margin of head pale; antennal base brown, second segment darker, flagellum brown. Pronotum brown with darker rugosities on disk; median suture, anterior and posterior margins of disk and lateral downturned edges dark brown. Wing membrane pale brown, veins brown. Femora pale basally, becoming dusky near apex ( Fig. 24 ); narrow apical band black; ventral base of tibiae with an oblique dark band, most of tibiae brown; tarsi brown.

Male. Forewing length 21-22 mm. Hemitergal lobes short, wide at apex and bearing a basal callus covered with sensilla basiconica ( Figs. 22-23 ); outer tips of hemiterga with 1 or 2 sensilla giving an acute spine-like appearance to apices. Tergum 9 with a median low knob covered with sensilla basiconica; tergum 8 with only 4-5 small sensilla basiconica in a sparse mesal patch. Aedeagal sac membranous except for ventral base; apex of sac directed ventrally giving a foot shaped structure covered along apical half of ventral surface and mid-laterally with fine to moderate sized spines ( Figs. 26-27 ); largest spines occur laterally and ventrally near apex and these transition into finer, long spines below the small membranous lobes located on sac dorsum. Dorsal and ventral third of sac without armature.

Female. Forewing length 26-28 mm. Subgenital plate a short triangular projection with shallow, wide notch; apex of plate extends over basal third of sternum 9 ( Fig. 25 ).

Egg. Outline oval to spherical with short, narrow, stalked collar; rim of collar flanged and irregularly incised. Chorion covered throughout, except for area surrounding collar, with fine pits of rather uniform size ( Figs. 74-75 ).

Larva. Unknown.

Etymology. The patronym honors Dr. Douglas Currie, one of the collectors of the type series of this species and other material used in this study.

Diagnosis. Males of this species have similar hemiterga to K. obtusa and K. klapaleki but differ significantly from both in aedeagal features (compare Figs. 27 , 37 and 97). The female subgenital plates for K. curriei and K. obtusa ( Figs. 25 , 36) are also distinct.
