Chinoperla View in CoL yi sp. n.

( Figs. 37-39 View Figs )

Material examined. Holotype ♂ from Lao Cai, Vietnam, large waterfall on road from Sapa to Lai Chau, 8 May 1995, D. Currie, B. Hubley, J. Swann, ROM 956022 ( ROM) . Paratype: Vietnam: Lao Cai, ca. 12 km on road from Sapa to Lai Chau, 1950 m, 1-12 May 1999, B. Hubley, ROM 992011, 1♂ ( ROM) .

Adult habitus. Biocellate. Head with dark brown pigment over ocelli and central frons extending to pale M-line; forward of M-line, a bell shaped dark area covers central frons; lappets and mesal occiput dusky brown ( Fig. 37 View Figs ). Pronotum pale brown with darker rugosities on disk; anterior and posterior margins with narrow dark brown band. Wings tinted with pale brown; veins dark brown except for pale costal area; Sc vein reduced, obscure except at base. Legs pale brown but darker at apex of femora and at base and apex of tibia.

Male. Forewing length 10 mm. Tergum 8 with a slightly produced, lightly sclerotized median lobe sparsely clothed with short setae. Dark median process of tergum 9 slightly longer than wide and broadly U-shaped on posterior margin ( Fig. 38 View Figs ). Finger shaped hemitergal processes about twice as long as basal width. Aedeagal tube damaged and poorly sclerotized, bearing a lateral pair of setal patches near base ( Fig. 39 View Figs ); sac not fully everted but with three spinous lobes; median lobe bearing a sclerotized terminal tooth shaped spine, dorsolateral lobes completely covered with small spines.

Female. Unknown.

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, honors the Yi people of the China-Vietnam border region near the type locality.

Diagnosis. Males of this species have a single tooth shaped aedeagal spine which is unlike the long slender spines found in C. unidentata and related species.
