Kiotina bifurcata sp. n.

(Figs. 1–4)

Material examined. Holotype ♂ (pinned, forewings missing) from China, Fujian Province, Kuatun, 2300 m, 27.4 ° N, 117.4 ° E, 1 April 1938, J. Klapperich (ZFMK).

Adult habitus. Apparently biocellate, anterior ocellus absent or obscure. Body color dark brown to black. Head and pronotum black. Ocelli widely spaced, nearer eyes than each other. Pronotum widest medially, bearing rugosities. Meso and meta nota dark, abdomen paler. Legs and antennae dark.

Male. Forewings missing, hind wing length 12 mm. Tergum 10 armed with a pair of forked, lateral spines and a subterminal pair of dark projections. Epiproct sclerite with well developed long, slender arms arising from a short base (Fig. 1). Paraprocts curved forward over tip of abdomen. Aedeagus incompletely everted but membranous and bearing a pair of lateral arm-like lobes (Figs. 3-4); apical area of aedeagus complexly lobed. Hammer oval and set near posterior margin of sternum 9 (Fig. 2).

Female. Unknown.

Larva. Unknown.

Etymology. The species name is based on the distinctive, forked lateral spines on tergum 10.

Diagnosis. This species is distinguished from known Kiotina by the bifurcate tergal spines and by the long, slender epiproct sclerite Y-arms. We have seen a similar specimen from Guangxi Province, China, but do not have sufficient data to determine its status.
