( Figs. 2, 4 )

Type material: Holotype ɗ, CHINA: Pikeng, Mt. Wuyi (26.54 ºN 116.42 ºE), Fujian Province, 600 m, 27.v.2004, YU Haili, slide no. WXP03385. Paratype 1 ɗ, same data as holotype.

Diagnosis. Scotiophyes subtriangulata is similar to S. faeculosa , but can be separated by the following features: the basal blotch and the median fascia are distinct; the uncus is subtriangular, narrowed gradually apically; the sacculus is smooth ventrally near the base; the arms of the gnathos are thick and short; and the aedeagus is slender. In S. faeculosa , the basal blotch and the median fascia are indistinct; the uncus is slender distally; the sacculus has two processed ventrally; the arms of the gnathos are slender; and the aedeagus is short and thick.

Description. Adult ( Fig. 2 ): Head: Labial palpus slender, white, length ca. 2/3 times diameter of compound eye, outer side of second and third segments yellow. Frons whitish. Vertex with erect and rough yellowish scales. Antenna thick, ciliate, yellowish brown. Thorax: Grayish brown. Tegula pale dark basally, gray distally. Legs yellowish white, outer side of foreleg with gray scales; midleg and hindleg pale gray. Forewing length 10.0– 11.5 mm. Forewing oblong, costal margin distinctly convex from base to middle, then straight, expanded apically; apex short, sub-square; termen almost straight; ground color fulvous, with scattered rust brown scales; pattern elements dark brown: narrow basal blotch; median fascia extending from costa before middle to dorsum, narrow medially; subapical blotch very large, extending to apex and tornus, broad anteriorly, narrow posteriorly; fringe dark brown at apex, the remainder concolorous with ground color. Hind wing dark gray, fringe pale gray. Abdomen: Male genitalia ( Fig. 4 ) with tegumen broad, short, wider than long. Uncus large, longer than tegumen, subtriangular, dilated and thickened basally, with a group of sockets, narrowed gradually towards apex, pointed apically and with a few bristles. Socius fused with gnathos, ca. half as long as gnathos. Arms of gnathos short, strong, distinctly bifurcate near middle, strongly sclerotized distally. Transtilla bandlike, long, narrow, sinuate. Valva broad, narrowed distally. Costa short, reaching to ca. middle of valva. Sacculus broad, distal portion expanded outwardly. Aedeagus straight, as long as width of tegumen, weakly sclerotized; vesica without cornuti (possibly deciduous); juxta broad, expanded laterally; coecum penis short; caulis small. Female genitalia unknown.

Etymology. The specific name is derived from the Latin prefix sub - and triangulatus (triangular), based on the shape of the uncus.
