(Figs. 1, 1 a, 9, 9a, 9b)
Type material. HOLOTYPE: 3, Papua New Guinea, Morobe, Mount Kaindi, 2360 m, 3 x 1992, V.O. Becker, Coll. Becker, PNG-1605, gen. slide no. CIS-5783/Park. PARATYPE: 1 3, same data as the holotype, gen. slide no. CIS-5764/Park. Types are deposited in the USNM.
Diagnosis. The new species is externally similar to Lecithocera barbifera Meyrick which was described from Java, Indonesia, but it is distinguished from the latter by its smaller size, the forewing slightly dilated posteriorly with uniformly scattered blackish scales, and the male genitalia with a single spinelike cornutus.
Description. Male. Forewing length, 6.0–8.5 mm. Head yellowish brown, with whitish erect scales laterally. Antenna with orange white, slender basal joint; flagellum orange white with brownish yellow annulations. Second segment of labial palpus thickened, orange white, speckled with blackish scales on outer surface, orange white on inner surface; 3rd segment strongly upturned, slightly longer than 2nd segment, orange white all around, with acute apex. Tegula and thorax yellowish brown on dorsal surface. Forewing ground color pale grayish, blackish scales uniformly scattered; apex obtuse; termen slightly concave beyond apex; venation with R1 arising before middle of cell; distance between R1-R2 about 3 times longer than that of R2-R3; R3 connate with R4+5 at base; R4 and R5 stalked for 3/4 length; R5 reaching termen; M1 remote from R4+5 at base; M2 nearly parallel to M3; M3 free; CuA1 and CuA2 stalked at basal 1/5 of CuA1; cell closed with weak cross vein. Hindwing slightly broader than forewing; costa nearly straight; apex acute; termen oblique, nearly straight; venation with Rs and M1 stalked for 1/3 length beyond end of cell; M2 near to M3 at base; M3 and CuA1 stalked for 1/3 length; cell partly closed. Hind tibia orange white, smoothly scaled. Female unknown.
Male genitalia (Figs. 9, 9a, 9b). Basal lobes of uncus ovate. Gnathos short, gently arched. Costal bar well developed, with acute angle medially. Valva broad at base; costa strongly concave in basal 1/3, then gently arched; apex rounded; ventral margin with prominent, broad median expansion, then strongly concave beyond; pectinate plate long, strongly bent beyond middle, combs nearly same length; sacculus narrow, terminated before lower corner of median expansion. Juxta shield-shaped; caudal margin slightly concave, without anterior process. Vinculum broad, with round apex. Aedeagus as long as valva, more or less stout, bent near 1/3; cornutus a single strong spine, shorter than 1/3 length of aedeagus. Eighth abdominal sternite short, concave medially on caudal margin; abdominal coremata absent.
Distribution. Papua New Guinea (Morobe).
Etymology. The species name is derived from the Latin singulus (= single, one), referring to a single spinelike cornutus.
