Description

Adult (Fig. 1 A-C, E and F). Male. Head: Vertex of head densely clothed with brown hairs; ocelli absent; antennae less than 1/3 length of forewing, flagellum bipectinated. Thorax: notum covered with dark-brown scales. Wingspan 14 mm. Forewing dark-brown scale covered, generally without markings on upperside; 6.8 mm in length excluding fringe with termen distinctly formed; median cell 0.69 times as long as forewing; accessory cell absent; intercalary cell present; Sc and R1 terminating at 4/5 costa; R2 and R3 stalked at anterior part of the cell; R4 and R5 originating at corner of anterior part of cell to reach apex; M2 stalked at corner of intercalary cell; CuA1 and CuA2 parallel to tornus. Hindwing covered with greyish scales; 4.9 mm excluding fringe, with termen distinctly formed and gently curved; median cell 0.59 times as long as hindwing; Rs and M1 separated. Legs covered with dark brown scales. Abdomen: Male genitalia with tegumen wide, rounded; uncus formed as rectangular; saccus straight, slightly long and slender; apical part of ampulla gently arched with club shape, setae present, length of ampulla 0.45 times as long as length of valva dorsal margin; phallus curved, cornuti wide and long. In dorso-ventral aspect, uncus concave; gnathos absent; valva slightly narrow, apical part of valva presented with short setae; apical margin of harpe formed into three weakly-rounded laciniation; juxta absent; anellus well developed, pointed, 0.3 times as long as length of valva; phallus long. Larval case (Fig. 1 D). 9 mm in length. Larvae attach their tiny and slender branches on to the larval case of cylindrical shape.

Diagnosis

This species is similar to P. nigra Saigusa and Sugimoto, but can be distinguished by the much darker wings being blackish-brown and pectinations of the antennae elongate and about about same length from basal flagellomeres to flagellomere 9. Whereas in P. nigra , the wings are slightly lighter, being brownish-black and pectinations of antennae abruptly becoming longer to 7th flagellomere.

Etymology

The specific name is derived from the Latin cornu and cerva (= antler), referring to the antennae shape.

Distribution

Korea (new species).
