- Pectinimura areola Park, sp. nov. (Figs. 2, 2 a, 10 a, 10 b) Type material. HOLOTYPE: 3, Papua New Guinea, Morobe, Wau, 1200 m, 8–14 xii 1976, G.P. Hevel & R.E. Dietz, Mercury vapor light, gen. slide no. CIS- 5712 /Park. The holotype is deposited in the USNM Diagnosis. The species is distinguished from congeners by the shorter 3 rd segment of labial palpus and the pale orange ground color of the forewing. The male genitalia are more or less similar to P. singularis sp. nov., but this new species has much shorter, nearly straight row of pectinate plate on valva, and has no spinelike cornutus in the aedeagus. Description. Male. Forewing length, 5.5–6.0 mm. Head brownish yellow to yellowish brown dorsolaterally. Antenna with dark brown, slender basal joint; flagellum dark brown in basal 1⁄4, then orange white. Second segment of labial palpus thickened, dark brown on outer surface, orange white on inner surface; 3 rd segment weakly upturned, as long as 2 nd segment, dark brownish all around, with acute apex. Tegula and thorax brownish yellow to yellowish brown on dorsal surface. Forewing ground color pale orange, brownish scales irregularly scattered; post median fascia yellowish brown, well-developed from costa to inner margin, broadened near both ends, concave on outer margin; terminal fascia broadly developed along termen, brownish yellow; costa nearly straight beyond basal 1 / 4, with dark brown fascia along margin for 1⁄4 length; apex obtuse; termen slightly sinuate; fringe concolorous with ground color, brownish near tornus; venation with R 1 arising before middle of cell; distance between R 1 -R 2 about 3 times than that of R 2 -R 3; R 3 free, close to R 4 + 5 at base; R 4 and R 5 stalked for 3 / 5 length; R 5 reaching termen; M 1 remote from R 4 + 5 at base; M 2 nearly parallel to M 3; M 3 free; CuA 1 and CuA 2 stalked at basal 1 / 5 of CuA 1; cell closed with weak cross vein. Hindwing slightly broader than forewing; costa nearly straight; apex sharply produced; termen oblique, slightly concave; venation with Rs and M 1 short stalked, beyond end of cell; M 2 absent; M 3 and CuA 1 short stalked; cell partly closed. Hind tibia orange white, smoothly scaled. Female unknown. Male genitalia (Figs. 10 a, 10 b). Basal lobes of uncus short, ovate, slightly emarginated at middle on caudal margin. Gnathos more or less large, gently arched, with less acute apical part. Costal bar narrow, without prominent median angle. Valva broad; costa concave before middle; cucullus shorter than basal part, semiovate, with round apex; ventral margin broadly expanded medially; pectinate plate short, with same length of combs; sacculus terminated before median expansion. Vinculum weakly sclerotized; apex slightly pointed. Aedeagus slender, slightly shorter than valva, bent medially; apex pointed, sclerotized on ventral margin; cornutus absent, but with a long patch of minute spinules. Distribution. Papua New Guinea (Morobe). Etymology. The species name is derived from the Latin, areola (= a small open space). Remarks. This new species has no M 2 in the hindwing, differing from the preceding new species, however, the combination of other characters including the male genitalia supports the placement of this species in Pectinimura.
