Promalactis reniformis Kim and Park , sp. nov.

( Figures 1Q, R , 2I , and 4Q–S)

Diagnosis

This species is superficially close to Promalactis tricuspidata Wang and Li in the wing pattern, but can be easily distinguished by the female genitalia with a large, reniform lamella postvaginalis, deeply incised at middle.

Description

Adult ( Figure 1Q, R ). Head ( Figure 2I ): Frons and vertex white mixed with greyishbrown. Scape of antenna entirely white, except dark brown apex dorsally, as long as diameter of eye; flagellum white and dark brown alternately. Second segment of labial palpus dark brown dorsally, pale brown ventrally, gradually darker to apex, longer than third segment; third segment dark brown, except white at basal and apical parts. Thorax: Thorax and tegula brown dorsally. Wing expanse 7.0– 7.5 mm. Forewing ground colour yellowish-brown; white markings irregularly shaped and rarely surrounded by fuscous scales: one band-like, near at base; two spots connected at middle of one-third forewing; second band-like one, short and oblique from onethird posterior margin; third band-like one, short and oblique from one-half posterior margin, connecting to the other short band-like one, extending to before the tornus by fuscous scales; one reniform costal patch at two-thirds of costa; two apical spots surrounded by fuscous scales: smaller one at vein radius VI and large one at apex; fringes yellow from two-thirds of costal margin to two-thirds of outer margin. Hindwing lanceolate; fringes greyish-brown. Leg: hind tibia pale yellowish-brown densed with pale greyish-brown fringes; tarsus pale yellowish-brown, except white at basal parts of fifth and fourth segments.

Male genitalia. Unknown.

Female genitalia (Figure 4Q–S). Apophysis posterioris more than 1.5 times length of apophysis anterioris. Lamella postvaginalis large, reniform, incised deeply, setose on caudal margin with numerous orbicular sclerites laterally. Lamella antevaginalis small and trapezoid-shaped. Antrum hexagonal-like. Ductus bursae wide at base, membranous, gradually narrowed to one-third, then swollen forming a balloon-like part from one-third. Corpus bursae ovate; signum absent.

One female, Cuc Phuong Nat. Park, Vietnam, 196 m, 3–4 July 2008, JB Heppner, slide gen. no. SNU-9039/ S Kim.

Etymology

The specific name of the new species is derived from the Latin, reni (= kidney) plus forma (form -is) (= form), referring to lamella postvaginalis reniform of female genitalia.

Distribution

Oriental: Vietnam (North).
