Name
Promalactis senispina Kim sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype: ♂, Laos, Bolikhamsai prov., Phou Khao Khouay National Protected Area National Park, 322 m, 1 April 2016, Bae et al., gen. slide no. 9860/S. Kim. [Holotype is deposited in INU.]
Diagnosis
This species is externally similar to P. lophacantha Wang, Du & Li by having irregular bands of forewing, but it can be easily differentiated by the extended saccus and the prolonged aedeagus, which bears six projections in male genitalia.
Description
Adult (Fig. 2F). Head: frons pale yellowish white; vertex white; occiput white. Antenna: scape white entirely, longer than diameter of eye; flagellum dark brown and white alternately from base to apex dorsally. Labial palpus: 2nd palpomere pale yellowish brown, slightly longer than 3rd palpomere; 3rd palpomere pale yellow tinged with white, except dark brown apically. Thorax: thorax and tegula dark brown. Wingspan 7.0–7.5 mm. Forewing ground color yellowish brown; three bands, one costal patch, and one apical patch all white: one subbasal band traversed from costal margin to posterior margin near wing base; one antemedial band broad, slightly oblique toward wing base, traversed from costa to posterior margin; one medial band connected to postmedial short band on lower margin of cell; one apical patch accupied after 3/4 of forewing to apex; fuscous scales scattered followed by posterior margin of forewing; fringes yellow, except pale yellowish white near medial and postmedial bands. Hindwing ground color grayish dark brown; fringes dark grayish brown.
Male genitalia (Fig. 4F–I). Uncus wide at base, gradually narrowed to pointed apex, setose apically, as long as gnathos. Gnathos wide at base, gradually narrowed to apex, thumb-shaped apex, bearing sclerotized and serrated projection inner margin, as long as uncus. Valva symmetrical; costal margin convex after middle; saccular margin moderate, setose from 1/2 of its length to apex. Saccus extremely long, 1.5 times longer than valva. Aedeagus straight, elongated, as long as total length of genitalia, with six spines, differently sized apically; cornutus absent.
Female unknown.
Distribution
Laos (central; new).
Etymology
The specific name is derived from the Latin, seni (= six) and -spina (= spine), referring from the aedeagus bearing six spines in males.
