( Figures 1 View Figure 1 (a), 1(b), 2(a–c))

Diagnosis

This species is close to P. fortijuxtalis Wang, Du & Li, 2013 in forewing pattern, but can be distinguished from the latter species by the antemedial band connected to the postmedial band without fuscous suffusion and the absence of white apical patch of forewing. The male genitalia are also similar to those of P. fortijuxtalis , but can be differentiated by the posterior margin of juxta not sinuate and the basal margin rarely haired, and the anterior margin of the genitalia triangular, not rounded as that of P. fortijuxtalis .

Description

Adult ( Figure 1 View Figure 1 (a), 1(b)). Head: Frons dark brown, vertex white basally, occiput dark brown. Antenna: Scape white entirely 1/2 length of diameter of eye; fragellum dark brown and white alternately dorsally. Labial palpus: 2nd palpomere pale greyish dark brown; 3rd palpomere blackish dark brown same length as 2nd palpomere. Thorax: Thorax and tegula blackish dark brown. Wing expanse 9.5–10.0 mm. Forewing ground colour brownish yellow; four bands all white edged with fuscous scales: subbasal band slightly arched toward wing base, not reaching costal margin; antemedial band relatively broad at 2/5 of forewing; medial band oblique toward apex, connected to postmedial band; costal patch at 3/4, reaching beyond half across wing, semi-ovate; fringes greyish dark brown. Hind wing more or less lanceolate; ground colour pale greyish brown; fringes greyish brown.

Male genitalia ( Figure 2 View Figure 2 (a–c)). Uncus large, broadly rounded, incised apically, forming two lateral lobes. Gnathos sclerotized, wide at base, up-turned at 1/2, gradually narrowed to apex, short-tongue-shaped, slightly longer than uncus. Valva with costal margin convex basally, before medial projection; cucullus horn-shaped at 3/5, setose after concave to apex; saccular margin 5/9 length of costal margin. Juxta large, bifurcate medially forming two large lobes, as long as valva: lobe with lateral margin roundly edged, covered by dense setose after 2/5 to apex, as long as valva. Saccus large, triangular. Phallus slightly bent at middle, as long as valva. Cornutus absent.

Female unknown.

Holotype

Male, Cambodia, Kampot Province, Bokor National Park , 13 July 2012, Bae et al., gen. slide no. 9603/ S Kim.

Etymology

The species epithet, ceratiscus , is derived from the Greek, cerato- (=horned) plus - iscus (=Greek diminutive suffix), referring to the horn-shaped cucullus of valva of the male genitalia.
