Alienia cambodiaa, Qi, Mu-Jie & Han, Hui-Lin, 2017

Qi, Mu-Jie & Han, Hui-Lin, 2017, A description of three new species of the genus Alienia Fibiger, 2011 from Southeast Asia (Lepidoptera, Erebidae, Hypenodinae: Micronoctuini), Zootaxa 4269 (1), pp. 141-145 : 144

Alienia cambodiaa sp. n. ( Figs 3, 4 , 9 )

Type material. Holotype: male, Cambodia, Cardamom , 28–29.vi.2011 (legs. Bae YS et al.), gen. prep. no. hhl-3686- 1( NEFU) . Paratype. 1 male, Cambodia, Samkos , 7–8.ii.2015 (legs. Bae YS) ( NEFU) .

Diagnosis. This species is similar to A. laosa ( Fig. 5 ) in superficial characters, but can be distinguished from the latter by the following characters: antemedial line rather straight; postmedial line rather arc curved, strongly at anterior half; in male genitalia, left sacculus shorter than right one; clasper small and triangular at left valva, ampullae triangular, ventral process thorn-shaped; anellus finger-shaped, hooked, truncated at top; carina long and strongly curved, bandshaped; vesica with 5 cornuti, basal one slice-like, apical four nipple-shaped. In A. laosa , the antemedial line curved, postmedial line is slightly waved; in male genitalia ( Fig. 10 ), the ampullae are pileus-shaped, ventral plate with a spine; the anellus is long and hook-shaped, with pointed apex; carina sclerotised pushpin-shaped apically; the vesica with 5 cornuti, apical one large, triangle-shaped, basal four small grained.

Description. Adult ( Figs 3, 4 ).Wingspan 10–11 mm. The subterminal and terminal lines areas of forewing grayishbrown, rather darker; basal, antemedial, median and postmedial lines areas pale yellow, and slightly brown at costal margin; basal line indistinct, represented by black dot at costa; antemedial line dark brown, slightly straight and internally oblique, with concave at 2A vein; median line thin yellow, indistinct, rather broad, and close to postmedial line, externaly oblique; postmedial line black, slender, smooth curved, the anterior part clearly arc-shaped; subterminal line brownish-red, indistinct, ends at tornus; terminal line formed by black dots; reniform stigma blurred. Hindwing dark brown; discal spot small, slightly dark, indistinct; terminal line pale yellow.

Male genitalia ( Fig. 9 ). Tegumen long and narrows evenly, about 2 times as long as vinculum. Valva gradually broadens from base to apex, asymmetrical, left one slightly larger; sacculus gradually sharped from base to apex, left shorter than right; clasper weak, triangular; ampullae triangular, with sparse short setae, ventral process thorn-shaped, left one more incisive than right. Juxta-anellus plate ovate; anellus well-sclerotised, finger shaped, hooked, truncated apically. Saccus triangular, pointed at bottom. Aedeagus cylindrical, straightness at anterior half, coiled at apical half; vesica with 5 cornuti, anterior one slice like, other four small, nipple-shaped.

Etymology. This species name refers to the country of the type locality.

Distribution. Cambodia (Cardamom, Samkos).
