Alienia laosa, 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 : 144-145

Alienia laosa sp. n. ( Figs 5 , 10 )

Type material. Holotype: male, Laos, Prov. Bolikhamsai, Tad Leuk Waterfall , 10.xi.2015 (legs. Bae YS & Park BS et al.), gen. prep. no. hhl-3542-1( NEFU).

Diagnosis. This species is similar to A. flavofasciata ( Figs 6 , 11 ) in superficial characters, but can be distinguished from the latter by the following characters: postmedial line of forewing almost straight; M1 vein common; hindwing rather dark; with cone-shaped clasper; ampullae pileus, with dense bristles; anellus long, hooked; juxta plate with two sclerite; carina with pushpin-shaped at apexes; vesica with 5 cornuti, basal four ones small, apical one larger. In A. flavofasciata , the postmedial line is waved; in male genitalia, the ampullae are beret shaped; the anellus rather short, hook-shaped, pointed apically; without sclerite at juxta plate; the vesica with 3 cornuti.

Description. Adult ( Fig. 5 ). Wingspan 10 mm. The basal, antemedial, subterminal and terminal lines areas of forewing grayish-brown; median and postmedial lines areas grayish- yellow, with dark brown band at costal area; basal line indistinct, presented as black dot costal area; antemedial line dark brown, arc-curved; median line yellow, indistinct, close to postmedial line, external oblique; postmedial line black, and narrower than antemedial line, smooth and slightly waved, parallel with median line; subterminal line brown, indistinct, mixed red, ends at tornus; terminal line formed by black dots; reniform stigma yellow, blurred; M1 vein with black near subterminal line. Hindwing brown; discal spot slightly dark, indistinct; terminal line pale yellow.

Male genitalia ( Fig. 10 ). Tegumen long and narrow laterally, apex slightly broaden; valva with dorsal and ventral margins slightly paralleled, asymmetrical, right one slightly larger; sacculus medially broad, with small basal process; clasper cone-shaped, rounded at tip; ampullae pileus-shaped, with heavily setae; left one with sharp ventral process, with a corner at dorsal margin. Juxta-anellus plate ovate; anellus well-sclerotised, apicaly longer, curved and pointed; juxta plate with two sclerite, left one rather small, triangular, rounded at top, right one larger, triangular, and sharp at top. Saccus V-shaped. Aedeagus cylindrical, coiled at apical half, with a sclerotised carina, and pushpin-shaped at apexes; vesica with 5 cornuti, basal four small grained, apical one larger triangle shaped, and strongly sclerotised.

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

Distribution. Laos (Prov. Bolikhamsai).
