Eupoecilia quinaspinalis Zhang & Li, new species

(Figs. 1 a, 2a, 4a)

Type material. Holotype, ɗ, CHINA: Mt. Wuyi (26°54'N, 116°42'E), Fujian Province, 600–740 m, 19– 27.v.2004 (Haili Yu), genitalia slide No. ZX06252. Paratypes: 2 ɗɗ, 2 ΨΨ, same data as holotype.

Description. Adult (Fig. 1 a): Wing expanse 11.0–13.0 mm. Vertex and frons grayish white. Antenna dark brown. Labial palpus grayish yellow; terminal segment short, drooping. Thorax and tegula grayish yellow. Forewing elongate-subtriangular, costa moderately curved downward distally, apex rounded, termen almost obliquely straight; upperside ground color yellowish intermixed with dark brown; basal half of costa suffused with dark brown forming a costal streak, distal half with two irregular brownish marks, anterior one darker and larger; a large black spot at apex extending over cilia; several black spots present below apex occasionally; median fascia extending from end of costal streak to dorsal 2/5, slightly convex outwards, anterior 1/4 dark brown, posterior 3/4 light chestnut, almost uniformly broad throughout; a large ill-defined, triangularshaped light tawny patch between cell and apex; one black spot on lower angle of cell, another below it on dorsum; underside yellowish brown; cilia light yellowish, black around apex. Hindwing with upperside dark grayish; cilia tinged with grayish, having a fuscous subbasal band; underside slightly grayish. Fore and mid legs dark brown; hind leg grayish yellow, with dark brown on tarsus.

Male genitalia (Fig. 2 a): Socius slender, with a row of stiff, erect bristles from base to tip. Transtilla with triangular median process thin, acute distally, armed with minute distal spines; transtilla arms broadly oblong. Valva slender; costa gently concave slightly beyond middle; apex rounded; sacculus bearing a semicircular prominence ventro-distally about 1/3 length of sacculus with denticulate ventral edge. Juxta rectangular. Aedeagus moderate, with a short subapical projection 1/6 its length; vesica with a strong, straight subbasal cornutus 1/5 its length, five strong cornuti with broadly flattened base at distal 1/3, numerous minute distal cornuti.

Female genitalia (Fig. 4 a): Papilla analis broad. Apophysis posterioris short, same length as apophysis anterioris. Sterigma broad, bowl-shaped, notched medially; notch flanked by outward arc-shaped sclerites with denticulate edge. Ductus bursae as long as corpus bursae, with several thorns and large region of wrinkled sclerotization; ductus seminalis originating from anterior 1/3 of ductus bursae. Corpus bursae globular, with dense spines occupying posterior 4/5, with spines forming radiating arc at anterior edge.

Distribution. China (Fujian).

Diagnosis. The new species is similar to Eupoecilia wegneri (Diakonoff, 1941) in male genitalia, but it can be differentiated from the latter by the costa of the valva being gently concave, the sacculus with a semicircular prominence ventro-distally, the aedeagus with only one subapical projection, and the vesica having five strong distal cornuti (Fig. 2 a). In E. wegneri the costa of the valva is nearly straight; the sacculus bears a semi-elliptical prominence (Diakonoff, 1984: fig. 11); the aedeagus has a subapical and a second spiny projection; and the vesica has four strong distal cornuti (Diakonoff, 1984: fig. 12).

Etymology. The specific name is derived from the Latin prefix quina-, meaning five, and spinalis, meaning spinate, referring to the aedeagus having five strong cornuti at distal 1/3.
