Length (incl. teg.). – Male 9.5-10.5 mm , female 10.5-11.0 mm. Description. – General colour brown. Head ( Fig. 1 ) (including eyes) narrower than pronotum. Frons ( Fig. 2 ) brown; central carina longer than half length of frons; sublateral carinae shorter than central carina at about 1:1.4; lateral carinae light brown; carina between eyes light brown. Clypeus yellow, ecarinate. Vertex yellow, wider at anterior margin than long in middle line at about 1:16, without central carina, posterior corner with light brown macula, occipital margin carinate, brown. Pronotum brown, narrow, wider at widest part than long in middle line about 1:6.5, punctated beside central carina; anterior margin carinate. Mesonotum and mesopleura brown. Figs. 1-13. Euricania facialis Melichar : 1, vertex, pronotum and mesonotum, dorsal view; 2, frons and clypeus; 3, tegmina; 4, wing; 5, male genitalia, left side; 6, male anal segment, dorsal view; 7, aedeagus, dorsal view; 8, aedeagus, ventral view; 9, aedeagus, left side; 10, female genitalia, left side; 11, female anal segment, dorsal view; 12, gonophysis VIII, right side; 13, pregenital sternite. Scale bars: Figs. 1, 2, 10 = 1.25mm; Figs. 3, 4 = 3.2mm; Fig. 5 = 0.635mm; Figs. 6, 7-9, 11 = 0.4mm; Figs. 12, 13 = 0.5mm. Tegmina ( Fig. 3 ) with costal marginal fascia brown, with a yellow spot near middle; apical and inner margins with brown fasciae; disc with a transverse, brown fascia; common stalk of R1 and R2 longer than base cell. Wings ( Fig. 4 ) small, costal margin and inner margin with narrow, brown fasciae; apical margin with a broad, brown fascia. Legs yellowish, fore femora with 3-4 lateral spines; middle coxa with one basal spine; middle femora with 3-5 lateral spines. Abdomen brown or dark brown. Tegula dark brown. Eyes grey. Ocelli golden. Male genitalia. – Anal segment ( Figs. 5, 6 ) large, oblong in dorsal view ( Fig. 6 ), longer than wide at middle at about 1.5:1, lateral margins almost straight, apical margin slightly concave, basal margin strongly convex, ventral margin in profile ( Fig. 5 ) strongly convex; anal style set in middle but close to apex. Aedeagus with connective symmetrical. Phallobase ( Fig. 7 ) with dorsal process short, shorter than half length of phallobase in middle line about 1:3, directed cephalad and laterad; lateral process shorter than dorsal process at about 1:2. In ventral view, phallobase ( Fig. 8 ) constricted medially, apex concave medially. In profile view ( Fig. 9 ), phallobase not dilated near base. Genital styles ( Fig. 5 ) longer than wide at middle about 3.6:1. Female genitalia. – Anal segment ( Fig. 10 ) rather small, ventral margin in profile slightly convex; anal style set beyond middle, in dorsal view ( Fig. 11 ), apical margin concave, ventral margin strongly concave, lateral margins convex. Gonophysis VIII ( Fig. 12 ) shoe-shaped, basal part and anterior part in a right angle, anterior part dilated apically. Pregenital sternite ( Fig. 13 ) with anterior and ventral margins nearly straight medially. Bursa copulatrix as in fig. 10. Distribution. – China ( Fujian , Zhejiang , Jiangxi , Henan , Shanxi , Taiwan) ; Japan . Remarks. – This species is similar to E. longa , new species , but can be separated from the latter by its short spinose process of the male phallobase ( Fig. 7 ) and its long sublateral carinae of the frons ( Fig. 2 ). Host plants. – Silver chain, orange, tea plant, mulberry.
