Edosa eminens Yang, Wang & Li , sp. nov.
( Figs 3 View FIGURE 3 , 33 View FIGURES 28 − 35 , 64 View FIGURES 63 − 64 )
Type material. Holotype ♂, CHINA: Mt. Jianfeng (18°50΄N, 108°43΄E), Hainan Province, 940 m, 6.vi.2007, leg. Zhiwei Zhang & Weichun Li, genitalia slide No. XYL08065.
Diagnosis. This new species is similar to E. baculiformis sp. nov., but can be distinguished by the sinuate uncus lobe with pointed apex and the ventral process of the valva not concave on its lower margin; in the latter species, the straight uncus lobe is rounded at the apex, the ventral process is concave at middle on its lower margin and forms two small appendages.
Description. Adult ( Fig. 33 View FIGURES 28 − 35 ). Wingspan 15.0 mm in male. Head dull yellow. Antenna dull yellow, almost as long as forewing; scape with a few black pecten bristles; flagellum unicolorous. Labial palpus yellowish brown on inner surface, dark brown on outer surface. Thorax and tegula blackish brown. Forewing index 0.3, brown, individual scales dark-tipped; retinaculum present; cilia yellowish brown with darker tips. Hindwing yellowish brown, with a single short, slender evenly curved frenular bristle; cilia grayish brown. Fore leg blackish brown; mid femur and tibia blackish brown, tarsus and spurs yellowish brown; hind leg yellowish brown.
Pregenital abdomen. In male, first tergum sclerotized in middle of frame, about 2/5 of tergum; coremata present in eighth segment; eighth sternite 0.3× as long as wide, without caudal process; eighth tergite trapezoidal, without caudal process.
Male genitalia ( Fig. 64 View FIGURES 63 − 64 ). Vinculum gently convex on anterior margin, arcuately concave at middle on posterior margin, medial process present on ventrocaudal margin, very short. Tegumen slightly concave at middle on both margins, 0.5× depth of vinculum. Uncus with broad fan-shaped base interrupted by traces of uncus lobes, not forming a membraneous section with tegumen; uncus lobe 1.2× depth of vinculum, sinuate, not twisted, broad at base, slightly protuberant dorsally, narrowed to middle and slightly curved to dorsal side, distal 1/4 needle-like, apex pointed, basal 1/4 to half punctate and hairy; sclerite absent between uncus lobes. Valva elongate, broad at base, slightly narrowed to rounded apex; costal margin almost straight, unmodified, without basal flange; ventral margin slightly concave at middle, without ventral lobe, with a prominent, quadrangular process at base, lower margin of process oblique; basal margin with ‘secondary apodeme’ close to ventral margin, represented only by a shallow convexity; inner surface unmodified. Juxta reflexed anteriorly along inner surface of vinculum, very short, flat, jar-shaped, about 0.15× length of aedeagus. Aedeagus stout, 0.8× length of valva, double-walled, slightly bent ventrad, with shallow dorsal emargination. Bulbus ejaculatorius 6.0× length of aedeagus, slightly expanded at basal 1/6, where ductus ejaculatorius is coiled, subdistal section not hypertrophied, distal section slightly expanded, as broad as basal 1/6.
Female unknown.
Distribution. China (Hainan).
Etymology. The specific name is derived from the Latin eminens , meaning prominent, referring to the prominent, quadrangular ventral process.
