Diagnosis. The male genitalia of this new species are similar to those of E. carinata sp. nov., but can be distinguished from the latter by the uncus lobe hooked at the apex, the valva with an elliptical basal process and a digitate medial process, the aedeagus differentiated into a horned ventral section and an S-shaped dorsal section, both sections without carina. In E. carinata sp. nov., the uncus lobe is sharp at the apex, the valva has an almost rounded basal flange and a small rounded-triangular medial process, the aedeagus is not differentiated into two sections, but has carinae. Description. Adult (Fig. 31). Wingspan 9.0−17.0 mm. Head yellowish white to pale orange yellow. Antenna 0.9× length of forewing; scape pale orange yellow above, yellowish white below, with a few blackish pecten bristles; flagellum unicolorous, dusty yellow. Labial palpus yellowish brown to pale orange brown, with scattered darker scales on inner surface, dark brown on outer surface. Thorax and tegula brown to blackish brown. Forewing index 0.3−0.35, uniformly yellowish brown except individual scales dark tipped in some specimens; retinaculum present; cilia pale yellow with brown tips, with three well-defined cilia lines. Hindwing grayish brown; male with a single short, slender evenly curved frenular bristle, female with two or three slender bristles of equal length; cilia pale gray. Fore and mid legs grayish brown mixed with darker scales; hind leg yellowish brown mixed with darker scales. Pregenital abdomen. First tergum with medial 1 / 3 sclerotized. In male, coremata present in eighth segment; eighth sternite 0.25× as long as wide, without caudal process; eighth tergite tapered, without caudal process. In female, seventh sternite deeply concave at middle on posterior margin. Male genitalia (Fig. 62). Vinculum gently concave at middle on anterior margin, semicircularly concave on posterior margin; medial process absent from ventrocaudal margin. Tegumen 0.5× depth of vinculum, gently concave on anterior margin, semicircularly concave on posterior margin, articulated with vinculum, forming an Xshaped rim at joint. Uncus with broad furcate base, forming a bell-shaped membraneous section with tegumen; uncus lobe 2.0× depth of medial vinculum, not twisted, basal half fused, distal half separated, with sparse short setae, apex melanized, slightly extrorse; basal half and distal half linked by membrane; digitate process arising from base of uncus lobe laterally, linked with apodeme by narrow membrane; sclerite absent between uncus lobes. Valva triangular, broad at base, narrowed to blunt apex; costal margin straight, with a lobate, almost rounded basal process and a large, digitate medial process; ventral margin convex in basal 2 / 5, forming a shallow ventral lobe, distal 3 / 5 somewhat straight; basal margin concave in semicircle ventrally, with small, triangular ‘secondary apodeme’ close to apodeme; inner surface unmodified. Juxta fused with vinculum angularly, stout, short, about 0.15× length of aedeagus, slightly humped in dorsal midline. Aedeagus 0.8× length of valva, double-walled, differentiated into two sections: ventral section stout, gently narrowed to apex, distal 1 / 3 bifurcate, forming two horned processes, slightly bent dorsad; dorsal section arising from half to two thirds of ventral section, tubular, curved in S shape, apex blunt. Bulbus ejaculatorius 2.5× length of aedeagus, slightly expanded at basal 1 / 4, where ductus ejaculatorius is coiled; subdistal section expanded semicircularly; distal section expanded, narrower than subdistal section. Female genitalia (Fig. 85). Ovipositor length 2.6−3.2 mm. Eighth tergite rectangular, posterior margin slightly concave at middle, with sparse setae, microtrichiate on posterior half. Eighth sternite bowknot-shaped, protruded ventrad, forming two plates: internal plate with a minute knot at middle near posterior margin, which is surrounded by a rounded, weakly sclerotized section with radiate crimples; external plate microtrichiate posterolaterally, with a pair of large, triangular processes on posterior margin. Ostium at middle of eighth sternite, between two plates. Antrum short, cylindrical; ductus bursae as long as corpus bursae. Colliculum comprising a clubbed process with spinose, bifurcate, bean-shaped apices arising from a broadly flanged, flower-like apodeme at junction of ductus bursae and corpus bursae, invaginated into corpus bursae to level of second ring; second ring at posterior 1 / 5 of corpus bursae, with a short, apron-like dorsal extension anteriorly; inception of ductus seminalis at middle of apron-like extension. Corpus bursae ovate, posterior 1 / 5 thick-walled; signum absent. Distribution. China (Fujian, Gansu, Guizhou, Hainan, Henan, Hunan, Hubei, Jiangxi, Shaanxi, Sichuan, Yunnan, Zhejiang). Etymology. The specific name is derived from the Latin prefix curv-, meaning curved, and the Latin dorsalis, meaning dorsal, referring to the dorsal section of the aedeagus curved in S shape. Remarks. The valva is variable in this new species (Figs 62 a, b): the apex is usually blunt, but has a mastoid process in some specimens; the digitate medial process of the costal margin is usually located at middle, but placed near distal 1 / 3 and somewhat triangular in some specimens.Published as part of Yang, Linlin, Wang, Shuxia & Li, Houhun, 2014, A taxonomic revision of the genus Edosa Walker, 1886 from China (Lepidoptera, Tineidae, Perissomasticinae), pp. 1-102 in Zootaxa 3777 (1) on pages 24-26, DOI: 10.11646/zootaxa.3777.1.1, http://zenodo.org/record/24982
