Diagnosis. This new species is similar to E. hamata sp. nov. superficially, but can be recognized by having a subtriangular medial process on the costal margin of the valva, which is absent in the latter species.
Description. Adult ( Fig. 28 View FIGURES 28 − 35 ). Wingspan 10.0−11.5 mm in male. Head dull orange yellow. Antenna dusty yellow, as long as forewing; scape with a few black pecten bristles; flagellum unicolorous. Labial palpus with first and second segments yellowish brown tinged with darker scales on inner surface, dark brown on outer surface; third second yellowish brown, dark brown at base on outer surface. Thorax and tegula blackish brown. Forewing index 0.28−0.3, grayish black, shining dark purple, individual scales uniformly colored; retinaculum present; cilia grayish black, cilia line ill-defined. Hindwing pale grayish brown; male with a single short, slender evenly curved frenular bristle, female with two slender bristles, shorter one 0.7× length of longer one; cilia grayish brown in basal 1/3, pale gray in distal 2/3. Fore leg purplish brown; mid leg purplish brown, tarsus yellowish brown mixed with darker scales on ventral surface; hind leg yellowish brown.
Pregenital abdomen. In male, first tergum with medial 1/3 sclerotized; coremata present in eighth segment; eighth sternite 0.25× as long as wide, without caudal process; eighth tergite trapezoidal, without caudal process. In female, seventh sternite semicircularly concave at middle on posterior margin.
Male genitalia ( Fig. 59 View FIGURES 57 − 59 ). Vinculum with anterior and posterior margins parallel sided; medial process absent from ventrocaudal margin. Tegumen as deep as vinculum, semicircularly concave on anterior margin, convex at middle on posterior margin. Uncus with shouldered base forming a trapezoidal membraneous section with tegumen; uncus lobe as long as depth of vinculum, twisted at middle, basal half slightly expanded, punctate, distal half heavily sclerotized, hooked, smooth dorsally, hairy ventrally, apex melanized; sclerite absent between uncus lobes. Valva triangular, narrowed basally, sharply widened at 1/4, then narrowing to blunt apex; costal margin bearing small dentations at base, with a subtriangular medial process; basal flange large, smooth, hooked; bridging lobe absent between basal flange and valva; ventral margin with deep ventral lobe; basal margin with inconspicuous ‘secondary apodeme’ close to apodeme; inner surface unmodified. Juxta angled caudally, short and flat. Aedeagus stout, 1.5× length of valva, basal half being a pair of paddle-shaped sclerites, apex deeply concave at middle, dentate on dorsal surface of concavity. Bulbus ejaculatorius 3.0× length of aedeagus, slightly expanded at base, where ductus ejaculatorius is coiled, subdistal section not hypertrophied, distal section slightly expanded.
Female genitalia ( Fig. 84 View FIGURES 83 − 85 ). Ovipositor length 1.5 mm. Eighth tergite funnel-shaped, anterior 2/3 membraneous, tapered, forming slender process at middle on anterior margin; posterior half microtrichiate, with scattered setae near posterior margin. Eighth sternite rectangular, with sparse setae medially; anterior margin straight, posterior margin concave, slightly folded inward, forming a pair of shallow pockets posterolaterally. Ostium at middle of posterior margin of eighth sternite. Antrum weakly sclerotized; ductus bursae about 0.5× length of corpus bursae. Colliculum comprising a pair of sclerotized base-joined narrow bands extending from junction of ductus bursae and corpus bursae, crossing second ring to anterior end of corpus bursae; second ring at posterior 1/4 of corpus bursae, anteriorly produced to an elongate lance-like dorsal process with end extending to anterior 1/4 of corpus bursae; inception of ductus seminalis at middle on posterior margin of lance-like process of second ring. Corpus bursae ovate; signum absent.
Distribution. China (Fujian, Guangdong, Guangxi, Hong Kong).
Etymology. This species is named after the late Dr. Gaden S. Robinson for his great contribution to the study of Tineidae , and for commemorating the friendship between him and the corresponding author.
