( Figs. 2 View FIGURE 2 E, 3D, 7)
Euplocamus tanylopha Meyrick, 1932 View in CoL , Exotic Microlepidoptera, 4: 329. Type locality: Sinsuiei ( Formosa).
Description. Male. Head: Vertex and frons covered with dense, erect, pale ochreous scales, lightly mixed gray. Antenna length about 4.0– 5.3 mm ( Fig. 2 View FIGURE 2 E), about 0.6 x as long as forewing; scape brownish gray mixed with white scales; flagellum dark fuscous. Maxillary palpus very short, indistinct with dark gray scales. Second segment of labial palpus with dense brownish gray scales mixed with white scales mesally, dark gray, mixed with white scales laterally; 0–2 lateral bristles. Thorax: Dorsally covered with light yellow-ochreous scales mixed with black; large double posterior crest with white apex. Foreleg black; midleg fuscous, covered with black dark brown scales; hindleg covered with brownish gray scales; hind tibiae bearing long pale brown hairs; all segments covered with white scales. Forewing length 6.6–8.7 mm; forewing rather elongate, slightly rounded apically, about 3.3–3.5 x as long as wide including fringe (about 3.2–3.4 x as long as wide excluding fringe); ground color brownish gray, numerous small black spots coalescing posteriorly into thick interneural streaks; confluence of streaks forming quadrate spots on costa near base and at 1/3, and broad somewhat oblique blotches from costa beyond middle and at 3/4; a large tuft of long, erect, ochreous whitish and blackish scales around fold beneath middle; basal third of cilia dark gray, remainder gray, with barred ochreous-whitish suffusion. Fringe short, black in apical region, long at termen, consisting of black scales; all veins present and separate, R1 arising from 1/3 of discal cell; R5 ending at apex; 1A+2A 3.0 x as long as 1A; chorda present, extending to crossvein R3-R4+5; retinaculum elongate, curled at apex ( Fig. 3 View FIGURE 3 D). Hindwing relatively elongate, rounded apically, 1.8–2.0 x as long as wide including fringe (2.5–2.7 x as long as wide excluding fringe); ground color brownish gray mixed with broad and narrow scales, except basal 3/4 of costa with brownish gray slender scales; fringe mostly short, long at basal posterior of margin area, consisting of brown to gray scales; crossvein M-CuA absent or present, M branched in discal cell ( Fig. 3 View FIGURE 3 D). Abdomen: Dorsally black, irrorated with glassy light gray scales at the intersegemental junctions; grayish white ventrally; segment VIII with coremata absent. Male genitalia ( Fig. 7 View FIGURE 7 ) with uncus complex, consisting of 4 sclerotized lobes, dl cristate, densely covered with minute knobs; ll triangular, confluent with dl; al bilobed, small, triangular, bearing spinules dorsally; vl small, digitate, more lightly sclerotized. Vinculum semicircular, nearly straight at anterior margin in ventral view. Valva strongly elongate, inwardly with a median keel, ventrally with a small, distinct, digitate projection at middle; inner side with dense, long thick bristles on posterior half. Juxta absent. Aedeagus straight, 1.0 x length of valva, apex slightly curved ventrally, inflated basally, cornuti absent. Female unknown.
Material Examined. Holotype with the label: “Sinsuiei, Formosa, SI. 18.3.26 ”, deposited in BMNH, UK. Japan: Ryukyus (Okinawa): 13, Ishigaki Island, Mt. Omoto, 2.IV.1980, OPU; 13, Ishigaki Island, Busamadake, 19.III.1981, Y. Arita, NSMT; 13, same locality, 17.XI.1980, larva collected (em. 12.I.1981, larva in decaying wood), Y. Arita, NSMT. 13, Iriomotezima Island, Uehara (Taketomi-cho), 24.III.2001, T. Saito, OPU.
Host. Decaying wood.
Distribution. Taiwan; Japan (Okinawa) (new to Japan).
Remarks. The species was reported from Taiwan as Euplocamus tanylopha ( Meyrick, 1932; Davis, 1992; Robinson & Tuck, 1996; Wang et al., 2000; Hua, 2005). We transfer it to Psecadioides based on characters of the uncus and the valva (see the description of the genus).
