Thubdora onsemiro Park, sp. nov. ASID: urn:lsid:zoobank.org:act: 451238C6-90B2-437E-ADBF-337886C7EFDF (Figs. 1 A–G) Type specimen. Holotype: male, Uganda, SW, Kabale Distr., Ruhija 2,330 m, 01°03.08′S 29°46.70′E, 4–7 xi 2007, leg. L. Aarvik & M. Fibiger, gen. slide no. CIS-7461, in NHMO. Diagnosis. The new species is distinguished from any known species of the genus by the forewing pattern, with broad, orange-white to pale orange median fascia. It is similar to the next species T. elgozmanyi sp. nov. in the forewing color pattern, but it is much smaller with a wingspan of 16.0 mm. (22.0 mm. in T. elgozmanyi sp. nov.), and it can be easily distinguished by the male genitalia with a longer uncus, the narrowly elongated cucullus distally, and the abdominal segment VIII, lacking the modified long rods anteriorly. Description. Male (Figs. 1A, B). Wingspan 16.0 mm. Head: Pale yellowish brown dorsally. Antenna slightly shorter than forewing; basal segment elongated, yellowish white, speckled with dark brown scales; flagellum shiny, yellowish white throughout, without annulations, shortly ciliate. Second segment of labial palpus (Fig. 1C) thickened, slightly arched ventral margin, dark brown in basal half, yellowish white beyond on outer surface, yellowish white on inner surface; 3 rd segment slender, strongly upturned, slightly shorter than 2 nd segment. Thorax: Tegula and thorax yellowish brown dorsally. Hind tibia not roughly scaled, with yellowish brown more or less appressed scales dorsally. Forewing with dark brown area in basal 1/3, outer margin slightly convex; antemedian fascia broad, yellowish white; area between antemedian fascia and postmedian fascia narrower than width of postmedian fascia; postmedian fascia broad, concave on inner margin; scattered with yellowish brown scales; costa arched beyond 3/4; apex obtuse; termen slightly convex medially; fringe yellowish brown, with narrow, yellowish white basal line; venation with distance between R 1 and R 2 more than 2.5× than that of R 2 and R 3; R 3 stalked with R 4 for basal 2/5; R 5 absent; M 1 remote from R 3+4 at base; M 2 well-developed; M 3, CuA 1, and CuA 2 on common stalk; distance between M 3 and CuA 1 shorter than that of CuA1 and CuA2; 1A+2A nearly not forked at base; cell weakly closed. Hind wing ground color yellowish white, scattered with yellowish brown scales in basal half; venation with M 2 absent; M 3 and CuA 1 nearly connate at base; cell closed. Abdomen (Fig. 1G): Spinose zones on dorsal surface broadly developed; tergite VIII with large, heavily sclerotized, crescent sclerite along anterior margin; sternite VIII extended into quadrate plate anteriorly with short, laterocaudal lobes directed outwardly. Male genitalia (Figs. 1 D–F): Uncus broadened distally, narrowed at middle, with truncate caudal margin. Basal plate of gnathos broadly developed, fan-shaped, with round caudal margin. Tegumen sclerotized, incised into inverted V-shape on anterior margin. Valva with costa nearly straight basally, then abruptly oblique, deeply concave; ventral margin nearly straight to lower corner of cucullus; sacculus not developed; cucullus elongated, foot-shaped, densely setose, expanded outwardly around lower corner. Juxta broad. Vinculum narrowly banded. Aedeagus slender, shorter than valva, narrowly produced, sclerotized on dorsal surface; cornutus a row of minute spinules apically. Female unknown. Distribution. Uganda (Kabale District). Etymology. This species’ name is derived from a Korean term “ onsemiro ”, meaning natural.
