( Figs. 1, 3 , 5, 6 , 8 ) Diagnoses . Gisilia melanobasis is similar to G. thoracista ( Fig. 4 ) in external appearance, but larger than the latter (forewing length 3.1–3.8 mm ). Gisilia melanobasis is also similar to G. gielisi Koster in having a cucullus and a distal saccular protrusion in the valva but differs from the latter in having a narrower cucullus and a longer phallus. The female genitalia of G. melanobasis lack a signum and have a sclerotized band in the ductus bursae not reaching the ostium bursae. These two characteristics distinguish G. melanobasis from other congeners with a sclerotized band in the ductus bursae. Description . Head—Vertex dark brown; frons dark brownish grey, tinged with pale yellowish grey laterally. Antenna 1/2 as long as forewing; scape dark brown; flagellum dark brown on basal 3/5, pale yellowish grey on apical 2/5. Labial palpus upcurved, pointed apically; 1 st palpomere dark brown; 2nd palpomere dark brown on outer surface, pale greyish orange on inner surface, 5× longer than 1 st palpomere ; 3rd palpomere dark brown on outer surface, pale greyish orange on inner surface, as long as 2nd palpomere. Thorax—Tegula, mesonotum dark brown; mesoscutellum pale greyish orange. Foreleg with coxa and femur lustrous pale yellowish grey on outer surface, dark brown on inner surface; tibia dark brown dorsally, pale brownish grey ventrally, with pale yellowish grey band apically; tarsomere dark brown, with pale yellowish grey ring apically. Midleg with coxa pale brownish grey; femur lustrous pale yellowish grey on outer surface, dark brown on inner surface; tibia dark brown dorsally, pale greyish orange ventrally, with pale yellowish grey band apically; tarsomere dark brown, with pale yellowish grey ring apically. Hindleg with coxa dark brownish grey; femur dark brownish grey on outer surface, lustrous pale yellowish grey on inner surface; tibia dark brown dorsally, lustrous pale yellowish grey ventrally, with pale yellowish grey band apically; tarsomere dark brown dorsally, dark brownish grey ventrally, with pale yellowish grey ring apically. Forewing length 3.8–4.4 mm , pale greyish orange, suffused with dark brownish grey on costal and apical areas; basal area dark brown; a dark brown spot at middle and distal end of discal cell, and at middle of CuP fold; fringe dark greyish brown. Hindwing and fringe brownish grey. Male abdominal segment VIII ( Fig. 5)—posterior process of tergite ( Fig. 5b ) with large triangular basal plate and small triangular distal plate; sternite long-subtrapezoidal, with two elongate process ( Fig. 5c ); pleural area expanded, densely wrinkled ( Fig. 5b ). Male genitalia ( Fig. 6 )—Uncus absent; tegumen round laterally, slightly bulged apically; tuba analis slightly sclerotized ventrally. Valvae asymmetrical; each valva rectangular in basal 2/3, linguiform in distal 1/3; right cucullus narrowly round apically, setose, with two rows of spiniform setae along marginal area; left cucullus subtriangular apically, same as right cucullus in setal area; sacculus gradually broadened to base, with small, digitate, setose process distally on left valva, with narrowly-round, setose lobe on right valva. Juxta triangular, ankylosed with phallus. Vinculum broadly rounded laterally, slightly concave medially; saccus sub-hexagonal, with elongate process medially. Phallus heavily sclerotized, bi-sinuous, with apical 3/5 laterally flattened, acuminate apically; basal 1/5 of phallus narrowly curved. Female genitalia ( Fig. 8 )—Oviscapt ( Fig. 8a ) elongate, heavily sclerotized, hastate apically, 1/2 as long as apophyses posteriores; oviscapt cone narrow, sclerotized lateroapically, sparsely setose, with membranous collar apically. Apophyses posteriores as long as apophyses anteriores. Sternite VII adjacent to ostium bursae emarginated ( Fig. 8b ). Ductus bursae narrowed near ostium bursae, once coiled near anterior 1/3, with a narrow band-like sclerite in anterior 4/5; ductus seminalis arising near ostium bursae. Corpus bursae ( Fig. 8c ) elliptical, with medially-constricted quadrate sclerite on neck near ductus bursae; signum absent. FIGURES 1–4 . Adults of Gisilia . 1.

Distribution . South Korea . Etymology . The species epithet, melanobasis , is derived from the Greek words, ‘ melanos ’ and ‘ basis ’, meaning “black” and “bottom” respectively, and refers to the dark brown basal area of the forewing.
