Meleonoma corniculata sp. nov. Figs 4, 17 Type material. Holotype: China • ♂; Sichuan Prov., Chengdu, Anzi River, Baliping; 30.77°N, 103.22°E; 1706 m a. s. l.; 24 VI. 2016; Kaijian Teng & Xiaofei Yang leg.; slide no. ZXJ 19092, in NKU. Paratypes: • 2 ♂; 25 VI. 2016; other data same as for holotype; slide no. ZXJ 19344, in NKU 1 ♂; • Sichuan Prov., Xiaojin County, Mt. Sigu’niang; 3243 m a. s. l.; 4 VII. 2016; Kaijian Teng & Xiaofei Yang leg.; slide no. ZXJ 19094, in NKU. Diagnosis. The new species is similar to M. longisacca sp. nov. in male genitalia. It can be distinguished by the forewing with a median fascia, the saccus 1.5 × the length of the uncus, and the cornuti being several sclerites, each of which a large tooth in the male genitalia. In M. longisacca, the forewing lacks a median fascia, but represented by a median costal spot, the saccus is 2.5 × the length of the uncus, and the cornuti consist of a pile of spines. Description. Forewing length 7.0– 7.5 mm (Fig. 4). Head yellow, tipped with dark brown on occiput. Labial palpus yellow; first and second segments scattered with dark brown scales on outer surface; second segment forming an indistinct ring at apex; third segment 2 / 3 length of second segment. Antenna dark brown on dorsal surface, yellow on ventral surface; scape yellow apically on dorsal surface; flagellum alternated with yellow in distal 1 / 3 on dorsal surface. Thorax and tegula black. Forewing with costal margin arched, apex rounded; ground colour dark brown; median fascia yellow, extending from before middle of costal margin obliquely outward to before tornus, widened posteriorly; distal spot yellow, triangular, at distal 1 / 4, narrowed posteriorly, with sparse dark brown scales; plical spot black, placed at distal 2 / 5 of fold, not clearly distinguished from ground colour; discal and discocellular spots black, placed at basal 3 / 5 and at outer margin of cell, respectively, the latter larger, banded; fringe dark brown, with a yellowish white basal line. Hindwing and fringe brown. Legs yellow, with exceptions on ventral surface: foreleg dark brown except coxa yellow apically, tarsus yellow at base of basal tarsomere and at apices of basal two tarsomeres and yellow at apical tarsomere, femur of midleg with dark brown scales at base and at apex, tibia dark brown except yellow at middle and at apex, tarsus dark brown except yellow at apices of basal two and apical one tarsomeres, tibia of hindleg with scattered dark brown scales, tarsus with basal four tarsomeres dark brown except yellow at apices. Abdomen: Male genitalia (Fig. 17). Uncus lanceolate, with basal 1 / 3 uniformly wide, concave at beyond basal 1 / 3 and widened to basal 1 / 2, thereafter narrowed to narrowly rounded apex, setose laterally. Tegumen uniform in width medially; lateral arm narrowed to apex. Costal part of valva narrow at base, widened from base to basal 2 / 3, distal 1 / 3 uniformly wide except slightly narrower apex, rounded at apex, with several stout setae before middle, with fine hairs distally; apex rounded, with a denticle at ventral angle; ventral margin gently produced medially, with a sclerotised carina extending from base to basal 1 / 2 reaching at median width of costal part of valva, with spare setae; costal band concave basally, then gently arched distally; transtilla subovate. Sacculus triangular, weakly sclerotised in basal 2 / 3, distal 1 / 3 heavily sclerotised, with a small process at apex, with tufted setae basally. Saccus 1.5 × length of uncus, wide at base, narrowed from base to rounded apex. Juxta weakly sclerotised, U-shaped. Aedeagus tubular in basal 2 / 5, distal 3 / 5 narrowly banded; cornuti being several sclerites, each with a large tooth. Female unknown. Etymology. The specific epithet is from the Latin corniculatus, referring to the cornuti in the male genitalia. Distribution. China (Sichuan Province).
