description: Sorolopha nanlingica, sp. nov.
(Figs. 2, 5)
Holotype Male. China, Mt. Nanling (23°20' N, 115°23' E), Guangdong Province, 18.XI.2006, leg. Liusheng Chen, genitalia slide no. YHL07105.
Diagnosis. This new species is easily recognized by its distinctive forewing pattern, which is simple with a single large white spot in the apical area; the latter is situated below the apex with its outer edge reaching the termen between the apex and M3. Most species of Sorolopha and Sorolophae usually possess a forewing pattern consisting of a dorsal blotch, median fascia, and a large apical spot, but sometimes the dorsal blotch is indistinct or replaced by a subbasal fascia; the apical spot is pale fuscous, fuscous, blackish fuscous or brown, brownish grey, often suffused with ochreous. The presence of a white apical spot is diagnostic for S. nanlingica. The male genitalia of this new species are very similar to those of S. ferruginosa Kawabe, 1989. They can be separated from those of the latter by the valva with the neck protruding dorsally, and the ventral prominence of the cucullus gradually broadened towards the distal part and less than twice the width of the apex of the cucullus. In S. ferruginosa, the neck of the cucullus is not protruded dorsally, the ventral prominence of the cucullus is semicircular, and it s widest in the middle, more than twice the width of the apex of the cucullus.
Description. Adult (Fig. 2). Head: Vertex roughly scaled, fuscous. Frons black. Antenna fuscous. Labial palpus porrect, median segment expanded, terminal segment pointed.
Thorax: Tegula pale brownish fuscous. Thorax fuscous. Foreleg and midleg deep fuscous; hindleg pale fuscous, hind tibia in male unmodified, lacking hair pencil. Forewing length 7.5 mm, narrow basally, slightly broadened distally, costa nearly straight, apex distinct, termen oblique; upperside fuscous, markings irregular; two basal pairs of costal strigulae obscure, distal seven pairs grayish green; strigulae five and six extending to base of R4; short band inside of lower angle of cell, its lower edge reaching base of CuA1; small white blotch outside of upper angle of cell between R4 and M2; black oblique streak adjacent to white blotch extending from 1/3 length of R3 to end of CuA1, surrounding a white ovate spot in the apical region between apical part of R4 and distal 2/3 of M3, with three short black lines between R5 and M3, each line between a pair of adjacent veins; a few small black dots scattered on distal part of wing and dorsum; area upper to dorsum green mixed with fuscous; cilia fuscous suffused with pale fuscous, white on apex; underside deep fuscous except white costal strigulae and white area overlapped by hindwing. Hindwing upperside fuscous except for white area of overlap by forewing; cilia pale fuscous, with fuscous baseline; underside fuscous.
Abdomen: Male genitalia (Fig. 5) with tegumen high and narrow. Uncus obtuse. Socius slender, pendant, reaching mid-length of tegumen, apex with short spines. Gnathos weak, a narrow band. Valva with neck short, narrow, no more than 1/3 length of maximum width of cucullus, with scattered short spines; sacculus broad, with sparse spines; cucullus spined, with basal 3/5 expanded gradually to a broad ventral prominence, densely setose along ventral edge, distal 2/5 narrow, apex rounded. Phallus curved, without cornuti.
Female unknown.
Etymology. The specific name is from the type locality, Mt. Nanling, Guangdong Province.
