Description. Male. Small cicadas. Body above black, finely with greyish pile.

Head ( Figs. 23 A–D). Head including eyes slightly narrower than base of mesonotum. Supra-antennal plate dull testaceous. Ocelli reddish. Eyes dark brown. Postclypeus black with dull testaceous laterally, transverse grooves of postclypeus, anteclypeus all black with grey scattered pile. Genae and lora black with dense, long silvery pile. Rostrum dark brown with black tip.

Thorax ( Figs. 23 C–D). Pronotum black with margins testaceous; central longitudinal fascia widened posteriorly, where it contains three small testaceous spots. Lateral part of pronotal collar slightly ampliate laterally and rounded; lateral angle well ampliate posterolaterally. Mesonotum with two central, discal, wedge-shaped fasciae; lateral margin and cruciform elevation testaceous.

Wings ( Figs. 23 A–B). Wings semi-transparent with basal half infuscated and venation fuscous. Fore wing with costal veins, basal membrane and extreme base testaceous; veins M and CuA narrowly separated when meeting at basal cell.

Legs ( Fig. 23 G). General color piceous; mid and hind tibiae annulated apically and basally with pale ochraceous. Fore femur with three spines: primary spine more slanted; secondary spine half as long as primary spine, almost erected; tertiary spine one-third as long as primary spine, slightly slanted.

Opercula ( Fig. 23 E). Operculum black in basal half, testaceous in apical half, coarsely covered with greyish pile; lateral margin of operculum slightly oblique. Meracanthus black to testaceous towards apex.

Abdomen ( Figs. 23 A–B, E–F). Abdomen slightly longer than head plus thorax. Timbal with three long ribs. Abdominal tergites piceous, with posterior margins of tergites III–VII and posterior portion of tergite VIII testaceous. Abdominal sternites testaceous with silvery scattered pile; sternites II–VII with a series of central piceous spots; sternite VII tapering posteriorly, with posterior margin obtuse; sternite VIII distinctly shorter than sternite VII, hind margin rounded.

Genitalia ( Figs. 24 A–D). Pygofer black at base, pale ochraceous laterally and pale testaceous posteriorly. Upper lobe of pygofer broadly triangular in lateral view, with apex obtuse. Median lobe of uncus small, apex slightly upswept in lateral view, paramedian area slightly convex in ventral view. Clasper moderately elongated, finger-shaped, apex obtuse, meeting the other one at base then separated anterolaterally.

Female ( Figs. 25 A–D). Female longer than male. Body beneath more testaceous red than in male, with short, dense golden pile. Operculum very small, posterior margin rounded. Abdominal tergites piceous, with dense, short silvery pile; posterior margins of tergites II–VII, posterior portion of tergite VIII all brightly testaceous; tergite IX brightly testaceous with a piceous Y-shaped marking dorsal-laterally, reaching to apex of dorsal beak. Abdominal sternites testaceous, with very small fuscous spot on posterior margin of each sternite (sometimes without such spot in some specimens); posterior margin of sternite VII with median incision very deep and broad, deep to about 4/5 the length of sternite VII; two oblique dark-reddish patches on anterolateral parts of sternite VII; two stigma of tergite IX dark-red. Dorsal beak of pygofer sharp, reaching beyond anal styles. Ovipositor sheath dark-reddish to black posteriorly, protruding beyond apex of dorsal beak. Other morphological characters similar to male.

Measurements. (2♂♂, 9♀♀), mean (range) (in mm). Body length: male 15.2 (14.2–16.8), female 21.1 (20.8–22.5); fore wing length: male 17.8 (17.0–18.5), female 20.7 (20.0–22.6); fore wing width: male 6.5 (6.4–6.6), female 7.4 (7.0–8.0); width of head including eyes: male 4.7 (4.7–4.7), female 5.3 (5.1–5.6); pronotum width (including pronotal collar): male 6.0 (5.9–6.0), female 6.9 (6.6–7.4); mesonotum width: male 4.9 (4.8–5.0), female 5.8 (5.4–6.2).

Distribution. China (Hebei, Zhejiang, Fujian, Hong Kong).

Remarks. The species was described by Distant (1905) under the genus Quintilia from Hong Kong, China. However, examination of the holotype and paratype ( Figs. 26 A–B) of this species deposited in BMNH revealed that this species is a member of Kosemia . Furthermore, Kosemia rubicosta ( Chou & Lei, 1997) (transferred from Leptopsalta by Sanborn (2013)) is proposed as a junior synonym of K. mogannia , based on morphology and the same type locality of related specimens.

Regarding to the status of Lycurgus sinensis Jacobi, 1944 ( Figs. 27 A–E), Jacobi (1944) described this species from Ningbo, Zhejiang Prov. of China. However, examination of the type specimens of this species deposited in MTD revealed that this species also should be a junior synonym of K. mogannia , based on morphology and the near type locality of related specimens.

This species can be easily distinguished from other species of Kosemia by the following characteristics: fore wing with basal half infuscated, and operculum black in basal half and testaceous red in apical half.
