Material examined. 1 ♀ (Lectotype, here designated), Type (in a red circle), China 94-156 (Ta-chien-lu; Sichuan, Kangding), Tibicina chinensis Dist. type (handwriting), cotype ♀/ Cicadetta chinensis (Distant) / Michel Boulard det. 1976, BMNH (E) # 909420; 1 ♀ (Paralectotype), same data as lectotype, BMNH (E) # 909419; 1 ♂, 1 ♀ ( NWAFU), Sichuan Prov., Wolong National Nature Reserve, 1856m, 26 -vii- 1981, coll. Wu Jianguo.

Description. Male. Body almost black with reddish brown or testaceous red markings, furnished with thick, silvery pile.

Head ( Figs. 20 View FIGURE 20 A–D). Head including eyes slightly narrower than base of mesonotum; vertex black with grey scattered pile, posterior margin of vertex dull ochraceous. Ocelli dark red. Eyes dark brown. Postclypeus black with testaceous laterally; transverse grooves of postclypeus and anteclypeus black with grey scattered pile. Genae and lora black with dense, long silvery pile. Rostrum black.

Thorax ( Figs. 20 View FIGURE 20 C–D). Almost black. Anterior and posterior margins of pronotum narrowly dark reddish. Lateral part of pronotal collar ampliate laterally and slightly angled. Mesonotum black with two discal spots and cruciform elevation (excluding centre) dull ochraceous.

Wings ( Figs. 20 View FIGURE 20 A–B). Fore wing with costal, basal and ulnar veins testaceous; veins M and CuA meeting basal cell with their stems completely fused; transverse veins at base of second and third apical cells slightly infuscated; basal membrane testaceous. Hind wing plaga brown, broad along veins 2 A and 3 A to its distal end and inner margin of anal lobe; ambient vein of cubital cell 2 and anal cell 1 infuscated.

Legs ( Fig. 20 View FIGURE 20 G). General color black with dense, short silvery pile. Longitudinal fascia to femur, apical area of tibiae and apex of coxa, all testaceous. Fore femur with three strong spines beneath all slightly slanted and reddish brown, decreasing in size from primary to tertiary spine; a tiny spine divided from tertiary spine.

Opercula ( Fig. 20 View FIGURE 20 E). Operculum rounded and not extending to posterior margin of tympanal cavity, generally dark red or testaceous, black at base, coarsely covered with greyish pile. Meracanthus black.

Abdomen ( Figs. 20 View FIGURE 20 A–B, E–F). Abdomen longer than head plus thorax. Timbal with three long ribs. Abdominal tergites and sternites black with posterior segmental margins narrowly testaceous red. Abdominal sternite VII tapering caudally, posterior margin rounded; sternite VIII dark reddish, slightly shorter than sternite VII, hind margin rounded.

Genitalia ( Figs. 21 View FIGURE 21 A–D). Pygofer almost black, furnished with short silvery pile. Dorsal beak of pygofer moderately long, spine-shaped, narrowly pointed at apex. Upper lobe of pygofer slightly acute in lateral view, apex obtuse; basal lobe of pygofer tending to be broadly angled in lateral view. Median lobe of uncus small, apex somewhat upswept in lateral view, paramedian area slightly convex in ventral view. Clasper moderately elongated, digitate, meeting the other one at base then separated and strongly curving anterolaterally, with a tiny spine at median part of inner margin; apex obtuse.

Female ( Figs. 22 View FIGURE 22 A–H). Female longer than male. Supra-antennal plates testaceous. Central longitudinal fascia of pronotum, two deltoid spots of mesonotum and cruciform elevation dull ochraceous ( Fig. 22 View FIGURE 22 C) or yellowish ( Figs. 22 View FIGURE 22 A, F). Central longitudinal fascia of pronotum with posterior margin not ampliate ( Fig. 22 View FIGURE 22 A) or widened posteriorly but contains one small black spot ( Figs. 22 View FIGURE 22 C, F). Veins M and CuA of fore wing contiguous at basal cell but not fused ( Figs. 22 View FIGURE 22 A, C, E, F), transverse veins at base of second and third apical cells slightly infuscated ( Figs. 22 View FIGURE 22 A, F) or not ( Fig. 22 View FIGURE 22 C). Operculum very small, testaceous ( Fig. 22 View FIGURE 22 B) or dark reddish ( Figs. 22 View FIGURE 22 D, E), black at base, posterior margin rounded. Meracanthus broadly triangular, very small, apex pointed. Abdominal tergites almost black, with posterior margins narrowly testaceous, furnished with dense, short silvery pubescence; tergite IX ( Fig. 22 View FIGURE 22 G) black dorsally, whilst testaceous laterally. Abdominal sternites black with posterior margins of sternites III–VI testaceous red ( Figs. 22 View FIGURE 22 A, F) or dark reddish ( Fig. 22 View FIGURE 22 C), furnished with dense, silvery pubescence; posterior margin of sternite VII with median incision very deep and broad, deep to about 4 / 5 the length of sternite VII ( Fig. 22 View FIGURE 22 H). Dorsal beak of pygofer ( Fig. 22 View FIGURE 22 G) sharply pointed at apex, distinctly reaching beyond anal styles. Ovipositor sheath ( Figs. 22 View FIGURE 22 G, H) dark-reddish, slightly protruding beyond apex of dorsal beak. Other morphological characters similar to male.

Measurements. (1 ♂, 1 ♀) (in mm). Body length: male 22.4, female 27.0; fore wing length: male 24.7, female 27.1; fore wing width: male 8.2, female 9.7; width of head including eyes: male 6.1, female 7.1; pronotum width (including pronotal collar): male 7.8, female 9.2; mesonotum width: male 6.3, female 7.9.

Distribution. China (Hebei, Hubei, Sichuan).

Remarks. The species C. chinensis was described by Distant (1905) based on two females ( Figs. 22 View FIGURE 22 A–D) from Kangding (Ta-chien-lu), Sichuan Province, China. However, examination of the type specimens of this species deposited in BMNH revealed that this species should be a member of Kosemia . In addition, Kosemia bifuscata ( Liu, 1940) (transferred from Leptopsalta by Sanborn (2013 )) is proposed here as a junior synonym of K. chinensis comb. n., based on their morphology and the same type locality. As mentioned above, we herein designate a female specimen (syntype in BMNH) ( Figs. 22 View FIGURE 22 A–B) as the lectotype and the other one also deposited in BMNH as the paralectotype ( Figs. 22 View FIGURE 22 C–D) of K. chinensis . In addition, we redescribe this species based on the male ( Figs. 20 View FIGURE 20 , 21 View FIGURE 21 ) for the first time.

This species can be easily distinguished from the other species of Kosemia by the following characteristics of males: lateral part of pronotal collar obviously ampliate laterally and slightly angled; fore wing with an infuscation at bases of the second and third apical cells, respectively; abdominal sternites almost black with posterior margins narrowly testaceous red; male clasper with a tiny spine at the median part of inner margin.
