Etymology. The species name is named after the collector. The gender is feminine.

Description of male. Head ( Fig. 1 A–C) about as wide as pronotum. Generally black without distinct markings. Eyes brown, ocelli dark brown. Supra-antennal plates orange-yellow. Postclypeus orange-yellow, with longitudinal central fasciae black; series of 7–8 transverse fasciae black. Anteclypeus black. Rostrum with black apex extending to mid trochanter. Genae black, with dense, long silvery hairs. Distance between lateral ocellus and corresponding eye slightly wider than distance between lateral ocelli.

Thorax ( Fig. 1 A–C). Pronotum almost black, with anterior margin yellow; a central yellow fasciae, extending from anterior margin of pronotum, broadened at posterior end; pair of faint yellow spots near anterior margin of pronotum; pronotal collar yellow with posterior margin rippled. Mesonotum black, without distinct markings. Cruciform elevation yellow, with anterior and posterior angles black. Thoracic sternites black, with dense, long silvery hairs.

Legs ( Fig. 1 E). Black with orange-yellow patches. Fore femur with only two spines, secondary spine erect and subapical spine curved.

Wings ( Fig. 1 A, B). Hyaline, veins ochraceous. Fore wing with distinct, continuous infuscations at bases of apical cells 1–7 and proximal portion of apical cell 1. Hind wing with distinct, continuous infuscation at bases of apical cells 1–5; proximal portions of cubital cell 2 and anal cell 1 tinged with light brown.

Abdomen ( Fig. 1 A, B, D). Black, with white pollinosity fasciae between tergites VI and VII. Timbal covers black, short and rounded, incomplete but concealing timbals mostly; timbals with ten long ribs. Opercula ocherous, covered with silvery hairs; with rounded apex not extending beyond posterior margin of sternite II. Abdominal sternites mostly black, covered with dense silvery hairs.

Genitalia ( Fig. 1 F–H). Pygofer rounded in ventral view, with dense, long silvery hairs. Dorsal beak long. Upper lobes of pygofer well developed, very long and pointed. Basal lobes of pygofer widened basically, and slightly pointed apically. Uncus short, pair of median clasper processes separated basally. Aedeagus with basal part broadened; apex with three sclerotized processes and two folded saccate hooks.

Description of female ( Fig. 2 ). Opercula scarcely developed. Abdominal segment 7 with posterior margin incised at middle. Abdominal segment 9 black, with yellow median marking in ventral view. Ovipositor sheath black, extending beyond abdominal segment 9. Other characteristics similar to male.

Habitat. The adult emergence of this new species gets started from late September and lasts to December, which is much later than that of most other cicadas occurring in Sichuan Province. Most individuals were observed sitting and singing on Zill Mango trees ( Mangifera indica L.), but also on some other plants such as Dodonaea viscosa (L.) Jacq. and Sorghum bicolor (L.) Moench ( Fig. 3 ).

Distribution. China (Sichuan).

Remarks. This new species is similar to C. gregoryi , but can be distinguished by the following characters: white pollinosity fasciae between tergites VI and VII of abdomen, continuous infuscation at bases of apical cells 1– 7 of fore wing, the broad infuscation on apical cells 1–5 of hind wing, the two spines of fore femur, and the developed basal lobes of pygofer.
