(2021: 236) (catalogue, distribution); Zhou et al. (2022: 366) (redescription, distribution, figure). Holotype ( ♂): China, Zhejiang, Moganshan, CAU.

Type material examined. Holotype. CHINA: ♂, Zhejiang, Deqing, Moganshan , 1991.v.12, Yonghua Wang leg. ( CAU) . Paratypes. CHINA: 1♀, same locality as for holotype, 1991.iv.24, Haoxin Lou leg. ( CAU) . 1♀, same locality and collector as for preceding, 1991.iv.30 ( CAU) . 1♂ 6♀♀, Zhejiang, Lin’an, Xitianmushan , 1980.v.4–5, Chikun Yang leg. ( CAU) .

Diagnosis. Generally shining blackish brown; face, parafacial and gena yellow; antennal arista bicolorous, with yellow basal half and dark brown apical half; postpronotum and propleuron yellow; mesonotum black, with pair of yellow lateral markings on posterior half; wing slightly infumate, with large dark suffusion at apex and vague broad median transverse band interrupted along cell r 1; legs mostly yellow, with mid and hind femora narrowly dark brown subapically, mid and hind tibiae largely dark brown.

Distribution. China ( Sichuan, Zhejiang).

Remarks. This species was originally described based on a male holotype and two female paratypes (including one treated as “ allotype ”) from Moganshan, Zhejiang, China, and seven paratypes ( one male and six females) from Xitianmushan, Zhejiang, China ( Yang & Wang 1992). The type material of this species was presumed to be lost prior to this study except one paratype could be found ( Evenhuis 2016; Galinskaya & Shatalkin 2016). During the present study, the holotype and all nine paratypes were found in the collection of CAU. Images of the holotype ( Fig. 1 ) and the paratype which was originally referred as “ allotype ” ( Fig. 2 ) are provided herein.

Galinskaya & Shatalkin (2018) redescribed this species based on a male specimen from Baoxing, Sichuan, China. An illustration of the male genitalia of this species was provided in its original description and was copied by Yang & Wang (1998), Xi et al. (2016), and Zhou et al. (2022).
