Sinoperla nigroflavata – Illies 1966: 274 (catalog).

Chinoperla nigroflavata – Zwick 1980: 130 (transferred from Sinoperla). — Zwick 1982: 167 (synopsis). — Sivec et al. 1988: 54 (synopsis). — Du et al. 1999: 62 (catalog). — Yang & Li 2018: 36 (catalog).

Distribution

China: Fujian Province, known only from the (now lost) holotype.

Remarks

The details of the aedeagal structures of this species are still unknown and the type material is lost (Wu 1948; Du et al. 1999; Yang & Li 2018). No new material was available for the present study, but it seems to differ from the remaining Chinese species of Chinoperla based on the absence of the short Sc of the forewing and the shape of the dark median sclerite of tergum 9 (Wu 1948: figs 8–9). Chinoperla gorohovi Sivec & Stark, 2010 from Guangdong and Vietnam is easily distinguishable from C. nigroflavata by the slender nail-shaped median sclerite with a slightly enlarged apex (Fig. 11B–D).
