Note. Volynkin & Saldaitis (2020) erroneously attributed the authorship of the species to Martin Hering whereas the latter is in fact indicated as an author of only the genus Parabitecta (see Draeseke 1926: 50) while the new species is described without an authorship being specified, which by default attributes the authorship of the taxon to the author of the article, vic. Johannes Draeseke. This also corresponds to the authorship of the species indicated on the labels of the holotype.

Diagnosis. The forewing length is 19.0–20.0 mm in males and 21.0–22.0 mm in females. Parabitecta flava is reminiscent of P. secunda but can be easily distinguished by its ochreous yellow body and wing coloration, which is brown in P. secunda . Compared to P. secunda , the male genitalia of P. flava have a slightly narrower uncus, a smaller juxta, a shorter distal spine of the distal saccular process, which is situated subapically (vs. apical position in P. secunda ), a somewhat narrower phallus, and a vestigial lateral cornutus in the phallus vesica, which is well-developed in P. secunda . The female genitalia of P. flava differ from P. secunda in the considerably smaller pocket-like antevaginal plate, the somewhat narrower ductus bursae, the narrower gelatinous enlargement of the posterior section of the corpus bursae, and the slightly narrower appendix bursae.

Distribution. The species is widespread in China (Sichuan, Yunnan, Shaanxi, Zhejiang, Fujian, and Hubei Provinces) ( Draeseke 1926; Daniel 1954; Fang 2000; Volynkin & Saldaitis 2020).
