Diagnosis. Medium-sized. Body mostly greenish. Head yellowish, with brown markings on gena and lateral clypeus. Thorax with yellowish longitudinal stripe. Forewing with pterostigma pale; longitudinal veins pale; c-sc crossveins brown at base, but 2rd–4th brown totally; basal sc-r crossvein brown; radial crossveins brown; gradates crossveins brown; RP brown basally; psm-psc crossveins brown, green medially; CuA, CuP, A1 and A2 brown; MA and MP brown on intersections to longitudinal veins; im cell triangular, subdistally brown, connected by 1 rp-m crossvein to R; number of gradates crossveins (inner/outer): 3/6. Hindwing veins pale, but c-sc crossveins, distal r-rs crossveins and gradate crossveins brown, number of gradates crossveins (inner/outer): 3/6. Male genitalia with gonocornua short; entoprocessus long, curved; mediuncus separated from gonarcus, curved and acute apically ( Fig. 3 ).

There are eight species of Chrysopa recorded in or near Xinjiang, i.e., C. abbreviata Curtis, 1834 , C. altaica Hölzel, 1967 , C. formosa , C. hummeli Tjeder, 1936 , C. pallens (Rambur, 1838) , C. phyllochroma , and Chrysopa ( Euryloba) zhangi Yang, 1991 . Of which C. viridana can be easily distinguished of the first six by the unmarked frons and vertex, and distinguished from C. zhangi by the presence of genal and lateral stripes on gena, long, curved mediuncus and the elongate, curved entoprocessus in the male genitalia.

Material examined. 2♂, CHINA, Xinjiang, Turpan, Shanshan, Hongyuanzi ( IJKŦ), 43.1725°N, 90.1541°E , 1006.0 m, 22.VII.2023 (L), Zhichao Zhou, Zijun Liu, Huaiyu Liu ( CAU) .

Distribution. China ( Xinjiang), Central Asia, Middle East, Europe (widespread), northern Africa ( Oswald 2024).

Remarks. This species was originally described from Naples and is now known to be widespread in the western Palareactics and North Africa. It is recorded from China for the first time. The species has so for been founded only on broadleaf tree ( Bozdoðan 2020; Canard et al. 2010; Şengonca 1980), and considering the vegetation of the Tuha Basin, it is likely associated with Populus trees.
