Comments.

Polynema (Polynema) atrosimile is distributed in both mid-elevation Gongliu (1136 m) and lower-altitude Xinyuan (515 m). This species shares key morphological characteristics with the type species described by Soyka (1956), including: a scape longer than the pedicel; the third flagellomere equal in length to the pedicel; gaster ~ 2 × as long as wide; the longest marginal setae nearly equal to the wing width; and clava ~ 2 × as long as F 6. However, it differs in two critical aspects: the new species exhibits a forewing length-to-width ratio of 5: 1 (vs ~ 4.6: 1 in Soyka’s type specimen) and possesses a shorter mesosoma with a mesosoma-to-gaster ratio of about 0.9 (compared to ~ 0.7 in the latter).
