Formica liopthalma

Seifert & Schultz (2021) found that while the description of this species clearly indicates it belongs to the subgenus Coptoformica, it does not allow a species-level identification. The material investigated during their revision indicated four species to occur in Gansu (the type locality of F. liopthalma): the Beishan morph of Formica exsecta, Formica pisarskii, Formica manchu and Formica brunneonitida. The very rough, unskilled description of Chang & He, mentioning “hairs very sparse” and a weakly notched petiolar crest, could possibly indicate a synonymy with F. brunneonitida but this remains a speculation.

Identification
Chang and He (2002) - Similar to Formica longiceps, but F. liopthalma lacking pubescence on both eye faces; upper 1/3 of petiole node bent forward; posterior half of head dorsum black; hairs very sparse.
