Pachynematus imperfectus var. claristernis Enslin, 1916a: 484 . Lectotype designated below. Synonymy by Taeger et al. (2010).

Pachynematus (Larinematus) tatricus Roller & Haris, 2008: 47–49 . Syn. nov.

Diagnosis

Small subapical tooth of claws, colouration (male largely black; in female, pterostigma basally paler than apically, abdomen dorsally black, metafemur at least partly pale), structure of valvula 3 (in dorsal view rather broad, not tapering, and posteriorly with invagination) and penis valve enable separation of the species from the other Euura . The shape of valvula 3 varies somewhat, but there is no clear gap in variability and apparently no correlation with variability in mesepisternum colouration (from completely black to completely pale).
