Capnia dusmeti Navás, 1917 — Navás 1917: 396. (original description of the adult).

Capnia bifrons (Newman, 1838) — Aubert 1952: 247. (synonymy of Capnia dusmeti Navás, 1917 with Capnia bifrons (Newman, 1838)) .

This species was described on the basis of a female from Spain. The type specimen is lost, however, it was synonymized with Z. bifrons on the basis of the original description (Aubert 1952). As the drumming signals of

several Iberian populations differ from that of Z. bifrons (Rupprecht 1997), their conspecifity cannot be confirmed. Capnia dusmeti is regarded as a nomen dubium instead of a junior synonym of Z. bifrons .
