Cohnia equatorialis (Giglio-Tos 1898) comb. nov.

Isophya equatorialis Giglio-Tos 1898

Anisophya equatorialis (Giglio-Tos 1898)

The male type specimen was collected on the eastern cordillera of the Andes in Ecuador, Provincia Azuay, Gualaceo, 2300 m. No further records of this species seem to be known. Along with the few other neotropical Isophya species it was recently transferred to Anisophya Karabag 1960 ( Braun 2010) , but comparing it to the syntypes of the type species A. hamata (photos in OSF) and a male specimen of A. brasilienis (collected in December 2010 at the “Laguna de los Patos” near La Plata, Provincia Buenos Aires, Argentina), it actually fits much better in the new genus Cohnia . Real Anisophya species have a broad fastigium which is contiguous with the frons, while it is very narrow in C. equatorialis , and developed as “a small, bluntly conical projection” ( Hebard 1924). On the tegmina in Cohnia , which are somewhat longer than the pronotum in C. equatorialis , the subcostal and radial veins are very close to each other (the space between them being about as wide as or narrower than the diameter of one vein), whereas in Anisophya they are well separated. Finally the cerci of Cohnia are simple and uniformly curved and tapering, and not dorso-ventrally flattened with distinctly offset apical portion or spine as in Anisophya .
