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
.
