Gorochovgryllacris
n. gen.
Diagnosis:
Medium size (
16–20 mm
) and body robust (
Figs. 67, 68, 72
). Head with a medium size and round ocellus, lateral ocelli as the first one, space between antennal cavities as wide as 1.5 times the wide of scape; fore coxa with a small and unarticulated spine, legs moderately long and robust, with four pairs of movable ventral spines on fore and middle tibiae; Hind femur with some ventral spines but with two conspicuous spines near the apex, one inner and other outer; hind tibia with few spines (three inner and four outer) little developed. Wings well developed, ovoid (
Fig. 69
) and little surpassing the abdomen apex (
Fig. 67
). Abdomen with traces of femoroabdominal apparatus; 9
th
abdominal tergite enlarged, hood shaped and with apex truncate; cerci simple, thin and short; 10
th
tergite totally covered by 9
th
tergite, rounded and with two little central hooks (
Figs. 70, 71
); subgenital plate gross, and with a pair of lateral styli, notch wide prolonged and up curved, apex rounded. Female subgenital plate rounded, ovipositor thin and approximately as long as hind femur (in the only known female the abdomen tip is poorly conserved).
Included species:
Type
species:
G. navicula
(
Brunner von Wattenwyl, 1888
)
n. comb.
(Before in
Brachybaenus
).
Etymology:
Dedicated to Andrej V. Gorochov as a recognition to his great contributions to raspy crickets and systematics of other
Ensifera
groups, plus typical termination—
gryllacris
common to genera of this family.
Comparison:
This new genus has a similar male terminalia structure as
Dinolarnaca deinura
Gorochov, 2008
,
Hyperbaenus griffini
Karny, 1932
and
H. fiebrigi
Giffini, 1908b (Hyperbaeninae)
.
Gorochovgryllacris
n. gen.
is closer with Gryllacridini genera than other taxa of this family; it differs from
Dinolarnaca
by its more robust build, well developed distal spines on ventral edge of the hind femora, and notch of the subgenital plate prolonged. Another genus with similar appearance of male terminalia is
Pardogryllacris
, but the new genus differs by the male apex abdomen of
Pardogryllacris
having a more enlarged 10
th
than 9
th
in contrast to
Gorochovgryllacris
n. gen.
, where the opposite occurs.
Distribution:

Guinea
