Description.
Medium sized to large species. Head: Face ovoid; forehead nearly smooth; fastigium verticis wider than scapus; ocelli distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows very shallow (
Fig. 48K
). Abdominal tergites two and three without stridulatory pegs.
Wings surpassing middle of stretched hind tibiae (
Fig. 47F
). Tegmen: Radius forked near tip; media anterior at very base free, then it closely approaches or sub-fuses for about
5 mm
with radius, after both veins separated again media receives a short oblique connection vein from radius (probably RS), in apical third of tegmen MA separates from the fused MA+RS vein as an oblique posterior branch while RS terminates into three posterior branches; cubitus anterior at base single-branched and distinctly thickened, it divides at end of basal third, the first branch in a curvature and then divides into MP and CuA1; CuA2 remains single branched. Cubitus posterior undivided, free throughout; with 4 anal veins.
Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with about 6–7 external and about 12–14 internal spines on ventral margins getting distinctly larger towards end; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.
Coloration. General color medium brown with indistinct ornament; rim of pronotum red brown. Face yellowish brown; antennal scrobae, a wide vertical band below compound eyes, margins of clypeus and labrum and maxillary palpi dark brown. Tegmen semi-transparent yellowish, towards base darker; veins medium to dark brown; hind wing dark red brown, towards hind margin lighter and cells with yellowish spot in middle; main veins black to brown; cross veins medium brown to yellowish.
Male. Eighth abdominal tergite with dorsal area prolonged, not laterally. Ninth abdominal tergite with a strong medial furrow, globular on both sides; semi-globes at ventro-internal angle compressed and prolonged into a large compressed triangular process pointing about mediad; process at base yellowish, afterwards dark brown with black margin (
Figs. 50
F–G). Epiproct small triangular. Subgenital plate wider than long with a large triangular excision from base, lateral margins convex and converging, apical margin wide roundly excised, with a shallow furrow in midline between apical and basal excisions; cerci little upcurved, longer than subgenital plate, inserted at wide trunks that occupy all of the non-excised apical margin. Phallus membranous.
Measurements (

).—body w/wings: 51; body w/o wings: 29; pronotum: 6.5; tegmen: 42; tegmen width: 12; hind femur: 18; antenna:
85 mm
.
Discussion.
Habitus and wing venation agree with the type of
Capnogryllacris (C.) elongata
(
Fritze, 1908
)
, except that MA is fused with R in subbasal area instead of only leaning on R but not fused as in the type; basic color of hind wings is dark reddish brown instead of more yellowish brown in the type. Also in the
holotype
there is a short oblique connection branch from R to MA (fusion of RS with M) although it is missing in the drawing that came with the original description by Fritze in
Carl (1908)
. The shape of the male ninth abdominal tergite and its processes agree with the descriptions in Fritze in
Carl (1908)
and
Griffini (1911d)
.
