32); venter of body with wide longitudinal greyish brown band on abdominal sternites, a pair of barely darkish areas on proximal half of genital plate, and numerous very small darkish dots on cerci ( Fig. 33 ). Eyes slightly higher than long; rostrum roundly angular in profile but with low and thin transverse keel at apex; maxillary palpi approximately as in Asymmetrella gen. n.; pronotum also similar to that of this genus but more strongly narrowing to head and with lateral keels slightly shorter and more sinuate in profile ( Figs 28, 31, 33 ); tegmina significantly protruding beyond abdominal apex and hind femora, with venation as in Figs 32–33 ; hind wings also significantly protruding beyond tegmina ( Fig. 32 ); fore and middle legs rather stout, with a pair of dorsal longitudinal keels on fore tibia ( Figs 31–33 ) having tympana as in Figs 29–30 (inner tympanum somewhat larger than outer one), with two keels on middle tibia (along dorsal and ventral tibial edges; Figs 32–33 ); hind leg more elongate and slender but also with more or less distinct dorsal keel on femur and a pair of dorsal longitudinal keels on tibia; spines and denticles of this tibia more or less similar to those of Asymmetrella gen. n.; genital plate elongately triangular and with almost spine-like but soft apical lobule; genitalia and spermatophore as in Figs 34–37 .

Female unknown.

Length in mm. Body 20.3; body with wings 29.5; pronotum 3.6; tegmina 21.5; hind femora 13.4.

COMPARISON. The new species differs from all the other congeners in the same characters as the subgenus Euzvenellomorpha subgen.n. (see the subgeneric key above).

ETYMOLOGY. This species name is the Latin word “carinata ” (carinate, with keels) due to the presence of characteristic keels on the lateral pronotal lobes.
