 Diagnosis. Males of T. solomona can be recognised by the long apical excisions of both, the tenth abdominal tergite and the subgenital plate, combined with curved, elongate cerci that are provided in subapical area with a rather large triangular expansion. The titillator is simple with a small curved spine at tip, it comes along with membranous folds that carry hairs along margin. Females have a plate-shaped subgenital plate with both halves obviously movable against each other along mid-length and with triangular ends; the basal-lateral extensions are simple and flat.   
 Description. Rather large for the genus. Tegmina surpassing middle of hind tibia. Femora with the following number of spines on ventral margins (paratype): fore femur 6 external, 5 internal; mid femur 6–7 external, 3 internal near base; hind femur 9–11 external, 12–15 internal. Femora with the following number of spines on ventral margins: fore femur 4–7 external, 2–6 internal; mid femur 5–7 external, 2–4 internal near base; hind femur 9–13 external, 10–18 internal.   
 Male. Stridulatory file with about 122–130 teeth. Tenth abdominal tergite terminating into two long projections that are slightly curved mediad and ventrad. Epiproct triangular. Paraprocts compressed with apical margin triangularly projecting and curved ventral-lateral, tip setose. Cerci long, distinctly surpassing projections of tenth abdominal tergite, curved in basal half, apical half almost straight, with a dorso-ventrally compressed, triangular, internal tooth at about beginning of apical third. Subgenital plate setose, apex with a narrow ovoid excision for more than a third the length of the subgenital plate; styli shorter than excised area. The titillators are widened around mid-length and carry at end a small curved spine. On both sides of the titillators there is a compressed membranous plate with hairs around margin. The basal-dorsal expansions are simply flat. They form, together with the margin of the plate, a wall around the basal-lateral projection of the ventral ovipositor valve.   
 Female. Tenth abdominal tergite furrowed and apex with a spiniform projection at both sides of midline. Subgenital plate in entire basal area furrowed and with a weak medial carina in the furrow; divided for the greatest part into two broad lobes widening in basal half, narrowing in apical half; internal margins straight except at apex and slightly overlapping in midline; apices of lobes rounded. Lateral areas roundly curved dorsad, roughly triangular, with a shallow furrow. Dorsal margin of ventral ovipositor valves at base with an elongate, setose projection pointing ventrad, roughly triangular with angle rounded, swollen in proximal, shallowly depressed in distal area. Eight abdominal tergite with lateral-posterior angles greatly excised and connected with lateral projections of subgenital plate by a wide membranous area. Subgenital plate and lateral areas of eight tergite strongly setose.   
 Coloration. Yellowish brown with patterns 0-1-4 or with all marks (0 to 4). hind femur with dorsal and apical areas stippled.
