2) Alloteratura (Meconemopsis) tuberculata Jin sp. n.

Holotype ♂ (both antennae and hind legs lost): NORTH BORNEO ( SE)/ Forest Camp , 19 km / N. of Kalabakan / 60m, 22.X.1962; K. J. Kuncheria / Collector / BISHOP

Paratype ♀ (both antennae broken, left middle and hind legs lost): BRITISH N. BORNEO/ Tawau, Quoin Hill / Cocoa Res. Sta. / 6.IX.1962; Y. Hirashima / Malaise Trap / BISHOP

Description. Medium size and typical appearence of the subgenus.

Fastigium of vertex bluntly conical with less distinct middle furrow, apex of fastigium darkened with a distinct reversed Y-shaped mark extended to middle of vertex ( Fig. 2b ). Apical segment of maxillary palpi extremely short, length about 1/4 of subapical one, its breadth longer than its length ( Fig. 2a ). Pronotum with deep lateral lobe, ventral margin rounded and projected slightly laterad, with distinct humeral sinus ( Fig. 2c ). Thoracic foramen large size. Tegmina and wings long, beyond end of hind femora. Fore coxal spur moderate long. Hind tibia with 3 pairs of apical spurs, apex of hind femur with spinule lobe, tip darkened.

Male 10 th tergite with shallow median notch, epiproct small semicircular lobe downwardly situated. Male cerci long lobe, more than half to basal part expended into broad lamina, distal less to half fine and curved upward at 1/2 ( Fig. 2d, e ). Subanal plate very short, invisible from outside. Subgenital plate with narrow distal part, slightly convex, 2 styli moderate long ( Fig. 2d ). Male genitalia not disected.

The 8 th abdominal tergite of female with an obvious poster ventral lobule projected backwards on each side ( Fig. 2a, f ). Subgenital plate short trapezoid with posterior margin slightly concave in middle. Ovipositor rather thick and short, dorsal and ventral valve equals in length, ventral valve with fine denticulate in distal part ( Fig. 2a ).

Measurements (mm). Body: ♂ 7.7, ♀ 8.2; Pronotum: ♂ 4.8, ♀ 3.3; Tegmina: ♂ 11.8, ♀ 15.2; Hind femora: ♀ 8.7; Ovipositor: 5.5.

Comparison. This species is very similar to Alloteratura (Meconemopsis) breviuscula Gorochov, 2016 (Figs. 55–58) from Tawau, Borneo, by male cerci in long lobe with distal lamina, but subgenital plate with smooth posterior margin.

Etymology. Species name refers to a pair of projected lobules on the 8 th abdominal tergite of female.
