1) Alloteratura (Meconemopsis) kalabakanica Jin sp. n.

Holotype ♂: NORTH BORNEO ( SE)/ Forest camp, 19 km / N. of Kalabakan / 18.X. 1962; Y. Hirashima / Collector / BISHOP

Paratype ♀: same label data as Holotype .

Description. Medium size and typical appearance of the subgenus.

Fastigium of vertex bluntly conical with less distinct middle furrow ( Fig. 1c ). Apical segment of maxillary palpi extremely short, its length about 1/4 of subapical one, no longer than its breadth ( Fig. 1d ). Pronotum with very deep lateral lobe, ventral margin rounded and projected slightly backward, with distinct humeral sinus ( Fig. 1a, b ). Thorasic foramen large size. Tegmina and wings long, beyond apex of hind femora. Fore coxal spur comparatively long. Hind tibia with 3 pairs of apical spurs, apex of femur with spinule lobule ( Fig. 1h ).

Male last tergite with even posterior margin, epiproct small semicircular lobe downward situated. Male cerci long and simple lobe, median part expanded inwardly into lamina, apical half tapering, curved upward at 1/3 of base ( Fig. 1e ). Subanal plate very short, invisible from outside. Subgenital plate quite short with round and smooth posterior margin, 2 styli comparatively long and located close to each other ( Fig. 1e, f ). Male genitalia less chitinized epiphallus covered with denticules ( Fig. 1g ).

Female subgenital plate with sharp posteriomedian notch ( Fig. 1i ). Ovipositor slender and long with acute apex ( Fig. 1b ).

Measurements (mm). Body: ♂ 9.3, ♀ 9.7; Pronotum: ♂ 4.1, ♀ 4.0; Tegmina: ♂ 15.9, ♀ 18.1; Hind femora: ♂ 10.0; Ovipositor: 8.9.

Comparison. This species is close to Alloteratura (Meconemopsis) longa Gorochov, 2008 (Figs. 57–63) from North Borneo by the shape of slender male cerci with smooth acute apex, but differs in male cerci expended in basal rather than in middle part; male subgenital plate with 2 styli very close to each other; female subgenital plate with sharp posterior median notch.

Etymology. Species name refers to the type locality Kalabakan of North Borneo.
