3) Alloteratura (Meconemopsis) kevani Jin sp. n.

Holotype ♀ (both antennae, left fore and middle legs, right hind leg lost): BRITISH N. BORNEO/ Tawau, Quoin Hill / 15–20.VII.1962; H. Holtmann / Light Trap / BISHOP

Diagnosis. General appearance very similar to Alloteratura (M.) tuberculata Jin sp. n. Apex of fastigium darkened with a distinct reversed Y-shaped mark extended to middle of vertex ( Fig. 3b ). Humeral sinus distinct, cross point of lateral plate to pronotum disc in right angle ( Fig. 3c ). Thoracic foramen large size. Tegmina and wings long, beyond apex of hind femora. Fore coxal spur moderate long. Hind tibia with 3 pairs of apical spurs, apex of hind femur with spinule lobe.

Female subgenital plate relatively short, with almost even posterior margin ( Fig. 3d ). Ovipositor relatively slender and long with pointed apex, ventral valve shorter than dorsal one ( Fig. 3a ).

Male unknown.

Measurements (mm). Body: ♀ 8.9; Pronotum: ♀ 3.2; Tegmina: ♀ 13.2; Hind femora: ♀ 9.1; Ovipositor: 6.3.

Comparison: These 2 characters, that is, a reversed Y-shaped darkened mark from apex of fastigium extended to middle of vertex, and the 8 th tergite without a posteroventral lobules projected backwards on each side, make this female very similar to Alloteratura (Meconemopsis) sarawaki Gorochov, 2016 (Fig. 34–36, 51, 63, 64) from Borneo, but humeral sinus in right angle, subgenital plate with more or less even posterior margin, without posteromedian notch, ovipositor not equal in length, ventral valve distinctly shorter than dorsal one.

Etymology. Species is named in honor of Canadian Orthopterist, Dr. Douglas Keath McE Kevan, Ph.D. thesis supervisor of the first author.
