Two new species of the genus Kingdonella Uvarov, 1933 (Orthoptera, Acridoidea) and the first reported male of Kingdonellaqinghaiensis Zheng, 1990.

Abstract

Two new species of the genus Kingdonella and the first report of a male K.qinghaiensis Zheng, 1990 are presented. The new species K.gandensis sp. nov. has similar morphological features to K.wardi Uvarov, 1933, but it differs from the latter in having 1) the hind tibia black; 2) the epiproct, in males, with a median groove in the basal 1/2 and in the apical 1/4; 3) the denticles of the male epiproct black; 4) the outside of the hind femur reddish-brown on the basal 1/4 and black on the apical 3/4; and 5) the ventral face of the hind femur black on the outer side. The second new species, K.biruensis sp. nov., is morphologically close to K.pienbaensis Zheng, 1980 but differs from the latter in having 1) the length of the middle segment (12th segment) of antennae 1.2 times longer than its width; 2) the subgenital plate sharp-cornered in males; 3) the ovipositor smooth; 4) the upper half of hind femur outside surface with two black spots; and 5) the ventral face of the hind femur black on its outer side, red on the basal 2/3, and black on the apical 1/3 of its inner side. Finally, we provide a key to all known species of Kingdonella.
