A new genus and a new species of the tribe Haplotropidini Sergeev (Orthoptera: Acridoidea, Pamphagidae, Pamphaginae) with a key to the three genera of the tribe from China

This paper reports a new genus and a species of the tribe Haplotropidini Sergeev, 1995, i.e. Sulcohumpacris Yin, Yin et Cao gen. n. and Sulcohumpacris hebeiensis Yin, Yin et Cao sp. n. from Hebei Province, China. The new genus is similar to Humphaplotropis Xiao, Yin et Yin, 2013, but differs from the latter by the hump-formed pronotum along the median keel being deeply cut by hind sulcus and hence divided in two waves in lateral view, the anterior margin being acutely angular in the middle, the apex not reaching the hindmargin of the eyes, the frontal ridge being widened at the median ocellus, and the abdomen having large teeth along the median keel in lateral view. A key to the three genera of this Chinese tribe is given. The type specimens are deposited in the Museum of Hebei University, Baoding, China.
