Humphaplotropis hebeiensis sp. nov.

( Figs. 9–15 )

Male ( Figs. 9–13 ). Body large in size. Head shorter than length of pronotum. Face slightly oblique in profile, frontal ridge with longitudinal sulcus, both lateral carinae parallel, short, not reaching the clypeus. Antennae filiform, 22 segments, not reaching the posterior margin of pronotum. Eyes globose, vertical diameter 1.3 times horizontal diameter and 1.4 times subocular furrow. Pronotum lower hump along the median keel, the high upper than vertex occupied 1/5 of whole high of pronotum in lateral view; anterior margin acute angular in the middle, the apex reaching the hind margin of eyes, posterior margin acute angular in the middle, the apex reaching the middle point of first abdominal terga; median keel not cut by hind transverse sulcus; lateral keels developed. Prosternum collar-like with a thin edge, without tubercles or lobes. Tegmina shortened, oval, lateral, extending over the hind margin of first abdominal tergum, cover 4/5 tympanum. Middle tibia without teeth or tubercles. Hind femur robust, length as long as 3.9 times of maximum width, lower basal lobe longer than the upper one, upper keel smooth, the end of lower knee lobes rounded. Hind tibia with 9 spines on the inner side and 10 spines on outer side, external apical spine present. Tympanum organ distinct, big and rotundity. Krauss’ organ washboard-like. Epiproct with longitudinal groove in the middle. Cercus conical, almost reaching the tip of epiproct. Subgenital plate triangle, apex acute. Epiphallus with 44 spikes, ancorae oblique inward distinctly, both posterior projections shorter than median projection distinctly.

Female ( Figs. 14–15 ). Body larger than male. Eyes small, longitudinal diameter almost equal subocular furrow. Tegmina shorter, reaching the hind margin of first abdominal tergum. Subgenital plate width larger than length

Body yellowish-brown. Eyes brown. Antennae yellowish-brown, apical part dark. Hind femur yellowishbrown. Hind tibia and tarsus yellowish-brown. Abdomen yellowish-brown, with a light dark band on the both sides. Subgenital plate brown.

Holotype: ♂, Hebei Xingtai (36°02'N, 117°13'E), China, collected by Li Xin-Jiang and Zhi Yong-Chao, 9 June, 2014. paratype 1 ♀, Hebei Xingtai (36°02'N, 117°13'E), China, collected by Li Xin-Jiang and Zhi Yong-Chao, 3 July, 2014.

The new species is allied to H. culaishanensis Li, Cao et Yin, 2014 . The major differences are listed in Table 1 .

Etymology. The specific epithet is named for Hebei the type locality.
