Abstract:
5 families, 19 genera and 36 species of Tetrigoidea from Hunan province are recorded in the present study, among them three species are new to science, i.e. Mazarredia hupingshanensis sp. nov., Mazarredia hunanensis sp. nov. and Aalatettix hupingshanensis sp. nov.Mazarredia hupingshanensis sp. nov. is allied to Mazarredia convexa Deng, Zheng & Wei, 2007, but differs in: 1) width of frontal ridge which between antennae is wider than that of first segment of antenna; 2) upper margin of pronotum with slightly wave-like in profile; 3) hind process of pronotum reaching the top of hind femur; 4) lower margin of midfemur straight; 5) lower outer side of hind femur with no black; 6) hind tibia with brown. Length of body: ♂6 mm; length of pronotum: ♂6 mm; length of hind femur: ♂5 mm.Holotype ♂, Hunan: Shimen(Hupingshan), 17-Sept.-2004, collected by Wang Ji-Liang.Mazarredia hunanensis sp. nov. is allied to Mazarredia platynota Zheng et Ou, 2010, but differs in: 1) vertex and frontal ridge forming an obtuse rounded in profile; 2) frontal ridge slightly concave before lateral oculus in profile; 3) lateral oculus being in the middle of the anterior margin of eyes; 4) upper margin of pronotum slightly wave-like before shoulders and straight behind it in profile; 5)width of midfemur is narrower than the width of tegmina; 6) lower outer side of hind femur with no black; 7) hind tibia brown.Length of body: ♀9 mm; length of pronotum: ♀10 mm; length of hind femur: ♀5.2 mm.Holotype ♀, Hunan: Yuangling, 1-Sept.-2004, collected by Wang Ji-Liang.Aalatettix hupingshanensis sp. nov. is allied to Aalatettix leshanensis Zheng, Cao & Chen, 2011 and Aalatettix cangshanensis Zheng, Lin & Zhang, 2013. It differs from both in: 1) vertex and frontal ridge forming a rounded in profile; 2)upper margin of pronotum nearly straight in profile; 3)hind process of pronotum reaching knee of hind femur. The new species also differs from A.cangshanensis in: 1) vertex protruding before the anterior margin of eyes in dorsal view; 2) lower margin of midfemur with wave-like structure. The new species also differs from A.leshanensis in the width of frontal ridge which between antennae is larger than that of first segment of antenna.Length of body: ♂10 mm; length of pronotum: ♂8.8 mm; length of hind femur: ♂5.5 mm.Holotype ♂, Hunan: Shimen(Hupingshan), 17-Sept.-2004, collected by Wang Ji-Liang.
