In this paper, 2 new species, Macromotettix nanshana sp. nov. and Coptotettix guangxiensis sp. nov. of Tetrigidae (Orthoptera) are described from China. Type specimens were deposited at the Institute of Entomology, Sun Yat-sen University, and College of Life Sciences, Nanjing Normal University, China.

The family Tetrigidae belongs to Tetrigoidea of the order Orthoptera. The family has been divided into nine subfamilies: Batrachideinae, Cladonotinae, Cleostratinae, Discotettiginae, Lophotettiginae, Metrodorinae, Scelimeninae, Tetriginae, and Tripetalocerinae (Eades et al. 2013). The genus Macromotettix, a member of the subfamily Metrodorinae, was erected by Günther in 1939. To date, there are 24 known Macromotettix species (Günther, K. 1973; Jiang & Zheng 1998; Liang &Zheng 1998; Zheng & Jiang 2002a, 2003; Zheng & Ou 2003; Zheng 2005; Deng et al. 2007a, 2007b ; Zheng et al. 2009a, 2009b; Zheng & Ou 2010; Deng et al. 2010; Zheng et al. 2012; Eades et al. 2013) . Also the genus Coptotettix within the subfamily Tetriginae was erected by Bolívar in 1887, and it includes 71 known species (Zheng et al. 2013 and the references therein) in the world.

This article presents 2 new species, Macromotettix nanshanensis Liang & Jiang sp. nov. and Coptotettix guangxiensis Jiang & Liang sp. nov. All types are deposited at the College of Life Sciences, Nanjing Normal University (Nanjing), and Institute of Entomology, Sun Yat-sen University (Guangzhou), China.

Material and Methods

In Jul and Aug 2006, we investigated insects in the Fangcheng Golden Camellia National Nature Reserve of Guangxi (Forestry Department of Guangxi 1993), located in Fangchenggang City of Guangxi Zhuang Autonomous Region, China. Among the specimens collected, 2 new species of Tetrigoidea were found. The new species described were collected by net sweeping during the day, along edges of streams and roads within the Nature Reserve.

In the descriptions below the following conventions were adopted for specimen measurements: body length: the distance from apex of fastigium verticis to posterior margin of tenth abdominal tergite; tegmen: the visible distance from base of tegmen to the apex in lateral vew; hind femur: the distance from base of hind femur to the apex of genicular or kneelobe. Measurements of specimens were in millimeters (mm).

The taxonomic system of Eades et al. (2013) was adopted here.

  • Diagnosis

    This new species is similar to Macromotettix longtanensis (Zheng & Jiang 2003) and M. wuliangshana (Zheng & Ou 2003), but differs in the following characteristics: 1) upper margins of antennal fossa and lower margins of eyes at the same horizontal line; 2) in profile, median carinae of the pronotum arched between transverse sulci and humeral angles; 3) hind process of the pronotum slightly exceeding top of hind femur; 4) lateral carinae constricted backward on the prozona; 5) disc of the pronotum without short longitudinal carinae; 6) ventro-cephalad angle of lateral lobes of the pronotum circular arc; 7) wings slightly exceeding the apex of hind process of pronotum; 8) basal half of the dorsal median carinae of pronotum smooth, the other half with fine teeth. Because no males of M. longtanensis or M. wuliangshana were available for study, only the female characters above were compared.
