A taxonomic review of Longchuanacris Zheng et Fu (Orthoptera: Acrididae: Catantopinae), with descriptions of two new species from Yunnan, China Author Mao, Ben-Yong Author Ren, Guo-Dong Author Ou, Xiao-Hong text Zootaxa 2007 1467 51 62 journal article 10.5281/zenodo.176617 fda05e21-3bb4-4b96-8fa9-e00273f96325 1175-5326 176617 Longchuanacris viridus Mao et Ou , comb. nov. , nomen nov. ( Figs 11–21 , 53–54 ) Caryanda macrofurcula Mao et Ou, 2000 : 182 –184, figs 1–4. Material examined CHINA : Yunnan: 21 males and 12 females ( paratypes , CLDU ), Tengchong County, 25º0’ N , 98º30’ E , 1750m , 25 Jul. 1999 , collected by Ben-yong Mao ( CLDU ), Ji-shan Xu ( CLDU ) and Zi-Zhong Yang ( CLDU ). 3 males and 1 females ( paratypes , CLDU ), Baoshan, 25º6’ N , 99º6’ E , 1750m , 26 Jul. 1999 , collected by Benyong Mao ( CLDU ). 1 males ( paratypes , CLDU ), Dali, 25º30’ N , 100º18’ E , 1970m , 2 Aug. 1999 , collected by Zi-Zhong Yang ( CLDU ). FIGURES 11–21. Longchuanacris viridus Mao et Ou. 11. male head and pronotum, dorsal view; 12. male mesosternum and metasternum; 13–14. male terminalia, dorsal and lateral views; 15. female subgenital plate, ventral view; 16–18. epiphallus, dorsal, anterior and lateral views; 19–21. phallic complex, anterior, lateral and dorsal views. Scale bars = 1mm. Description Male ( Figs 11–21 ). The main morphological characters of the species are illustrated ( Figs 11–15 ), and the phallic complex is newly described here. Epiphallus with crescent outer lophi nearly projecting in a 90° angle from bridge and rounded inner lophi; anchorae with apex obtuse; anterior projections with posterior sides nearly straight in lateral view; lateral plate with external margin concave in dorsal view and posterior sides convex in lateral view; posterior projection somewhat stout and backward reaching at posterior margin of outer lophi in lateral view; bridge distinctly divided in middle (figs 16–18). Phallic complex illustrated (figs 19–21). Ectophallic membrane with an extra, spoon-shaped sclerite (fig. 20). Remarks Sharing the same generic characters with other four, especially on male furculae upright large and lophi crescent, the species is transferred to Longchuanacris from Caryanda . A new scientific name of L. viridus Mao et Ou is given for C. macrofurcula Mao et Ou, 2000 to avoid a junior homonym of type species L. macrofurculus Zheng et Fu, 1989 . Distribution China : Yunnan (Tengchong, Baoshan, Dali).
