Type species :Ca ri nodelphax ca ri nat us Ding et Yang ,1987.
The Chinese planthopper genus Ca ri nodelphax Ding et Yang ,p reviously known f rom a single female of its type species , C.ca ri nat us Ding et Yang ,is re 2viewed.One new species , C.hai na nensis sp.nov.is described and a key to separate the two species is gi 2ven.Details of the male genitalia are given f or the first time together with a description of other characters.Type specimens are deposited in the Northwest A &F U niversity (N WSUAF ).
The genus is redescribed as f ollows.
Head including eyes narrower than p ronotum.Vertex at base broader than length in middle http://m.wendangku.net/doc/9d814b6758fafab069dc02ad.html 2teral carina distinctly keeled and slightly convergent distad ,Y 2carina with stalk absent.Frons in middle line longer than wide at widest part about 214∶110,lateral carina distinctly keeled and nearly straight ,median carina simple ,postclypeus with the same width at base as f rons at apex ,in p rofile postclypeus at an obtuse angle to anteclypeus.Rostrum reaching over meso 2trochanters.Antennae with the basal seg 2ment longer or slightly longer than wide ,shorter than second ,two segments together reaching or not reaching to f rontoclypeal suture.Pro 2and mesonotum with carina well developed.Tegmina with basal half of hind margin of clavus elevated ,all veins speckled.Tibial sp ur with a tooth at apex ,without teeth on hind margin ,spinal f ormula of hind leg 52624.
Anal segment of male collar 2shaped ,lateroapical angles not p roduced.Pygofer in posterior view with
opening longer than wide ,lateral margins strongly in 2cised resulting f rom the basal part being greatly p ro 2duced ,lateral margins in p rofle with “V ”2shaped in 2cision ,without medioventral p rocess.Aedeagus with p hallobase ,p hallus tubular ,simple.Genital style long ,robust.
This genus belongs to the tribe Tropidocep halini ,and is allied to Acrof acies Muir ,1915.It can be dis 2tinguished f rom the latter by :1)f rons with the widest part apically ;2)postclypeus in p rofile at an obtuse angle to anteclypeus ;3)aedeagus with p hallobase ;4)p ygofer with lateral margins strongly incised f rom posterior view ,with “V ”2shaped incision in p rofile.

Macropt.Length of body ♂118mm ;tegmen ♂216mm.
General colour brown ,a longitudinal pale yel 2lowish stripe f rom apex of postclypeus to end of scutel 2lum borded with blackish brown ,lateral carina of
gena additionally with a pale yellowish stripe.Anten 2nae with rings around middle and apex of first seg 2ment ,and the base of second segment ,blackish brown;apex of second segment brown.Pro 2and mesonotum with areas around inner and outer lateral carina ,apex of tegula and abdomen ,blackish brown ;anal segment yellowish brown.
Vertex wider at base than long submedially about 114∶110,submedian carina p resent subapically.Frons longer in middle line than wide at widest part about 214∶110,widest at apex.Antennae surpassing f rontoclypeal suture ,basal segment longer than wide about 114∶110,shorter than the second about 110∶114.
Male p ygofer with opening longer than wide in posterior view ,in p rofile ,broader ventrally than dorsally.Aedeagus with p hallobase ,p hallus simple ,
slender ,pointed at apex ,p hallobase broad at base ,rounded at apex in lateral view ,with a lobe 2like p ro 2cess on dorsal margin subbasally.Genital style parallel in posterior view ,flattened in lateral view ,tapering f rom base to apex ,apex curved ,hook 2shaped.
The new species can be distinguished f rom Ca ri n 2odelphax ca ri nat us Ding et Yang by :1)antennae with two segments together surpassing f rontoclypeal suture ,the second segment about 114times the length of first ;2)first segment of antennae with a blackish brown ring at midlength and apex of second segment brown ;3)tibia and tarsi without dark brown annular marks.
