This paper deals with a new genus, and two new species of the Gryllidae from Ch ina. Type specimens of Capillogryllus dolabripalpis are deposited in the Wu han Polyt echnic University, Wuhan, China and the type specimens of C.exilipalp is are d eposited in the Institute of Entomology, Zhongshan University, Guangzhou, China.Capillogryllus Xie, gen.nov. Type species: Capillogryllus dolabripalpis Xie et Zheng, sp.nov. Size small, body depressed, very pubescent, both sides of body with dense cilife rous and bristles. Dorsal surface of body black and ventral surface yellow-brow n or black-brown. Vertex black shinning, strong inclinate; eyes large, yellow -brown or grey-brown, adorned with black spots; ocelli arranged in a triangle; antennae brown, very pubescent;frons and genal area below eyes black-red; cl ypeus and labrum red-brown, adorned with black spots; maxillary and labial palp i uniform in colour, yellow-brown or black-brown. Prothorax posteriorly co nstr icted; median longitudinal sulcus of pronotum obvious, dorsocentral region conc avo-conve x, smooth, shinning; anterior and posterior margin of prothorax with a row of b ristles; inferior margin of pleurite slightly ascending posteriorly. Mesothorax shorter and narrower than metathorax. ♂, apterous; ♀,only a p air of anterior m icropterous wings, not extending beyond the posterior margin of mesonotum. Legs pubescent, sparsely bristled; anterior tibiae absent from tympana; posterior tib ia arme d with 4 dorsal spurs on each margin and 6 apical spurs; posterior basitarsus ar med with 6 external and 3-5 internal denticles. ♂,genitalia: epiphallus roughly H-shaped in dorsal aspect, the short dorsal bridge formed by the emargination of the anterior and posterior margins, being roughly one the fifth as long a s the depth of the anterior emargination and one the third the depth of the post erior emargination; median portion of the posterior margin entire, with no media n lobes; dorso-posterior apices of the posterior processes of the epiphallus p r oduced bifarious triangular lobes; ectoparameres roughly dumbbell-shaped; mesal lobes well developed and not fused along the median line; endoparameres roughly C-shaped in ventral aspect; virga short and not passing posterior margin of epi p hallus; rami straight, having two transverse arms: one connected with endoparame res and another extend to epiphallus. ♀,ovipositor sword-shaped, strongly upwa rds curved. This new genus is similar to Cophogryllus Saussure 1877, but differs from: 1 ) ♂,epiphallus H-shaped; 2) ♂, virga short; 3) b ody armed with dense bristles; 4)♀,ovipositor strongly upwards curved.Capillogryllus dolabripalpis Xie et Zheng, sp.nov.(Figs.1-7) Dorsal surface of body ink black and ventral surface black-brown; eyes yellow- br own, adorned with black spots; the apical segment of maxillary and labial palpi axe-shaped, the longest, and the third segment longer than the fourth one; the p osterior margin of ventral plate of mesothorax concave; ♂, apt erous; ♀, only a pair of anterior micropterous wings, not extending beyond the posterior margin of mesonotum; coxa and femur yellow-brown, tibia and tarsus black-brown; poste ri or basitarsus armed with 6 external and 3 internal denticles; other charac ters and genitalia of the male are as for the genus. Length of body: ♂8.4?mm, ♀ 7.9?mm; width of body: ♂2.4?mm, ♀2.5?mm; length of pr onotum: ♂1.8?mm, ♀1.8?mm; length of posterior femur: ♂5.1?mm, ♂,♀5.1?mm;length of ovipositor:4. 3?mm. Holotype [QX(Y10Ca[ZK(]pillogryllus exilipalpis Xie et Liang, sp. nov.(Figs.8-10)Length of body: ♀8.2?m; width of body: ♀3.2?mm; length of pronotun: ♀2. 1?mm; length of femur: ♀5.8?mm; length of ovipositor: 5.5?mm. This new species is allied to the previous species, but differs in: 1) the apica l segment of maxillary and labial palpi are stick-shaped; 2) the third segment o f the maxillary palpus is the longest, and the fourth segment equals the fifth; 3) pronotum adorned with black-red ;4) posterior margin of ventral plate of mes o thora
