Abstract: The present paper deals with six species of Chinese Nabidae, among them threespecies are recorded for the first time from this country, and two species and one subspe-cies are described as new to scienee. The new taxa are diagnosed as follows. All themeasurements are in millimeters.. Stenonabis hainana, sp. nov. (figs. 1-2) Fulvous, clothed with pale short hairs and sparse long hairs. Annuli of antennae,central longitudinal stripe of pronotum, scutellum (except lateral areas yellow), veinsof membrane, and longitudinal median stripe of genital segment fuscous. total length 7.9. Head length 1.2, width 0.85, vertex width 0.35. Length of anten-nal segments Ⅰ:Ⅱ:Ⅲ:Ⅳ=1.2:1.6:2.0:1.8. Length of rostral segments Ⅱ:Ⅲ:Ⅳ=1.1:0.96:0.5. Pronotum length 1.6, width of apex 0.71, width of posterior margin 1.8. Heme-lytra length 5.8, passing apex of abdomen, width of abdomen 1.85. Pronotum slightlyconvex on anterior lobe, posterior lobe densely punctate. Male claspers very large, con-structed as in fig.2. Holotype: Hainan Island (Beijing Natural History Museum). Allied to Stenonabis javanus (Poppius), but larger, hemelytra long, and malegenital claspers differently constructed. Aptus pulchellus, sp. nov. (figs. 3-4) Body fuscous, clothed with yellow short dense hairs intermixed with long sparse darkhairs. Eyes, antennae, rostrum (except pale rings), dorsum and sides of head (except alongitudinal black stripe on vertex), lateral area of pronotum, and longitudinal line onanterior lobe, scutellum, a spot near central area of corium and membrane (except ex-terior margin pale) all blackish-fuscous; vertex (except middle black), rings of rostrumand marks on legs flavotestaceous. total length 9.2, width of abdomen 2.7. Head length 1.2, width 1.05, width ofvertex 0.45. Length of rostral segments Ⅱ:Ⅲ:Ⅳ=1.2:1.1:0.5. Length of antennalsegments Ⅰ:Ⅱ:Ⅲ:Ⅳ=1.1: 1.87:1.4:1.0. Length of pronotum 1.85, width at apex 0.75,width of base 2.5. Length of scutellum 1.1, width of base 1.2. Hemelytra length 6.5,passing apex of abdomen. Pronotum shorter than width at base, collar distinct, middlearea of anterior lobe slightly convex. Male genital claspers constructed as in fig. 3. Holotype: Yunnan (Tianjin Natural History Museum). Allied to Aptus myrmecoides Costa, but body larger, pronotal lateral angles expand-ed, coloration brighter, and male claspers different in form. Nabis pseudoferus chinensis, subsp. nov. (figs. 5-7) Vertex and lateral of head, central longitudinal stripe of pronotum (sides of prono-tum on anterior lobe dark), longitudinal marking of scutellum, mesosternum and metas-terum, central longitudinal fascia on dorsum of abdomen, and median longitudinal stripeof sternum all blackish-fuscous; membrane of hemelytra with two pale-fuscous spots. total length 6.3. Head length 1.1, with 0.95, vertex width 0.4. 1st antennal segmentshorter than head; length of segments I:Ⅱ:Ⅲ:Ⅳ=0.95:1.46:1.1:0.9. Length of rostralsegments Ⅱ:Ⅲ:Ⅳ=0.85:0.85:0.5. Pronotum length 1.33, width of apex 0.75, width ofposterior margin 1.4. Hemelytra length 2.5, nearly reaching posterior margin of 6thabdominal tergite, width of abdomen 2.12. Male parameres constructed as in fig. 7. total length 7.8, width of,abdomen 2,7. Hemelytra length 3.0, reaching anteriormargin of 6th tergum of abdomen, color paler than male. Holotype and allotype, Hubei; paratypes 2, 3: Hubei,S chuan, Yunnan.(Biology Department of Nankai University). Body color darker than Nabis pseudoferus pseudoferus Remane. Clasper with apicalthird of inner margin thickened, somewhat protruding out and dark in color.
