摘　　要：鞭蝽科(Dipsocoridae)为小型的捕食性昆虫,体长约1—3,色泽一般为黄褐、褐色,光亮;体长形。头似三角状,前端向前突,不强烈向下倾斜;复眼小,具单眼;触角细长,第1、2两节短,第2节显著长于第1节,第3、4两节长,纤细,具稀疏长毛。喙一般细长,达到或略超过后足基节。翅的长短常有变异,具翅室;前翅前缘近中部有楔片缝(楔片缝长者,可达革片的中部)。跗节2节或3节。雄虫生殖节构造复杂;雌虫生殖节一般有产卵瓣。The present paper deals with three species of two genera (Ceratocombus,Cryptostemma) of Chinese Dipsocoridae,including two new species and one new record (Cryptostemma japoni-cum Miyamoto).The type specimens are deposited in the Department of Biolosry,Naakai,University.All measurements in the description are in millimeters.Dipsocorid bugs are for the first time recorded from this country.The new species are diagnosed as follows.Ceratocombus alticallus Ren et Yang,sp.nov.(figs.1-4)Body pale yellow-fulvous,a little shining,with iridescence;eyes and ocelli red;hemely-tra darker than pronnrum in color rostrum,antennae and legs rather yellowish Total length 1.67,width of abdomen 0.63 Length of antennal segments Ⅰ:Ⅱ:Ⅲ:Ⅳ=0.1:0.21:0.57:0.53.Pronorum convex,lateral margins of pronotum straight and reflected,posterior margin insinuated.Female with ovipositor,second valvula as shown in fig.3,the sper-matheca reniform (fig.4).Holotype Hebei Province,rotten wood,1973.Ⅶ.27,Yang Chi-kun leg.The new species allied to Ceratocombus coleoptratus Zett.in colour and appearance,but body small,relative lengths of antennal segments and vena of hemclytra are different;lateral margins of pronotum straight and reflected.Ceratocombus sinicus Ren et Yang,sp.nov.(figs.5-7)Yellowish-flulvous,eye darked red,ocelli red.Body length 1.4,width of abdomen 0.6,length of antennal segments Ⅰ:Ⅱ:Ⅲ:Ⅳ=0.07:0.35:0.36.Rostrum long (0.75),reaching apex of anterior coxae,length of segments Ⅰ:Ⅱ:Ⅲ=0.13:0.25:0.27.Base of abdomen retracted,its apex with ovipostor.Hemelytra considerably exceeding the apex of abdomen.Holotype Beijing 1955.IX.25,Yang Chi-kun leg.The species is closely related to Ceratocombus (X.) japonicus Poppius,but body small in size;posterior margin of pronotum longer than anterior margin,pronotal lateral margins straight;costal margin wider,strongly sclerotized than the rest of corium.
