In the present paper, a new species, Pilophorus fulvicomus sp. nov., are described as new to science from China. Four species, Hallodapus indicus （Poppius）, Hallodapus kyushuensis Miyamoto, Pilophorus bakeri Schuh and Wygomiris indochinensis （Schuh）, are newly recorded from China. All type specimens are deposited in Institute of Entomology, Nankai University, Tianjin, China. Pilophorus fulvicomus sp. nov. （Figs 10-16） Body elongate, black, constricted laterally, proximal two-thirds of hemelytra covered with dense, golden, appressed setae. Clypeus invisible from dorsal view, yellow, slightly convex, apically flatted truncate. Vertex and frons covered with long, pale, slighting erect setae, carina moderately bent; mandibular plate and maxillary plate dark yellow, flat; buccula long, shining, and covered with several brown, long, erect and slighting erect setae. Labium extending to procoxa. Antenna segment Ⅰ pale yellowish-brown, darker at base; proximal two-thirds of segment Ⅱ pale yellowish-brown, apical portion deepening to black brown, slightly bent; proximal four-fifths of segment Ⅲ and proximal two-fifths of segment Ⅳ yellowish-white, apical portion black. Pronotum black, bell-shaped, slightly convex mesially, shining, with weakly wrinkle and punctures, covered with sparse, pale, slighting erect and appressed setae; posterior margin concavely sinuate. Mesoscutum exposed broad, smooth, shining. Scutellum small, flat, shining, with weakly wrinkles; basal angle with a tuft of dense, golden, spinelike setae. Proximal two-thirds of hemelytra covered with dense, golden, appressed setae, scalelike setae on hemelytra arranged into 4 distinctly patches： one is on proximal one-fifths of embolium; one is on proximal three-fifths of embolium; one is on proximal two-thirds of corium, not extend to clavus; another is in the center of clavus, close to claval commissure margin. Cuneus slender, horizontal or weakly declining, slightly shining, without scalelike setae. Membrane pale blackish brown. Mesopleuron black, smooth, shining, white scalelike setae arranged into two bands. Metapleuron without scalelike setae. Venter black, basal portion conspicuously constricted, covered with sparse, pale, short, slighting erect setae. Male genitalia. Vesica slender, C-shaped, without any projection; both hypophysis and sensory lobe of left paramere elongate, apex sharp; right paramere leaflike; phallotheca straight, beaklike apically, with a fingerlike projection. Holotype ♂, Shuiman （18°52′N, 109°40′E; alt. 600 m）, Mt. Wuzhi, Hainan Province, China, 20 May 2007, ZHANG Xu leg. Paratypes： 3♂♂, 1♀, same data as holotype; 1♀, Mt. Diaoluo （18°47′N, 109°52′E; alt. 300 m）, Hainan Province, China, 12 Aug. 2008, ZHANG Xu light trapped. Etymology. Named for corium covered with distinctly golden yellow, recumbent, sericeous setae. This new species is similar to P. decimaculatus in appearance, but differs from the basal angle of cuneus without scalelike setae, and the shaft of vesica without T-type projection. It is also similar in habitus and coloration to P. dailahn, but can be distinguished by the vesica shaft without a median barb, and phallotheca with a fingerlike projection.
