Caraphia taiwana Chou & N. Ohbayashi, 2008 ( Figs 35, 36 , 61 , 77 , 93 , 109 , 125 , 137 ) Caraphia taiwana Chou & N. Ohbayashi, 2008 : 136 , Figs. 1–2 ( Type locality: Urai, Taipei County, Taiwan ) . Caraphia laosica (nec Gressitt & Rondon, 1978): Hua et al , 1993 : 63 , 184, pl. III, fig. 22a; Chiang & Chen, 2001 : 35 , 235; Hua, 2002 : 199 ; Chou & N. Ohbayashi, 2008 : 139 (partim); Hua et al , 2009 : 270 (note: the picture in pl. VII, fig. 83 is actually Japanopsimus Matsushita ). Diagnosis. Male: BL= 12.3–13.7 mm ; EW= 3.3–3.6 mm . Body dark reddish brown, rather stout. Antennae very long, nearly 1.7 times as long as body length and exceeding elytral apex at the middle of seventh segment; scape long and slender, 3.73 times as long as wide, relative lengths of segments from base to apex: 80: 16: 73: 80: 109: 107: 101: 104: 98: 94: 94. Pronotum longer than basal width with basal half parallel-sided, then slightly convergent apically. Elytra ca 2.4 times as long as wide, with 12 rows of foveae associated with suberect scales which are ca 1.5 times as long as the diameter of each fovea. Genitalia ( Fig. 125 ) with paramere of tegmen rather long and both sides nearly straight, 4.00 times as long as basal width, converging toward rounded apex, 0.22 times as long as the length of tegmen. Median lobe with dorsal plate slightly shorter than ventral plate; basal struts nearly 1/3 length of median lobe. Endophallus (Fig. 137) with MPH well curved dorsally, with dense hair-like spicules and a pair of sclerites near base; APH narrowed with a rod-like sclerites. Female: BL= 11.6–13.2 mm ; EW=3.0– 3.5 mm . Similar to male in body color, foveae and scales. Antennae long, 1.73 times as long as body length with apical four segments exceeding the apex of elytra; relative lengths of segments from base to apex: 76: 13: 70: 75: 112: 106: 99: 98: 101: 99: 107. Type material examined. Holotype : ♂ , Urai , Taipei County , Taiwan , 1-VI-1997 , Wei-Tsao Tsai leg. (coll. of National Taiwan University, Taipei, Taiwan ) . Paratype : 1♂ , Chien shih, Litungshan, alt. 1,500 m , Hsinchu Hsien , Taiwan , 14-VI-1994 , Liang-Chuen Lee leg. (private coll. of Chou Wen-I, Taitung , Taiwan ) . Other material examined. 1♀ , Niuxueling, Tunchang, Hainan , China , 30-V-1982 ( SYSU , En-366117); 1♀ , Nada, Danzhou, Hainan , China , 30-V-1954 , Ke-Ren Huang leg. ( IZAS , IOZ (E) 1906482). Distribution. Taiwan , China ( Hainan ). Remarks. This species has close relation with C. lepturoides , but easy to distinguish by long antennae (ca 1.7 times as long as body length instead of ca 1.4 times in C. lepturoides ). It is also resembles C. paulastoni sp. nov. but is distinguishable by the larger body size and different structure of the male genitalia. The Hainan population was misidentified as Caraphia laosica by Hua et al . (1993) , and followed by Chiang & Chen (2001) , Hua (2002) and Chou & N. Ohbayashi (2008) , but two examined specimens are identified as females of C. taiwana . 13. Caraphia paulastoni N. Ohbayashi & Lin , sp. nov. ( Figs 37, 38 ,, 62 , 78 , 94 , 110 , 126 , 138 ) Caraphia sp.: Lin & Aston, 2014 : 19 , figs. 1–6. Description. Male: BL=9.0 mm; EW= 2.5 mm . Body dark brown. Head and pronotum moderately furnished with pale yellow setaceous recumbent curved hairs; elytra provided with short scales along suture, and suberect scales which are 1.2 times as long as the diameter of each fovea along every row of foveae; scapes, legs and ventral surface furnished with short yellowish whitish hairs; scutellum and pedicel to 11th antennomeres furnished with very thin appressed pubescence. Head nearly as long as wide, widest across eyes, broader than base of prothorax, without tempora and directly narrowed to neck behind eyes; disk moderately and finely punctured; labrum very short, transverse; clypeus produced in front, trapezoidal; frons inclined anteriorly; vertex lightly depressed in U-shape; genae short; antennal insertion distinctly elevated; eyes very large, coarsely faceted, deeply emarginate near the middle of lobes around antennal insertions; interocular distance ca 0.20 times as wide as width of head. Antennae long and slender, about 1.5 times as long as body length and the middle of 8th segment exceeding the elytral apex; scape 3.7 times as long as wide, longer than 3rd and 4th, shorter than 5th which is the longest; basal 4 antennomeres cylindrical, 5th to the last ones more or less carinate, and 8th to the last ones square shaped in cross section with distinct carinae; relative lengths of segments from base to apex: 79: 14: 61: 71: 106: 100: 97: 93: 91: 89: 90. Prothorax widest near base, 1.2 times as long as wide, almost parallel-sided in basal half, then slightly convergent apically; disk lightly convex above with a transverse depression near base; apex marginate, 0.73 times as wide as basal width. Scutellum lingulate. Elytra about 2.5 times as long as basal width, widest near base, basal four-fifths nearly parallel-sided, then gently narrowed toward the truncate apices; disk provided with almost regularly arranged 11 rows of quadrate shaped deep foveae. Legs moderately long and slender; femora sub-linear; tibiae slender and slightly cambered, hind tarsi with 1 st segment shorter than 2nd and 3rd combined; 3rd tarsal segment deeply cleft. Genitalia ( Fig. 126 ) with paramere of tegmen wide and rather short, 3.13 times as long as basal width, strongly narrowed toward bluntly pointed apex, 0.18 times as long as the length of tegmen. Median lobe with dorsal plate slightly shorter than ventral plate; basal struts nearly 0.4 times as long as median lobe. Endophallus (Fig. 138) with MPH strongly turned up dorsally near basal third, with dense hair-like spicules and a pair of sclerites; APH curved oppositely with a rod-like sclerite. Female: BL=10.0 mm; EW= 2.8 mm . Similar to male, but differ from male as follows: interocular distance ca 0.26 times as wide as width of head; relative length of segments from base to apex: 80: 12: 62: 65: 103: 97: 95: 92: 89: 88: 95. Type series. Holotype : ♂ , Wang Tong, Lantau , Hong Kong , 28-V-2011 , P. Aston leg. ( IZAS , IOZ(E ) 1905360 ) . Paratype : 1♀ , same locality as for the holotype , 24-VI-2011 , Paul Aston leg. (by light trap), ( EUMJ ). Etymology. This species is named after Mr. Paul Aston, a resident coleopterist of Hong Kong who provided his material for this study. Distribution. China ( Hong Kong ). Remarks. This species belongs to the group with the elytral scales mostly associated along every row of foveae. It is very close to C. taiwana in having long antennae, but distinguishable by the smaller body, more elongate scape, and male genitalia with dorsal plate of median lobe not shorter than ventral plate.
