description: 8. Caraphia borneana Vives, 2005
(Figs 23, 24, 47, 57, 73, 89, 105, 120)
Caraphia borneana Vives, 2005: 305, fig. 3 (Type locality: Mt. Trus Madi, Borneo); Chou & N. Ohbayashi, 2008: 142, fig. 5.
Diagnosis. Male: BL=10.0 mm; EW= 2.5 mm. Body yellowish brown. Antennae with apical three segments exceeding elytral apex; scape 3.7 times as long as wide; relative lengths of segments from base to apex: 85: 16: 52: 66: 106: 95: 89: 81: 82: 81: 90. Pronotum as long as basal width, nearly straightly convergent from base to apex; sub-recumbent scales becoming denser laterally.
Elytra densely and rather regularly foveate in rows; scales pale yellow, suberect and barely curved, nearly as long as the diameter of each fovea, alternating on rows of foveae.
Genitalia (Fig. 120) with paramere of tegmen very short and wide, 1.49 times as long as basal width, slightly narrowed toward rounded apices, 0.15 times as long as tegmen. Median lobe with dorsal plate slightly shorter than ventral plate. Endophallus was failed to observe.
Female: BL=8.5–10.0 mm; EW= 20–25 mm. Very similar in general features with male, relative lengths of segments from base to apex: 82: 15: 53: 66: 105: 94: 89: 81: 84: 77: 89.
Material examined. 1♂, 4♀♀, 16 miles point of Keningau, alt. 1,400 m, Sabah, Borneo, 17–21-V-1983, 22- IV–6-V-1984, S. Nagai leg. (EUMJ); 1♀, S. Bingkor, Keningau, Sabah, Malaysia, 31-III–5-IV, 1981, A. Kurachi and T. Hirowatari leg. (EUMJ); 1♀, Kimanis Road, Nr. Keningau, Sabah, Borneo, 26–30-III-1992, N. Kanie leg. (EUMJ).
Distribution. Malaysia (Sabah).
Remarks. This is a small species of less than 10 mm long. Other than the small size, it is characterized by the short elytral scales and very short and wide parameres of tegmen. It seems to be endemic to Borneo Island.
9. Caraphia huai N. Ohbayashi & Lin, sp. nov.
(Figs 25, 26, 27, 58, 74, 90, 106, 121, 134)
Description. Male: BL= 8.4 mm; EW= 2.2 mm. Body dark brown; elytra, antennae except dark scapes and legs reddish to yellowish brown. Head moderately, and pronotum sparsely furnished with pale yellow recumbent setaceous scales. Elytra provided with short scales along suture, and suberect scales on 6 alternating rows of foveae; scutellum, scapes and legs furnished with short whitish hairs, and ventral surface moderately with recumbent rather long whitish hairs.
Head nearly as long as wide, widest across eyes, wider 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 flattened; genae short; antennal insertion distinctly elevated; eyes very large, coarsely faceted, deeply emarginate near the middle of lobes around antennal insertions; interocular distance ca 0.2 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 3.5 times as long as wide, longer than 3rd and 4th, shorter than 5th which is the longest; basal 4 segments cylindrical, 5th to 7th 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: 77: 15: 62: 70: 103: 98: 93:90: 92: 92: 100.
Prothorax widest near base, 1.10 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 narrowly marginate, 0.78 times as wide as basal width. Scutellum lingulate.
Elytra about.2.55 times as long as basal width, widest near base, basal four-fifths nearly parallel-sided, then gently narrowed toward truncate apices; disk lightly swollen on both sides behind scutellum, provided with almost regularly arranged 11 rows of quadrate shaped deep foveae; scales 1.5 times as long as the diameter of each fovea.
Legs moderately long and slender; femora sub-linear; tibiae slender and slightly cambered, hind tarsi with first segment shorter than second and third combined; 3rd tarsal segment deeply cleft.
Genitalia (Fig. 121) with paramere of tegmen 4.35 times as long as basal width, slightly emarginate on basal third of outside, then gently attenuate apically, 0.23 times as long as the length of tegmen. Median lobe with dorsal plate slightly shorter than ventral plate; basal struts nearly one-third of the length of median lobe. Endophallus (Fig. 134) with MPH slightly curved dorsally, with dense hair-like fine spicules and a pair of sclerites near base; APH narrowed, with a rod-like sclerite.
Female: BL= 9.2–9.3 mm; EW= 4.7–4.8 mm. Very similar in general features with male; relative lengths of segments from base to apex: 69: 14: 59: 63: 106: 95: 91: 89: 88: 86: 91.
Type series. Holotype: ♂, Mohaocun, Fangtianlu, 19.01021°N, 109.36910°E, alt. 300 m, Baisha County, Yinggeling, Hainan, 16-IV-2010, Mei-Ying Lin leg. (IZAS, IOZ (E) 1905200). Paratypes: 1♀, Heishiding, Fengkai, Guangdong, 7-V-2010, Hai-Dong Chen, Hong-Sheng Wu, Yong-Jun Li and Hong Pang leg. (SYSU, En- 382340); 1♀, Danxiashan, Shaoguan, Guangdong, 30-V–8-VI-2008, Yun Wang leg. (SYSU, En-319744).
Etymology. The species name is dedicated to Professor of Sun Yatsen University, Guangzhou, Hua Li-Zhong who is one of the great pioneers on the taxonomy of Chinese Cerambycidae.
Distribution. China (Hainan, Guangdong).
Remarks. This new species is very close to C. thailandica, but can be distinguished by short elytra (EL/ EW=2.55–2.62 instead of 2.68–2.75), and short parameres of tegmen.
