Megasybacodes brevitarsis Kakizoe, Maruyama & Masumoto , new species

( Figs. 1–5 )

Type material. Holotype, female, deposited in the Kyushu University Museum, Fukuoka, Japan : MALAYSIA, Borneo , Sabah, Near Keningau , IV 2003, local collector leg.

Description of holotype female. Head ( Figs. 1–3 ) narrower than pronotum with a ratio of pronotal width to head width ca. 1.06; clypeus densely punctate-microsetose. Pronotum ( Figs. 1, 3 ) distinctly shorter than elytra with a ratio of elytral length to pronotal length ca. 1.98, with surface strongly wrinkled except carinae. Elytra ( Figs. 1, 3 ) with a ratio of length to width ca. 1.39; strongly wrinkled and almost glabrous except for microsetae at top of carinae. Protibiae ( Fig. 1 ) densely setiferous near apex. Mesotibiae ( Fig. 1 ) densely setiferous on anterior and lateral margins. Metatibiae ( Fig. 1 ) with setae of similar densities to mesotibiae.

Male. Unknown.

Measurements. Body length 8.91 mm; maximum width of head 2.51 mm; median dorsal length of pronotum 2.66 mm, maximum width 3.71 mm; sutural length of elytra 5.27 mm, maximum width 3.79 mm; maximum width of epipharynx 0.52 mm.

Diagnosis. This species is similar to the members of the genus Sybacodes in general appearance but is easily distinguished by the generic diagnostic features described above.

Etymology. A combination of the Latin word brevis meaning “short” and tarsi, in reference to the short tarsi.
