Treatment

Neocerambyx guangxiensis sp. nov. ( Figs. 1–2 View FIGURE 1 View FIGURE 2 )

Type materia l. Holotype, ♂, China, Guangxi, Mt. Damingshan , VI .2014, local collector ( SWU); Paratypes, 1♂, Guangxi, Nanling Reserve , 1–20. VI .2012, H. X. Shun leg. ( CFV); 1♀, ditto, but 1–15. VI .2011 ( CFV) .

Description ( Fig. 1 View FIGURE 1 ). Body length: 53.8–72.0 mm, humeral width 14.0–18.0 mm. Body large, head and pronotum dark brown; antennae and elytra reddish brown; legs dark reddish brown. Pronotum with erected yellowish pubescence; head, antennae, scutellum, elytra, legs, and abdomen with recumbent yellowish pubescence.

Head with deep median groove between eyes and partly on vertex; antennal tubercles moderately developed. Antennae of male longer than body, exceeding elytral apex by one to two segments; scape strongly widened apically with a strong and sharp apical spine; antennomeres III–V swollen; antennomere III slightly longer than scape, IV and V; antennomere VI twice as long as V and shorter than VII; last antennomere longest. Antennae, in females, reaching apical seventh of elytra, antennomeres III–V not swollen, antennomere III longer than IV and scape. Pronotum wider than long; disc with irregular transverse ridges. Scutellum subtriangular. Elytra 2.8 times as long as basal width, parallel-sided and slightly narrowed at apex; elytral apices transversely truncated with a small tooth at the sutural angle. Legs moderately long; metatarsomere I about as long as the following two tarsomeres combined.

Male terminalia. Tergite VIII ( Fig. 2a View FIGURE 2 ) broader than long, apex emarginated, densely clothed with short setae; tegmen curved in profile ( Fig. 2b View FIGURE 2 ); parameres elongate, with long setae; median lobe slightly ( Fig. 2c View FIGURE 2 ) curved in profile; median struts about one-half as long as the whole median lobe in length; ventral plate slightly longer than dorsal plate; apex of ventral plate sharpened; median foramen rounded.

Etymology. The name refers to the type locality, Guangxi Province, China.

Diagnosis. The new species is similar to N. katarinae Holzschuh, 2009 ( Fig. 3 View FIGURE 3 ) but differs in the shorter and more inflated third antennomere in male, as in Figs. 1a, d View FIGURE 1 (in N. katarinae as in Figs. 3 View FIGURE 3 a–b); the more transverse wrinkles of the pronotum, as in Fig. 1b View FIGURE 1 (in N. katarinae as in Fig. 3c View FIGURE 3 ); and the different shape of tergite VIII, as in Fig. 2a View FIGURE 2 (in N. katarinae as in Fig. 3d View FIGURE 3 ). Also, the antennae, in females of the new species, are longer than in females of N. katarinae .
