(Figs 6–7, 16–18)
Female. Length: 30 mm; humeral width: 8.5 mm. Body and antennae violet­blue with metallic luster. Elytra black, crossed by a broad pale­yellow band from about the basal one­fifth to the apical two­fifths. Anterior margins of clypeus and pronotum fringed with long hairs, posterior margin of pronotum with shorter hairs, and the lower margins of third to sixth antennal segments fringed with sparse hairs. Antennae bearing short black pubescence which become denser toward apex. Pronotum with a circular black maculation of dense short pubescence at each side of the median portion of the disc, and a semicircular patch of same pubescence on the elevated anterior portion (Figs 6–7). Legs subglabrous. Elytra clothed with pubescence corresponding to ground colour. Ventral surface of thorax and abdomen with dense silvery­yellow pubescence.
Body moderately large. Mandibles stout, finely and sparsely punctate, with apex strongly curved to the central line of the head, nearly rectangular (Figs 16–17), and lateral surface deeply depressed (Fig. 18) and coarsely rugulose at the base. Frons coarsely rugulose and sparsely punctate, with a longitudinal sulcus broadening toward apex and terminating at the posterior margin of the eyes, a distinct depression before the eyes and behind clypeus, two prominent calli between eyes just behind the depression. Antennal tubercules prominently protruding, vertex broadly concave in frontal view. Occiput coarsely punctate­rugulose. Antennae barely longer than body, scape coarsely punctate, with sharper ectoapical angle than other congeners; the remaining segments densely punctate, with a seta projecting from each puncture. Pronotum broader than long, coarsely reticulate­rugulose, with anterior and posterior transverse constrictions; disc with a glabrous longitudinal sulcus broadening distinctly anterior to the pubescent maculations. Scutellum triangular, shining, with a few punctures. Elytra long, with subparallel sides and rounded apical margin. Legs sparsely punctate, hind femora not reaching the apex of elytra, hind tibiae and first metatarsal segment compressed laterally, the latter longer than the following segments together. Posterior margin of apical abdominal ventrite nearly straight.
Male. Unknown.
Type material. Holotype, female, CHINA: Maoershan Nature Reserve, Xing’an County, Guangxi Province, 25° 55' N, 110° 33' E, 400 m, 30 June 1990, Wenfei Deng.
Type depository. The holotype is deposited in insect collection of College of Life Sciences, Guangxi Normal University, Guilin, P. R. China.
Etymology. The new species is named from Latin words “pubes” and “maculatus” referring to its circular maculation of dense short pubescence on the disc.
Diagnosis. The new species very closely resembles E. unifasciata (Ritsema), but can be distinguished from that species by its violet­blue antennae, circular maculations of dense short pubescence on the disc, mandibles with deep depressions on the lateral sides and strongly curved apex.
