 Anobrium leuconotum; Morvan and Roguet 2013: 35, fig. 72.   
 Description. Holotype male. Head capsule, pronotum, sides of prothorax dark brown; antennae, femora (except reddish-brown basal area), tibiae, and tarsi orangish-brown; ventral surface of prothorax dark brown on margins, dark reddish-brown on anterior half of prosternum, mostly reddish-brown on remaining surface; ventral surface of mesothorax dark reddish-brown, except light reddish-brown base of mesoventral process; ventral surface of mesothorax dark reddish-brown, except dark brown central area of metaventrite; scutellum dark reddish-brown; elytra orangish-brown, except brownish triangular circum-scutellar region; ventrites reddish-brown, dark on ventrite 1, gradually lighter toward ventrite 5.   
 Head. Frons finely, abundantly punctate with coarse punctures interspersed; with abundant yellowishbrown pubescence on superior half not obscuring integument, pubescence distinctly sparser on inferior half, except yellowish-white pubescent band close to eyes; with long, erect yellowish-brown setae close to eyes, a few long, erect whitish setae on wide central area close to antennal tubercles, and a few moderately long, erect yellowish-white setae on remaining surface. Vertex and area behind upper eye lobes coarsely, moderately abundantly punctate; with dense yellowish-brown pubescence laterally, yellowish-white centrally (this latter pubescent area widened toward prothorax); with long, erect yellowish-white setae interspersed throughout. Area behind lower eye lobes with dense yellowish-white pubescence obscuring integument, a few long, erect yellowish-brown setae close to eye, and long, erect, sparse yellowish-white setae interspersed on remaining surface. Genae with abundant yellowish-white pubescence close to eye, glabrous on remaining surface. Gulamentum glabrous, except anterior region with a few long, erect yellowish-brown setae. Wide central area of postclypeus with abundant yellowishwhite pubescence not obscuring integument, sparser and whiter close to frons, and long, erect yellowish-brown setae interspersed; sides of postclypeus glabrous. Labrum convex, coplanar with anteclypeus on posterior quarter, gradually inclined on anterior 3/4; finely, moderately abundantly punctate; with sparse yellowish-white pubescence on posterior 3/4, and long, erect yellowish-brown setae interspersed throughout, erect setae more abundant on anterior half; anterior margin with dense fringe of golden setae. Distance between upper eye lobes 0.28 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.39 times distance between outer margins of eyes. Antennae 1.2 times elytral length, reaching posterior fifth of elytra. Scape, pedicel, and flagellomeres with abundant yellowish-brown pubescence not obscuring integument, and long, erect setae of same color interspersed, longer and more abundant ventrally, especially on antennomeres III–V.

 Etymology. Latin, “bicolor” (two-colored); allusive to the contrasting color of the pronotum and elytra.   
 Remarks. Anobrium bicolor new species is similar to A. leuconotum Galileo and Martins, 2002 (Fig. 45), and has been confused with it. However, they differ as follows: elytra slightly shorter than three times prothoracic length; pubescence on vertex and elytra distinctly denser (Fig. 40); lateral tubercles of the prothorax conical and not apically directed backward; and mesoventral process with distinct central tubercle. In A. leuconotum, the elytra are proportionally longer, slightly longer than 3.5 times prothoracic length, the pubescence on the vertex and elytra are noticeably sparser (Fig. 45), the lateral tubercles of the prothorax are spiniform and apically directed backward, and the mesoventral process has no tubercle. Anobrium bicolor is also similar to A. luridum (Breuning, 1940) (Fig. 44), but differs by the elytral pubescence distinctly denser, and the elytra proportionally shorter (about 3.5 times prothoracic length in A. luridum).
