Description. Holotype male ( Fig. 82–88 View Figures 82–89 ). Head capsule and prothorax black (posterior area of ventral surface slightly lighter); anteclypeus and labrum mostly brownish; posterior region of ventral mouthparts brown, and anterior area yellowish-brown; scape black, slightly lighter apically; pedicel brown; basal third of antennomere III brownish and remaining surface orangish-brown; remaining antennomeres orangish-brown; ventral surface of meso- and metathorax and abdomen reddish-brown, with some irregular areas orangish-brown, and margins of thoracic sclerites darkened. Elytra orangish-brown, slightly darkened on circum-scutellar region and slightly distinct area after middle. Legs orangish-brown.

Head. Frons finely, somewhat sparsely punctate, absent on inferior sides of frontal plate; with minute, sparse white setae, slightly more abundant close to eyes. Area between antennal tubercles finely, confluently punctate, especially centrally; with minute, sparse white setae, and a few long, erect setae of same color. Area between upper eye lobes centrally carinated, rugose between eyes and carina; with a few minute white setae on rugose area. Remaining area of vertex almost smooth, except a few coarse punctures on sides of posterior area, and finely, somewhat abundant punctate area close to eyes; with minute white setae close to eyes, and a few long, erect setae of same color on same area. Area behind upper eye lobes somewhat rugose-punctate; with minute, sparse yellowish-white setae close to eye. Area behind lower eye lobes coarsely, sparsely punctate (punctures elongated), glabrous. Genae coarsely, somewhat rugose-punctate close to eye, nearly smooth apically; with minute white pubescence on rugose-punctate area. Antennal tubercles finely, sparsely punctate, except smooth apex; with minute, sparse white setae on punctate area, glabrous on smooth area. Wide central area of postclypeus finely, somewhat abundantly punctate, and sides smooth; punctures with minute white seta; with one long, erect translucent seta on each side of wide central area close to frons. Labrum with long yellowish setae laterally on posterior area coplanar with anteclypeus; anterior area with long, abundant yellowish setae directed forward centrally. Gulamentum sparsely, transversely plicate, glabrous on posterior area, coarsely, moderately abundantly punctate between eyes (general appearance somewhat rugose), punctures with short, erect whitish seta. Distance between upper eye lobes 0.06 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.37 times distance between outer margins of eyes. Antennae 1.75 times elytral length, reaching elytral apex at basal quarter of antennomere X. Scape coarsely, abundantly punctate, except smooth apical area; with whitish pubescence not obscuring integument, except glabrous smooth areas. Antennomeres III–V with whitish pubescence not obscuring integument, and remaining antennomeres with denser yellowish pubescence; antennomeres III and IV cylindrical with nodose apex; antennomeres V–X serrate; antennomere XI abruptly narrowed near apex. Antennal formula based on length of antennomere III: scape = 0.71; pedicel = 0.16; IV = 0.75; V = 0.91; VI = 0.87; VII = 0.79; VIII = 0.73; IX = 0.71; X = 0.67; XI = 0.87.

Thorax. Prothorax slightly wider than long (including lateral tubercles); lateral tubercles placed slightly after middle. Pronotum somewhat coarsely, abundantly, slightly plicate-punctate on anterior half, transversely more distinctly plicate-punctate on posterior half, except central area of posterior half only transversely plicate, and area of posterior constriction only punctate; punctures with minute whitish seta. Sides of prothorax somewhat coarsely and abundantly punctate, except for anterior area nearly smooth (this area widened toward prosternum), and posterior border and proepimeron densely microsculptured, with oblique band of shallow punctures toward procoxal cavity; punctures on wide central area with minute white seta. Prosternum coarsely, somewhat sparsely punctate on sides of posterior third, finely, densely punctate on central area of posterior quarter, coarsely, rugose-punctate on wide central region, especially on middle of this area, plicate on anterior quarter; with minute, sparse whitish setae on posterior 3/4, glabrous on anterior quarter. Prosternal process ( Fig. 87 View Figures 82–89 ) gradually inclined toward apex; narrowest area 0.15 times procoxal width. Mesoventrite coarsely, abundantly punctate, punctures with short yellowish-white seta. Mesanepisternum and mesepimeron with coarsely, somewhat abundantly punctate; punctures with short yellowish-white seta; mesoventral process without tubercle, with apical sides tab-shaped, and posterior margin strongly emarginated centrally; surface somewhat finely, densely punctate; narrowest area 0.39 times mesocoxal width. Metanepisternum and metaventrite finely, sparsely punctate; with short, sparse, decumbent whitish setae, except smooth posterior area close to metathoracic discrimen smooth and glabrous. Scutellum with minute whitish setae on sides. Elytra. Coarsely, abundantly punctate on basal half, punctures distinctly finer on posterior half; nearly all punctures with minute yellowish-white seta; apex slightly oblique, truncate. Legs. Femora coarsely, densely, shallowly punctate; with sparse white pubescence, slightly denser toward apex. Tibiae with somewhat sparse yellowish-white setae, except dense, bristly light yellowish-brown pubescence on posterior area of ventral surface. Metatarsomere I shorter than II–III together.

Abdomen. Ventrites finely, somewhat sparsely punctate; with sparse whitish pubescence, slightly denser laterally; apex of ventrite V subtruncate.

Female ( Fig. 89 View Figures 82–89 ). Very similar to male, differing especially by the antennae slightly shorter (1.6 times elytral length, reaching elytral apex at base of antennomere XI).

Variation. Posterior area of vertex and area behind upper eye lobes coarsely, transversely plicate-punctate.

Dimensions (mm) (holotype male/ paratype male/ paratype female). Total length, 8.05/8.10/9.70; prothoracic length, 1.55/1.60/1.85; anterior prothoracic width, 1.25/1.25/1.50; posterior prothoracic width, 1.35/1.40/1.65; maximum prothoracic width, 1.55/1.65/2.00; humeral width, 1.95/2.00/2.40; elytral length, 4.85/5.05/6.00.

Etymology. From the Greek “allos/αλλος”, meaning “other” or “different,” and “fasciatus ”; indicating that it is different from Hamaederus fasciatus .

Remarks. Hamaederus allofasciatus is similar to H. fasciatus ( Martins and Monné, 1975) but differs as follows: scape black, slightly lighter apically; pedicel brown; basal third of antennomere III brownish; posterior half of pronotum distinctly plicate-punctate; prosternal process gradually inclined toward apex ( Fig. 87 View Figures 82–89 ); mesoventral process ( Fig. 88 View Figures 82–89 ) distinctly narrower; elytra without transverse dark brown band. In H. fasciatus , the scape, pedicel, and antennomere III are orangish-brown, posterior half of pronotum not distinctly plicate-punctate, prosternal process abruptly inclined posteriorly ( Fig. 32 View Figures 24–33 ), sometimes somewhat tuberculate centrally near apex, mesoventral process distinctly wider ( Fig. 33 View Figures 24–33 ), and elytra with transverse dark brown band.
