Description
Size. Overall length (sbl) 21.3-21.8mm, greatest width over elytra 8.3-9.0mm. Color. Dorsal and ventral surfaces black, legs, mouthparts, and antennomeres black to piceous. Luster. Dorsal surface dull, head and lateral edges of elytra contrastingly smoother and shinier, ventral surfaces moderately shiny. Iridescence. No spectral iridescence dorsally. Ventral surface of body with slight spectral iridescence laterally on abdomen and on prothorax. Head. Dorsal microsculpture with microlines hardly visible at 50x magnification, sculpticells small, forming isodiametric or slightly irregular mesh, clypeal-ocular sulci not impressed, represented as broad shallow depressions, ocular ratio 1.3, eyes small, rounded, not prominent, post-ocular small. Labrum anterior margin straight. Antennae: Overall length very long, antennomeres 8-11 reaching beyond base of pronotum, antennomeres very elongate. Thorax. Pronotum trapezoidal, base notably wider than apex, sides shallowly rounded to base, marginal bead continuous from apex to near base, base without marginal bead, hind angle right angled, anterior margin emarginate, anterior angles produced, inner basal impressions broad, shallow, not well impressed or defined, convergent, outer impression lacking, seta at hind angle in basal marginal bead, about one pore width from lateral margin. Dorsal surface dull, microsculpture visible at 50x magnification as irregular mesh. Macrosculpture densely pappilous laterally, irregularly rugose on disc. Elytral striae complete, very shallowly impressed, smooth. Parascutellar stria present, angular base of stria 1 absent. Elytra dull except for contrastingly shiny intervals 8-9, microsculpture visible at 50x as irregular mesh. Macrosculpture densely pappilous. Metacoxal sulcus straight and ended at lateral end of coxa. Abdomen. Last abdominal ventrite with narrow apical bead. Female unknown, male aedeagus (20A) narrow, with tip narrow and slightly expanded and rounded.
Etymology. The specific epithet, curtus is Latin for short, in recognition of the relatively short and broad form of these beetles is treated as an adjective.
