Diagnosis

Head, pronotum, and elytral base slightly darker than remaining surface of body. Surface of pronotum with sparse, fine punctation centrally; tubercles black, and slightly elevated; black spots around tubercles extending toward posterior margin of prothorax. Each elytron with two anterior eburneous callosities of different size; elytral apex with two spines, a long external one, and a small sutural one; femoral spines slightly darker than legs. Male with sexual punctation on sides of pronotum and prosternum.

Description. Male ( Figs 1–4 View FIGURES 1–8 , 9–10 View FIGURES 9–12 )

Integument brownish orange. Pronotal tubercles black, surrounded by black area extended backward, almost reaching posterior margin of prothorax. Area close to posterior region of anterior eburneous elytral callosities, close to anterior and posterior regions of posterior eburneous elytral callosities, and close to inner margin of innermost posterior callosity black. Ventrites with small darker region laterally.

Head. Vertex with sparse white pubescence. Upper eye lobes well separated, distance between them about three times width of one upper lobe. Antennae reaching elytral apex at antennomere VIII. Antennal formula (ratio) based on length of antennomere III: scape = 0.7; pedicel = 0.13; IV = 0.91; V = 0.88; VI = 0.82; VII = 0.79; VIII = 0.76; IX = 0.68; X = 0.62; XI = 0.75.

Thorax. Prothorax (including lateral tubercles) wider than long. Sides of prothorax with distinct tubercles, acute on apex. Pronotum with coarse sexual punctation laterally, central area with sparse, fine punctation; with dense whitish pubescence, interspersed with a few long setae arising from sexual punctuation; with two anterior tubercles slightly elevated, smaller than pedicel, rounded apically. Anterior fifth of prosternum smooth, remaining surface with sexual punctation except on prosternal process; with sparse white pubescence not obscuring integument ( Fig. 9 View FIGURES 9–12 ). Prosternal process expanded apically, width in narrowest area one-third of width of procoxal cavity. Prosternal process, meso- and metaventrite with dense white pubescence, denser laterally. Elytra about three times longer than prothorax; punctation slightly denser and coarser on anterior half, sparser and shallower toward apex; entirely with long, erect setae; Each elytron with two elytral costae slightly elevated; with four narrow and elongate eburneous callosities: two anteriorly, outermost shorter than innermost, slightly curved; two posteriorly, contiguous, starting at same level, innermost slightly shorter than outermost; elytral apex truncate, with two spines: external one long and sutural one small. Legs with dense long, erect yellowish setae.

Abdomen. Ventrites with sparse, uniform, fine punctation; with dense whitish pubescence, slightly sparser toward center. Apex of ventrite 5 curved.

Female ( Figs 5–8 View FIGURES 1–8 )

Integument yellowish orange. Prothorax cylindrical, with lateral tubercles well developed; with dense whitish pubescence. Black area surrounding pronotal tubercles larger than in males, almost reaching anterior margin and lateral tubercles. Antennae shorter than in males, exceeding elytral apex at base of antennomere XI. Antennal formula (ratio) based on length of antennomere III: scape = 0.69; pedicel, = 0.13; IV = 0.81; V = 0.78; VI = 0.78; VII = 0.78; VIII = 0.74; IX = 0.65; X = 0.56; XI = 0.70. Anterior eburneous elytral callosities with same length. Elytral apex with external spine shorter. Prosternal process with wrinkles on anterior region. Ventrites without lateral dark region.

Antennal formula (ratio) based on length of antennomere III: scape = 0.69; pedicel, = 0.13; IV = 0.81; V = 0.78; VI = 0.78; VII = 0.78; VIII = 0.74; IX = 0.65; X = 0.56; XI = 0.70.

Measurements

Holotype male/ paratype female: total length, 13.9/12.4; prothorax length, 3.0/2.5; prothorax width at its widest point (including lateral tubercles), 3.3/2.9; elytral length, 9.8/8.5; humeral width, 1.5/1.4.

Etymology

The species’ epithet refers to the locality where the paratype was collected, the Santuario de Flora y Fauna los Colorados (SFFC).
