Gulamentum minutely, abundantly punctate; with yellowish-white pubescence not obscuring integument, and a few long, erect yellowish-white setae on intermaxillary process. Outer side of mandibles finely punctate, with yellowish pubescence not obscuring integument on basal half, smooth, glabrous on apical half. Distance between upper eye lobes 0.38 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.74 times distance between outer margins of eyes. Antennae 1.25 times elytral length, slightly surpassing base of posterior third of elytra. Scape finely, abundantly punctate, with yellowish-brown pubescence not obscuring integument, and short, decumbent pale yellow setae interspersed dorsally and laterally. Pedicel and antennomeres III–IV with brownish pubescence not obscuring integument, with short, decumbent pale yellow setae interspersed throughout, and long, erect dark brown setae on posterior half of inner margin. Antennomeres V–XI with yellowish-white pubescence, gradually denser toward XI; antennomeres V–VII with long brownish setae on apex of inner margin. Antennal formula based on length of antennomere III: – Scape = 0.94. – Pedicel = 0.32. – IV = 0.65. – V = 0.59. – VI = 0.53. – VII = 0.53. – VIII = 0.47. – IX = 0.47. – X = 0.47. – XI = 0.59. Thorax . – Prothorax slightly wider than long. Pronotum coarsely, abundantly punctate; with brownish pubescence not obscuring integument, except narrow, slightly distinct longitudinal yellowish-white pubescent band centrally (this pubescence more distinct close to posterior margin), and a few long, erect yellowish-white setae interspersed laterally. Sides of prothorax with sculpturing as on pronotum; with brownish pubescence not obscuring integument. Prosternum coarsely, somewhat abundantly punctate, except smooth, oblique central band laterally; with brownish pubescence not obscuring integument, more yellowish-white centrally, and a few long, erect yellowish setae interspersed. Prosternal process with somewhat abundant yellowish-white pubescence not obscuring integument, sparser on sides of posterior region, and long, erect setae of same color 6 - 8 .

C. oaxaca Martins &Galileo,2006 , paratype ♂ fromMexico ( Oaxaca ). 9 . Dorsalhabitus. 10 . Head and prothorax, lateral view. 11 . Ventralhabitus . interspersed; narrowest area 0.34 times procoxal width. Mesoventrite narrow, coarsely, sparsely punctate, except smooth sides; with sparse brownish pubescence centrally, distinctly denser laterally. Mesanepisternum and mesepimeron coarsely, somewhat abundantly punctate, punctures finer on mesepimeron; with abundant brownish pubescence not obscuring integument. Mesoventral process abruptly elevated basally, coarsely, sparsely punctate; with yellowish-white pubescence not obscuring integument; apex emarginate centrally, 0.41 times mesocoxal width. Metanepisternum and anterior half of metaventrite coarsely, sparsely punctate, punctures coarser on metaventrite; posterior half of metaventrite distinctly more elevated than anterior half, and more elevated than abdominal intercoxal process; with brownish pubescence not obscuring integument, and long, erect setae of same color interspersed on posterior region of metaventrite. Scutellum triangular-shaped; with dense pale yellow pubescence. Elytra . – Coarsely vermiculate dorsally; coarsely, somewhat abundantly punctate, punctures slightly finer toward apex; with abundant brownish pubescence not obscuring integument, and irregular yellowish-white pubescent maculae interspersed. Legs . – Femora with abundant brownish pubescence not obscuring integument, more yellowish-white on base of profemora, and a few short, bristly yellowish-white setae interspersed ventrally on meso- and metafemora. Tibiae with brownish pubescence not obscuring integument, except bristly yellowish-brown pubescence on posterior half of ventral surface of protibia, fringe of yellow setae on apex of all tibiae, dense, long, erect, abundant yellow setae on dorsal sulcus of mesotibiae, and bristly pale yellow setae on posterior quarter of ventral surface of meso- and metatibiae. Metatarsomere I shorter than II–III together. Abdomen . – Ventrite 1 coarsely, sparselypunctate laterally, punctures slightly more abundant on sides of intercoxal process, minutely, abundantly punctate on remaining surface, except smooth apex; ventrites 2–3 with a few coarse punctures laterally, more abundant on 3, minutely, abundantly punctate on remaining surface, except smooth apex; ventrite 4 minutely, abundantly punctate, except smooth apex; ventrite 5 minutely, abundantly punctate, with fine punctures interspersed. Ventrites with abundant brownish pubescence not obscuring integument, and long, erect yellowish-white setae interspersed, distinctly more abundant on 5, except glabrous apex of 1–4. Ventrite 5 twice length of 4; apex truncate. Female ( Fig. 17- 18 ). It differs from ♂ by: - Shorter antennae, as long as elytral length, reaching about middle of elytra; - Narrowest area of prosternal process wider, about 0.5 times procoxal width; - Apex of mesoventral process wider, 0.57 times mesocoxal width; - Abdominal ventrite 5 2.5 times length of 4, with apex slightly rounded. Dimensions (mm) ( holotype ♂ / paratypes ♀ ). – Total length, 5.90/5.80–7.60; – Prothoracic length, 1.65/1.30–1.85; – Anterior prothoracic width, 1.50/1.40–1.85; – Posterior prothoracic width, 1.70/1.50–2.10; – Maximum prothoracic width, 1.85/1.70–2.30; – Humeral width, 2.00/1.95–2.60; – Elytral length, 3.90/3.70–4.95. Etymology . – Greek, µικρή (mikrí), adjective meaning short (in length), allusive to the size of the metathorax.
