(Figures 1–3)
Description. Female. Integument dark-brown; pubescence and setae straw-colored, except for yellow pubescence on anterior and posterior margins of prothorax and scutellum.
Head. Frons centrally tumid, coarsely, confluently punctate; pubescence centrally sparse, laterally denser. Clypeus laterally notably tumid; coarsely, moderately abundantly and shallowly punctate; pubescence centrally sparse, laterally denser, interspersed with long and very long, sparse setae. Antennal tubercles remarkably raised, forming as flap-like upon part of lower eye lobes; centrally deeply emarginated; area in front emargination with moderately large, deep depression; with a wide, well-marked longitudinal sulcus from near depression towards posterior side; surface coarsely, confluently punctate, coarse punctate-rugose on some areas; pubescence sparse, interspersed with long, sparse setae. Area between antennal tubercles and upper eye lobes with raised longitudinal carina, narrowed, more elevated between upper eye lobes. Vertex punctate-rugose; pubescence sparse, interspersed with long, sparse setae. Area behind upper eye lobes coarsely, moderately sparsely punctate; pubescence sparse, interspersed with long, sparse setae. Area behind lower eye lobes tumid and coarse punctate-rugose close to eye, finer, sparser punctate towards anterior margin of prothorax; pubescence on tumid region moderately sparse, interspersed with abundant long setae; pubescence sparser on remaining surface, mainly towards anterior margin of prothorax. Genal apex projected forward; coarse sparse punctate on basal half, distinctly sparser, finer on distal half; pubescence sparse on basal half, almost glabrous on distal half. Gula finely, sparsely punctate; transversely, moderately deeply sulcate; almost glabrous. Submentum coarsely, sparsely punctate; with wide, very deep, transverse sulcus near middle; with sparse, short setae, interspersed with long, sparse setae. Mandibles laterally coarsely, confluently punctate; with short, moderately sparse, short setae, interspersed with long setae. Distance between upper eye lobes equal to 0.6 times length of scape; distance between lower eye lobes, in frontal view, about equal to length of scape. Antennae as long as 1.2 times elytral length; reaching elytral distal quarter; scape, pedicel and antennomeres with short, sparse pubescence (denser throughout on inner half), interspersed with moderately abundant long setae, mainly on inner half (longer, present throughout on antennomere III); antennal formula based on antennomere III: scape = 0.78; pedicel = 0.19; IV = 0.45; V = 0.59; VI = 0.59; VII = 0.57; VIII = 0.53; IX = 0.51; X = 0.45; XI = 0.55.
Thorax. Prothorax slightly wider than long. Lateral sides of prothorax with central, blunt tubercle; pubescence and sculpture similar to that of lateral of pronotum.
Anterior lateral sides of pronotum distinctly downgraded; raised area with smooth, glabrous central callosity, laterally with distinct, confluent gibbosities; anterior region of raised area finely, abundantly punctate; remaining surface of raised area coarsely punctate-rugose, interspersed with fine, sparse punctures; remaining surface of pronotum coarse, vermiculate-punctate, mainly laterally; pubescence centrally sparse, mainly on distal two-thirds, laterally denser, interspersed with long, sparse setae. Prosternum with two wide, deep, transverse sulcus; basal half coarse, confluent punctate, pubescence denser inside transverse sulcus, interspersed with long, sparse setae; anterior half with oblique, moderately fine vermiculation, with sparse short setae, interspersed with long, sparse setae. Prosternal process with short, moderately abundant setae on basal half, interspersed with long, sparse setae; posterior half laterally with short pubescence, centrally almost glabrous; vertically sloped after procoxae. Metathorax laterally with fine, sparse punctures, gradually sparser towards middle; with short, moderately abundant setae, interspersed with long, sparse setae. Scutellum laterally abundantly pubescent, centrally almost glabrous on basal and distal third. Elytra. Finely, moderately abundantly punctate; with short, sparse setae throughout, interspersed with long, sparse setae; apex rounded, with short spine at sutural angle.
Abdomen. Urosternites finely, sparsely punctate, mainly centrally on urosternite I; covered with short, moderately abundant setae, interspersed with long, sparse. Legs. Inner apex of mesofemora, and inner and outer apex of metafemora with short spiniform projection; metatarsomere I about as long as 0.8 times length of II-III together.
Male. Antennae as long as 1.6 times elytral length; reaching elytral apex at basal third of antennomere XI; antennomere XI almost divided in two segments after middle; antennal formula based on antennomere III: scape = 0.56; pedicel = 0.16; IV = 0.45; V = 0.60; VI = 0.56; VII = 0.56; VIII = 0.54; IX = 0.54; X = 0.56; XI = 0.80.
Variability in females. Outer elytral apex slightly projected; elytral sutural angle with very distinct spine.
Type material. Holotype female from BOLIVIA, Santa Cruz: 20 km N Camiri (Road to Eity; 1250 m; 6–8 km E highway 9; 19º52’S / 63º29’W), 5–10.XII.2012, Wappes, Bonaso and Skillman col. (MNKM). Paratypes: same data as holotype, 1 male, 2 females (ACMT); 1 female (MZSP).
Dimensions in mm (male/ holotype female/ female). Total length, 34.7/36.0/35.2–41.0; length of prothorax at center, 6.2/6.4/6.1–7.1; largest width of prothorax, 7.4/7.3/7.5–8.1; anterior width of prothorax, 6.2/5.7/6.5–7.7; posterior width of prothorax, 5.9/6.1/6.0–6.6; humeral width, 7.3/8.3/8.4–9.5; elytral length, 21.6/23.2/22.2–26.0.
Etymology. Latin, spinosum = spiny; allusive to the apex of metafemora.
Remarks. Criodion spinosum sp. nov. differs from C. subpubescens Martins & Monné, 2005 (female) as follow: antennal tubercles coarsely rugose; carina in the area between antennal tubercles and eyes narrower and raised; scape rugose; pronotal pubescence distinctly sparse; anterior third of pronotum without a distinct tubercle at center; central callosity of pronotum narrower; elytral pubescence slightly long and sparse; apex of metafemora with short spine at inner and outer angles. In C. subpubescens the antennal tubercles are slightly rugose (almost just punctate), the carina in the area between antennal tubercles and eyes is wider and moderately low, only the scape is punctate, the pronotal pubescence is denser, the anterior third of pronotum has a central tubercle, the central callosity of pronotum is wider, the elytral pubescence is slightly shorter and denser, the apex of metafemora has rounded lobes.
Criodion spinosum can be included in the alternative of couplet “1”, from Martins & Monné (2005) (translated; modified):
1. Elytra with sparse pubescence, not obliterating integument.................................................... 1’ - Elytra with pubescence distinctly dense throughout.......................................................... 2 1(1’). Antennal tubercles slightly rugose (almost just punctate); pronotal pubescence dense; apex of metafemora with rounded lobes.
Brazil (Amazonas)......................................................................... C. subpubescens - Antennal tubercles coarsely rugose; pronotal pubescence sparse, mainly centrally; apex of metafemora with short spine at
outer and inner sides. Bolivia ............................................................ C. spinosum sp. nov.
