Cicatrion unicolor sp. nov.

( Figs. 19–22 )

Holotype male. Integument reddish-brown, except for: head brown; scape dark- brown; mandibles blackish; antennomeres brown, gradually lighter towards distal segments; femoral club black.

Frons and frontal portion of antennal tubercles coarse, abundantly punctate; area between antennal tubercles and margin of prothorax microsculptured; vertex very fine, transversely striate; entire dorsal side with long, sparse setae. Area behind lower eye lobes moderately coarse, sparsely punctate, with long setae. Submentum laterally coarsely punctate-striate, finely striate at center; setae long, sparse. Distance between upper eye lobes equal to 0.45 times length of scape; distance between lower eye lobes, in frontal view, equal to 0.55 times length of scape. Length of antennae equal to 1.7 times elytral length; reaching elytral apex at middle of antennomere X; antennal formula based on length of antennomere III: scape = 1.31; pedicel = 0.27; IV = 0.90; V = 1.20; VI = 1.24; VII = 1.17; VIII = 1.03; IX = 0.96; X = 0.79; XI = 1.03.

Pronotum with central, longitudinal, shallow sulcus; coarse, abundantly punctate at central region, sparser and fine towards anterior and posterior margins; with long, sparse setae. Basal two-thirds of prosternum coarse, abundantly punctate; pubescence less conspicuous, interspersed with long, sparse setae; third closest to head finely striate, with long, sparse setae. Metasternum laterally abundantly punctate, gradually sparser and fine towards center; with short, decumbent, sparse setae, interspersed with long, sparse setae. Scutellum with short pubescence. Elytra coarse, abundantly punctate; with short, moderately abundant setae, interspersed with long setae. Apex of metafemora reaching distal fourth of fourth abdominal ventrite.

Legs with short setae, interspersed with distinct long setae. Urosternites coarsely punctate, interspersed with finer punctures at basal half, distinctly smoother at apical half; with short, sparse setae, interspersed with long setae.

Dimensions in mm (male). Total length, 6.2; length of prothorax at center, 1.4; anterior width of prothorax, 0.8; posterior width of prothorax, 0,8; humeral width, 1.1; elytral length, 4.0.

Type material. Holotype male, BRAZIL, Bahia: Aracatu (“Fazenda Lagoa do Tamburi”; "área de Caatinga arbórea"; 14º30.961’S / 41º27.512’W), 22.XII.2012, A. S. Ferreira & L. G. F. Sodré col. ( MZUSP).

Etymology. Latin, unicolor = with single color; relating to the elytra color.

Remarks. Cicatrion unicolor differs from C. calidum Martins & Napp, 1986 as follows: pronotum distinctly punctate; elytra without yellowish elliptical spot. In C. calidum , the pronotum is slightly punctate and the elytra have yellowish elliptical spot. It differs from C. constricticolle (Martins, 1962) by the pronotum with longitudinal, slightly distinct sulcus in males, and by the elytra without yellowish elliptical spot. In C. constricticolle , the longitudinal sulcus is well-distinct in males and the elytra have yellowish elliptical spot.

The new species can be inserted in key to species from Martins (2009) as follows:

1 Elytra without yellowish elliptical spot. Brazil (Bahia)......................................... C. unicolor sp. nov.

- Elytra with yellowish elliptical spot....................................................................... 2

2(1) Pronotum (♀) microsculptured; pronotum (♂) with shallow, center longitudinal sulcus; elytra with dorsal, small yellowish spot; femora reddish. Brazil (Bahia, São Paulo)................................... C. constricticolle (Martins, 1962)

- Pronotum (♀) without microsculpture; pronotum (♂) uniformly convex; elytra with more developed yellowish spot, almost touching the margins; femora darkened at apical half. Brazil (Bahia, Minas Gerais)...... C. calidum Martins & Napp, 1986
