Colombicallia setosa Santos-Silva, Bezark and Galileo , sp. nov.

( Figs. 5–8 )

Male. Integument orangish-brown; head mostly brown dorsally; sides of pronotum reddish-brown; center-basal area of pronotum reddish-brown; sides of prothorax, sides of ventral surface of meso- and metathorax brown; mandibles black; scape mostly reddish-brown dorsally, more brownish ventrally; pedicel brown; antennomere III reddish-brown, slightly darker on apex; antennomere IV orangish-brown on basal 2/3, brown on distal third; antennomeres V–XI orangish-brown on basal third, brown on distal 2/3; punctures on pronotum and basal half of elytra dark brown; tarsi mostly brownish.

Head. Frons rectangular, coarsely, abundantly punctate (punctures partially obscured by pubescence); pubescence yellowish, moderately dense, less so along longitudinal sulcus, interspersed with long, erect and suberect, thick, dark setae, mainly laterally. Area between antennal tubercles and upper eye lobes coarsely, sparsely punctate; pubescence moderately dense, not obscuring punctures, interspersed with long, erect, yellowish setae. Area between upper eye lobes and prothoracic margin pubescent, impunctate. Area behind eyes densely pubescent (less so toward ventral side of lower eye lobes), interspersed with some long, erect, yellowish setae behind lower eye lobes. Submentum with pubescence not dense, interspersed with long, erect, yellowish setae. Genae glabrous close to eyes (glabrous area wider toward ventral side), with moderately sparse pubescence near apex. Distance between upper eye lobes 0.45 times length of scape; distance between lower eye lobes in frontal view 0.85 times length of scape. Antennae 1.75 times elytral length, reaching elytral apex at middle of antennomere VIII; scape coarsely, sparsely punctate, with decumbent, moderately sparse setae, interspersed with long, erect setae; ventral side of antennomeres with long, erect setae (darker toward distal antennomeres); light region of antennomeres ringed with yellowish-white pubescence; antennal formula (ratio) based on antennomere III: scape = 0.62; pedicel = 0.14; IV = 0.78; V = 0.47; VI = 0.44; VII = 0.41; VIII = 0.37; IX = 0.36; X = 0.29; XI = 0.31.

Thorax. Prothorax subcylindrical, with pronotum moderately flat centrally, wider than long (1.35 times wider than long, including lateral tubercles); sides with acute tubercle just before middle. Pronotum coarsely, abundantly punctate (punctures distinctly denser laterally); pubescence yellowish, not notably dense, not obscuring punctures, interspersed with long, suberect, yellowish setae throughout, and thick, dark setae on anterior third. Sides of prothorax coarsely, densely punctate, with pubescence not obscuring punctures. Prosternum pubescent laterally, gradually with decumbent, sparse setae toward middle, where there are long, abundant, erect, yellowish-white setae; moderately finely, sparsely punctate laterally, slightly denser toward middle. Prosternal process with long, erect, abundant, yellowish-white setae. Mesosternum finely, sparsely punctate centrally, impunctate laterally; pubescence denser laterally, distinctly sparser toward middle. Mesepisterna coarsely, abundantly punctate; pubescence yellowish-white, not obscuring integument. Mesepimera impunctate, with yellowish-white pubescence. Mesosternal process with long, erect, yellowish-white setae. Metepisterna with yellowish-white pubescence. Metasternum coarsely, abundantly punctate laterally, distinctly sparser toward middle; central area close to mesocoxal cavities slightly transversely striate; with yellowish-white pubescence, denser laterally, not obscuring integument, interspersed with long, abundant setae on central area close to mesocoxal cavities. Scutellum with dense, yellowish-white pubescence, contrasting with that on elytra.

Elytra. Coarsely, abundantly punctate on basal third, punctures gradually finer, sparser toward apex; pubescence yellowish-white, not obscuring integument, distinctly sparser on some irregular areas on distal half; with thick, suberect, dark setae throughout; apex rounded. Legs. Femora with yellowish-white pubescence, except for small, glabrous areas surrounding part of punctures.

Abdomen. Ventrites with yellowish-white pubescence, moderately dense, not entirely obscuring integument, except for small, glabrous areas surrounding punctures laterally; with suberect, thick, dark, sparse setae laterally on ventrites III–V; ventrite V about 1.5 times longer than IV, with apex rounded.

Female. Antennae slightly shorter, 1.55 times elytral length, reaching elytral apex at distal third of antennomere IX. Prosternum with long and erect setae sparser than in male. Ventrite V 2.5 times longer than IV, depressed centrally close to apex; apex truncate.

Variability. Antennomere III mostly brownish; sides of pronotum brown; tibiae mostly brownish; ventral side of metathorax entirely brown.

Dimensions (mm). Holotype male/ paratype males/ paratype females. Total length (including mandibles), 6.40/ 5.31–5.37/6.30–6.85; prothoracic length, 1.30/1.12–1.26/1.20–1.25; anterior prothoracic width, 1.30/1.14–1.23/ 1.40–1.50; basal prothoracic width, 1.40/1.25–1.30/1.40–1.55; largest prothoracic width (between apices of lateral tubercles), 1.80/1.46–1.51/1.80–1.85; humeral width, 2.05/1.87–1.93/2.15–2.20; elytral length, 4.40/3.82–3.85/ 4.50–4.55.

Type material. Holotype male from COSTA RICA, Puntarenas: Osa Peninsula (08º24.273’N / 83º20.265’W; host: Castilla tunu Hemsl. ), 22–28.XII.2013, Li & Lopez col. ( LGBC, to be deposited at CASC) . Paratypes – 1 male, same data as holotype except for 29.XII.2013 –1.IV. , 1 female, same data as holotype, except for 12– 18.I.2014 ( LGBC) ; 1 female, same data as holotype, except for 27.I–8.II.2014 2014 ( MZSP) , 1 male, same data as holotype ( AMNH) .

Etymology. The species name “ setosa ” refers to the long and erect setae on the prosternum.

Remarks. Colombicallia setosa sp. nov. is similar to C. curta Galileo & Martins, 1992 , but differs mainly by the lighter color. Additionally, females of C. curta have no long and erect setae on the prosternum, while these setae are very conspicuous in females of C. setosa .
