Description.

Female. Integument black; apex of palpi and ligula yellowish; anteclypeus reddish. Pubescence yellowish-brown; setae yellowish.

Head. Frons coarsely, deeply, abundantly punctate; with long, moderately sparse setae (longer close to eyes). Area between upper eye lobes coarsely, deeply, abundantly punctate; with long, moderately sparse setae. Area between posterior ocular edge and prothorax with some coarse punctures near posterior ocular edge, smooth toward prothorax; with long, sparse setae. Area behind upper eye lobes densely pubescent close to eye, gradually less dense toward prothorax; without punctures. Area behind lower eye lobes densely pubescent, coarsely punctate, with long, sparse setae on wide band close to eye; glabrous, smooth toward prothorax, except for narrow, longitudinal, finely punctate sulcus between those areas. Antennal tubercles with oblique band of moderately coarsely punctures from base to near apex; with long, sparse setae. Coronal suture not distinct. Gula shiny, smooth, glabrous. Submentum with moderately coarsely, shallowly, sparsely punctate; finely pubescent; with long, sparse setae. Genae pubescent; moderately coarsely, sparsely punctate; with long, sparse setae. Basal two-thirds on outer side of mandibles pubescent interspersed with long, sparse setae. Distance between upper eye lobes 0.6 times length of scape; distance between lower eye lobes, in frontal view, equal to 0.9 times length of scape. Antennae as long as 1.55 times elytral length; reaching elytral apex at base of antennomere X. Scape with long, sparse setae throughout; antennomeres III–XI with long setae ventrally (sparser, shorter toward distal antennomeres); antennomeres III–XI with basal ring with white pubescence, gradually wider toward antennomere XI (almost covering this last one). Antennal formula based on antennomere III: scape = 0.74; pedicel = 0.15; IV = 1.33; V = 1.00; VI = 0.87; VII = 0.77; VIII = 0.72; IX = 0.69; X = 0.69; XI = 0.61.

Thorax. Prothorax about 1.5 times wider than long (including lateral tubercles), distinctly wider at base than anterior margin; lateral tubercles large, conical, placed about middle. Pronotum coarsely, moderately abundantly punctate, except on smooth callosities; with large, transverse, subglabrous band at basal half; remaining surface pubescente; with three callosities: one centrally, longitudinal, on basal half; two laterally, subelliptical, transverse, on anterior half; with moderately short, decumbent setae throughout; with long, sparse setae. Lateral sides of prothorax pubescent, coarsely, moderately abundantly punctate. Prosternum pubescent, coarsely, abundantly deeply punctate on basal half; coarsely, sparsely, shallowly punctate between basal half and anterior third; anterior third subsmooth, except for transverse, narrow carina; with long, sparse setae. Prosternal process narrowed near base, gradually enlarged toward posterior edge of procoxae, strongly enlarged toward apex; moderately coarsely, abundantly punctate on area between procoxae; pubescent; with long, sparse setae. Mesosternum pubescent, except on anterior center; coarsely, densely punctate, except for smooth anterior center; without tubercle. Mesosternal process gradually narrowed toward rounded apex. Metasternum pubescent; coarsely, moderately sparsely punctate, except for central region along metasternal suture; with long, sparse setae. Scutellum distinctly more pubescent laterally than centrally. Elytra coarsely, moderately abundantly punctate throughout; pubescent, interspersed with long, moderately abundant setae throughout; apex rounded.

Abdomen. Ventrites pubescent; coarsely, shallowly, moderately abundant punctate laterally, distinctly sparser centrally; with long, sparse setae; ventrite V with two small, subcircular glabrous areas near apex; apex truncate. Legs. Femora and tibiae pubescent, with moderately coarse, sparse punctures (denser on tibiae).

Dimensions (mm).

Female. Total length (including mandibles), 12.5-9.8; prothoracic length, 2.0-1.9; anterior prothoracic width, 2.2-1.7; basal prothoracic width, 2.4-1.8; largest prothoracic width, 3.3-2.0; humeral width, 3.5-2.9; elytral length, 9.3-7.3.

Type material.

Holotype female, from ECUADOR, Loja: 18.5 km N Gonzanama (48°08 ’08.5” S / 79°23 ’36.4” W), 22.II.2006, F. T. Hovore and I. Swift col. (CAS). Paratypes - 2 females, same data as holotype (LGBC), 1 female, same data as holotype (MZSP).

Etymology.

This species is named for the abundant setae on the elytra, antennae and legs.

Remarks.

Esthlogena (Esthlogena) setosa sp. n. is similar to Esthlogena (Esthlogena) amaliae Galileo & Martins, 2001 (see photo of the holotypes at Bezark 2015), but differs as follows: body wider and distinctly more setose (narrower and less setose in Esthlogena (Esthlogena) amaliae ); elytral punctures finer (distinctly coarser in Esthlogena (Esthlogena) amaliae ); and elytral apex rounded (obliquely truncate in Esthlogena (Esthlogena) amaliae ). It can be separated from Esthlogena (Esthlogena) chicacaoensis Galileo & Martins, 2011 (see photo of the holotypes at Bezark 2015) by the elytral punctures finer (distinctly coarser and more concentrated at base in Esthlogena (Esthlogena) chicacaoensis ), and by the elytral apex rounded (obliquely truncate in Esthlogena (Esthlogena) chicacaoensis ). It can be separated from Esthlogena (Esthlogena) dissimilis Galileo & Martins, 2011 and Esthlogena (Esthlogena) foveolata Aurivillius, 1920 by the central pronotal pubescence not contrasting with pubescence on lateral and basal sides (contrasting in Esthlogena (Esthlogena) dissimilis ), and by the smaller elytral punctures (distinctly larger in Esthlogena (Esthlogena) dissimilis ). It differs from Esthlogena (Esthlogena) guatemalena Bates, 1885 (see photo of lectotype at Bezark 2015) mainly by the denser elytral punctures (distinctly sparser in Esthlogena (Esthlogena) guatemalena ).
