Estoloderces obliquus Bezark & Galileo & Santos-Silva 2016, sp. nov.

Estoloderces obliquus sp. nov. (Figs 1–4) Description. Holotype male. Integument dark-brown, except for: mouthparts yellowish; antennomeres III–XI reddish-brown with apex brown; dorsal surface of basal two-thirds of meso- and metatibiae reddish-brown. Head. Frons transverse, coarsely, abundantly punctate; with yellowish-white pubescence (more whitish depending on light), partially obscuring integument; with sparse, moderately long setae close to lower eye lobes, and one very long seta on each side, also close to lower eye lobes. Area between antennal tubercles and upper eye lobes coarsely, moderately abundantly punctate laterally, finer, sparser toward center; pubescence as on frons. Vertex and area behind upper eye lobes with sculpture and pubescence as on frons. Area behind lower eye lobes tumid close to eye, with pubescence shorter, denser than on remaining area; area between tumid region and anterior margin of prothorax moderately coarsely, abundantly punctate. Genae pubescent close to eye, glabrous toward apex. Antennal tubercles finely, densely punctate; pubescence as on frons. Postclypeus narrow, with short, long and very long, abundant setae. Distance between upper eye lobes 0.6 times length of scape; distance between lower eye lobes in frontal view 1.2 times length of scape. Antennae 1.8 times as long as elytral length; reaching elytral apex about distal third of antennomere VIII; pubescence yellowish-white (more whitish depending on light source); with sparse, moderately long setae at ventral side of antennomeres III–X (shorter, sparser toward distal antennomeres); antennal formula based on antennomere III: scape = 0.74; pedicel = 0.18; IV = 1.27; V = 1.14; VI = 1.03; VII = 0.94; VIII = 0.87; IX = 0.78; X = 0.72; XI = 0.60. Thorax. Prothorax transverse, 1.2 times wider than long (including lateral tubercles); with moderately large, subconical tubercle before middle of lateral sides. Pronotum moderately coarsely, abundantly punctate (punctures slightly coarser on anterior third); pubescence dense, yellowish-white, almost entirely obscuring integument, with bands with brown pubescence on basal and anterior thirds (irregular on basal third; narrow, in semicircle on anterior third), and subelliptical brown ring laterally. Lateral sides of prothorax with moderately dense, yellowishwhite pubescence, gradually whiter, denser toward ventral side, becoming broad band with white pubescence, very dense (this band with white pubescence, extends from anterior prothoracic margin to about middle of ventrite III, gradually narrowed toward apex, covering more than half of mesepisternum, all mesepimerum, all metepisternum, lateral side of metasternum, and lateral of ventrites). Prosternum with slightly dense, yellowish-brown pubescence. Prosternal process with yellowish-brown, abundant setae. Mesosternum and mesepisternum (part without white pubescence) with pubescence as on prosternum. Metasternum coarsely, moderately abundantly punctate laterally, gradually sparsely toward center; with wide band with brown pubescence close to lateral white pubescence; remaining surface with yellowish-brown pubescence (more yellowish or whitish depending on light). Scutellum with yellowish-white pubescence. Elytra moderately coarsely, abundantly punctate on basal third, gradually finer, sparser toward apex; pubescence mostly yellowish-brown (more whitish depending on angle of light source), except for: small, oblique band with white pubescence centrally on basal third; lateral sides with white pubescence; distal third with oblique macula with brown pubescence dorsally (wider laterally), followed by subtriangular macula with white pubescence; laterally to the former with irregular macula with brown pubescence; apex obliquely subtruncate. Abdomen. Ventrites with yellowish pubescence (except part with white pubescence laterally on ventrites I– III); apex of ventrite V truncate. Legs. Femora with yellowish-white pubescence. Protibiae with yellowish-white pubescence dorsally and laterally, with dark-brown pubescence ventrally (mainly on distal two-thirds); mesotibiae dorsally with yellowish-white pubescence on basal two-thirds, dark-brown inside dorsal sulcus, yellowish-white laterally and ventrally; metatibiae tumid, with yellowish-white pubescence. Female. Very similar to male, but can be easily differentiated by the metatibiae not being tumid. Color variation (male and female). Mouthparts reddish; tibiae entirely dark-brown; brown pubescence on pronotum slightly distinct; brown pubescence on anterior third of pronotum V-shaped; elytral pubescence more brownish with light maculae of pubescence more yellowish; elytra with narrow, longitudinal band of yellowish pubescence from near apex of oblique anterior band to about middle; elytra with two or three, irregular, maculae with brown pubescence on distal half (not oblique as on holotype); macula with brown pubescence on distal third forming subelliptical ring. Dimensions (mm). Holotype /male/female. Total length, 8.95/7.90–10.6/7.95–10.7; prothoracic length, 1.95/ 1.70–2.20/1.60–2.20; anterior prothoracic width, 1.75/1.50–2.05/1.65–2.15; basal prothoracic width, 1.85/1.65– 2.25/1.55–2.30; largest prothoracic width, 2.25/1.95–2.70/1.90–2.70; humeral width, 2.40/2.05–2.95/2.10–2.90; elytral length, 6.25/5.75–7.90/5.70–7.70. Type material. Holotype male from COSTA RICA, Guanacaste: 3 km SE. R. Naranjo, 5–7.II.1992, F. D. Parker col. (CAS). Paratypes – same locality as holotype, 1 male, 5-7.II.1992, F. D. Parker col. (MZSP); 1 male, 1 female, 3-8.II.1992, F. D. Parker col. (MZSP); 1 male, 1–5.III.1993, F. D. Parker col. (LGBC); 1 female, 18– 28.IV.1993, F. D. Parker col. (LGBC). Etymology. The specific epithet refers to the dark oblique maculae on the elytra. Remarks. Estoloderces obliquus sp. nov. differs from E. luederwaldti as follows: general dorsal color of pubescence distinctly lighter (Fig. 1); anterior band with brown pubescence on pronotum narrow, short and U or Vshaped; prothorax more elongate (1.2 times wider than long). In E. luederwaldti (Fig. 5; see also Bezark 2015), the general dorsal color is distinctly darker, the anterior band with brown pubescence on pronotum is wider, large and transverse, and the prothorax is wider (about 1.45 times wider than long).Published as part of Bezark, Larry G., Galileo, Maria Helena M. & Santos-Silva, Antonio, 2016, Two new species of Lamiinae (Coleoptera: Cerambycidae) from the Neotropical Region, pp. 135-140 in Zootaxa 4085 (1) on pages 135-138, DOI: 10.11646/zootaxa.4085.1.7, http://zenodo.org/record/105252
