Eburodacrys skillmani sp. nov.

( Figures 7–10 )

Description. Integument reddish-brown; distal antennomeres, distal half of elytra, and parts of legs slightly paler; anterolateral tubercles on pronotum black; distal extreme of profemora brown; distal third of mandibles and projections at apex of meso- and metafemora blackish; each elytron with four narrow, longitudinal, yellowish band: three dorsal, and one lateral; tarsal claws brownish. Setae yellowish.

Head. Frons centrally smooth; laterally sparsely, finely punctate; centrally, close to antennal tubercles, finely, abundantly punctate; smooth area with short, very sparse setae; lateral sides with short, moderately abundant setae. Clypeus finely, sparsely punctate; with moderately abundant short setae, interspersed with long, sparse setae. Basal two-thirds of antennal tubercles coarsely, shallowly, confluently punctate; distal third smooth, glabrous; basal twothirds with short, sparse setae. Area between upper eye lobes centrally almost smooth, with sparse setae; laterally finely, abundant punctate, with short, sparse setae. Area between posterior margin of upper eye lobes and anterior margin of prothorax moderately finely, abundant punctate; with short, sparse setae. Area behind upper eye lobes, coarsely, confluently, shallowly punctate; with short moderately sparse setae. Area behind lower eye lobes transversely punctate-striate (fine punctures); with short, sparse setae (very sparse towards anterior edge of prothorax). Genal apex moderately coarsely, confluently punctate (smooth at extreme); with short sparse setae. Gula smooth, glabrous. Submentum smooth; with short, sparse setae, interspersed with long, sparse setae. Mandibles laterally coarsely, confluently punctate at basal two-thirds; with short, sparse setae, interspersed with long, sparse setae. Distance between upper eye lobes equal to 0.45 times length of scape; distance between lower eye lobes, in frontal view, equal to 0.85 times length of scape. Antennae as long as 3.0 times elytral length; reaching elytral apex at distal third of antennomere VI; dorsal surface of scape with longitudinal, deep sulcus; pedicel and antennomeres with long, sparse setae (mainly on pedicel and basal antennomeres); antennal formula based on antennomere III: scape = 0.50; pedicel = 0.13; IV = 0.95; V = 0.98; VI = 1.02; VII = 1.02; VIII = 1.00; IX = 0.95; X = 0.87; XI = 1.22.

Thorax. Prothorax (including lateral tubercles) about as wide as long. Lateral sides of prothorax with conical, moderately large tubercle about middle; area between base and apex of tubercle densely punctate, with moderately abundant, short setae; area between apex o tubercle and anterior margin transversely striate, almost glabrous. Pronotum ( Fig. 10 ) transversely striate-punctate (punctures laterally more distinct); with short, sparse setae, laterally distinctly denser, interspersed with long, sparse setae; anterolateral tubercles conical, very distinct; central tubercle elongate, slightly marked; laterobasal tubercles as central one. Basal half of prosternum punctate, with short, moderately abundant setae; distal half very finely, sparsely punctate, with fine, transverse striae, mainly on anterior third, with short, sparse setae. Prosternal process distinctly enlarged near apex of procoxae. Mesosternal process deeply emarginate at apex. Mesosternum without tubercle. Metasternum laterally pubescent, with short, sparse setae towards middle. Scutellum with short, moderately abundant setae. Elytra. Moderately coarsely, abundantly punctate on basal two-thirds, sparser on distal third; with moderately abundant short setae, interspersed with long, sparse setae on basal third; eburneous maculae elongate; base with single eburneous macula between scutellum and humerus; about middle two eburneous maculae, slightly near each other, the innermost smaller, oblique, starting before base of outermost; apex truncate, with large spine at outer angle and small spine at sutural angle.

Abdomen. Urosternites with sparse, short setae throughout, laterally distinctly denser. Legs. Spiny projection of inner apex of meso- and metafemora very long.

Type material. Holotype male from BOLIVIA, Santa Cruz: 4 km SSE Buena Vista (Hotel Flora & Fauna; 17º29’S / 63º39’W; 300–400 m), 20.X.2011, Skillman and Wappes col. ( MNKM). Paratype female, same data as holotype ( ACMT).

Dimensions in mm (male/female). Total length, 14.7/16.2; length of prothorax at center, 2.8/3.1; largest width of prothorax, 3.3/3.6; anterior width of prothorax, 2.1/2.3; posterior width of prothorax, 2.6/2.9; humeral width, 3.4/3.8; elytral length, 10.0/10.9. The smallest dimensions are those of the holotype.

Etymology. The species is named for Frederick W. Skillman Jr., one of the collectors of the holotype.

Remarks. Eburodacrys skillmani sp. nov. is similar to E. fortunata ( Fig. 11 ), but differs as follows: pronotum distinctly more pubescent; elytra with short setae throughout; lateral sides of prothorax less distinctly striate; and lateral sides of prothorax with short, abundant setae on basal half. In E. fortunata , the pronotum, elytra and lateral sides of prothorax have sparse and long setae, and the lateral sides of prothorax are more distinctly striate. The new species differs from E. monticola mainly by the punctures on basal half of elytra finer (coarser in E. monticola ). See remarks on E. wappesi .

Eburodacrys skillmani can be included in the alternative of couplet “52”, from Martins (1999) (translated):

52’(51). Distance between elytral eburneous maculae on middle of elytra about as wide as one macula. Bolivia... E. skillmani sp. nov. - Distance between elytral eburneous maculae on middle of elytra distinctly smaller than width of one macula............. 52
