Eburodacrys wappesi sp. nov.

( Figures 4–6 , 12 )

Description. Integument orange-brown; distal two-thirds of elytra slightly paler; lateral tubercles of prothorax and anterolateral tubercles on pronotum black; central tubercle on pronotum brown; apex of profemora brown; distal third of mandibles and projections at apex of meso- and metafemora blackish; tarsal claws brownish; small brown macula at apex of anterior eburneous macula of elytra; brownish around posterior eburneous maculae of elytra (mainly anteriorly).

Head. Frons coarsely, shallowly, confluently punctate; with short, sparsely, yellowish setae, interspersed with sparse long setae. Centro-basal half of clypeus with sculpture as on frons, centrally almost glabrous, laterally with short, sparse setae; distal half and lateral more distinct, abundantly punctate, setae as on frons, with one very long setae on each side. Basal two-thirds of antennal tubercles with sculpture and pubescence as on frons; distal third smooth, glabrous. Vertex with sculpture shallower, sparser than on frons (almost smooth between upper eye lobes); setae shorter, sparser than on frons. Area behind upper eye lobes shallowly punctate; with short, yellowish setae. Area behind lower eye lobes transversely punctate-striate towards anterior margin of prothorax; with short, sparse, yellowish setae. Genal apex almost smooth, with short yellowish setae, interspersed with long and very long setae, glabrous, smooth towards apex. Gula smooth, almost glabrous. Submentum shallowly punctate; with short, sparse, yellowish setae, interspersed with very long, sparse, yellowish setae. Mandibles laterally with short, long and very long setae (the latter at basal third). Distance between upper eye lobes equal to 0.40 times length of scape; distance between lower eye lobes, in frontal view, equal to 0.85 times length of scape. Antennae as long as 2.3 times elytral length; reaching elytral apex at apex of antennomere VII; dorsal surface of scape with longitudinal, deep sulcus; pedicel and antennomeres with long, sparse, yellowish setae (mainly on pedicel and basal antennomeres); antennal formula based on antennomere III: scape = 0.61; pedicel = 0.13; IV = 0.83; V = 0.84; VI = 0.84; VII = 0.81; VIII = 0.81; IX = 0.73; X = 0.69; XI = 0.85.

Thorax. Prothorax (including lateral tubercles) 1.3 times wider than long. Lateral sides of prothorax with conical, large tubercle about middle. Pronotum ( Fig. 12 ) distinct, transversely striate; laterally not distinctly punctate; with short, sparse, yellowish setae, interspersed with long, sparse setae; anterolateral tubercles conical, very distinct; central tubercle elongate, not very distinctly raised; laterobasal tubercles as central one. Basal twothirds of prosternum transversely striate, with short, sparse, yellowish setae (more abundant towards procoxal cavities); anterior third finely, transversely striate, with coarse, shallow punctures. 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 centrally with short, sparse, yellowish setae. Elytra. Moderately coarsely, abundantly punctate on basal two-thirds, sparser on distal third; with short interspersed with long, sparse, yellowish setae; eburneous maculae elongate; base with single eburneous macula between scutellum and humerus; about middle two eburneous maculae, near each other, the innermost smaller, starting before base of outermost; apex truncate, with large spine at outer angle and small spine at sutural angle.

Abdomen. Urosternites with sparse, short, yellowish 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), 17.X.2011, Skillman and Wappes col. ( MNKM). Paratype male same data as holotype, except for 20.X.2011 ( ACMT).

Dimensions in mm (male). Total length, 14.7–21.5; length of prothorax at center, 2.8–4.0; largest width of prothorax, 3.3–5.0; anterior width of prothorax, 2.1–3.5; posterior width of prothorax, 2.6–4.1; humeral width, 3.4– 5.7; elytral length, 10.0–14.7. The smallest dimensions are those of the holotype.

Etymology. The species is named for James E. Wappes (ACMT), for his friendship and constant help with specimens to study.

Remarks. Eburodacrys wappesi sp. nov. is similar to E. skillmani sp. nov., but differs as follows: vertex with short, sparse setae; central tubercle of pronotum distinct ( Fig. 12 ); pronotum with very sparse setae; lateral tubercle of pronotum conical, large; eburneous maculae of middle area of elytra near each other; elytra with short, sparse setae interspersed with long, sparse setae throughout. In E. skillmani the setae on vertex are distinctly more abundant, the central tubercle of pronotum is not distinct ( Fig. 10 ), the pronotum has setae distinctly more abundant, the lateral tubercle of pronotum is smaller, the eburneous maculae of middle area of elytra are more spaced from each other, the elytra has not long setae throughout, and has distinctly more abundant pubescence. Eburodacrys wappesi sp. nov. can be separated from E. fortunata Lameere, 1884 ( Fig. 11 ) by the distinct, brownish central tubercle on pronotum (less raised, not brownish in E. fortunata ), and by the eburneous maculae of middle area of elytra more near each other and with different size (more distant each other and about same length in E. fortunata ). It also differs from E. raripila Bates, 1870 mainly by the mesosternum without tubercle (with tubercles in E. raripila ). and E. monticola Monné & Martins, 1973 mainly by the punctures on basal half of elytra finer (coarser in E. monticola ).

Eburodacrys wappesi can be included in the alternative of couplet “58”, from Martins (1999) (translated; modified):

58(55). Outermost eburneous macula of the central region of the elytra twice as long as innermost.......................... 58’ - Outermost eburneous macula of the central region of the elytra as long as innermost or just longer.................... 59 58’(58). Mesosternum with tubercle; metafemora surpassing elytral apex. French Guiana, Peru, Bolivia, Brazil (Mato Grosso).......

.................................................................................. E. raripila Bates, 1870 - Mesosternum without tubercle; metafemora not reaching elytral apex. Bolivia...................... E. wappesi sp. nov.
