Frons finely, abUndantly pUnctate close to clypeal area and lower eye lobes, somewhat coarser, sparser on inverted V-shaped central area; with short, decUmbent, sparse yellowish setae, distinctly more abundant close to lower eye lobes.

Area between antennal tubercles and prothoracic margin moderately coarsely, densely, conflUently punctate with minute, decumbent, sparse yellowish setae interspersed with long, erect yellowish setae. Antennal tubercles gradually minutely punctate toward apex with short, erect, moderately sparse yellowish setae. Coronal suture distinct from clypeus to area between antennal tubercles. Postclypeal area finely pUnctate basally, smooth toward apex; with short, decumbent, sparse yellowish setae on punctate area, interspersed with long, erect yellowish setae, glabroUs on smooth area. LabrUm minUtely, abUndantly punctate basally, smooth toward apex; with long, erect, yellowish setae laterally and brush of yellowish setae on distal margin. OUter edge of mandibles, moderately finely, abUndantly pUnctate on basal 2/3 (pUnctUres, conflUent and oblong); with some long, erect yellowish setae. Area behind lower eye lobes with short, decumbent yellowish setae close to eye; remaining surface with long, erect, sparse yellowish setae. Genae finely, moderately sparsely pUnctate ventrally, finely, densely pUnctate dorsally (somewhat striate close to eye), smooth toward apex; with minute, decumbent, sparse yellowish setae, ventrally interspersed with some long, erect yellowish setae. Gular region smooth close to prothorax, finely, sparsely pUnctate toward sUbmentUm; glabroUs close to prothorax, with short and long, erect, sparse yellowish setae toward sUbmentUm. SUbmentUm finely striate-pUnctate; with short and long, erect, moderately sparse yellowish setae. Distance between upper eye lobes 0.65 times length of scape; distance between lower eye lobes in frontal view 0.55 times length of scape. Antennae 1.2 times elytral length, reaching distal fifth of elytra; ventral side of scape, pedicel and antennomeres III–VII with long, erect, thicK, darK setae, gradUally shorter, sparser toward VII; antennal formUla (ratio) based on antennomere III: scape = 0.82; pedicel = 0.29; IV = 0.70; V = 0.88; VI = 0.76; VII = 0.70; VIII = 0.59; IX = 0.50; X = 0.50; XI = 0.67.

Thorax. Prothorax subcylindrical, 1.2 times longer than wide, laterally slightly rounded. Pronotum coarsely pUnctate-reticUlate,with long, erect, moderately abUndant yellowish setae and slightly conspicUoUs yellowish-white pubescence basally. Sides of prothorax coarsely, abUndantly pUnctate on yellowish area, obliqUely striate on basal reddish-brown area, smoother on distal blacK area; with yellowish-white pUbescence on basal half of yellow area; with short and long, erect yellowish setae except subglabrous distal area. Prosternum coarsely, abundantly punctate on basal half, mostly smooth on distal half; with whitish pubescence interspersed with long, erect, whitish setae on punctate area, glabrous on smooth area. Prosternal process narrowed centrally, notably triangularly expanded toward apex; triangularly depressed, centrally carinate. Mesoventrite centrally with whitish pubescence not obscuring integument, laterally slightly conspicuous. Mesanepisternum, mesepimeron and metanepisternum with whitish pubescence partially obscuring integument, interspersed with long, erect whitish setae. Metaventrite minutely, densely punctate, less dense toward central smooth area, laterally interspersed with fine, moderately abUndant pUnctUres; with whitish pubescence, gradually sparser toward center, interspersed with long, erect whitish setae. Scutellum longitudinally sulcate centrally, mainly after midlength, with minute whitish setae not obscuring integument. Elytra reaching apex of fourth abdominal segment; outer edges convergent from base to slightly after apex of basal third, parallel-sided toward apex; apex slightly obliqUely trUncate, with minUte projection at sUtUral angle; coarsely, pUnctate-reticUlate throUghoUt; with minute, moderately abundant yellowish setae interspersed with long, erect yellowish setae (longer, more abundant on basal third). Legs: apex of metafemora sUrpassing elytral apex. Metatarsomere I 1.45 times as long as II–III together.

Abdomen.Ventrite I minUtely, densely pUnctate laterally, interspersed with fine pUnctUres, smooth centrally; ventrites II– IV minUtely, densely pUnctate interspersed with fine pUnctUres, except smooth center-distal area; ventrite V minUtely, densely pUnctate interspersed with fine pUnctUres, except smooth basal region; laterally with whitish, decumbent, abundant whitish setae (not obscuring integument), interspersed with long, erect whitish setae, gradually sparser toward center (glabrous on center-distal area of ventrite I and basal qUarter of V); apex of ventrite V roUnded.

Dimensions in mm (holotype ♀). Total length (from mandibular apex to abdominal apex), 8.55; prothorax: length, 1.75; basal width, 1.26; distal width, 1.25; widest prothoracic width, 1.45; humeral width, 1.60; elytral length, 5.00.

Type material. Holotype female from BRAZIL, Bahia: Igrapiúna (Reserva Ecológica da Michelin, Pacangê ; 13°50’16.0”S / 39°14’28.9”W; 139 m), 21-22.V.2012, M. Aragão, E. Menezes & E. Mota col. ( MZSP).

Etymology. The name refers to the region where the holotype was collected, popularly known as Costa do Dendê.

Remarks. Eclipta dendensis sp. nov. resembles E. eirene (Newman, 1841) by the metatarsi mostly pale yellow, bUt differs as follows (female): distal antennomeres with basal light ring; pronotUm coarsely pUnctate-reticUlate; distal 2/3 of oUter edge of the elytra parallel-sided; distal third of the elytra not dehiscent; elytra not narrowed toward apex from midlength; elytral apex reaching apex of fourth abdominal segment; apex of metafemora slightly surpassing elytral apex. In E. eirene , the distal antennomeres are not ringed, pronotUm is moderately finely and abUndantly pUnctate, distal 2/3 of outer edge of the elytra is somewhat concave, distal third of the elytra is dehiscent, elytra narrowed toward apex from midlength, elytral apex reaching at about midlength of third abdominal segment (sometimes the apex of third segment and apex of metafemora distinctly surpasses the elytral apex). It also resembles E. thoracica ( Bates, 1873) , bUt differs mainly by the metatarsi mostly pale yellow which is darker in E. thoracica .
