Ectenessa aurantiaca   sp. nov.

( Figs. 1–4 View FIGURES 1 – 13. 1 – 4 )

Holotype male. Integument orange, except for: reddish-brown antennomeres; distal end of antennomeres III –VII blackish; reddish-brown mandibles with black apex; elytra with three longitudinal brown to black bands, noninterconnected at extremes, interspersed with eburneous longitudinal band; tibiae black, with reddish-brown apex; tarsomeres I –II dark-brown; tarsomeres III –V reddish-brown.

Frons and area between antennal tubercles moderately coarse, shallow, sparsely punctate; vertex coarse, abundantly, well-defined punctate, mainly at area near margin of prothorax. Antennal tubercles microsculptured, with fine, sparse punctures; frons with very short setae, interspersed with some long to very long setae on each side near clypeus; vertex with very short setae, interspersed with some long setae. Area behind eye lobes fine, sparsely punctate. Submentum coarsely punctate, shallowly striate, more distinct at sides; with short, sparse setae, interspersed with long setae. Upper eye lobes with four rows of ommatidia; distance between upper eye lobes equal to 0.55 times length of scape; distance between lower eye lobes, in frontal view, equal to 0.7 times length of scape. Antennae as long as 2.5 times elytral length; reaching elytral apex at middle of antennomere VII; antennal formula based on length of antennomere III: scape = 0.62; pedicel = 0.14; IV = 1.02; V = 1.14; VI = 1.07; VII = 1.09; VIII = 0.93; IX = 0.90; X = 0.83; XI = 1.11.

Pronotal disk flattened; coarse, deeply, confluently punctate; lateral callosities well-marked, central region depressed; central callosity distinctly visible, but slightly elevated; setae long, sparse. Prosternum coarse, deeply punctate, with long, sparse setae, except for central area similar to two triangles connected by one of vertices, in which region near to mesosternum is striated, pubescent, and region near to head gradually less striated; with very sparse setae (laterally most distinct), moderately coarse punctate (centrally more agglutinated). Scutellum pubescent. Eburneous bands of elytra, protruding, very narrow at base, distinctly enlarged only after scutellum level; reaching distal third (innermost little shorter); punctures coarse, abundant, finer and sparse at distal third (absent on highest part of eburneous bands); apex obliquely truncate, with triangular projection at external angle, rounded at sutural angle; setae moderately long, sparse. Metasternum laterally microsculptured, with coarse, shallow, sparse punctures; pubescent, with long and sparse setae; most central area with short and sparse setae, interspersed with some long setae.

Femora subclavate; profemora with distinct dorsal keel. Urosternites moderately coarse, sparsely punctate, with sparse, short and long setae.

Female. Antennae as long as 1.9 times elytral length; reaching elytral apex at distal third of antennomere VIII. Antennomeres dark-brown; longitudinal dark bands of elytra interconnected at extremes.

Dimensions in mm (male/female). Total length, 13.1 / 14.5; length of prothorax 2.6 / 2.7; anterior width of prothorax, 1.9 / 2.1; posterior width of prothorax, 1.8 /2.0; humeral width, 2.6 /3.0; elytral length, 8.6 / 10.1.

Type material. Holotype male, BRAZIL, Bahia: Aracatu (“Fazenda Lagoa do Tamburi”; "área da Caatinga arbórea"); 14 º 30.295 ’S / 41 º 27.982 ’W), 21–22.XII. 2012, A. S. Ferreira & L. G. F. Sodré col. ( MZUSP). Paratype female, (14 º 30.959 ’S / 41 º 27.508 ’W; "área de pastagem"), 14–15.XI. 2012, A. S. Ferreira & A. M. M. França col. ( MZUSP).

Etymology. Latin, aurantiaca   = orange; allusive to the color of integument.

Remarks. Ectenessa aurantiaca   differs from E. melanicornis Napp & Martins, 1982   , by the eburneous bands protruding (flat in E. melanicornis   ), and by the dark bands not reaching the base (reaching the base in E. melanicornis   ). It differs from E. guttigera (Lucas, 1859)   as follows: dark tibiae (light in E. guttigera   ); and area around eburneous bands dark (light in M. guttigera   ). It differs from E. affinis Martins, Galileo & Oliveira, 2011   by the dark tibiae (light in E. affinis   ).

In the key to species by Martins (1998), E. aurantiaca   can be included in the couplet " 2 " (modified):
