Adetus herrerae Santos-Silva & Galileo sp. nov.

( Figs. 1– 4 )

Description

Male. Integument dark-brown, darker reddish-brown on some areas; mouthparts reddish-brown. Pubescence almost entirely obscuring integument, yellowish-white; dorsally with small spots with decumbent white pubescence (mainly on elytra); ventral side with pubescence more whitish centrally (at prothorax, only on prosternal process), interspersed with irregular areas with yellowish-white pubescence.

Head. Frons transverse, finely, sparsely punctate (punctures absent close to clypeus).Vertex finely, sparsely punctate (punctures slightly denser between antennal tubercles and upper eye lobes). Coronal suture distinct from clypeus to posterior level of upper eye lobes. Area behind upper eye lobes with row of fine punctures close to eye. Genae 1.65 times length of lower eye lobes. Labrum almost glabrous centrally, with long, erect setae laterally. Upper and lower eye lobes connected by slender band with ill-formed ommatidia; distance between upper eye lobes 0.95 times length of scape; distance between lower eye lobes in frontal view 1.75 times length of scape. Antennae 0.8 times elytral length, reaching about middle of elytra; antennomeres with short, erect, sparse setae ventrally (close to inner side), gradually sparser toward distal antennomeres; antennal formula (ratio) based on antennomere III: scape = 0.59; pedicel = 0.18; IV = 0.64; V = 0.42; VI = 0.44; VII = 0.42; VIII = 0.39; IX = 0.35; X = 0.34; XI = 0.39.

Thorax. Prothorax as long as wide, wider at base than apically; sides slightly, gradually narrowed on anterior third, with two slightly distinct, rounded tubercles. Pronotum slightly, gradually sloped downward from basal margin to apex of basal third, then distinctly sloped upward to distal margin; finely, sparsely punctate. Prosternal process distinctly sloped upward from prosternum, then gradually sloped downward toward apex. Metasternum finely, sparsely punctate laterally. Elytra. Coarsely, partially confluently punctate on base, gradually finer, sparsely punctate toward apex; surface irregularly, slightly rugose; apex individually rounded. Legs. Apex of dorsal side of tibiae with triangular area sloped downward, almost glabrous on this region that is surrounded by band of short, erect setae. Metatarsomere I 0.7 times length II–III together.

Abdomen. Ventrite V about as long as I (excluding central projection), truncate at apex.
