Tobipuranga aspera sp. nov.

( Figs. 14–18 )

Holotype male. Integument metallic-green. Scape, femora darker; pedicel, antennomeres III–XI dark-brown; tibiae, tarsi dark-brown with metallic-green reflexes; urosternites orange.

Frons moderately fine, abundantly punctate; between antennal tubercles and pronotal margin coarse, abundantly, punctate, partially anastomosed, mainly on central area between upper eye lobes. Coronal suture wellmarked to level of posterior margin of antennal tubercles. Antennal tubercles contiguous, with acute projection turned backwards; punctures as on frons, slightly sparser. Area under lower eye lobes striate. Mandibles punctatestriate, laterally with short, sparse setae. Gula transversely striate at area closest to the submentum. Submentum punctate-striate. Distance between upper eye lobes equal to 0.6 times length of scape; distance between lower eye lobes, in lower view, equal to 1.4 times length of scape. Length of the antennae equal to 3.8 times elytral length; reaching elytral apex at middle of antennomere VI; scape coarsely punctate; dorsal sulcus of antennomeres III–V well-marked; spine of internal apex of antennomeres III–V conspicuous; antennomere VI with small spine at internal apex; antennal formula based on length of antennomere III: scape = 0.52; pedicel = 0.17; IV = 0.87; V = 1.04; VI = 1.08; VII = 1.10; VIII = 1.04; IX = 1.06; X = 1.06; XI = 1.46.

Pronotum with central longitudinal sulcus well-marked; disk moderately deeply striate; sides coarse, anastomosedly punctate; setae short, erect, dark, moderately abundant (inconspicuous in dorsal view). Prosternum with coarse, deep, abundant sexual punctation at basal three-fourths; anterior fourth abundantly, obliquely striate; with short, moderately abundant setae at area with sexual punctation. Mesosternum fine, densely punctate. Mesepimera coarse, sparsely punctate; coarsely striated. Metepisterna coarse, sparsely punctate at basal two-thirds, except for central, oblique, smooth band; distal third fine, densely punctuate. Metasternum fine, abundantly punctate near metacoxae, gradually coarser, sparser towards apex and at central area; with sparse, moderately long setae. Elytra microsculptured, fine, abundantly punctate; punctures with erect, short, dark setae; apex truncate, with spiny projection at outer angle, and rounded sutural angle.

Femora subclavate; apex of meso- and metafemora with triangular lobe protruding on both sides, apex of metatibia with longer spine at external side. Urosternites coarse, sparsely punctate (mainly on urosternite I); with long, sparse setae.

Female. Antennae 2.0 times as long as elytral length; reaching elytral apex at middle of antennomere VIII. Prosternum entirely transversely striate.

Dimensions in mm (male/female). Total length, 14.0/13.2; length of prothorax at center, 3.1/2.7; anterior width of prothorax, 2.4/2.2; posterior width of prothorax, 2.9/2.6; humeral width, 3.7/3.4; elytral length, 9.0/8.6.

Type material. Holotype male, paratype female, BRAZIL, Bahia: Aracatu (“Fazenda Lagoa do Tamburi”; "área de Caatinga arbórea"; 14º30.961’S / 41º27.512’W; light trapping), 21.XII.2012 (holotype), 22.XII.2012 (paratype), A. S. Ferreira & L. G. F. Sodré col. ( MZUSP).

Etymology. Latin, aspera = rough; allusive to the sculpture on pronotum.

Remarks. Tobipuranga aspera differs from T. longicornis (Bates, 1870) by the slender antennae, spine of antennomere V very conspicuous (with or without spicule in T. longicornis ), prosternum of males with sexual punctation (absent in T. longicornis ), and coarse pronotal sculpture. It differs from T. auripes (Bates, 1870) by the pronotal coarse sculpture, metasternum distinctly finer punctate, and unicolor metafemora (metasternum coarsely punctate, femora bicolor in T. auripes ).

It differs from T. ruficoxis (Bates, 1870) by the metasternum distinctly finer punctate, metacoxae metallicgreen, femora unicolor (metacoxae and basal third of metafemora red-orange in T. ruficoxis ). It differs from T. chlorogaster (Aurivillius, 1910) by the pronotal coarser sculpture, metasternum finely punctate, and orange urosternites (dark in T. chlorogaster ). It differs from T. ignea (Bates, 1870) by the coarser sculpture of pronotum and deepened central longitudinal sulcus of pronotum (very shallow in T. ignea ). It differs from T. auricollis (Dalman, 1817) by the orange urosternites (dark in T. auricollis ) and mesosternum finely punctate. It differs from T. ybyra Napp & Martins, 1996 by the well-defined transverse sulcus of pronotum (slightly conspicuous in T. ybyra ) and metasternum finer punctate.

Tobipuranga aspera can be included in the alternative of couplet "6" (modified) from Napp & Martins (1996):

6(5) Metafemora unicolor ................................................................................. 6a - Metafemora red-orangish at base........................................................................ 7 6a(6) Antennomere V with spicule or unarmed; prosternum in males without sexual punctation. Peru, Brazil (Amazonas)........

............................................................................. T. longicornis (Bates, 1870) - Antennomere V with conspicuous spine; prosternum in males with sexual punctation. Brazil (Bahia)..... T. aspera sp. nov.
