Stizocera lingafelteri sp. nov.

( Figs. 5–8 )

Holotype male. Integument orange-brown (darker on ventral side), except for: head, mandibles, scape, pedicel, distal end of antennomeres III–VII, distal fourth of elytra, distal half of peduncle of femora, femoral club and tibiae black (the latter, lighter towards apex); antennomeres III–XI (except parts mentioned above) dark-brown, gradually shinier towards distal parts; tarsi dark-brown.

Region between antennal tubercles and central area of frons longitudinally striate; dorsal area moderately coarsely punctate, more abundantly between upper eye lobes, with long and sparse setae. Antennal tubercles shiny, almost smooth. Upper eye lobes with four rows of ommatidia; distance between upper eye lobes equal to 0.6 times length of scape; distance between lower eye lobes equal to 0.8 times length of scape. Antennae twice as long as elytral length; reaching elytral apex at distal fourth of antennomere VIII; scape as long as 0.6 times length of antennomere III (without spine), coarse, abundantly, anastomosed punctate; antennomere III with long spine at internal apex; antennomere IV with spine shorter than antennomere III; antennomere V with small spine at internal apex.

Prothorax longitudinal; laterally rounded, without tubercle. Pronotum with four tubercles slightly elevated (two lateroanterior more distinct); central area, between tubercles, fine, transversely striate; lateral area of striae finely punctate; laterally coarse, moderately abundantly punctate; setae long, sparse. Basal two-thirds of prosternum coarse, abundantly, anastomosed punctate; with long, moderately abundant setae. Metepisternum pubescent. Metasternum pubescent at narrow strip along metepisternum, gradually wider towards metacoxal cavities; lateral region coarsely, sparsely punctate, finer, distinctly sparser towards center; area punctate with long setae, gradually shorter towards abdomen. Elytra coarse, abundantly punctate, finer, sparser at distal fourth; surface with long setae, moderately numerous; apex with long spine at external angle and denticle at sutural angle.

Femora clavate; apex of mesofemora with triangular lobes on each side, well-projected; apex of metafemora with external spine longer than inner spine. Urosternites coarse, sparsely punctate (mainly on urosternite I), with sparse, long setae.

Dimensions in mm (male). Total length, 8.3; length of prothorax at center, 1.6; anterior width of prothorax, 1.1; posterior width of prothorax, 1.1; humeral width, 1.6; elytral length, 5.5.

Type material. Holotype male, BRAZIL, Bahia: Aracatu (“Fazenda Lagoa do Tamburi”; "área de Caatinga arbórea"; 14º30.295’S / 41º27.982’W; light trapping), 14–15.XI.2012, A. S. Ferreira & A. M. M. França col. ( MZUSP).

Etymology. The species is named for Steven W. Lingafelter (USNM), for his contribution to the study of Elaphidiini .

Remarks. Stizocera lingafelteri belongs to the group of species without lateral spines or tubercles on prothorax. It differs from S. howdeni Gilmour, 1963 , by the darker antennae, orange-brown pronotum, shorter dark area of the elytra, and mainly by the black femora. In S. howdeni , the antennae are lighter, the pronotum is brown, the dark area of the elytra covers the distal third, and the femora are light. It differs from S. punctatissima Martins, 2005 , S. pantonyssoides Zajciw, 1968 and S. diversispinis Zajciw, 1962 by the darker antennae, black area of elytra longer (except in S. pantonyssoides ), femora mostly black, shorter external spine of apex of the metafemora, and dark tibiae. In these three species, antennomeres are light, femora are mostly orange, apex of metafemora with external spine distinctly longer, and tibiae are light for the most part. In S. punctatissima and S. diversispinis , the dark area of elytra is more distal. It differs from S. delicata Lingafelter, 2004 by the shorter body, dark area of elytra being longer, and sutural apex of elytra with denticle. In S. delicata , the body is more elongate, the dark area of elytra is restricted to the distal end and the sutural spine of elytra is evident. It differs from S. kawensis Galileo & Martins, 2009 by the distinctly shorter spines of antennomeres III–V, apex of mesofemora with triangular lobes of equal length, and shorter spine at external angle of metafemora. In S. kawensis , spines of antennomeres III–V are remarkably long, mesofemora have external spine longer than internal spine, and external spine of metafemora are remarkably long. It differs from S. nigroapicalis Fuchs, 1961 by the dark antennae, orange-brown prothorax, and mainly black legs. In S. nigroapicalis the antennae and legs are red, and the prothorax is black.

Stizocera lingafelteri can be included in the alternative “20” from Martins (2005) (modified) (considering the unicolor antennomeres according to couplet “15”, and black antennae according to couplet “19”):
