Bebelis tinga sp. nov.

( Figs 26–29 )

Description. Holotype male. Integument mostly dark brown; palpi mostly reddish brown; elytra, dorsal surface of femoral club, part of dorsal surface of tibiae, and most of tarsomeres V dark reddish brown.

Head. Frons moderately coarsely and sparsely punctate; with abundant pale yellow pubescence partially obscuring integument, and white setae interspersed; with one long, erect brown seta on each side close to eyes. Area between antennal tubercles with sculpturing and pubescence as on frons. Remaining surface of vertex and area behind eyes with abundant yellowish-brown pubescence and white setae interspersed, denser behind eyes, especially centrally, except area with sparse pubescence on each side of central region of vertex. Genae finely striate-punctate; with abundant pale yellow pubescence partially obscuring integument, and white setae interspersed, except subglabrous apex toward ventral surface. Postclypeus with sculpturing and pubescence as on frons, except smooth and glabrous apex of sides; with one long, erect brown seta on each side of wide central area. Labrum coplanar with anteclypeus at posterior 3/4, inclined at anterior quarter; with moderately long pale setae directed forward on sides of posterior quarter, and short white setae interspersed; with a few short golden setae on anterior margin. Distance between upper eye lobes 0.22 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.50 times distance between outer margins of eyes. Antennae 1.5 times elytral length, slightly surpassing elytral apex. Scape cylindrical, moderately finely rugose-punctate; with yellow pubescence not obscuring integument, and white setae interspersed; with a few long, erect dark setae ventrally. Pedicel with abundant yellow pubescence not obscuring integument, and long, erect dark setae ventrally. Flagellomeres with abundant pale yellow pubescence, partially obscuring integument, pubescence more yellowish-white basally and apically on III–X, long, erect dark setae ventrally, and moderately long, erect, sparse pale yellow setae throughout. Antennal formula based on length of antennomere III: scape = 0.95; pedicel = 0.24; IV = 1.00; V = 0.76; VI = 0.67.; VII = 0.62; VIII = 0.62; IX = 0.52; X = 0.47; XI = 0.57.

Thorax. Prothorax slightly longer than wide; sides slightly rounded from anterolateral angles to near apex, then subparallel-sided toward posterolateral angles. Pronotum moderately coarsely and abundantly punctate, except rugose-punctate area close to posterior margin; with abundant light yellowish-brown pubescence, distinctly obscuring integument laterally, and short, decumbent white setae interspersed (pubescence slightly sparser on some areas between sides and wide central area, but not forming glabrous longitudinal band); sides of posterior third with longitudinal white pubescent band. Sides of prothorax with light yellowish-brown pubescence obscuring integument, except sparse pubescence on postcoxal process. Prosternum with abundant pale yellow pubescence not obscuring integument. Prosternal process coarsely, sparsely punctate; with yellowish-white pubescence not obscuring integument, denser laterally and apically; narrowest area 0.29 times procoxal width; apex 1.22 times procoxal width. Mesoventrite coarsely, moderately sparsely punctate on wide central area, smooth laterally; with abundant pale yellow pubescence on wide central area, except yellowish-white pubescence close to mesoventral process, glabrous close to mesanepisternum and mesepimeron. Mesanepisternum with light yellowish-brown pubescence obscuring integument, and a few white setae interspersed, pubescence sparser superiorly close to mesoventrite. Mesoventrite with light yellowish-brown pubescence obscuring integument, and a few white setae interspersed. Mesoventral process with abundant yellowish-white pubescence partially obscuring integument; apex 0.36 times mesocoxal width. Metanepisternum with abundant light yellowish-brown pubescence obscuring integument basally, abundant, not obscuring integument on remaining surface. Metaventrite coarsely, sparsely punctate laterally; with abundant light yellowish-brown pubescence not obscuring integument and white setae interspersed laterally, and abundant, both light yellowish-brown and yellowish-white pubescence not obscuring integument centrally. Scutellum with abundant light yellowish-brown pubescence and white setae interspersed laterally, almost glabrous centrally. Elytra. Coarsely, abundantly punctate on anterior third, punctures gradually finer and sparser toward apex; anterior 3/4 mostly with abundant light yellowish-brown pubescence almost obscuring integument, and white setae interspersed, wide, longitudinal white pubescent band laterally about anterior third (apex of this band not distinctly separated from light yellowish-brown pubescence), and dense white pubescence covering sides, from about apex of anterior third to near apex of posterior third, fused on its base with dorsal white pubescent band; posterior quarter with pale yellow pubescence and abundant white setae interspersed; apex subrounded. Legs. Femora striate-punctate; with abundant light yellowish-brown pubescence not obscuring integument, and white setae interspersed (white setae distinctly more abundant laterally). Tibiae with pubescence as on femora, except ventral apex of protibiae with bristly brown pubescence, dorsal sulcus on dorsal surface of mesotibiae and dorsal quarter of dorsal surface of metatibiae with thick, erect brown setae. Dorsal surface of tarsomeres I–III with both yellowish-brown and whitish pubescence not obscuring integument, and tarsomeres IV–V with sparse whitish pubescence.

Abdomen. Ventrites with dense yellow pubescence obscuring integument, and white setae interspersed, except slightly sparser pubescence on central posterior area of ventrites 1–5, and slightly sparser pubescence between sides and central area on posterior region of ventrites 1–4.

Dimensions (mm) (holotype male– paratype male). Total length, 6.55–6.60; prothoracic length, 1.40–1.40; anterior prothoracic width, 1.05–1.10; posterior prothoracic width, 1.20–1,15; maximum prothoracic width, 1.30–1.30; humeral width, 1.50–1.50; elytral length, 4.50–4.50.

Type material. Holotype male from BOLIVIA, Santa Cruz: Florida, 4 km N Bermejo, Refugio Los Volcanes , 18º’06’S, 63º36’W, 1000–1200 m, 25–29.X.2011, Wappes & Skillman leg. ( FSCA) . Paratype male from BOLIVIA, Santa Cruz: 3.7 km SSE Buena Vista, Hotel Flora & Fauna , 430 m, 15–22.XI.2001, B.K. Dozier leg. ( MZSP) .

Etymology. Tupi-Guarani, “tinga”, meaning white; allusive to the white pubescent macula on the elytra.

Remarks. Bebelis tinga sp. nov. is slightly similar to B. maculata Martins & Galileo, 1999 ( Fig. 30 ), but differs as follows: elytra with wide and longitudinal white pubescent band dorsally and laterally ( Figs 26, 28 ); posterior 2/3 of the dorsal surface of the elytra without white pubescent maculae ( Fig. 26 ); and elytral apex subrounded ( Fig. 26 ). In B. maculata , the elytra have narrow and oblique white pubescent band anteriorly, the sides have no wide longitudinal white pubescent band, the posterior 2/3 of the dorsal surface of the elytra has white pubescent maculae, and the elytral apex is strongly projected on outer angle.
