Vitacinis luziae sp. nov.

( Figures 10–13 )

Description. Male. Integument mostly dark brown, almost black; mouthparts dark reddish brown in some areas; anteclypeus dark reddish brown; labrum reddish brown; antennae dark reddish brown, slightly, gradually lighter toward distal segments; trochanters and femoral peduncle yellowish brown; femoral club irregularly variegated with dark reddish-brown areas; pro- and mesotibiae with dark reddish-brown ring centrally; metatibiae with yellowishbrown central ring, gradually darker toward ventral surface.

Head. Frons densely micropunctate, interspersed with fine, sparse punctures; with yellowish-white pubescence (more whitish depending on light intensity) not obscuring integument, whiter, denser close to eyes; with moderately long, erect, sparse dark setae throughout. Area between antennal tubercles and upper eye lobes with a few fine punctures laterally, smooth, depressed, glabrous in diamond central area; with yellowish-brown pubescence on remaining surface, wither close to eyes and margins of glabrous diamond area. Remaining surface of vertex glabrous, with distinct glabrous projection toward area between upper eye lobes each side of central pubescent band. Antennal tubercles densely micropunctate, with pubescence sparser than on central area of frons. Area behind eyes pubescent close to eye, glabrous on wide area close to prothorax, pubescence gradually yellower toward lower eye lobes; with moderately long, erect dark setae behind inferior area of lower eye lobes. Genae with yellowish pubescence not obscuring integument, interspersed with a few moderately long, erect dark setae. Postclypeus transversely divided by narrow carina, with anterior area distinctly lower than posterior one; with yellowish-white pubescence on wide central area, not obscuring integument, interspersed with long, erect dark setae, glabrous laterally. Labrum coplanar with anteclypeus at posterior half, inclined at anterior half; with minute, sparse yellowish-white pubescence, and transverse row of long, erect, dark setae centrally. Gulamentum smooth, glabrous posteriorly, depressed with minute yellowish setae interspersed with a few long, erect brownish setae anteriorly. Distance between upper eye lobes 0.26 times length of scape; in frontal view, distance between lower eye lobes 0.39 times length of scape. Antennae 2.5 times elytral length, reaching elytral apex near apex of antennomere V; posterior third of scape, pedicel, and antennomeres III–VII with long, erect, dark, thick setae ventrally, sparser from IV. Antennal formula (ratio) based on length of antennomere III: scape = 0.85; pedicel = 0.14; IV = 0.86; V = 0.72; VI = 0.65; VII = 0.57; VIII = 0.45; IX = 0.42; X = 0.35; XI = 0.31.

Thorax. Prothorax with narrow, distinct constriction anteriorly. Pronotum coarsely, moderately abundantly punctate along central area, except smooth central gibbosity; coarsely, moderately abundant punctate laterally except nearly smooth anterior third; coarsely, sparsely punctate anteriorly close to margin except smooth central area; coarsely, moderately abundantly punctate on posterior quarter (punctures coarser and deeper than remaining central punctures; forming sinuous two rows); pubescence pale yellow centrally and laterally, slightly yellower anteriorly and posteriorly in central area, except glabrous area close to apex of central gibbosity, yellowish brown between central area and sides except white spot on each side of anterior third. Sides of prothorax nearly smooth; with yellowish-brown pubescence not obscuring integument. Ventral surface of thorax with pale-yellow pubescence not obscuring integument (more grayish-white depending on light intensity). Scutellum with yellowish-brown pubescence on large triangular centrobasal area, with narrow yellowish-brown pubescent band laterally (whiter toward apex). Elytra. Coarsely, moderately abundant punctate (punctures slightly sparser toward apex); pubescence mostly yellowish-brown except irregular, large, oblique yellowish-white band on anterior third, irregular whitish pubescent maculae before midlength (including on inclined area), and irregular yellowish-white pubescent maculae on posterior half, and glabrous basal crests; sides of posterior eight parallel-sided. Legs. Femora with yellowish-white pubescence not obscuring integument, sparser on peduncle; dorsal surface of mesofemora with short, erect, sparse brownish setae. Tibiae with yellowish-white pubescence not obscuring integument, slightly bristly toward apex, except dorsal sulcus of mesotibiae with brownish, dense pubescence; with moderately short, sparse dark setae ventrally.

Abdomen. Ventrites with pale-yellow pubescence not obscuring integument, except glabrous posterior area of I–IV; ventrite V with moderately long, erect setae, distinctly denser posteriorly.

Dimensions (mm). Total length, 10.50; prothoracic length, 1.40; anterior prothoracic width, 1.55; posterior prothoracic width, 1.80; maximum prothoracic width (between apex of lateral tubercles), 2.25; humeral width, 2.75; elytral length, 5.75.

Type material. Holotype male from COLOMBIA, Cesar: Sierra Nevada de Santa Marta (8 km N Pueblo Bello; 10º30’57”N / 73º34’26”W; 2700 m), 13–16.VII.2017, Sinyaev & Pinilla col. ( MZSP).

Etymology. The new species is named after “Luzia”. The woman’s name refers to the skull found in the region of Lagoa Santa ( Brazil, Minas Gerais). This skull is among the oldest human fossils found in America and was recently damaged in the fire which destroyed the MNRJ, but thankfully not lost completely
