( Figs 44–50 )

Carterica buquetii Thomson, 1860: 20 ; Gemminger, 1873: 3175 (cat.); Thomson, 1878: 15 (type); Aurivillius, 1923: 457 (cat.); Blackwelder, 1946: 621 (checklist); Gilmour, 1965: 631 (cat.); Monné & Giesbert, 1994: 270 (checklist); Monné, 1995: 23 (cat.); 2005: 337 (cat.); Monné & Hovore, 2006: 234 (checklist); Monné, 2017: 295 (cat.).

Redescription. Integument mostly dark brown but typically black on some dorsal areas; frons from entirely brownish to bicolorous (area closer to antennal tubercles dark brown and distal area reddish brown, both variable in length); genae from reddish brown to brown (narrow distal area always darker); vertex with central reddish brown band or entirely dark brown or black (sometimes with central area slightly lighter); ventral surface of head from light to dark reddish brown; nearly basal half of antennomere IV reddish brown (sometimes dark reddish brown); basal 3/4 of antennomeres V–VI reddish brown, dark reddish brown or segment entirely brown; pronotum without light longitudinal bands; central area of prosternum from reddish brown to entirely brown; peduncle of pro- and mesofemora light reddish brown; basal half of metafemora peduncle reddish brown (sometimes almost entire peduncle); elytra with yellowish brown area variable in shape and size, but always involving humerus: entirely separating basal and distal dark areas dorsally or, more rarely, dark area fused along suture; basal dark macula absent.

Head. Frons densely micropunctate; with short yellowish white pubescence not obscuring integument. Central area of vertex with yellow pubescent band obscuring integument; remaining surface of vertex with yellowish brown pubescence not obscuring integument, shorter and finer than yellow pubescence. Area behind upper eye lobes with yellowish brown pubescence not obscuring integument. Area behind lower eye lobes with moderately large whitish pubescent macula close to upper eye lobe, partially obscuring integument; remaining surface with yellowish brown pubescence not obscuring integument (shorter and finer than whitish pubescence), except yellowish white pubescence close to gena. Genae with sculpture and pubescence as on frons, except glabrous and smooth narrow distal region. Antennal tubercles with sculpture and pubescence as on frons. Distance between upper eye lobes 0.17 times length of scape; in frontal view, distance between lower eye lobes 0.34 times length of scape. Antennae in male 2.65 times elytral length, reaching elytral apex near middle of antennomere VI; in female, 2.58 times elytral length, reaching elytral apex at distal third of antennomere VI; antennal formula (ratio) in male, based on length of antennomere III: scape = 1.72; pedicel = 0.16; IV = 1.07; V = 1.00; VI = 0.96; VII = 0.92; VIII = 1.07; IX = 1.07; X = 0.98; XI = 0.96; antennal formula (ratio) in female, based on length of antennomere III: scape = 1.56; pedicel = 0.13; IV = 1.09; V = 0.98; VI = 0.94; VII = 0.94; VIII = 0.94; IX = 1.07; X = 1.02; XI = 0.89.

Thorax. Prothorax 1.58 times wider than long; widest area ending in acute backward directed spine (sometimes in acute angle directed outward). Pronotum slightly sulcate near base; finely, sparsely punctate in distal 3/4, more abundantly punctate in basal quarter; with wide yellowish brown pubescent area centrally not obscuring integument; with dense yellow pubescence laterally (distinctly whitish basally) obscuring integument (longer and thicker than central pubescence), except narrow area between distal margin and lateral spine with yellowish brown pubescence not obscuring integument. Sides of prothorax with yellowish brown pubescence not obscuring integument. Ventral surface of thorax with grayish white pubescence (more yellowish in some areas), not obscuring integument. Scutellum with yellowish brown pubescence not obscuring integument. Elytra. Moderately finely, abundantly punctate in basal half, gradually sparser toward apex; light areas with yellow pubescence nearly obscuring integument; dark areas with yellowish brown pubescence (shorter and finer than yellow pubescence) not obscuring integument (more grayish white depending on angle of light source). Legs. Femora narrower and shorter in female ( Fig. 50 ) than in male ( Fig. 45 ); with short yellowish brown pubescence not obscuring integument. Tibiae with pubescence as in femora basally, slightly bristly centrally, distinctly thicker, erect and black on distal half.

Abdomen. Ventrites with grayish white pubescence not obscuring integument (more yellowish depending on angle of light source, especially distally).

Dimensions (mm), male/female. Total length, 7.85–8.45/8.00–8.60; prothoracic length, 1.10–1.15/1.10–1.20; basal prothoracic width, 1.35–1.65/1.45–1.60; distal prothoracic width, 1.10–1.25/1.15–1.20 (1.25–1.40/1.30–1.40 before constriction); greatest prothoracic width, 1.75–1.90/1.75–1.95; humeral width, 2.20–2.25/2.10–2.35; elytral length, 5.90–6.40/6.00–6.75.

Remarks. Allocarterica buquetii was described from Brazil, without a locality given. The species is recorded from eastern Brazil, for the first time (Minas Gerais and Santa Catarina), here.
