( Figs 36–39 ) Description . Female . Integument mostly dark brown, almost black dorsally; frons (except dark brown area under antennal tubercles), genae, entire central area of vertex, inferior area behind lower eye lobes, gulamentum, and mouthparts reddish brown; basal half of antennomere IV yellow, gradually reddish brown from middle to distal quarter, dark brown in distal quarter; antennomeres V–VI dark reddish brown, dark brown in distal quarter; pronotum with wide dark reddish brown band on each side; central area of prosternum slightly reddish brown; elytron with elongate yellowish brown macula basally, in center of area between humerus and scutellum; pro- and mesocoxae, entire peduncle of meso- and metafemora, basal area of club of profemora, and basal quarter of metafemora yellowish brown. Head . Frons densely micropunctate; with short whitish pubescence not obscuring integument. Light area of vertex with yellow pubescent band, nearly obscuring integument between antennal tubercles and upper eye lobes, gradually narrowed toward prothoracic margin; remaining surface with yellowish brown pubescence, shorter and finer than yellow pubescence, not obscuring integument. Area behind eyes with yellowish brown pubescence exposing integument, gradually whitish toward lower eye lobe; area close to prothorax, behind lower eye lobe, glabrous. Genae with sculpture and pubescence as on frons, except glabrous and smooth distal area. Antennal tubercles densely micropunctate; with whitish pubescence sparser than on frons. Distance between upper eye lobes 0.18 times length of scape; in frontal view, distance between lower eye lobes 0.33 times length of scape. Antennae 2.80 times elytral length, reaching elytral apex at middle of antennomere VI; scape densely micropunctate with long, erect, thick dark setae ventrally; pedicel and antennomeres III–VII with sparse long, erect, thick dark setae ventrally; antennal formula (ratio) based on length of antennomere III: scape = 2.20; pedicel = 0.05; IV = 1.31; V = 1.22; VI = 1.26; VII = 1.34; VIII = 1.40; IX = 1.42; X = 1.37; XI = 1.42. Thorax . Prothorax 1.45 times wider than long; widest area across lateral angles. Pronotum transversely sulcate near base; finely, sparsely punctate in basal area; centrally with wide grayish white pubescent area not obscuring integument; laterally with dense yellow pubescence obscuring integument, longer and thicker than central pubescence. Sides of prothorax with yellow pubescence obscuring integument in narrow area close to pronotum, with grayish white pubescence not obscuring integument of remaining surface (shorter and finer than yellow pubescence). Ventral surface of thorax with grayish white pubescence not obscuring integument. Scutellum with yellowish brown pubescence not obscuring integument. Elytra . Coarsely, abundantly punctate in basal half, gradually finer, sparser toward apex; humeral carina distinct from base (less so near base) to about distal quarter; with three longitudinal carina dorsally, innermost two distinct from base to about distal fifth, outermost less distinct, only present in distal half; apex sinuous, with rounded sutural angle; light area sparsely yellow pubescent; remaining surface with minute yellowish pubescence not obscuring integument; with long, suberect, thick dark setae throughout. Legs . Tibiae proportionally short. Abdomen . Ventrites with grayish white pubescence not obscuring integument. Dimensions (in mm), holotype female . Total length, 7.90; prothoracic length, 1.20; basal prothoracic width, 0.95; distal prothoracic width, 0.75 (0.80 before constriction); greatest prothoracic width, 1.80; humeral width, 2.05; elytral length, 5.70. Type material. Holotype female from BRAZIL , Pará : Taperina [ Taperinha ], July (no additional data), no collector indicated ( MZSP ). Etymology . Named for Eugenio H. Nearns (USDA APHIS, Smithsonian Institution, Washington , DC, USA ), for his friendship and many contributions to our knowledge of the Cerambycidae . Remarks . Piriana nearnsi sp. nov . is similar to P. birai , but differs by: antennomere III distinctly shorter than IV; elytra with elongate yellowish brown macula basally and centrally between humerus and scutellum; elytra with 3 dorsal carina, two innermost more distinct. In P. birai , antennomere III is about as long as IV, lighter colored elongate basal band of elytra includes humerus and extends further distally, and elytra with 2 dorsal carina, innermost less distinct.
