( Figures 2 a–e)

Description. Male. Length 6.85 mm (measured from vertex to elytral apices), width 2.40 mm (measured across humeri). Habitus as in Fig. 2a . Head, prothorax, ventral side of meso- and metathorax brown (more dark reddish brown depending on angle of light source); mouthparts yellowish-brown (except brown mandibles); elytra mostly yellowish-brown, except wide, oblique brown band (more dark reddish brown depending on angle of light source) from near humerus to near suture in basal third, brownish band laterally in basal quarter, and wide, subcircular brown band in about central third, not prolonged toward vertical lateral area, gradually lighter, less distinct toward its apex; scape, pedicel and antennomere XI yellowish-brown; antennomere III pale yellow in basal half, gradually light brown toward apex; antennomere IV pale yellow in basal 2/3, gradually light brown toward apex; antennomeres V, VII and IX entirely light brown; antennomeres VI and VIII light brown except brownish apex; antennomere X pale yellow in basal 2/3, yellowish-brown in distal third; femora and tarsi light reddish brown; tibiae yellowish-brown; abdominal ventrites light reddish brown except dark reddish brown apex of ventrites I–IV. General pubescence pale yellow.

Head. Frons finely, sparsely punctate; pubescence abundant, not obscuring integument centrally, nearly obscuring laterally (partially lost in the holotype), except narrow, nearly glabrous band close to eyes. Vertex impunctate; pubescence yellow between antennal tubercles and upper eye lobes, as on frons toward prothoracic margin. Area behind eye lobes with narrow yellow pubescent band close to upper eye lobe, with pale yellow pubescence partially obscuring integument on remaining surface. Antennal tubercles with pubescence as on sides of frons. Median groove distinct from clypeus to prothoracic margin. Genae with sparse pale yellow pubescence except nearly glabrous area close to eye; about as long as half length of lower eye lobe. Distance between upper eye lobes 0.26 times length of scape; in frontal view, distance between lower eye lobes 0.63 times length of scape. Antennae 1.9 times elytral length, reaching elytral apex at basal quarter of antennomere VIII; scape, pedicel and antennomeres III–IV with a few long, erect, thick dark setae ventrally; antennomeres V–X with a few long, erect, dark, thick setae ventrally near apex; antennomere III straight; antennal formula based on antennomere III: scape = 0.95; II = 0.17; IV = 0.81; V = 0.69; VI = 0.63; VII = 0.59; VIII = 0.57; IX = 0.51; X = 0.46; XI = 0.42.

Thorax. Prothorax slightly wider at base, transverse, about 1.25 times as wide as long, sides with rounded lateral protuberance. Pronotum coarsely, sparsely punctate, with two large, slightly distinct gibbosities laterally in central area; pubescence abundant, partially obscuring integument. Sides of prothorax with punctures and pubescence as on pronotum. Ventral side of thorax impunctate; with abundant pubescence not obscuring integument. Narrowest area of prosternal process about 1/7 as wide as procoxal cavity; apex triangular. Mesosternal process slightly, gradually widened toward apex; narrowest area about half as wide as mesocoxal cavity; apex distinctly emarginate centrally. Elytra. Nearly twice as long as width at humeri, about 1.7 times as wide as maximum prothoracic width, about 4.1 times as long as prothoracic length; sides slightly, gradually convergent from humeri to about distal quarter, then rounded toward sutural angle; coarsely, moderately abundantly punctate in large triangular area from base to about middle, sparsely punctate on remaining surface (punctures gradually finer toward apex); humeri prominent, obtuse; pubescence abundant, partially obscuring integument. Legs. Pubescence abundant, not obscuring integument. Meso- and metatarsomeres II–III with a few long, erect, dark, thick setae; metatarsomere I slightly shorter than II–III together.

Abdomen. Pubescence abundant, not obscuring integument; distal area of ventrite V with transverse row of sparse, erect, dark, thick setae; apex of ventrite V truncate, very slightly emarginate centrally.

Female. Unknown.

Type material. Holotype ( Fig. 2 a–e) male from BRAZIL, Amazonas : Reserva Ducke (AM 010, Km 26; Malaise trap), 29.VIII.1978, no collector indicated ( MZSP).

Etymology. This species is named in honor of the first author’s beloved cousin, Roberto Martín “Lole” Pandolfi (Patagonia, Argentina), for his friendship and generosity. The epithet is a noun in the geni- tive case.

Diagnosis and remarks. Lingafelteria pandolfii sp. nov. differs from L. giuglarisi Nearns and Tavakilian, 2012 as follows: antennae thicker, for example diameter of antennomere III equal to about 1/7 of length of antennomere; antennomere III straight; pronotal pubescence not obscuring integument; elytra less distinctly narrowed toward apex (width about base of distal quarter equal to 0.9 times humeral width); elytra with dark bands. In L. giuglarisi antennae slender, for example diameter of antennomere III equal to about 1/9 of length of antennomere; antennomere III slightly sinuous; pronotal pubescence obscuring integument; elytra more distinctly narrowed toward apex (width about base of distal quarter equal to 0.7 times humeral width); and elytra without dark bands.
