Lingafelterellus birai sp. nov. ( Figs 6–10 )

Diagnosis. The brown prothorax, without dark macula on pronotum, elytra dark brown, gradually light reddish-brown toward apex, and femora almost entirely reddish-brown distinguish this species.

Description. Male. Head dark brown; prothorax and ventral side of mesothorax brown; metathorax dark reddishbrown; antennae dark reddish-brown, gradually lighter toward apex; elytra dark brown on base, gradually light reddishbrown toward apex; femora reddish-brown, slightly yellowish-brown on base, with some areas slightly darker; abdominal ventrites reddish-brown.

Head. Frons with short, decumbent, yellow pubescence not obscuring integument, interspersed with long, erect, sparse, yellow setae near eyes. Vertex finely, shallowly, sparsely punctate (punctures coarser than on frons, denser between antennal tubercles and upper eye lobes); with short, sparse yellow setae interspersed with long, erect, sparse yellow setae laterally. Gulamentum with short and long, moderately abundant erect yellow setae on striate area, glabrous on area closer to prothorax. Distance between upper eye lobes 0.80 times length of scape; distance between lower eye lobes in frontal view 1.05 times length of scape. Antennae 1.10 times elytral length; antennal formula (ratio) based on length of antennomere III: scape = 1.15; pedicel = 0.38; IV = 1.00; V = 1.15; VI = 1.07; VII = 1.00; VIII = 0.92; IX = 0.92; X = 0.84; XI = 1.15.

Thorax. Prothorax 1.25 times longer than wide. Pronotum finely, sparsely punctate except transversely striate basal area; with yellow pubescence on basal quarter, not obscuring integument, interspersed with long, erect, sparse yellow setae; remaining surface with long, erect, sparse yellow setae. Procoxal cavities open behind (apex of hypomeron reaching at about middle of procoxa). Prosternum minutely, sparsely punctate; finely, transversely striate, mainly on basal 2/3; with short and long, erect, moderately sparse yellow setae throughout (slightly more abundant on basal third). Mesosternum with long, erect sparse grayish-white setae. Mesepimeron and mesepisternum with short and long, grayishwhite setae, slightly denser than on mesosternum. Metepisternum and sides of metasternum with grayish-white, abundant pubescence interspersed with long, erect grayish-white setae; remaining surface of metasternum with long, erect, sparse grayish-white setae. Scutellum with yellowish-white pubescence not obscuring integument, slightly denser distally. Legs. Femora and tibiae with long, erect, sparse yellow setae throughout.

Abdomen. Ventrites with grayish-white pubescence laterally, not obscuring integument, and long, erect, sparse, grayish-white setae throughout; apex of ventrite V truncate.

Female. It differs from male only by shape of the palpi.

Color variation on paratype female. Prothorax, ventral side of meso- and metathorax, antennae, entire elytra and legs dark-brown (femora slightly lighter on base); abdominal ventrites dark reddish-brown, with dark brown areas.

Dimensions (holotype male/ paratype female). Total length, 4.15/5.00; prothorax: length, 0.75/0.95; anterior width, 0.60/0.65; posterior width, 0.55/0.65; widest width, 0.65/0.75; humeral width, 0.75/1.00; elytral length, 3.00/3.50.

Type material. Holotype male ( CASC) and paratype female ( MZSP) from COLOMBIA, Valle del Cauca : 6 miles W Cali (1630 m), 20.III.1955, E. I. Schilenger & E. S. Ross col.

Etymology. The new species is named after the late Ubirajara R. Martins de Souza (Bira).

Remarks. Lingafelterellus birai sp nov. can be separated from L. clarkei sp. n. by the character differences pointed out in the key below.
