Lingafelterellus clarkei sp. nov. ( Figs 1–5 )

Diagnosis. The prothorax yellowish-white, with black macula on center of pronotum, elytra black laterally, gradually dark brown toward suture and apex, and femora distinctly bicolorous distinguish this species.

Description. Female. Vertex and tempora black; frons black laterally, dark reddish-brown centrally; postclypeus dark reddish-brown on large central area, black laterally; mandibles dark reddish-brown on base, black on remaining surface; ventral side of head yellowish-brown except dark brown central area of submentum; mouthparts mostly yellowish-brown with part of palpomeres brown; scape, pedicel and antennomere III black, remaining antennomeres gradually brown toward distal segments; prothorax yellowish-brown, except irregular black macula on center of pronotum, brown transverse area close to distal margin of pronotum (prolonged toward sides of prosternum), brown basal area of pronotum, brownish margins of procoxal cavities, and dark brown prosternal process; ventral side of meso- and metathorax black; abdominal ventrites black with some areas more dark brown; elytra black laterally, gradually dark brown toward suture and apex, with yellowish-brown area on vertical area of base; legs dark brown (almost black) except yellowish-brown femoral peduncles.

Head. Frons with short and moderately long, decumbent setae not obscuring integument, interspersed with long, erect, sparse yellow setae near eyes. Vertex finely, confluently punctate (punctures coarser than on frons), except smooth area centrally close to prothoracic margin; with short, sparse yellow setae interspersed with long, erect, sparse yellow setae laterally. Gulamentum with short and long, moderately abundant erect yellow setae, distinctly not obscuring integument on 2/3 closer to mentum, smooth, glabrous on third close to prothorax. Distance between upper eye lobes 0.8 times length of scape; distance between lower eye lobes in frontal view 0.9 times length of scape. Antennae 0.95 times elytral length; antennal formula (ratio) based on length of antennomere III: scape = 1.27; pedicel = 0.39; IV = 0.94; V = 1.00; VI = 0.89; VII = 0.83; VIII = 0.72; IX = 0.77; X = 0.67; XI = 0.83.

Thorax. Prothorax 1.4 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 from distinctly closed to slightly open behind (apex of hypomeron distinctly reaching apex of prosternal process or only surpassing 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, mesepisternum and metepisternum with grayish-white pubescence partially obscuring integument, interspersed with long, erect yellowish-white setae. Sides of metasternum with decumbent, grayish-white pubescence not obscuring integument, interspersed with long, erect, grayish-white setae; remaining surface with long, erect, sparse grayish-white setae. Scutellum with yellowish-white pubescence partially obscuring integument. Legs. Femora and tibiae with long, erect, sparse yellow setae throughout.

Abdomen. Ventrites I–IV with grayish-white pubescence, not obscuring integument, distinctly denser laterally, interspersed with long, erect, sparse grayish-white setae; ventrite V with sparse grayish-white setae, denser laterally on basal third; apex of ventrite V subtruncate.

Male. It differs from female only by shape of the palpi.

Color variation on males. Head entirely black; antennae mostly dark brown, slightly lighter toward distal segments; pronotal black macula transversely elliptical; elytra mostly reddish-brown (usually with black areas); femoral club dark reddish-brown.

Dimensions (mm) Holotype female/ paratype males. Total length, 6.40/4.90–5.65; prothorax: length, 1.25/1.00– 1.10; anterior width, 0.85/0.70–0.80; posterior width, 0.80/0.65–0.70; widest width, 0.90/0.70–0.80; humeral width, 1.15/1.00–1.10; elytral length, 4.05/3.35–3.85.

Type material. Holotype female from BOLIVIA, Santa Cruz: 5 km SSE Buena Vista (Flora & Fauna Hotel; 17°29’96”S / 63°39’13”W; 440 m; on flying to flowers of “ Ramoneo ”), 11.VIII.2008, R. Clarke & S. Zamalloa col. ( MNKM) . Paratypes – BOLIVIA, Santa Cruz: 1 km W Calendaria village (Hotel Flora & Fauna ; 5 km W Buena Vista; 440 m; on flying to flowers of Gomphrenavaga Mart.), 3 males, 11.VII.2008, R. Clarke & S. Zamalloa col. ( MZSP) .

Etymology. The new species is named for Robin O. S. Clarke, one of the collectors of the type series.

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