Fredlanea birai sp. nov.

( Figs. 1–4 )

Description. Male. Integument black; mouth parts yellowish-brown and dark-brown; base of trochanters yellow; distal area of postclypeus and anteclypeus yellowish-brown; elytra with two large orangish-yellow areas: basal centrally interrupted by brownish band along suture, not reaching the margin laterally; posterior continuous from suture to lateral margin.

Head. Frons finely, sparsely punctate centrally, slightly denser laterally; pubescence very short, sparse, slightly conspicuous from clypeus to level of inferior side of lower eye lobes and centrally; pubescence short, conspicuous, yellowish-brown and whitish laterally between lower eye lobes and antennal tubercles; with long, sparse setae, mainly laterally between lower eye lobes. On each side of area between and close to antennal tubercles and apex of upper eye lobes with conspicuous spot with yellowish-white pubescence; central area between those spots almost glabrous, shiny. Vertex moderately finely, abundantly punctate near upper eye lobes, gradually sparser toward prothoracic margin; pubescence black, slightly conspicuous due to color of integument, slightly grayish on two longitudinal bands laterally; with moderately long, sparse setae. Area behind upper eye lobes moderately finely, sparsely punctate; pubescence black, not dense, slightly conspicuous due to integument color. Area of connection of eye lobes with longitudinal band with yellow pubescence, moderately enlarged toward margin of prothorax. Area behind lower eye lobes moderately coarsely, sparsely punctate; pubescence dark, very short, slightly conspicuous. Genae with dense band with whitish-yellow pubescence close to eye, gradually sparser toward apex; apex glabrous. Antennal tubercles microsculptured, with dark pubescence. Dark area of postclypeus finely, sparsely punctate; with very short grayish pubescence. Labrum smooth basally and distally, coarsely, confluently punctate centrally; with moderately long, abundant setae on punctate area. Distance between upper eye lobes 0.35 times length of scape; distance between lower eye lobes, in frontal view, 0.80 times length of scape. Antennae as long as 1.6 times elytral length, from scape to antennomere X (antennomere XI missing at left antenna; X–XI missing on right antenna); reaching elytral apex at distal third of antennomere VIII. Antennomeres with long, spare setae ventrally. Antennal formula based on antennomere III: scape = 0.55; pedicel = 0.11; IV = 0.66; V = 0.48; VI = 0.42; VII = 0.37; VIII = 0.34; IX = 0.31; X = 0.27.

Thorax. Prothorax 1.25 times wider than long; lateral sides with large, rounded tubercle starting before middle; lateral sides constricted close to base of tubercle, subparallel from apex of tubercle toward anterolateral angle; basal margin sinuous; anterior margin sublinear, slightly emarginate centrally. Pronotum with large central gibbosity on basal half; moderately finely, sparsely punctate, sparser centrally, mainly on gibbosity; with large, longitudinal band with yellow pubescence (whitish on basal quarter), narrowed from base to anterior margin (those bands in continuation with lateral bands of head); area between yellowish bands with dark pubescence, absent in some areas; with long and short, erect, sparse setae. Lateral sides of prothorax moderately coarsely, abundantly punctate; with short, dark-brown pubescence, slightly conspicuous due to color of integument. Prosternum finely, sparsely punctate; with very short, brownish pubescence. Prosternal process narrow at base, gradually enlarged toward apex; pubescence brownish, more grayish depending on angle of light. Mesosternum pubescent (brownish to grayish, depending on angle of light), smooth. Mesepisterna moderately finely, abundantly punctate, smooth toward mesocoxal cavity. Mesepimera impunctate. Metasternum very finely, sparsely punctate; with short, grayish pubescence, denser laterally (more brownish depending on angle of light); with long, very sparse setae. Metepisterna impunctate, with pubescence as on metasternum. Scutellum microsculptured; with very short, whitish, sparse setae; with large, transverse, subelliptical depression centrally (deeper toward central posterior area). Elytra moderately coarsely, abundantly punctate on basal half, gradually finer, sparser toward apex; humeral carina distinct from base to near apex; epipleural carina slightly marked; pubescence whitishyellow on orangish-yellow areas (more whitish on posterior area), dark-brown on black area; with moderately long, sparse setae; distal margin concave, with angles projected (outer angle more distinctly projected).

Abdomen. Ventrites I–IV with short, abundant, yellowish-brown pubescence (more brownish depending on angle of light), slightly longer distally. Ventrite V with pubescence notably sparser than on other ventrites. All ventrites with long, sparse setae.

Legs. Femora with whitish pubescence on ventral surface, gradually sparser toward apex. Metatarsomere I slightly longer than II–III together.

Dimensions (mm). Male. Total length (including mandibles), 11.80; prothoracic length, 1.90; anterior prothoracic width, 2.25; basal prothoracic width, 2.30; largest prothoracic width, 2.40; humeral width, 3.35; elytral length, 8.45.

Type material. Holotype male from ECUADOR, Pichincha: Las Palmeras (1800 m), 14.VII.1987, D. Sanchez col. ( MNRJ).

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

Remarks. Fredlanea birai sp. nov. is similar to F. aequatoria ( Bates, 1881) , but differs as follows: elytral color pattern notably different, with dark area reaching lateral margins; epipleural carina slightly marked. In F. aequatoria the dark area of elytra does not reaches epipleura, and the epipleural carina is notably well-marked.

Fredlanea birai can be included in the alternative of couplet “14”, from Martins & Galileo (2014b) (translated, modified):

14(13). Elytra uniformly orangish-red, without black areas. Colombia, Ecuador............................................ F. hiekei (Fuchs, 1970) - Elytra with black area centrally ............................................................................................................................................ 15 15(14). Black area of elytra reaching epipleural margins; epipleural carina slightly marked. Ecuador..................... F. b i r a i sp. nov. - Black area of elytra not reaching epipleura; epipleural carina notably well-marked. Ecuador... F. aequatoria ( Bates, 1881)
