Recchia drechseli sp. n. Figs 7, 8, 9, 10

Description.

Integument dark-brown; basal two-thirds of antennomeres III–XI, mostly metatarsomere I, and basal two-thirds of tarsomeres V reddish-brown; meso- and metatibiae mostly brown.

Head. Frons trapezoidal, microsculptured, moderately fine, abundantly punctate (mainly towards clypeus); pubescence abundant, yellowish-brown, not obliterating integument (slightly whitish on some areas); with long, abundant setae. Antennal tubercles microsculptured, sparse, finely punctate (punctures sparser towards apex); pubescence as on frons. Coronal suture distinct from clypeus to anterior edge of prothorax. Vertex moderately fine, abundantly punctate; pubescence somewhat denser than on frons. Area behind eyes densely pubescent from upper eye lobes to about middle of lower eye lobes; from middle of lower eye lobes to its apex with narrow band of pubescence close to eyes, and glabrous towards anterior edge of prothorax. Genae sparsely pubescent towards eyes, glabrous towards apex. Distance between upper eye lobes equal to 0.3 times the length of scape; distance between lower eye lobes, in frontal view, equal to 0.5 times the length of scape. Antennae as long as 1.9 times the elytral length; reaching elytral apex at base of antennomere VIII; scape and pedicel with long setae throughout; antennomere III with long, moderately abundant setae on ventral side, with moderately short, abundant setae on basal half of dorsal side; antennomeres IV–XI ventrally with long, sparse setae (sparser towards distal antennomeres); antennal formula based on antennomere III: scape = 1.40; pedicel = 0.21; IV = 0.88; V = 0.88; VI = 0.83; VII = 0.81; VIII = 0.74; IX = 0.71; X = 0.62; XI = 0.64.

Thorax. Prothorax cylindrical, slightly longer than wide; lateral sides distinctly narrower at basal third. Pronotum moderately coarse, abundantly punctate (most punctures obliterated by pubescence); pubescence yellowish-white, except for a large “V-like” central area and lateral sides with yellowish-brown pubescence; with long, sparse setae. Pubescence of lateral sides of prothorax yellowish-brown; pubescence close to pronotum, gradually more yellowish-white towards prosternum. Pro- and mesosternum mostly with dark-brown pubescence. Mesepisternum with dark-brown pubescence on half close to mesosternum, yellowish-white on half close to humerus. Mesepimeron with yellowish-white pubescence. Metepisternum and lateral sides of metasternum with dense, yellowish-white pubescence; remaining surface of metasternum with pubescence less dense. Elytra: coarse, abundantly punctate on basal third, gradually finer, sparser towards apex; pubescence yellowish-white (more yellowish on some areas), not forming distinct drawing; with long, sparse setae; apex individually rounded. Legs: pubescence on femora distinctly not obliterating integument.

Abdomen. Ventrites with yellowish-brown pubescence, interspersed with long, sparse setae. Ventrite V trapezoidal, 1.4 times as long as IV; apex rounded.

Type material.

Holotype male: PARAGUAY, Canindeyú: Armisticio (54°32'W, 24°34'S), 30.XI.2009, U. Drechsel col. (MZSP).

Dimensions in mm (male).

Total length, 11.6; length of prothorax at center, 1.9; anterior width of prothorax, 1.9; posterior width of prothorax, 1.9; humeral width, 2.7; elytral length, 8.3.

Etymology.

The species is named for Ulf Drechsel, collector of the holotype.

Remarks.

Recchia drechseli sp. n. differs from Recchia goiana Martins & Galileo, 1985 as follows: dorsal pubescence less compact; upper eye lobes wider (Fig. 10), largest width larger than basal width of scape; distance between upper eye lobes equal to about 2.3 times the largest width of one lobe. In Recchia goiana the dorsal pubescence is more compact, the upper eye lobes are narrower (Fig. 11), with largest width about as wide as basal width of scape, and the distance between upper eye lobes is equal to 3.0 times the largest width of one lobe. It differs from Recchia flaveola Martins & Galileo, 1985 mainly by the femora being darker (reddish in Recchia flaveola ), and by the elytra without distinct contrasting areas of pubescence (present in Recchia flaveola ).

Recchia drechseli can be included in the alternative of couplet “19”, from Martins and Galileo (1998) (translated; modified):
