Compsibidion morrisi sp. nov.

( Figs 13–15 )

Coloration. Integument dark-brown with reddish-brown areas; mouthparts reddish-brown with yellowish-brown areas; base of gula yellowish-brown; antennae gradually reddish-brown toward apex; femora dark reddish-brown; tibiae laterally dark reddish-brown; elytra with yellow maculae: one large, elliptical on basal half; one laterally to former, less distinct and irregular, reaching lateral margin and partially fused do elliptical macula; one large band about middle, obliquely directed toward elytral apex from lateral margin, then curved and obliquely directed toward upward, reaching suture.

Head. Frons finely, densely, confluently punctate throughout; with short, sparse, decumbent setae interspersed with long and very long setae close to eyes. Area between antennal tubercles elevated, obliquely sloping toward vertex; sculpture as on frons; with short, decumbent, sparse setae. Area between upper eye lobes rugose-punctate; with short, decumbent, sparse setae; with one very long seta close to each eye. Area between upper eye lobes and prothoracic margin very finely, densely punctate (punctures coarser, more distinct laterally); glabrous centrally, with short, decumbent, sparse setae laterally. Area behind upper eye lobes finely, densely rugose-punctate; with short, sparse, decumbent setae. Area behind lower eye lobes tumid close to eyes; tumid area moderately coarsely, shallowly, abundantly punctate; remaining surface finely sparsely punctate, mainly toward ventral side; tumid area with long, erect, moderately abundant setae; remaining surface glabrous. Area between lower eye lobes and submentum coarsely, confluently, shallowly punctate; with short, sparse setae interspersed with long, erect setae. Antennal tubercles slightly elevated, with apex rounded; sculpture as on frons; with short, sparse, decumbent setae. Longitudinal sulcus distinct from clypeus to middle of upper eye lobes. Submentum transversely striate-punctate (punctures coarser, denser laterally); with short, sparse setae interspersed with long, erect setae. Genae moderately coarsely, abundantly punctate close to eye, finely, sparsely punctate toward apex (smooth on frontal area); with short, decumbent setae close to eyes, glabrous toward apex. Distance between upper eye lobes 0.45 times length of scape; distance between lower eye lobes in frontal view 0.80 times length of scape. Antennae 1.8 times elytral length, reaching elytral apex at middle of antennomere IX; antennomeres with long, erect, sparse setae (shorter toward antennomere XI); antennal formula (ratio) based on antennomere III: scape = 0.68; pedicel = 0.21; IV = 0.65; V = 0.90; VI = 0.81; VII = 0.82; VIII = 0.71; IX = 0.65; X = 0.53; XI = 0.65.

Thorax. Prothorax 1.5 times longer than wide; laterally slightly rounded. Pronotal disc with five, slightly marked tubercles: two subrounded on each side; one slightly conical placed centrally. Pronotal surface coarsely, sparsely punctate (centrally smooth); pubescent, interspersed with long, erect setae, except for glabrous central area. Sides of prothorax smooth, glabrous on transverse basal band, coarsely, very sparsely punctate, pubescent on remaining area of basal third (smooth and glabrous toward procoxal cavity), finely, sparsely punctate on large central area, interspersed with some coarse punctures and some long, erect setae, slightly transversely striate, with some long setae close to anterior margin. Prosternum smooth, with V-shaped pubescent area on basal half, transversely striate, with short, very sparse setae between middle and anterior quarter, smooth, almost glabrous on anterior quarter. Mesothorax tumid toward mesosternal process; pubescent, but more sparsely toward mesosternal process. Mesepisterna and mesepimera pubescent. Mesosternal process pubescent, with long, erect, sparse setae. Metepisterna pubescent. Metasternum minutely punctate laterally, finely, sparsely punctate toward center; laterally pubescent, with short, sparse setae centrally, with long, erect setae on longitudinal area between sides and center. Scutellum pubescent.

Elytra. Moderately finely and sparsely punctate before elliptical yellow macula and after transverse yellow macula, coarsely, shallowly, abundantly punctate between yellow maculae; with long, erect, sparse setae throughout; outer apical angle with long spine; sutural angle slightly projected.

Legs. Apices of pro- and mesofemora with rounded lobe; apices of metafemora with triangular projection, longer on inner side; femora pubescent interspersed with long, erect setae. Tibiae with long, and very long setae. Metatarsomere I slightly longer than II–III together.

Abdomen. Ventrites I–IV finely, sparsely punctate; ventrite V finely, abundantly punctate; ventrites I–II laterally pubescent, with sparse, short setae centrally (mainly ventrite I), glabrous at apex; ventrite III pubescent, but centrally sparser, glabrous at apex; ventrite IV pubescent, glabrous at apex; ventrite V pubescent on basal half, with sparse, short setae on distal half; ventrites with long, erect, sparse setae (more abundant on distal half of ventrite V); apex of ventrite V slightly rounded.

Dimensions (mm). Total length (including mandibles), 10.80; prothoracic length, 2.25; anterior prothoracic width, 1.30; basal prothoracic width, 1.40; largest prothoracic width, 1.50; humeral width, 2.00; elytral length, 6.70.

Type material. Holotype female from BOLIVIA, Santa Cruz: 4 km SSE Buena Vista (Hotel Fauna & Flora; 17º29’S / 63º39’W; 300–400 m), 22.XI.2013, Skillman & Wappes col. ( MNKM).

Etymology. This new species is named after Roy F. Morris, II, for his friendship and for sending material for study.

Remarks. Compsibidion morrisi sp. nov. differs from C. meridionale Martins, 1969 and C. cleophile (Thomson, 1865) mainly by the apices of mesofemora with rounded lobes, and apices of metafemora with triangular lobes. In these species, the apices of meso- and metafemora are distinctly spiny, mainly at inner side. Compsibidion morrisi sp. nov. can be included in the alternative of couplet “41”, from Martins & Galileo (2007) (translated):
