Agaone amazonica sp. nov.

( Figs 1–2 )

Etymology. The name refers to the region where the holotype was collected.

Diferential diagnosis. Agaone amazonica sp. nov. differs from A. notabilis (White, 1855) and A. peruviensis ( Fisher, 1952) , both from Amazonian Region: by the pronotal maculae, which consist of two small crescent-shaped spots near the apex; the scutellum, which is light-yellow in color; and the brown band that surrounds the metafemora which is not connected dorsally to the apical macula. In A. notabilis and A. peruviensis the pronotal macula consists of a single large spot, the scutellum is entirely dark, and the macula that surrounds the metafemora extends dorsally to the apex.

Female ( Fig. 1 ). Integument yellow-orange. Dark brown areas: distal portion of the rostrum; basal 3/4 of the labrum; parts of the palpi; dorsal surface, part of lateral, and entire apical circumference of the scape and antennomeres III–IV; antennomeres V–VII, except basal part of inferior and lateral surfaces (lighter area, gradually smaller from V to VII); apical 2/3 of the antennomere VIII, and a narrow dorsal band that reaches the base; apical half of the antennomeres IX–XI (apical fourth of XI lighter brown); dorsal band of pro- and mesofemora ( Fig. 2 ) that begin close to the base of the club; macula that surrounds the metafemora dorsally projected towards the apex, without reaching it; extreme apex of metafemora; dorsal surface and lateral part of pro- and mesotibiae; pro- and mesotarsi; triangular band on basal third of metepisternum ( Fig. 2 ), that does not reach the base; band with the form of a slanted hourglass laterally on each side of apical half of the metasternum, whose upper part is interconnected to the metepisternal band; extreme apex of urosternite V. Black areas: dorsal surface of the head beyond the eyes, which extends to just beyond the base of the lower ocular lobe; mandibles; sub-reniform macula on each side of pronotal disc, convergent towards the head; elytra ( Fig. 1 ), except elongated macula that just surpass the middle, transverse macula on apical third, and epipleural macula on apical fifth (all pale-yellow); metatibiae and metatarsi. Additionally, there are two small circular maculae on each side of the base of the pronotum that are brownish.

Distance between lower ocular lobes equal to 0.55 times the width of a lobe; distance between upper ocular lobes equal to 1.3 times the width of a lobe. Antennae as long as approximately 1.3 times the elytral length. Rudimentary callosal plate laterally on the prothorax, large, with slightly distinct boundaries, and coarsely and sparsely punctate (almost flat centrally).

Dimensions in mm (female). Total length, 8.7; prothorax: length, 2.0; anterior width, 1.4; posterior width, 1.7; humeral width, 2.2; elytral length, 5.6.

Type material. Holotype female from BRAZIL, Pará: Santarém (Inanu Village; in Malaise trap), 26.XII.1994 -02.0 I.1995, Luiz Aquino col. ( INPA).
