Aristotelesia fuscata , n. sp.

( Figs. 1–5)

Diagnosis. This species is distinguished by the uniformly fuscous to black body ( Figs. 1, 2) and dark brown legs, with only the antennae pale yellow ( Figs. 4, 5), whereas A. medialis is bluish black, with orange femora and an orange head with a dark median line, and A. carioca is uniformly black with the antennae and legs pale yellow.

Description. Female (n=1; holotype in parentheses): Length 2.87 mm (2.97 mm), maximum width 1.60 mm (1.67 mm). Head: Length 0.60 mm (0.60 mm), width across eyes 1.10 mm (1.26 mm), interocular width 0.65 mm (0.75 mm). Antenna: Segment I 0.14 mm (0.15 mm), II 0.50 mm (0.52 mm), III and IV missing. Pronotum: Length 0.73 mm (0.75 mm), basal width 1.27 mm (1.35 mm).

COLORATION: Head: Silvery brown; ocelli clear with a red internal spot; interocular area, frons, and clypeus uniformly black. Labium: Dark brown. Antenna: Segments I and II brownish yellow; segments III and IV missing. Pronotum: Uniformly shiny black. Mesoscutum: Hidden by posterior margin of pronotum. Scutellum: Uniformly shiny black. Hemelytron: Uniformly shiny black; membrane dirty white, veins fuscous. Ventral surface: Thorax uniformly black; abdomen dark brown to fuscous laterally, fading to paler reddish brown ventrally. Ostiolar evaporative area: Uniformly dark brown to fuscous. Legs: Uniformly dark brown.

STRUCTURE, TEXTURE, AND VESTITURE: Head: Broad; evenly punctate; eyes widely separated, triangular in lateral view; ocelli small, separated from inner margin of eye by the diameter of an ocellus, widely separated from each other by more than two times the dorsal diameter of an eye; interocular area nearly three times the dorsal diameter of an eye; nearly glabrous, with only a few, very short scattered setae distally on frons and juga. Labium: Folded under body, if extended, would reach beyond hind coxae to basal area of abdomen. Antenna: Segment I short, length about two times width; segment II long, gradually thickening to apex, with a few semierect pale setae subequal to half the diameter of the segment; segments III and IV missing. Pronotum: Convex, evenly punctate; calli indistinct; lateral margins straight, carinate; posterior margin evenly convex; glabrous. Mesoscutum: Narrowly exposed from beneath posterior edge of pronotum. Scutellum: Evenly punctate; glabrous. Hemelytron: Convex laterally, embolium not delimited; cuneus very short, transverse, subequal to apical diameter of antennal segment II; evenly punctate; glabrous.

Male: Unknown.

Etymology. This species is named fuscata in reference to the uniformly dark brown or fuscous legs.
