Aristotelesia carioca Carvalho

Aristotelesia carioca Carvalho,1947: 257 (orig. descrip.); Eyles, 1971: 942 (list); Schuh, 1995: 5 (cat.).

Diagnosis. This species is distinguished by the black dorsum and contrasting yellow antennae and legs, whereas A. medialis has orange femora (and pale yellow tibiae and tarsi) and head, with only the median line dark, and A. fuscata is uniformly dark, including the legs, with only the antennae pale yellow.

Description. Male holotype (after Carvalho 1947): Length 2.40 mm, width 1.40 mm. Head: Length 0.15 mm (this measurement may be incorrect), width 1.60 mm, interocular width 0.62 mm. Antenna: Segment I length 0.11 mm, II 0.50 mm, III 0.15 mm, IV 0.18 mm. Pronotum: Length 0.60 mm, basal width 1.20 mm.

COLORATION (after Carvalho 1947): Black, covered with golden, hyaline setae; antennae, labium, and legs pale yellow; eyes and ocelli brown; membrane fumate.

STRUCTURE, TEXTURE, AND VESTITURE (after Carvalho 1947, based on combined generic and species description): Form short, convex; densely and coarsely punctate throughout length, covered with short, dense, semierect pubescence, projecting over the membrane and sides. Head: Much wider than long; frons vertical, rounded in front, strongly pilose; eye shape following curvature of head, convex above and concave behind, surpassing lateral margins of pronotum; ocelli prominent, contiguous with inner margin of each eye; vertex slightly carinate; eyes triangular, with apex turned out; antenniferous tubercles situated in a shallow pit in line with inner margin of eyes; eyes reaching only half length of head in lateral view. Pronotum: Convex, posterior angle broadly rounded; collar absent. Mesoscutum: Covered by posterior margin of pronotum. Scutellum: Equilateral. Hemelytron : Embolium not delimited; cuneus horizontal, very narrow; membrane biareolate (one large areole on each hemelytron). Ventral surface: Punctate, with [dense, recumbent] setae; mesosternum prominent, with slight median furrow. Ostiolar evaporative area: Shagreened. Legs: Hind femur much thicker than fore and middle femora; tibia with black setae and denticles; tarsi three-segmented, with joint between II and III barely visible; each claw sickle-shaped, with a slight basal swelling and a sub-apical denticle.

Male genitalia (after Carvalho 1947): Parameres: Symmetrical or nearly symmetrical, with few dorsal bristles. Vesica: With a basal liriform apodeme, an internal chitinous tube (spicule), and a few denticles at the apex.

Female: Unknown.

Distribution. Described from the Federal District, Brazil ( Carvalho 1947) and later reported from Misiones, Argentina ( Carpintero 1996). We here transfer the latter record from Misiones Province to our new species, A. medialis .
