Myiomma pallidopleura , n. sp.

( Figs. 29–33)

Diagnosis. This new species can be distinguished by the white posterior margin of the eyes; the pale yellow frons ( Fig. 33); the pale antennal segment I with only a narrow, apical, brown band; the dorsally and ventrally pale antennal segment II, with the lateral margins dark brown ( Figs. 29, 32); the dark pronotum, with a narrowly explanate, pale lateral margin ( Fig. 31); the uniformly pale yellow propleura ( Figs. 30, 32); and the pale translucent hemelytra, with only the base of the clavus dark brown ( Fig. 29).

Description. Male (holotype): Total length 2.44 mm, maximum width (spread and twisted; not measured); cuneus inner length 0.37 mm, width 0.42 mm. Head: Length 0.25 mm, width across eyes 0.55 mm, interocular width across ocelli 0.14 mm. Antenna: Segment I length 0.08 mm, II 0.75 mm, III 0.12 mm, IV 0.13 mm. Pronotum: Length 0.40 mm, basal width 1.06 mm.

COLORATION: Head: Eyes dark red to reddish brown; ocelli ringed with red, clear brown centrally; narrow posterior margin pallid or whitish; interocular area anterior to ocelli and area posterior to lateral margin of eyes brown; frons and clypeus pale yellow. Labium: Pale yellow, apical half of segment IV brown. Antenna: Segment I pale yellow, with a narrow brown ring apically; segment II pale dorsally and ventrally, brown laterally; segments III and IV dusky brown. Pronotum: Shiny dark brown to fuscous, with only narrow, explanate, lateral margin clear to whitish. Mesoscutum: Uniformly fuscous. Scutellum: Fuscous , with apex pale yellow. Hemelytron: Pale, translucent, dirty white; basal fourth of clavus, narrow costal margin, and inner margin of cuneus brown; membrane and areole clear. Ventral surface: Pro- and mesopleurae pale yellow; metapleural and ventral areas fuscous; abdomen uniformly fuscous. Ostiolar evaporative area: Whitish; posteriorly dirty white to smoky gray. Legs: coxae pale yellow; femora, tibiae, tarsi, and claws missing.

STRUCTURE, TEXTURE, AND VESTITURE: Head: Eyes nearly contiguous in front, separated by a distance subequal to diameter of an ocellus; coarsely faceted; hind lateral margin with five erect bristlelike setae; ocelli large, contiguous with inner margin of eyes, nearly contiguous with each other, set above eyes on a swollen mound ( Figs. 29, 33); frons strongly transversely rugose, with scattered, short, semierect brown setae. Labium: Folded (if extended, would reach middle of abdomen). Antenna: Segment I, short, barrel-shaped; II, long, cylindrical, bowed through middle; with dense, semierect setae subequal to one half the diameter of segment; III and IV slender, fusiform. Pronotum: Weakly convex, shiny, evenly punctate; calli indistinct; lateral margins nearly straight, carinate, narrowly explanate; posterior margin sinuate through middle; with relatively long, dense, recumbent setae. Mesoscutum: Evenly and finely punctate, with scattered, recumbent brown setae. Scutellum: Transversely rugose, with recumbent and semierect brown setae. Hemelytron: Weakly convex laterally; with relatively short, dense, semierect, brown setae.

Male genitalia: Unique male not dissected.

Female: Unknown.

Etymology. This species is named pallidopleura to denote the uniformly pale yellow or pallid propleural area of the pronotum.

Distribution. Known only from Buenos Aires, Argentina.

Type material. Holotype ♂, Argentina, Buenos Aires, Villa Tesei, June-Sept. 1998, D. J. Carpintero, uvl ( MACN).
