Myiomma binotata , n. sp.

( Figs. 24–28)

Diagnosis. Myiomma binotata most closely resembles M. argentinensis in having a uniformly fuscous pronotum, propleura, antenna, and femora ( Fig. 25), but differs in possessing a more whitish hemelytron with the apical half of each cuneus and a distinct apical spot on the corium fuscous ( Fig. 24), a longer more slender antennal segment II, and a proportionately broader pronotum (in relation to the head width), whereas M. argentinensis has a more yellowish-white hemelytron with only the base of the clavus infuscated, a shorter thicker antennal segment II, and a proportionately narrower pronotum.

Description. Male (holotype): Length 3.26 mm, width 1.15 mm; cuneus inner length 0.48 mm, width 0.30 mm. Head: Length 0.18 mm, width 0.43 mm, interocular width across ocelli 0.14 mm. Labium: Folded and obscured under body on card. Antenna: Segment I length 0.08 mm, II 0.75 mm, III 0.14 mm, IV 0.09 mm. Pronotum: Length 0.37 mm, basal width 1.20 mm.

COLORATION: Head: Eyes dark reddish brown, narrow posterior margin white; ocelli dark red; narrow interocular area, frons, and clypeus black. Labium: Fuscous to black. Antenna: Segments I and II fuscous to black, apex of II slightly paler; segments III and IV brown. Pronotum: Uniformly shiny black. Mesoscutum: Shiny black. Scutellum: Shiny black, apex pale yellowish white. Hemelytron: Translucent, white to dirty white, with basal fourth of clavus, narrow costal margin, a spot at apex of corium and outer margin and apical half of cuneus dark brown; membrane and areole clear. Ventral surface: Thorax, including propleura, and abdomen uniformly shiny black. Ostiolar evaporative area: Dark brown; auricle white on dorsal knob, remainder dark brown. Legs: Coxae dark brown; fore femur dark brown, fore tibia with basal third dark brown, middle third brown, and distal third pale yellow; middle and hind legs missing.

STRUCTURE, TEXTURE, AND VESTITURE: Head: Eyes nearly holoptic in front, separated by a distance subequal to the diameter of an ocellus, hind lateral margin with a row of five erect, bristlelike setae; ocelli large, contiguous with inner margin of each eye, nearly contiguous with each other, set on a swollen mound ( Figs. 26, 28); frons coarsely wrinkled, with a few scattered, erect to semierect, brown setae, especially on lower half. Labium: Folded (if extended, would reach onto middle of abdomen). Antenna: Segment I short, barrel-shaped; II thickened, thicker than diameter of fore tibia, weakly bowed, with short, dense, semierect, dark brown setae, length subequal to about one third diameter of segment; III and IV short, slender, with a few long, semierect setae. Pronotum: Weakly convex, evenly punctate; calli indistinct; lateral margins weakly rounded, carinate, narrowly explanate, widening posteriorly; posterior margin sinuate through middle; with dense, recumbent brown setae. Mesoscutum: Evenly and finely punctate, with recumbent brown setae. Scutellum: Equilateral , transversely rugose, with recumbent brown setae. Hemelytron: Weakly convex to to nearly straight, with dense, semierect brown setae.

Male genitalia: Unique male not dissected.

Etymology. This species is named binotata to denote the two brown hemelytral spots, one at the apex of each corium.

Distribution. Known only from La Pampa Province, Argentina.

Type material. Holotype ♂, Argentina, La Pampa, S[an]ta. Rosa, at light, 13 Dec. 2010, [D. L.] Carpintero ( MACN).
