( Figs. 34–38)

Myiomma schuhi: Carpintero 1996: 160 (distr.)

Diagnosis. This new species can be distinguished by the narrowly white posterior margin of the eyes ( Fig. 36); the brown antennal segment I and pale antennal segment II; the dark brown to fuscous pronotum with the lateral margin and subapical humeral angle whitish ( Figs. 34, 36); the fuscous propleura with the posterior angle white; and the uniformly pale yellowish-brown legs ( Figs. 34, 35).

Description. Male (holotype): Total length 2.81 mm, maximum width 1.37 mm; cuneus inner length 0.51 mm, width 0.42 mm. Head: Length 0.24 mm, width across eyes 0.60 mm, interocular width 0.12 mm. Antenna: Segment I length 0.13 mm, II 0.80 mm, III and IV missing. Pronotum: Length 0.35 mm, basal width 1.09 mm.

COLORATION: Head: Eyes dark reddish brown; narrow posterior margin white; ocelli ringed with dark reddish brown, more clear centrally; frons, clypeus, interocular area anterior to ocelli, and area posterior to lateral margin of eyes black. Labium: Yellowish brown. Antenna: Segment I dark brown; segment II pale yellowish brown; segments III and IV missing. Pronotum: Propleura shiny fuscous to black, with posterior angle pale or white, apex sometimes tinged with brown. Mesoscutum: Uniformly fuscous to black. Scutellum: Fuscous to black, with only apex pale or white. Hemelytron: Translucent dirty or brownish white, with basal half of clavus darker brown. Ventral surface: Shiny black, with posterior angle white to dirty white; remainder of thorax dark brown to fuscous; abdomen dark brown. Ostiolar evaporative area: Brown; auricle white. Legs: Uniformly pale yellowish brown, hind femora with a weak reddish or yellowish tinge on distal half.

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 four long and one short bristlelike setae; ocelli contiguous with inner margin of eyes, nearly contiguous between, separated by about half the width of an ocellus, set on a low mound only slightly higher than level of eyes ( Fig. 38); frons smooth, with scattered punctures and a few scattered, erect and suberect setae. Labium: Extending to middle of abdomen. Antenna: Segment I barrel-shaped; II, long, cylindrical, weakly bowed, with long, dense, semierect setae subequal to half or more the diameter of the segment; segments III and IV missing. 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 setae. Scutellum: Evenly and finely punctate, transversely rugose, with scattered, recumbent setae. Hemelytron: Weakly convex laterally; with short, dense, semierect, brown setae.

Male genitalia: Male holotype not dissected; abdomen of male paratype missing.

Female: Unknown.

Distribution. Known only from Misiones, Argentina.

Etymology. This species is named pallipes to denote the uniformly pale yellowish-brown legs.

Discussion. We refer Carpintero’s (1996) report of M. schuhi Henry to M. pallipes .
