Myiomma uniformis , n. sp.

( Figs. 44–48)

Diagnosis. Myiomma uniformis can be distinguished by the narrowly pale hind margin of the eyes ( Figs. 46, 47); the dark brown antennal segment I and mostly dark brown antennal segment II, with the dorsal edge and narrow apex pale; the uniformly dark brown dorsum ( Fig. 44); the dark brown front and middle femora and the partially dark brown hind femur ( Fig. 45) with only the apex pale yellowish brown; and the mostly dark brown tibiae with the apical halves of the front and middle tibiae and the apical one fourth of the hind tibia pale yellowish brown.

Description. Female (holotype): Length 2.33 mm, width 1.30 mm; cuneus inner length 0.43 mm, width 0.35. Head: Length 0.24 mm, width across eyes 0.59 mm, interocular width across ocelli 0.14 mm. Labium: Length 1.22 mm. Antenna: Segment I length 0.11 mm, II 0.58 mm; III and IV missing. Pronotum: Length 0.38 mm, basal width 1.12 mm.

COLORATION: Head: Eyes dark reddish brown, narrow posterior margin and area behind ocelli white; ocelli clear; narrow interocular space and frons black, clypeus slightly paler dark brown or fuscous. Labium: Segment I brown, tinged with red; segments II and III brown; segment IV dark brown. Antenna: Segment I dark brown or fuscous, II dark brown ventrally, paler yellowish brown dorsally; segments III and IV missing. Pronotum: Uniformly dark shiny brown. Mesoscutum: Dark shiny brown, with posterior edges on either side paler brown. Scutellum: Dark shiny brown, with only apex pale yellow. Hemelytron: Uniformly dark shiny brown, including cuneus; membrane translucent smoky brown. Ventral surface: Propleura uniformly fuscous to black; remainder of thorax and abdomen dark brown to fuscous. Ostiolar evaporative area: Dark brown; auricle white on dorsal half, fuscous ventrally. Legs: Coxae and trochanters dark brown; fore and middle femora dark brown with apices narrowly pale, hind femur fuscous with apex pale yellow; fore and middle tibiae pale yellow with basal third of each dark brown, hind tibia dark brown with apical fourth pale yellow.

STRUCTURE, TEXTURE, AND VESTITURE: Head: Eyes nearly contiguous in front, separated by a distance slightly greater than the diameter of an ocellus; hind lateral margin with five erect, bristlelike setae; ocelli large, contiguous with inner margin of eyes, nearly contiguous with each other, separated by about half the diameter of an ocellus, set slightly above eyes on a low mound ( Figs. 46, 48); frons shiny, strongly wrinkled, with a few scattered short, recumbent setae. Labium: Extending nearly to base of ovipositor. Antenna: Segment I short, barrel-shaped; segment II long, slender, gradually enlarging toward apex, with short, sparse, recumbent setae shorter than one fourth the diameter of the segment; segments III and IV missing. Pronotum: Weakly convex, shiny, evenly and deeply punctate; calli indistinct; lateral margins straight, carinate, and narrowly explanate; posterior margin sinuate through middle; with scattered, short, recumbent setae. Mesoscutum: Evenly punctate, with a few short, recumbent setae. Scutellum: Weakly punctate, transversely rugose, with scattered, short, recumbent setae. Hemelytron: Broadly rounded or convex laterally; with short, evenly scattered, recumbent setae.

Male: Unknown.

Etymology. The specific name uniformis is given to denote the uniformly brown dorsum, except for the pale apex of the scutellum.

Host. Beaten from Ruprechtia laxiflora Meisn. [ Polygonaceae ].

Distribution. Known only from Cordoba Province, Argentina.
