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. FIGURES 44–48. Myiomma uniformis (holotype). 44, dorsal aspect; 45, lateral aspect; 46, head and pronotum, dorsal aspect; 47, head, lateral aspect; 48, head, frontal aspect. 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.
