Diagnosis. Members of this genus are distinguished by the elongate-oval body form; the large rounded head, with coarsely faceted, holoptic or nearly holoptic eyes that are often contiguous or separated at the midline in frontal view by no more than the diameter of an ocellus; broad frons; the four to six bristlelike setae on the hind margin of each eye; protruding genae forming wide “cheeks”; long labium extending to middle of abdomen or beyond; short barrel-shaped segment I, and cylindrical antennal segment II, slightly thicker and more pubescent in males than females, and the short, slender, fusiform segments III and IV; usually punctate, trapeziform pronotum with indistinct calli, carinate lateral margins, and a sinuate posterior margin; broadly exposed mesoscutum; equilateral scutellum; entire, moderately laterally convex hemelytra, ranging from uniformly ttranslucent white to dark brown or black, often with white markings; and saltatorial hind femora.

Male genitalia are minimally useful for distinguishing most species of Isometopinae . In Myiomma , the parameres ( Figs. 21–23) are relatively simple; the left paramere is largest, C-shaped, bulbous basally, and slender distally; the right paramere is smaller, more slender, distally acute, and somewhat sword-shaped. The vesica is membranous, lacking sclerotized structures, and has only a simple gonoporal opening. As a consequence, we have refrained from dissecting unique holotypes for this study until more material can be obtained.

Discussion. Previously, 59 species of Myiomma were known worldwide ( Schuh 1995; Herczek 1993; Akingbohungbe 1996, 2003), including 10 from the Western Hemisphere ( Henry 1979, 1984). With the description of seven new species in this paper, 17 New World Myiomma are now known.
