Abstract
The genus Enderleiniella Becker, 1912 is revised. The genus is distinguished on the basis of a somewhat flattened head with the inner vertical setae located anteromedially to the outer vertical setae, three lightly incised lines on the scutum, trapezoidal or rectangular scutellum with marginal setae borne on tubercles, reduced alula and anal angle of the wing, and the structure of the male genitalia. The genus contains eleven species in the northern Neotropical and southern Nearctic Regions: E. caerulea sp. nov. (type locality: Blue Creek, Belize); E. cryptica sp. nov. (type locality: 24 km W Piedras Blancas, Costa Rica); E. flavida sp. nov. (type locality: Emerald Pool, Dominica); E. longiventris (Enderlein, 1911) (type species; type locality: Costa Rica); E. maculata sp. nov. (type locality: Xilitla, San Luis Potosi, Mexico); E. marshalli sp. nov. (type locality: Guanacaste, Costa Rica); E. maya sp. nov. (type locality: Las Escobas, Guatemala); E. punctata sp. nov. (type locality: Potrerillo, Bolivia); E. tripunctata (Becker, 1916) (type locality: San Mateo, Costa Rica); E. tumescens sp. nov. (type locality: San Esteban, Venezuela); and E. wheeleri sp. nov. (type locality: Turrialba, Costa Rica).
