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.caeruleasp. nov. (type locality: Blue Creek, Belize); E.crypticasp. nov. (type locality: 24 km W Piedras Blancas, Costa Rica); E.flavidasp. nov. (type locality: Emerald Pool, Dominica); E.longiventris (Enderlein, 1911) (type species; type locality: Costa Rica); E.maculatasp. nov. (type locality: Xilitla, San Luis Potosi, Mexico); E.marshallisp. nov. (type locality: Guanacaste, Costa Rica); E.mayasp. nov. (type locality: Las Escobas, Guatemala); E.punctatasp. nov. (type locality: Potrerillo, Bolivia); E.tripunctata (Becker, 1916) (type locality: San Mateo, Costa Rica); E.tumescenssp. nov. (type locality: San Esteban, Venezuela); and E.wheelerisp. nov. (type locality: Turrialba, Costa Rica).
Highlights
Enderleiniella was distinguished by previous authors (Becker 1912, Duda 1930) on the basis of the incised lines on the scutum, the absence of the alula, and the reduced anal angle of the wing
The scutal character is consistent, variable in known species, where the incised lines are much clearer in certain species such as E. longiventris but much more subtle in in species like E. tumescens
The incised lines on the scutum are shared with the species-rich and cosmopolitan genus Tricimba Lioy, but the well-developed pronotal carina because of the rounded shape of the back of the head and the distinct postpronotal sulcus of Enderleiniella are absent in species of Neotropical and Nearctic Tricimba that have been examined
Summary
The genus Enderleiniella was proposed by Becker (1912) for the single species Tricimba longiventris Enderlein, 1911. Becker (1916) proposed a second genus, Anoscinella Becker, 1916, for the new species Anoscinella tripunctata Becker, 1916. Duda (1930) considered the two species congeneric and synonymised Anoscinella under Enderleiniella. That synonymy was accepted by subsequent authors
