C. Godoy et Mw. Nielson, A review of the leafhopper genus Nielsonia Young with descriptions of new species (Homoptera : Cicadellidae : Cicadellinae), J NY ENT SO, 107(1), 1999, pp. 46-54
The genus Nielsonia was established by Young (1977) and included four new s
pecies: praestigia, pretensa, scissa and rostris. In this paper we describe
three new species from Costa Rica: serrata, unica, and pucketti, the latte
r also present in Honduras and Panama. A revised key to all known species,
based on male genitalia, is also presented. The genus ranges from Honduras
(new northern record) to Ecuador.
