Redescriptions and new host records of chewing lice of the genus Ricinus (Phthiraptera: Ricinidae) from the Neotropical Region

Abstract

Two species of the chewing louse genus Ricinus are redescribed and illustrated: Ricinus dalgleishi Nelson, 1972 from Helmitheros vermivorum (Gmelin, 1789), a new host-louse association, and Ricinus tanagraephilus Eichler, 1956 from Euphonia laniirostris d'Orbigny & Lafresnaye, 1837. Also, new host-louse associations are recorded for Ricinus vireoen-sis Nelson, 1972 from Vireo pallens Salvin, 1863, and for females of an unidentified species of Ricinus sp. from Corytho-pis delalandi (Lesson, 1831), which are described and illustrated.
