Three new species of Laboulbenia from Roland Thaxter’s backlog of slides and a brief review of Laboulbeniales associated with Chrysomelidae

Abstract

Three new species of Laboulbenia parasitic on Chrysomelidae are described from material mounted by Roland Thaxter (1858–1932). These are L. bilobata on Lema spp. from Brazil and Trinidad; L. longipilis from Cameroon; and L. pfisteri on Ivongius sp. from Madagascar. The following species of Laboulbenia on Chrysomelidae are illustrated for the first time: L. macarthurii, L. minuscula, L. nodostomatis, L. obesa, and L. philippina, all of which were described by Thaxter in 1914. A list of all 69 described Laboulbeniales associated with Chrysomelidae is presented in tabulated form.
