New species of Laboulbenia parasitic on leaf beetles

Abstract:

Seven new species of Laboulbenia parasitic on Chrysomelidae from Ecuador are described. These are Laboulbenia calcarata, parasitic on an unidentified host insect of the tribe Metacyclini (Galerucinae); Laboulbenia flexuosa on Percolaspis sp. (Eumolpinae); Laboulbenia gioiae on Gioia sp. (Galerucinae, Alticini); Laboulbenia megascelidis on Megascelis sp. (Megascelinae); Laboulbenia polyxena on Arescus histrio Baly (Cassidinae, Hispini) and on Aceodromus sp. nova (Acarina, Blattisociidae); Laboulbenia sima on Phyllotrupes sp. (Galerucinae, Alticini); and Laboulbenia yasuniensis on Percolaspis sp. (Eumolpinae). Laboulbenia megascelidis is the first record of Laboulbeniales on Megascelinae. The total number of the Laboulbeniales parasitic on Chrysomelidae is raised to 79, of which 66 belong to the genus Laboulbenia.
