New species of Laboulbenia from Ecuador, with evidence for host switch in the Laboulbeniales.

Ten new species of Laboulbenia from Ecuador are described. These are L. barraganii, parasitic on Platamops sp. (Salpingidae); L. biformis, parasitic on Diploharpus rossii Moret (Carabidae); L. davidsonii, parasitic on Odontocheila spp. (Carabidae); L. gregaria, parasitic on Philonthus sp. (Staphylinidae); L. micrandra, parasitic on Lobrathium sp. (Staphylinidae); L. mycotreti, parasitic on Mycotretus spp. (Erotylidae); L. opima, parasitic on Chrysodinopsis sp. (Chrysomelidae); L. otongaensis, parasitic on Diploharpus iridescens Moret (Carabidae); L. tapiae, parasitic on Priocera sp. (Cleridae); and L. trogacti, parasitic on Trogactus sp. (Staphylinidae). Laboulbenia barraganii is the first of the Laboulbeniales to be reported on beetles of the family Salpingidae. L. biformis displays a moderate dimorphism associated with the position on the host insect. L. davidsonii, which is very different from the other species of Laboulbenia reported so far on the Cicindelinae but similar to a group of species parasitic on Galerita spp., provides evidence for the occurrence of host switch in Laboulbeniales.
