Abstract

Microlia Casey, 1910 is transferred from the tribe Athetini Casey, 1910 to the tribe Hoplandriini Casey, 1910. The genus Nosora Casey, 1911 is placed in synonymy with Microlia Casey, 1910. Three new species of Microlia are described (M. tetramera Gusarov, sp. nov. and M. pentamera Gusarov, sp. nov. from Costa Rica, and M. panamensis Gusarov, sp. nov. from Panama). Three species are redescribed (M. silacea (Erichson, 1839) known from Virginia and North Carolina, M. azteca (Casey, 1911) known from Mexico, and M. meticola (Casey, 1911) known from Arizona and Texas). A key for identification of species of Microlia is provided. Homalota silacea Erichson, 1839, Nozora azteca Casey, 1911 and N. meticola Casey, 1911 are transferred to Microlia. Dolosota (Microlia) pernix Casey, 1910 is placed in synonymy with Microlia silacea (Erichson, 1839).
