Three species, Podmosta delicatula (Claassen), P. obscura (Frison) and P. weberi (Ricker), are described in detail for the first time. A preliminary larval key to the five North American species is presented, based mainly on differences in pigment pattern and cercal setation. Separation of the larvae of non-gilled nemourid genera Ostrocerca and Podmosta, though difficult, is further clarified by comparative scanning electron micrographs of the four western Nearctic Podmostaspecies and larvae of Ostrocerca dimicki (Frison)TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaPrirodoslovni muzej Slovenije
