Three new and a known species of Aporcelaimus are reported and described from Alaska, all belonging to the smaller representatives (3 to 5 mm) of the genus. A. boreus sp. nov. resembles A. superbus (de Man, 1880), but it differs by longer spear and spicula, and number and arrangement of male supplements. A. brzeskii sp. nov. differs from species having some of the supplements within the range of spicula by longer body and much longer spicula. A. femineus sp. nov. is characterized by arrangement of pharyngeal gland nuclei, mammillated egg shells and lack of sperm in uterus of gravid females. A. conicaudatus Altherr, 1953 is redescribed, and its taxonomic position discussed. A list of the know terrestrial nematode species in Alaska is added.
