Three species (<em>Buchnerillo neotropicalis, Hawaiioscia nicoyaensis </em>and<em> Trichorhina biocellata</em>) are described as new and two species (<em>Tylos niveus</em> and <em>Armadilloniscus</em> cf. <em>caraibicus</em>) are newly recorded from the country. The poorly known species <em>T.</em> <em>niveus</em> is also illustrated. At present the total number of terrestrial isopod species recorded from Costa Rica is 30. Interestingly four typical littoral halophilic species (<em>Ligia</em> <em>baudiniana</em>, <em>Tylos</em> <em>wegeneri</em>, <em>T.</em> <em>niveus</em> and <em>A. </em>cf.<em> caraibicus</em>) are present on both the Pacific coast of Costa Rica and on the coasts of the lands encompassed by the Caribbean Sea. With the sole exception of <em>A.</em> cf. <em>caraibicus</em>, no morphological differences could be detected from the Pacific and Caribbean populations of those species. Rev. Biol.
