Two new species of the carabid genus Dolichoctis Schmidt-Göbel from New Guinea and New Ireland are described: D. glabripennis of the striata-group (sensu Baehr, 1999) of the nominate subgenus, from New Guinea, and D. novaeirlandiae of the subgenus Spinidolichoctis Baehr, from the island of New Ireland. In New Guinea, D. glabripennis replaces D. microdera Andrewes of the Greater Sunda Islands and Moluccas that apparently does not occur in New Guinea. D. novaeirlandiae is the first record of a Dolichoctis from this island and it is outstanding due to its very short, only dentate elytra apex
