title: Complementary description of Colomerus novahebridensis Keifer (Acari, Eriophyidae), with a discussion about the constitution of the genus and its economic importance, and a tentative key to Colomerus Newkirk & Keifer species.
abstract: Colomerus Newkirk & Keifer, 1971 is an eriophyid genus described by Newkirk and Keifer about 43 years ago, that contains species from all continents, except Antarctica. They live mostly on dicotyledonous plants. Colomerus novahebridensis Keifer, 1977 was described from coconut (Cocos nucifera L., Arecaceae) fruits from Vanuatu. A description of a Thai population of this species is given in this paper. A revised characterization of Colomerus and a dichotomous key for the separation of the species presently considered to belong to this genus are provided, and a consideration about the importance of Colomerus species is presented.
