Abstract
A new species-group of Lasioseius is described from adults and immatures of four newly described and one undescribed species associated with hispine beetles of the genera Cephaloleia and Chelobasis and other gamasine mites in the furled leaf habitat of Heliconia and related Zingiberales plants. The species-group presents a suite of apomorphic attributes placing it in the subgenus L. (Lasioseius). Adults and immatures were found moving freely on and off the beetles when the latter were exposed from their habitat. Larviparity is indicated by adult females gravid with fully developed larvae. Limited data suggest considerable host specificity between mites and their beetle hosts, indicating that there may be a vast diversity of these mites associated with hundreds of species of hispine beetles in the Neotropical Region. Keys are provided to currently accepted species-groups of Lasioseius and to the species within the new species-group.
