Abstract
    The first zoeal stage of the brackish-water crab Glyptograpsus impressus is described and illustrated from laboratory hatched material. This is the first description of a larval stage from the Central American genus Glyptograpsus which is traditionally placed within the grapsid subfamily Varuninae. Comparison of zoeal setation patterns revealed common features with the Varuninae, while other features are more typical for the Grapsinae and Plagusiinae. Furthermore, zoeae of G. impressus are distinct in the setation of the maxillar endopod, which is unique within the Grapsidae and makes the inclusion of the genus Glyptograpsu within one of the presently recognized grapsid subfamilies questionable.
