Upogebia vasquezi inhabits the western Atlantic in the regions of southern Florida, the Bahamas, Central America and Brazil (from the States of Maranhao to Sao Paulo). Its occurrence has been extended to the coastal region of the State of Para (northern Brazil). There are few descriptions of the larval development of the 116 known species of Upogebia. The present study offers the first description and illustrations of the first two larval stages (zoeas I and II) of U. vasquezi reared in laboratory. The larval features of U. vasquezi were compared with those of two other species of Upogebia, revealing very similar morphological characteristics among species in zoea I. The main variation in this larval stage was in the segmentation of the maxillulary endopod. In zoea II, the number of setae on the scaphognathite was different among some species of Upogebia. The present study contributes to the available literature on the identification of thalassinidean larvae.
