The eggs hatched into pre-zoea and metamorphosed into first zoeas. All the larvae failed to moult into second zoeas. In the present study, both the pre-zoeas and the zoeas of T. tigrina and T. lutea are morphologically described. The pre-zoeas of T. tigrina and T. lutea and the first zoea of T. lutea are morphologically described herein for the first time. The pre-zoeas of both T. tigrina and T. lutea are also morphologically compared with each other and also with their respective first zoeas. The pre-zoeas of both T. tigrina and T. lutea are not morphologically compared with the other pre-zoeas as morphological descriptions of the pre-zoeas of Trapezia spp. are meagre. The first zoeas of different Trapezia spp. are morphologically compared in this paper.
