Abstract

The complete larval stages of Notolopas brasiliensis are described from laboratory reared material, with emphasis on the external morphological features of Majoidea, and compare the morphology of N. brasiliensis with other genera of Pisidae. Larval development of N. brasiliensis consists of two zoeal stages and one megalopa. The duration mean of each zoeal stage was 4.2 ± 1.0 days for Zoea I and 3.8 ± 0.7 days for Zoea II, the megalopa instar appearing 8.1 ± 0.4 days after hatching. The characters previously used to define larval forms of Pisidae are either symplesiomorphic or potentially highly homoplastic. As well, was observed that there are no common sets of larval characters that would define Pisidae nowadays. However, was showed that only a combination of characters could differentiate Notolopas from other pisid genera. (AU)
