Abstract
The four zoeal stages and one megalopal stage of Atergatis subdentatus (De Haan, 1835) and Atergatis reticulatus (De Haan, 1835) are described and illustrated, based on laboratory-reared material. The morphological characters of the larvae of these two species are compared with those of six other zosiminid genera (Atergatopsis, Lophozozymus, Platypodia, Platypodiella, Zosimus & Zozymodes) to identify generic diagnostic larval characters.
