Tese de Doutorado Hirose, G. L., 2009 ABSTRACT:Among the crabs (Ebaliinae) found in Brazil, the genus Persephona is the most representative. At the moment, 4 species were registered: Persephona crinita Rathbun, 1931; P. lichtensteinii Leach, 1817; P. mediterranea (Herbst, 1794) and P. punctata (Linnaeus, 1758). The literature provides many papers for the larvae of Leucosioidea, but for the genus Persephona only one description was made at this moment (P. mediterranea), and the others species still unknown about their larval forms. The purpose of this paper is the description, redescription and morphologic and morphometric comparison between early larval stages of species of the subfamily Eballinae found in the south Atlantic, providing data to assist in the separation and identification of species. The larvae were obtained from ovigerous females of P. mediterranea, P. lichtensteinii and P. punctata, collected in Ubatuba, São Paulo, Brazil (23 º 26'S and 45 º 05'W) by bottom trawls between 10 and 15m depth. The drawings and descriptions made for the larvae (Zoea I), as well all their appendices were made using a microscope Zeiss, equipped with a camera lucida. For morphometric analysis, 15 larvae of each species were measured using a Zeiss microscope, equipped with a image and measure system. Of each larva were taken 8 different morphometric measures (variables), subsequent the data were submitted to a discriminant function analysis. Significantly differences among the species were found in relation with the morphological and morphometric characteristics. These characteristics may help to elucidate the identification of species of Leucosioidea found in the south Atlantic, and can be an important tool in ecological studies, supporting the identification of planktonic morphotypes, which then can be identified at the species level. In general, very little is known, yet, on the larval forms of Leucosioidea from South Atlantic. This lack of information hampers the clarification of taxonomic relationships, which are of fundamental importance for understanding the phylogeny of this group. 88
