RESUMO:

The Family Maeridae comprises 49 genera, with approximately 530 species, being commonly found in tropical shallow waters, showing a high biodiversity along the Brazilian coast. Within Maeridae, the genus Quadrimaera is one of the most representative, with 38 described species typicaly from coral and sandy reefs and intertidal zone. Despite showing a high diversity, both Maeridae and Quadrimaera have never been analysed through a cladistic phylogeny and the relationship between their terminal taxa is poorly known. With this, the present work aimed at proposing a phylogeny for Family Maeridae and for Quadrimaera. For this, specimens were analysed and two data matrices were developed, one for each group. For Maeridae, a matrix with 50 terminal taxa and 145 characters was constructed. Four taxa from Superfamily Hadzioidea were chosen as external groups. For ingroup, 46 genera of Maeridae were included. For Quadrimaera, the data matrix was based in 39 terminal taxa and 78 morphological characters. During the specimens analysis, a new family and new genus of Maeridae were discovered and described. An unique most parcimonious topology was obtained to Maeridae (1309, CI= 37, RI= 19) and three genera previously placed in this family were allocated to different families. Based on this results, the Family Beaudettidae was reestablished. An unique most parcimonious topology for Quadrimaera was also obtained (693, CI = 78, RI = 28) and the genus was corroborated as a monophyletic group based in eight synapomorphies. The species Quadrimaera ascensonis was allocated outside the genus, showing eight synapomorphies and a new genus was described. Taxonomic keys for Quadrimaera, Maeridae and Hadzioidea are provided
