Family PORTUNIDAE Rafinesque, 1815

Portunidae is a large family comprising seven subfamilies and 36 genera according to the recent update by Spirodonov (2020). It has been relatively well studied in recent years, based both on morphological analysis and molecular phylogenies (De Grave et al. 2009; Evans 2018, Karasawa et al. 2008; Mantelatto et al. 2018; Schubart & Reuschel 2009; Schweitzer et al. 2010; Spiridonov et al. 2014) and consequently subject of many recent changes.According to Emmerson (2016c), only two subfamilies occur in Mozambique, Portuninae Rafinesque and Thalamitinae Paulson, because he considered Scylla not in the new subfamily Necronectinae Glaessner but in Portuninae.
