Ríos and Duffy, 2007: 13 [?San Blas Islands, as Zuzalpheus brevifrons ]. Remarks. The presence of S. brevifrons in Panama requires confirmation. Ríos and Duffy (2007) first stated that this species is possibly present in San Blas Islands, but after having provided some details about the single ovigerous female from San Blas, the authors concluded that it may represent “yet another undescribed species”. Otherwise S. brevifrons is known only from the Dominican Republic and Belize ( Anker et al. , 2012 ), where it associates with the sponge Aiolochroia crassa (Hyatt, 1875) at depths of 1– 15 m .
