Abstract

The phylogenetic relationships of the alpheid shrimp genera Betaeus Dana, 1852 (15 species) and Betaeopsis Yaldwyn, 1971 (3 species), collectively known as hooded shrimps, are analyzed with morphological, molecular (16S and H3) and combined ?total evidence? (morphology + DNA) datasets. The tree topology resulting from morphological and combined analyses places Betaeus jucundus as sister to all the remaining species of Betaeus and Betaeopsis, rendering Betaeus paraphyletic. On the other hand, Betaeopsis is recovered as monophyletic. Betaeus australis is positioned as sister to the remaining species of Betaeus s. str. (excluding B. jucundus), which is composed of three well-supported and resolved clades. Mapping of biogeographic traits on the combined tree suggests at least two possible historic scenarios. In the first scenario, the North-East Pacific harbouring the highest diversity of hooded shrimps (7 species of Betaeus), acted as the ?Center of Origin?, where species appeared, matured and eventually migrated toward peripheral regions. In the second scenario, Betaeus + Betaeopsis originated in the southern Indo-West Pacific and subsequently colonized the North-East Pacific, where a major radiation involving dispersal/vicariance events took place. The mapping of life history traits (symbiosis vs. free living and gregariousness vs. single/pair living) in the combined tree suggests (1) that different types of symbioses with dissimilar host organisms (sea urchins, abalones, other decapods, spoon worms) evolved independently more than once in the group (in B. jucundus and in various lineages of Betaeus s. str.), and (2) that gregariousness was ancestral in the Betaeus s. str. ? Betaeopsis clade and later shifted toward single/pair living in several lineages.
