A molecular phylogenetic appraisal of the systematics of the Aglaopheniidae (Cnidaria: Hydrozoa, Leptothecata) from the north-east Atlantic and west Mediterranean

Population differentiation or species formation across the Indian and the Pacific Oceans? An example from the brooding marine hydrozoan Macrorhynchia phoenicea

“…Considering these results, the actual number of hydrozoans species may be considerably higher than previously thought. While their rafting ability has been proposed earlier to explain the apparent global distribution of several hydrozoan morpho‐species (Cornelius, , ), inferring distribution ranges of hydrozoans species based on morphology alone might be erroneous as morpho‐species that comprise multiple cryptic species and allopatric lineages are common (e.g., Leclère et al., ; Moura et al., ; Postaire et al., ). In M. phoenicea α, previous phylogeographic analyses using mitochondrial and nuclear markers revealed two divergent lineages, one occurring in the Western Indian Ocean and the other in the Tropical Southwestern Pacific (Postaire et al., ).…”

“…Aglaopheniids’ genus‐level taxonomy is mainly based on the morphology of the reproductive structures (Bouillon et al., ), but as many other characters, life cycles of hydrozoans are subject to convergent or reversible evolution across their phylogeny (Collins, ; Leclère et al., , ; Marques & Collins, ; Miglietta & Cunningham, ) and the diversity of Aglaopheniidae is still under assessment (Moura et al . ; Postaire et al., , ).…”

“…The Aglaopheniidae Marktanner-Turneretscher, 1890 is one of the most species-rich families with more than 250 extant species found in all marine ecosystems (Millard, 1975); they are characterized by the absence of a medusa stage and by the incubation of larvae in dedicated structures, even if some species reacquired a temporally reduced medusa-like stage during their evolution (Leclère et al, 2009;Leclère, Schuchert, & Manuel, 2007). Aglaopheniids' genus-level taxonomy is mainly based on the morphology of the reproductive structures (Bouillon et al, 2006), but as many other characters, life cycles of hydrozoans are subject to convergent or reversible evolution across their phylogeny (Collins, 2002;Leclère et al, 2007Leclère et al, , 2009Marques & Collins, 2004;Miglietta & Cunningham, 2012) and the diversity of Aglaopheniidae is still under assessment (Moura et al 2012;Postaire et al, 2016aPostaire et al, , 2016b.…”

One species for one island? Unexpected diversity and weak connectivity in a widely distributed tropical hydrozoan

“…The Aglaopheniidae family (Marktanner-Turneretscher, 1890) represents one of the largest, with over 250 valid species (Bouillon et al, 2006) and is particularly diversified in tropical marine ecosystems. The diversity of this family is still under assessment, as recent publications highlighted that morphological characters provide little clues to the evolutionary history and species richness of this taxon, presenting extensive cases of morphological convergence and low anagenesis (Leclère et al, 2007;Moura et al, 2012;Postaire et al, 2016a, b). Aglaopheniidae species generally do not have a medusa stage but brood their larvae in dedicated structures of the colony (named gonothecae; Millard, 1975) and planulae are released only when mature (Boero et al, 1992).…”
