The type series of Poromitra crassiceps (Pisces, Melamphaidae) with lectotype designation

The type series of Poromitra crassiceps (Günther, 1878) was thought to include specimens from four localities in the Atlantic, Pacific, and Southern oceans. Comparison of the extant syntypes with the original description revealed that the specimen from the Pacific Ocean was not included in the original type series; one syntype from the Atlantic Ocean was never incorporated into the collection of the Natural History Museum, London, and is considered lost, and another cannot be identified due to its bad condition. The fourth syntype, from the Southern Ocean and in the best condition, is designated lectotype of this species. Molecular analysis of tissue samples collected by us as well as publically available COI sequences showed that only one species, P. crassiceps, is currently known from the Southern Ocean. Specimens from this ocean named P. atlantica (Norman, 1929) in the literature and in collections are probably misidentifications of P. crassiceps. The validity of P. atlantica needs confirmation from fresh material from the type locality

Integrated Taxonomy Reveals Hidden Diversity in Northern Australian Fishes: A New Species of Seamoth (Genus Pegasus).

Fishes are one of the most intensively studied marine taxonomic groups yet cryptic species are still being discovered. An integrated taxonomic approach is used herein to delineate and describe a new cryptic seamoth (genus Pegasus) from what was previously a wide-ranging species. Preliminary mitochondrial DNA barcoding indicated possible speciation in Pegasus volitans specimens collected in surveys of the Torres Strait and Great Barrier Reef off Queensland in Australia. Morphological and meristic investigations found key differences in a number of characters between P. volitans and the new species, P. tetrabelos. Further mt DNA barcoding of both the COI and the slower mutating 16S genes of additional specimens provided strong support for two separate species. Pegasus tetrabelos and P. volitans are sympatric in northern Australia and were frequently caught together in trawls at the same depths
