Genetic variation was examined in two complex cases of Indo-Pacific pygmy angelfishes (genus Centropyge; Pomacanthidae). The lemonpeel pygmy angelfish C. flavissima (Cuvier and Valenciennes) has a geographically disjunct Indian vs. Pacific distribution and the individuals from these two regions differ by their colour patterns. Previous research on C. flavissima has shown mitochondrial introgression from two related species, C. eibli in the eastern Indian Ocean and C. vrolikii in the Pacific… 
Angelfishes, Paper Tigers, and the Devilish Taxonomy of the Centropyge flavissima Complex.
It is concluded that the Black Tiger Centropyge is not a valid species but rather an intermediate between sympatric color morphs that correspond to the putative species C. flavissima, a taxonomic oddity restricted to shoals and atolls off the coast of northwestern Australia.
Response to Delrieu-Trottin et al.: Hybrids, Color Variants and the Consistently Devilish Taxonomy of Pygmy Angelfishes.
The Indian Ocean C. flavissima was genetically distinctive from the Pacific Ocean form, but genetically indistinguishable from sympatric C. vrolikii across the entire range of “C. cocosensis”.
Diagnostic description and geographic distribution of four new cryptic species of the blue-spotted maskray species complex (Myliobatoidei: Dasyatidae; Neotrygon spp.) based on DNA sequences
The present taxonomic revision will provide information relevant to the sound management and conservation of cryptic species of the blue-spotted maskray in the Coral Triangle region.
Do ecological traits of low abundance and niche overlap promote hybridisation among coral-reef angelfishes?
Empirical evidence is provided that hybridisation in reef fishes conforms to terrestrial-based hypothesis, and thus advances the understanding of the processes underlying Hybridisation in coral-reef systems.
One Species Hypothesis to Rule Them All: Consistency Is Essential to Delimitate Species.
The newly-desribed Centropyge cocosensis has long been considered a variant of the lemonpeel pygmy angelfish C. flavissima because of their overall similarity in color patterns. DiBattista and
Causes and possible consequences of hybridisation in angelfishes at Christmas Island
This thesis aims to provide a history of natural hybridisation in angelfishes of the world and some of the mechanisms that led to this process are described.

Twisted sister species of pygmy angelfishes: discordance between taxonomy, coloration, and phylogenetics
The mtDNA phylogeny reveals a period of isolation typical of congeneric species, whereas the within-lineage mtDNA ΦST values and the nuclear DNA data reveal recent or ongoing gene flow between species, which concludes that an ancient divergence of C. flavissima was swamped by introgression and hybridization in two of the three regions.
Shallow mtDNA coalescence in Atlantic pygmy angelfishes (genus Centropyge) indicates a recent invasion from the Indian Ocean.
The mtDNA genealogy indicates a colonization pathway from the Indian Ocean directly to the West Atlantic, followed by at least two waves of dispersal to the Mid-Atlantic Ridge.
Mitochondrial and nuclear DNA analyses revealed signifi cant differences between the species (6.07% sequence divergence on mtDNA and a 25 base pair indel on nDNA), reinforcing their distinct taxonomic status.
Genetic connectivity among color morphs and Pacific archipelagos for the flame angelfish, Centropyge loriculus
While there is a strong geographic component to the distribution of color morphs in C. loriculus, there is no evidence for corresponding genetic partitioning, and genetic studies in conjunction with larval distribution data indicate that Centropyge species are highly dispersive.
Patterns of genetic isolation in a widely distributed pelagic fish, the narrow-barred Spanish mackerel (Scomberomorus commerson)
It is hypothesized that in S. commerson and possibly other Scomberomorus species, philopatric migration may play a role in maintaining the geographic isolation of populations by annihilating the potential consequences of passive dispersal.
Macropharyngodon pakoko, a new species of wrasse (Teleostei: Labridae) endemic to the Marquesas Islands, French Polynesia.
A new species of wrasse is described from the Marquesas Islands, bringing the total number of species of the genus Macropharyngodon to 12 and differs genetically and in several coloration characters.
