“…Since the 1990s, taxonomic studies have increasingly used DNA markers as accurate tools for species identification. Integrating molecular information and classical morphological approaches has been suggested as a logical framework which improves species descriptions and delineation, while also frequently flags the presence of cryptic species (Borsa, ; Dayrat, ; Zemlak et al , ; Schlick‐Steiner et al , ; Victor, ; Baldwin & Weigt, ; Fujita et al , ; Puillandre et al , ; Puckridge et al , ; Baldwin & Johnson, ; Conway et al , ; Kekkonen & Hebert, ; Lavoué et al , ; Thomas et al , ).…”

To deal with the difficulties of species differentiation and delimitation among the commercially important sardines from the genus Sardinella, an integrative approach was adopted, incorporating traditional taxonomy with four DNA markers (coI, cytb, 16s and nuclear rag2). Combining these methodologies has enabled a thorough re-description of three of the most common species of Sardinella of the Indo-west Pacific Ocean: white sardinella Sardinella albella, fringescale sardinella Sardinella fimbriata and the goldstripe sardinella Sardinella gibbosa, as well as a description of a new species, Gon's sardinella Sardinella goni, from the island of Boracay, Philippines. In addition, extensive widespread sampling of S. gibbosa reveals a significant genetic separation between the populations from the western Indian Ocean and the west Pacific Ocean, despite no supporting morphological differentiation. An updated morphological key of the species of Sardinella of the Indo-west Pacific Ocean is also provided in order to minimize future misidentifications within these economically important taxa. Finally, the genetic and morphological variabilities within and between the investigated species are used to discuss their biogeographical distribution and possible processes of speciation.

Flexorincus, new genus and species, is described from 15 specimens (14.0–27.2 mm SL) collected from shallow (0–9 meters) intertidal and sub-tidal waters of the Rangitāhua Kermadec Islands, New Zealand. The new taxon is distinguished from all other members of the Gobiesocidae by a combination of characters, including a heterodont dentition comprising both conical and distinct incisiviform teeth that are laterally compressed with a strongly recurved cusp, an oval-shaped opening between premaxillae, a double adhesive disc with a well-developed articulation between basipterygia and ventral postcleithra, and many reductions in the cephalic lateral line canal system. The new taxon is tentatively placed within the subfamily Diplocrepinae but shares a number of characteristics of the oral jaws and the adhesive disc skeleton with certain members of the Aspasminae and Diademichthyinae.

“…There are numerous examples of integrative taxonomic approaches that have led to the description of new species in, for example, gobiids (Winterbottom et al, 2014), gobiesocids (e.g. Conway, Baldwin & White, 2014), or tripterygiids (e.g. Victor, 2013).…”

The hidden half: ecology and evolution of cryptobenthic fishes on coral reefs

et al. 2018

Teleost fishes are the most diverse group of vertebrates on Earth. On tropical coral reefs, their species richness exceeds 6000 species; one tenth of total vertebrate biodiversity. A large proportion of this diversity is composed of cryptobenthic reef fishes (CRFs): bottom-dwelling, morphologically or behaviourally cryptic species typically less than 50 mm in length. Yet, despite their diversity and abundance, these fishes are both poorly defined and understood. Herein we provide a new quantitative definition and synthesise current knowledge on the diversity, distribution and life history of CRFs. First, we use size distributions within families to define 17 core CRF families as characterised by the high prevalence (>10%) of small-bodied species (<50 mm). This stands in strong contrast to 42 families of large reef fishes, in which virtually no small-bodied species have evolved. We posit that small body size has allowed CRFs to diversify at extremely high rates, primarily by allowing for fine partitioning of microhabitats and facilitation of allopatric reproductive isolation; yet, we are far from understanding and documenting the biodiversity of CRFs. Using rates of description since 1758, we predict that approximately 30 new species of cryptobenthic species will be described per year until 2050 (approximately twice the annual rate compared to large fishes). Furthermore, we predict that by the year 2031, more than half of the described coral reef fish biodiversity will consist of CRFs. These fishes are the 'hidden half' of vertebrate biodiversity on coral reefs. Notably, global geographic coverage and spatial resolution of quantitative data on CRF communities is uniformly poor, which further emphasises the remarkable reservoir of biodiversity that is yet to be discovered. Although small body size may have enabled extensive diversification within CRF families, small size also comes with a suite of ecological challenges that affect fishes' capacities to feed, survive and reproduce; we identify a range of life-history adaptations that have enabled CRFs to overcome these limitations. In turn, these adaptations bestow a unique socio-ecological role on CRFs, which includes a key role in coral reef trophodynamics by cycling trophic energy provided by microscopic prey to larger consumers. Although small in body size, the ecology and evolutionary history of CRFs may make them a critical component of coral-reef food webs; yet our review also shows that these fishes are highly susceptible to a variety of anthropogenic disturbances. Understanding the consequences of these changes for CRFs and coral reef ecosystems will require us to shed more light on this frequently overlooked but highly diverse and abundant guild of coral reef fishes.
