“…These characters relate to the anteriorly elongate and posteriorly broadened parasphenoid; the toothed premaxillary and dentary; the presence of small, curved, conical oral teeth; the symplectic foramen; the opercle without spines; the bifurcated posttemporal; the presence of four radials; the presence of vertebral centra that are longer than high; the caudal skeleton with two large hypural plates (Hy), comprising Hy1+2 and Hy3+4, and a small hypural plate 5; and the presence of branched fin rays (see [ 4 – 6 , 20 , 29 , 48 , 51 , 52 , 54 – 56 ]). The shape of the frontal bones is also excluded, as it has been shown to differ between congeneric species [ 12 ]. A non-toothed vomer, although occurring in many groups of gobioids, is not excluded because one species of the Eleotridae, Eleotris vomerodentata Maugé, 1984, endemic to Madagascar, was described as new because of plenty teeth on the vomer [ 57 ].…”

Freshwater gobies 30 million years ago: New insights into character evolution and phylogenetic relationships of †Pirskeniidae (Gobioidei, Teleostei)

The modern Gobioidei (Teleostei) comprise eight families, but the extinct †Pirskeniidae from the lower Oligocene of the Czech Republic indicate that further families may have existed in the past. However, the validity of the †Pirskeniidae has been questioned and its single genus †Pirskenius has been assigned to the extant family Eleotridae in previous works. The objective of this study is to clarify the status of the †Pirskeniidae. Whether or not the †Pirskeniidae should be synonymised with the Eleotridae is also interesting from a biogeographical point of view as Eleotridae is not present in Europe or the Mediterranean Sea today. We present new specimens and reexamine the material on which the two known species of †Pirskenius are based (†P. diatomaceus Obrhelová , 1961; †P. radoni Přikryl, 2014). To provide a context for phylogenetically informative characters related to the palatine and the branchiostegal rays, three early-branching gobioids (Rhyacichthys, Protogobius, Perccottus), an eleotrid (Eleotris) and a gobiid (Gobius) were subjected to micro-CT analysis. The new data justify revalidation of the family †Pirskeniidae, and a revised diagnosis is presented for both †Pirskenius and †Pirskeniidae. Moreover, we provide for the first time an attempt to relate a fossil gobioid to extant taxa based on phylogenetic analysis. The results indicate a sister-group relationship of †Pirskeniidae to the Thalasseleotrididae + Gobiidae + Oxudercidae clade. Considering the fossil record, the arrival of gobioids in freshwater habitats in the early Oligocene apparently had generated new lineages that finally were not successful and became extinct shortly after they had diverged. There is currently no evidence that the Eleotridae was present in the European ichthyofauna in the past.

“…To test which speciation models and clocks best fit our data, they were compared using the Akaike's information criterion through MCMC (AICM; Raftery et al, 2007) with Tracer v1.6 (Rambaut et al, 2014). For sand gobies, otoliths are the most common fossil remains, while skeletal remains are scarce (Bratishko et al, 2015; Gierl & Reichenbacher, 2017; Schwarzhans, 2014; Schwarzhans et al, 2017). For this reason, some authors performed otolith‐based dating using the ages of P. bunyatovi and K. suavis as calibration points.…”

The Adriatic Sea and Adriatic Sea drainage system (or Adriatic region) is characterized by high levels of species richness. This especially applies to endemic fishes, as exemplified by the sand gobies. However, the diversity of this group is probably still underestimated. Several keys for gobiid identification, notably of the Adriatic region, have been proposed on the basis of morphological characters, but difficulties persist in species identification. Molecular phylogenies support the monophyly of the sand gobies, but relationships between genera and species remain poorly resolved. In this work, the diversity and evolutionary history of the Adriatic sand gobies (Pomatoschistus and Knipowitschia) were investigated by applying phylogenetic reconstructions, species delimitation tests, and molecular dating based on mitochondrial cytochrome b and nuclear rhodopsin 1 genes. The concatenation of both genes allowed, for the first time, the creation of a highly resolved phylogeny at the interspecific level. The generic diversity within the sand gobies is probably considerably higher than formerly assumed. Our results highlight cryptic diversity and suggest that new species remain to be described within Knipowitschia and Pomatoschistus. Most of all, our results emphasized the urgent need of a taxonomic revision of the sand gobies. Several past events were at the origin of sand goby diversification in the Adriatic region. It seems that glacial periods promoted the intraspecific diversification of the endemic species, whereas interglacial periods promoted the (re)colonization of the Adriatic Sea by more widespread species.
