Relaxed molecular clock divergence time estimation indicates a Pliocene origin for the new species, and the current distribution of the new species and its sister species Eviota sebreei supports a scenario of vicariance across the Indo-Pacific Barrier, followed by subsequent range expansion and overlap in the Coral Triangle. These results are consistent with the 'centre of overlap' hypothesis, which states that the increased diversity in the Coral Triangle is due in part to the overlapping ranges of Indian Ocean and Pacific Ocean faunas. These findings are discussed in the context of other geminate pairs of coral reef fishes separated by the Indo-Pacific Barrier.

PEZOLD 2 1 Museum and Art Gallery Northern Territory, GPO Box 4646, Darwin, NT 0 801, Australia; Museum of Tropical Queensland, Townsville, Queensland 4810, Australia; School of Marine and Tropical Biology, James Cook University, Townsville, Queensland 4811, Australia. E-mail: helen.larson@nt.gov.au 2 College of Science & Engineering, Texas A&M University - Corpus Christi, Corpus Christi, TX; 78412 - 5806, USA. E-mail: frank.pezold@tamucc.edu In 2015, Pezold and Larson published a revision of the gobiid genus Oxyurichthys, and made an error in their use of the name O. uronema (Weber) for one of the species. The reasons for this would make a fine example of one of Evenhuis' taxonomic impediments to nirvana (2007). Pezold and Larson first considered collaborating on this work in 1983, but this did not happen until nearly a decade later. Intensive work began in 1996; by then Larson had examined syntypes of both species in 1988 and determined that Gobius uronema Weber, 1909, was the same species as Gobius longicauda Steindachner, 1893. We assumed that Steindachner's Gobius longicauda was a primary homonym of G. longicaudus Jenkins and Evermann, 1889 (a synonym of Ctenogobius sagittula (Günther)), based on our interpretation of the 1985 version of the International Code of Nomenclature. However, a statement to this effect was absent from the final manuscript, having been edited out sometime between 2008 and 2011. It must be confessed that when the latest version of the Code appeared in 1999, we did not notice that changes to Article 34 (Mandatory changes in spelling consequent upon changes in rank or combination) were relevant to the name of this species. Article 34.2 states that: "The ending of a Latin or latinized adjectival or participial species-group name must agree in gender with the generic name [...]

All current members of the Alliance are part of the Texas A&M University System. Many high impact practices (HIP) have been emphasized in the Alliance’s 30 years of programming with Diversity/Global Learning as a focus in the last 14 years. Diversity/Global Learning has been supported in two formats on the Alliance campuses, through traditional study abroad programming and a College of Engineering initiative. Data presented were derived from a number of sources, project evaluation information regarding student perspectives and outcomes, survey research conducted by an independent party, and institutional data and online platforms accessed to assess student outcomes. Triangulation was completed between data sets. Results indicate both forms of programming were efficacious for underrepresented and first-generation students. Outcomes reported were substantial incr...

In total, 206 specimens were collected between June 2010 and August of 2012 on three different trips. The AMOVA results from both types of loci reveal that >95% of variation is contained within populations. Pairwise comparisons reveal non-significant differences between three different regions for the mitochondrial analysis but a significant difference between the west and central regions for the microsatellites. The findings in this study concur with results from previous studies, indicating low or no population structure among populations of amphidromous sicydiine goby species on different islands within an archipelago. This study can provide suggestions for management and conservation of fragile aquatic species.

My observations and comments are largely focused on their relevance to the recognition of a family Gobionellidae including the previously recognized subfamily Gobionellinae (Pezold, 1993; Larson, 2001; Thacker, 2003) i.e. gobionellines sensu stricto, and the amblyopines, oxudercines and sicydiines (sensu Pezold, 1993). Additional observations are given on the Gobiidae clade (sensu Thacker 2009), and the sister group relationship proposed between the Butidae and the two goby clades recovered by Thacker (2009). The clade-based classification proposed by Thacker (2009) names putative monophyletic groups, but no synapomorphy is given for the family Gobionellidae, or for any of the families recognized therein. Origins of the Gobionellinae Bleeker (1874) was the first person to use a derivative of Gobionellus for a grouping of t...
