TL;DR: Pandaka is confirmed as the sister genus to Brachygobius, these genera forming a crown group, with Redigobius and Pseudogobius forming successive sister groups, in agreement with morphological hypotheses of phylogeny.
Abstract: Horizontal starch gel electrophoresis was employed to analyse genetic variation, at 19 isozyme loci, in six putatively related species of gobies (Brachygobius aggregatus, B. doriae, Pandaka lidwilli, Pseudogobius olorum, Pseudogobius sp. and Redigobius sp.), using seven other gobiine species as an outgroup. Allozyme data was analysed both cladistically and phenetically, all treatments confirming the monophyly of the group. Pandaka is confirmed as the sister genus to Brachygobius, these genera forming a crown group, with Redigobius and Pseudogobius forming successive sister groups. This scenario is in agreement with morphological hypotheses of phylogeny. However, this lineage appears to be relatively unrelated to other groups within the Gobiinae

TL;DR: The gobiid fish genus Mugilogobius and 13 closely related genera form a monophyletic group within the sub-family Gobionellinae of the family Gobiidae as mentioned in this paper.
Abstract: The gobiid fish genus Mugilogobius and 13 closely-related genera form a monophyletic group within the sub-family Gobionellinae of the family Gobiidae. Included with Mugilogobius in this group are the genera Brachygobius, Caecogobius, Calamiana, Chlamydogobius, Eugnathogobius, Gobiopterus, Hemigobius, Mistichthys, Pandaka, Pseudogobius, Redigobius, Stigmatogobius and Tamanka. These 14 genera are discussed and compared. The entire group consists of about 105 species, which have been greatly confused in the literature. Of these species, 12 are here described as new. The genera Calamiana, Chlamydogobius, Eugnathogobius, Hemigobius, Mugilogobius and Tamanka are revised, and full descriptions of the species included in each genus are provided. The genera Brachygobius, Caecogobius, Gobiopterus, Mistichthys, Pandaka, Pseudogobius, Redigobius and Stigmatogobius are diagnosed, nominal species are listed and an indication of the probable number of valid species given.Mugilogobius includes 25 species, of which eight are described as new. The genus is defined by a combination of characters. Most species of Mugilogobius occur in estuarine to fresh waters, with some species widespread in the Indo-west Pacific and others restricted to a single waterbody. There is a species-complex in the tectonic lakes of Sulawesi, characterised by vertebral pattern and several character reversals.Cladistic analyses of the Mugilogobius-group indicate that Chlamydogobius (restricted to Australia) is the sister-group to Mugilogobius. The monophyletic genus Tamanka is sister to the Mugilogobius-Chlamydogobius group. Hemigobius is the sister group to Pseudogobius. Brachygobius and Pandaka form a closely related group. Stigmatogobius is derived compared to Redigobius, a genus with the most plesiomorphic characters of the whole Mugilogobius-group. Eugnathogobius appears to be paraphyletic.The Gobionellinae thus includes the Mugilogobius-group and a second monophyletic group in which are placed the genera Awaous, Evorthodus, Ctenogobius, Gnatholepis, Gobionellus, Oligolepis, Oxyurichthys and Stenogobius. The relationship of Redigobius and Rhinogobius to these groups is somewhat equivocal. All these gobionellines share certain characters, particularly those of the dorsal pterygiophore formula, epural number, vertebral number, headpore arrangement and a tendency to occur in freshwater to estuarine habitats. .........
