- Abstract
<italic>Kelloggella</italic> is a widely distributed but poorly studied genus of goby (family Gobiidae) that occurs in tide pool and reef flat habitats across the tropical Indo-Pacific region. The phylogenetic position of this genus has never been formally investigated, and its osteology has not been described in detail. The discovery of a new species of <italic>Kelloggella</italic> from the island of Nuie, coupled with the recent availability of fresh specimens, tissues and photographs of <italic>Kelloggella</italic> spp. from Hawaii and Easter Island, has led to the current study. Here, we describe the new species as <bold><italic>Kelloggella avaiki</italic> sp. nov.</bold> and investigate the phylogenetic position of <italic>Kelloggella</italic> within Gobiidae. Molecular phylogenetic data from nuclear and mitochondrial genes suggest a close relationship between <italic>Kelloggella</italic> and <italic>Gobiodon</italic>, <italic>Eviota</italic> and <italic>Bryaninops</italic>, and possibly <italic>Kraemeria</italic>. A comparative osteological investigation identified few potentially informative characters, including a reduced ventral branch of the posttemporal, epioccipitals meeting along the dorsal midline posterior to the supraoccipital, hypurals 1–2 fused to hypurals 3–4 and the urostyle and the presence of tricuspid teeth. However, these characters occur elsewhere across gobies, and at best only offer weak support for the relationships hypothesized by the molecular tree. Lastly, we provide colour photographs of five species of <italic>Kelloggella</italic> and discuss some of the challenges in delimiting species.
