The systematics and molecular phylogeny of Ptereleotrines (Teleostei:Gobioidei) / 鰭鰕虎類群之形態分類與分子演化研究

碩士 / 國立臺灣海洋大學 / 海洋生物研究所 / 98 / Dartfishes (Ptereleotrinae) belong to the member of Gobiidae (Teleostei:Perciformes). This research has revised the systematic status of so-called “Ptereleotrines” in Taiwan. There are four genera and 7 species including a newly recorded genus Oxymetopon as Oxymetopon formosum in Taiwan. Current research employed morphological (including osteological features) and molecular (including partial sequences of mtDNA ND5 gene with 964 bp; nuclear ryanodine receptor 3 with 857 bp and SH3 and PX domain containing 3 genes with 720 bp) for reconstructing phylogenetic relationship for locating Ptereleotrinae among other gobioid fishes.
The results of osteological survey reveal the great differentiation not only for the shape of coracoid in pectoral girdle in between Amblygobius and members of Ptereleotrinae group (including these genera as Aioliops, Nemateleotris and Ptereleotris), but also the shape of posttemporal of arculating in between them.
The overall molecular phylogenetic approach inferred from nuclear genes by BI method reveal that the group of Ptereleotrines can be considered as one derived clade within Gobiinae with high bootstrap support (61-88%). The data strongly suggests that the monophyletic Ptereleotrines could be reconsidered as “tribe Ptereleotrini” within Gobiinae.
