碩士 === 國立臺灣海洋大學 === 海洋生物研究所 === 102 === The fishes of sandperches ( Family Pinguipedidae ) are known as the belong to class Actinopterygii, subclass Neopterygii order Perciformes, suborder Trachinoidei. They live mainly on sandy or sand-rubble areas； and they are usually carnivorous, feeding principally on benthic crustaceans, especially crabs and shrimps, occasionally on small fishes. The sandperch Family Pinguipedidae comprises 7 genera and 83 valid species. A total of 25 valid species of the Parapercis and in family Pinguipedidae has been recorded in Taiwanese waters. This research focus on all available Pinguipedidae species (comprises 25 species ) collected from Taiwan. There are 1 undescribed new species, 1 new species： Parapercis dongsharensis and 2 newly recorded species：Parapercis okamurai, P. pacifica. The molecular phylogenetic approach has been conducted by 3 fragments of partial sequences of mtDNA ND5 ( 903bp ), COI ( 612bp ), and 12SrRNA ( 985bp ) genes. The results of 3 genetic marked phylogenetic analysis revealed 6 groups on Parapercis species. They are (1) Parapercis sexfasciata, P. lutevittata；(2) P. tetracantha, P. kamoharai, P. pacifica, P. tetracantha, P. xanthozona；(3) P. schauinslandi, P. snyderi；(4) P. okamurai, P. striolata；(5) P. kentingensis, P. shaoi；(6) P. macrophthalma, P. multifasciata, P. decemfasciata. The overall major topology of moleculor phylogenetic tree can be correlated to the different coloration patterns, cephalic sensory pores and proportion of eyes diameter of the sandperches.
