| contents | Integrative Phylogenetic and Morphological Analyses Reveal Two New Species of Porcellanid Crabs and Resurrect Stimpson, 1858 (Decapoda: Porcellanidae). Loke, Hai Xin Heung, Bonnie Yuen Wai Li, Yi-Xuan Lin, Yi-Tao Hosie, Andrew M Wang, Zhi McNamara, Marissa Qiu, Jian-Wen Members of the genus White, 1851 (Porcellanidae) are common commensals of sea pens in tropical and subtropical coastal waters. Despite having only three described species ( White, 1851 from Cape Capricorn, Australia; Stimpson, 1858 from Hong Kong; and Sankarankutty, 1963 from the Gulf of Mannar, Indian Ocean), the taxonomy of this genus has been widely debated. was previously considered a junior synonym of , but this synonymization has been the subject of disagreement. In this study, we conducted integrative phylogenetic and morphological analyses of specimens tentatively identified as , collected from Hong Kong, Taiwan, mainland China, Thailand, Singapore and Australia. Our Maximum Likelihood and Bayesian Inference phylogenetic analyses of mitochondrial and sequences revealed four distinct lineages: one corresponding to from Asia, one to and two representing new species ( n. sp. and n. sp.) from Australia. Morphologically, species can be distinguished by the colour markings on the chelipeds and carapace, the shape of the trilobate rostrum, the presence or absence of a meral lobe on the cheliped, the relative size of the unguicles on the ambulatory leg dactylus, and the presence or absence of a spinule on the lateral margin of the pterygostomian flap. We provide a morphological key to the species of . Our study demonstrates the value of an integrative approach in distinguishing cryptic invertebrate species that are considered to exhibit wide geographic distribution patterns. |
