AI Article Synopsis
- - A new species of polyclad flatworm, named Pericelis flavomarginata sp. nov., has been identified along the Pacific coast of Japan, found in both intertidal and subtidal zones.
- - This species has a distinctive appearance with a lemon-yellow fringe on its body and a brown midline, as well as notable features like tapering tentacle tips and a shared reproductive opening.
- - Molecular analysis shows that Pericelis species group into two clades based on dorsal color patterns, and the feeding behavior of P. flavomarginata sp. nov. was observed preying on the polychaete Iphione muricata.
Article Abstract
We describe a new species of polyclad flatworm, Pericelis flavomarginata sp. nov., from the intertidal and subtidal zones along localities on the Pacific coast of Japan. Pericelis flavomarginata sp. nov. is characterized by i) the dorsal surface of the body fringed by a lemon-yellow line except for the tip of tentacles, with a narrow brown midline running from the anterior edge of the body to the posterior end of the pharynx, ii) the pair of marginal tentacles with the tips extending and tapering, and iii) the presence of a common gonopore. Our molecular phylogenetic analysis revealed that selected Pericelis species were divided into two clades, each of which may be agreed with a characteristic dorsal color pattern. Additionally, we report an observation on the feeding behavior of P. flavomarginata sp. nov. on the polychaete Iphione muricata (Savigny in Lamarck, 1818).

This study presents a combination of radiography and ultrasonography to observe the reproductive cycle of 24 captive female yellow-margined box turtles in Taiwan. Radiography was mainly used to monitor clutch size, whereas ultrasonography was applied to detect changes in the follicles throughout the year. The observation of the 24 female turtles was performed from April 2007 to June 2008.
