چکیده
Abstract We establish a new genus of planocerid polyclad, Heteroplanocera gen. nov., based on species, H. katoi sp. collected at depth 245 m off the coast Izu Peninsula, West Pacific, Japan. nov. is distinguished from other genera by following characteristics: (i) pair nuchal tentacles, (ii) muscular bulb, (iii) spermiducal bulbs (instead seminal vesicle), (iv) free prostatic vesicle, (v) accessory organs with teeth, (vi) Lang's and (vii) lack bursa copulatrix. provide partial sequence cytochrome c oxidase subunit I (COI) gene (712 bp) as DNA barcode species. Furthermore, we estimate phylogenetic position among Planoceridae sequences COI 16S, 18S, 28S ribosomal DNA. Based our findings, discuss evolution function vaginal cuticularized structure flatworms.

Trophoniella hephaistos sp. n. was collected from a tank irrigated with seawater pumped directly from Nabeta Bay, Japan. This species is discriminated from other Trophoniella by having dorsal tubercles, a tongue-shaped branchial plate, a tunic covered with large sediment grains dorsally and ventrally, having eyes, and anchylosed neurohooks starting from chaetigers 17-20. This is the first recor...

Lapsamita maddisoni gen. et sp. nov. is described from Bahia, Brazil. The presence of palpal claws in females, long ventral spines on front tibiae and metatarsi and long retrolateral tibial apophyses in male palps suggested that the species was closely related to or even nested within Soesiladeepakius Makhan, 2007. To evaluate its phylogenetic position, a cladistic analysis was carried out usin...
متن کاملState of knowledge of the Acotylea (Polycladida, Platyhelminthes) from the Mediterranean coasts of Spain: new records and new species.
Along the Mediterranean coast of the Iberian Peninsula, great species diversity is thought to exist, but our knowledge of Iberian polyclads is, in fact, very limited. This study contributes to the Polycladida (Platyhelminthes) of the Iberian Peninsula, in particular those of the Mediterranean coast. Nine species, mainly new species or new records, are described. Imogine stellae sp. nov. from Ma...
