摘要

摘要从多巴哥岛（特立尼达和多巴哥）和Carrie Bow Cay岛（伯利兹）的海底沉积物中描述了一个新的Thaumastoderma属物种（Gastrotricha:Macrodasyida:Thaumastodermatidae）。Thaumastoderma ponticulus sp.nov.与Th.ramuliferum和Th.cantacuzeni相似，因为存在四对背卷管和一对复合的匙形触须。主要的区别特征是存在一个肉质桥，连接头部的前部和后部匙形触手。附加特征包括存在两排前部粘合管、七对腹外侧粘合管和五对后部粘合管。

Description of a new species of Thaumastoderma (Gastrotricha: Macrodasyida: Thaumastodermatidae) from Belize and Tobago

Abstract A new species of Thaumastoderma (Gastrotricha: Macrodasyida: Thaumastodermatidae) is described from sublittoral sediments on the islands of Tobago (Trinidad and Tobago) and Carrie Bow Cay (Belize). Thaumastoderma ponticulus sp. nov. is similar to Th. ramuliferum and Th. cantacuzeni based on the presence of four pairs of dorsal cirrata tubes and a compound pair of spatulate tentacles. The main distinguishing characteristic is the presence of a fleshy bridge that interconnects the anterior and posterior spatulate tentacles on the head. Additional characters include the presence of two rows of anterior adhesive tubes, seven pairs of ventrolateral adhesive tubes, and five pairs of posterior adhesive tubes.
