Abstract

ABSTRACT: Examination of spiral intestines from Himantura tutul Borsa, Durand, Shen, Arlyza, Solihin, and Berrebi, 2013 (=Himantura uarnak 3 sensu Naylor et al. [2012]), collected from Malaysian Borneo revealed the presence of a new species of tapeworm belonging to the genus Stillabothrium (Rhinebothriidea: Escherbothriidae). Stillabothrium borneoense n. sp. Herzog, Meininger, and Reyda is assigned to the genus based on its possession of a scolex with 4 bothridia divided into a distinct anterior region with facial loculi that are oriented horizontally and a distinct posterior region with facial loculi that are oriented vertically. The new species is distinguished from its congeners by features of the scolex and proglottids, including a vagina that recurves well anterior to the cirrus sac, as well as a unique locular arrangement not previously reported for members of this genus: 4 horizontally oriented loculi in the anterior region of the bothridia and 7 vertically oriented loculi in the posterior region of the bothridia. Stillabothrium borneoense n. sp. expands both known morphological variation and known host associations within the genus.

婆罗洲黄貂鱼缢蛏属绦虫一新种(缢蛏总科:缢蛏科)

摘要:对2013年在马来西亚婆罗洲采集的Himantura tutul Borsa、Durand、Shen、Arlyza、Solihin和Berrebi (=Himantura warnak 3 sensu Naylor et al.[2012])的螺旋肠进行检测，发现一种新的绦虫属Stillabothrium (rhinbothri总科:Escherbothriidae)。Herzog, Meininger和Reyda将其归属于该属，基于其拥有一个具有4个头节的头节，头节分为具有水平方向的面室的明显前部区域和具有垂直方向的面室的明显后部区域。这个新物种与它的同系物的区别在于它的头节和原门动物的特征，包括一个在卷云囊前面弯曲的阴道，以及一个以前在这个属的成员中没有报道过的独特的房室安排:在两根前区有4个水平方向的房室，在两根后区有7个垂直方向的房室。冰片蓟马(Stillabothrium borneense n. sp.)扩展了已知的形态变异和已知的属内宿主关联。

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
