采用形态学、形态计量学和分子生物学的方法,对牙买加凤梨科植物中的薄腹凤梨进行了描述。我们增加了Leptopharynx共状态的重要数据,并简要地描述和回顾了Leptopharynx属,包括四个新的组合。根据以下主要特征,并假设大多数或全部具有产生大口的能力,可以区分出9种:沿着右侧纤毛排有明显的脊;特殊特征,如身体和口篮上的刺或翅膀;双动体存在与不存在于躯体动体3;6型的动体数为2个,凤梨花型的动体数≥5个;动蛋白9的开始和结构在口膜下面或远在口膜下面,有或没有二动质体;后脑复合体有vs无;口前运动是连续的还是不连续的。L. bromelicola和L. costatus的18S rDNA序列差异为1.7%,表明Leptopharynx在nasshorea中形成了一个不同的分支。凤梨瘦鼻虫可能与euglenivora瘦鼻虫有密切的亲缘关系,但后者缺乏前者所特有的篮状鼻。瘦咽形成薄壁的、不吸收动体的静息囊,维持大部分的营养细胞器。
Using morphological, morphometrical, and molecular methods, we describe Leptopharynx bromelicola n. sp. from tank bromeliads of Jamaica. We add significant data to Leptopharynx costatus and briefly characterize and review the genus Leptopharynx , including four new combinations. Nine species can be distinguished when applying the following main features and assuming that most or all have the ability to produce macrostomes (MAs): distinct ridges along the right side ciliary rows; special features like spines or wings on the body and of the oral basket; dikinetids present vs. absent from somatic kinety 3; number of kinetids in kinety 6 as two for the costatus pattern and ≥ five for the bromelicola pattern; beginning and structure of kinety 9 as either underneath or far underneath the adoral membranelles and with or without dikinetids; postoral complex present vs. absent; and preoral kinety 4 continuous vs. discontinuous. The 18S rDNA sequences of L. bromelicola and L. costatus differ by 1.7% and show that Leptopharynx forms a distinct clade within the Nassophorea. Leptopharynx bromelicola is possibly closely related to Leptopharynx euglenivora , which, however, lacks the basket nose so typical of the former. Leptopharynx forms thin-walled, non-kinetosome-resorbing resting cysts maintaining most of the trophic organelles.
