Abstract

A new species, Hemipera cribbi sp. nov., is described. This trematode was found in three intertidal fish species: Scartichthys viridis (Valenciennes) (Blenniidae), Gobiesox marmoratus Jenyns (Gobiesocidae) and Myxodes viridis Valenciennes (Clinidae) from the central and southern coast of Chile. Of 233 individuals of S. viridis from the central coast examined, 19 were infected. From the southern coast, nine individuals of S. viridis (one infected), five individuals of G. marmoratus (four infected), and 16 individuals of M. viridis (one fish infected) were examined. Hemipera cribbi sp. nov. is distinguished from the five other congeneric species mainly in the body size, being the smallest and narrowest species in the genus, reaching five times longer than wide. This is the first species of the genus described for the South Pacific Ocean off South America. ITS2 rDNA sequences of Hemipera cribbi sp. nov. from each host and locality were identified.

摘要

描述了一个新物种，即克里布半孔吸虫（Hemipera cribbi sp. nov.）。这种吸虫发现于三种潮间带鱼类：来自智利中南部海岸的绿拟鲉（Scartichthys viridis (Valenciennes)，鳚科）、斑纹喉盘鱼（Gobiesox marmoratus Jenyns，喉盘鱼科）和绿黏杜父鱼（Myxodes viridis Valenciennes，杜父鱼科）。在检查的来自中部海岸的233条绿拟鲉个体中，有19条被感染。在南部海岸，检查了9条绿拟鲉个体（1条被感染）、5条斑纹喉盘鱼个体（4条被感染）和16条绿黏杜父鱼个体（1条被感染）。克里布半孔吸虫（Hemipera cribbi sp. nov.）与其他五个同属物种的主要区别在于体型，它是该属中最小且最窄的物种，体长达到体宽的五倍。这是在南美洲以南的南太平洋描述的该属的第一个物种。已鉴定出来自每个宿主和地点的克里布半孔吸虫（Hemipera cribbi sp. nov.）的ITS2 rDNA序列。
