Stibarobdella macrothela (Annelida, Hirudinida, Piscicolidae) from Elasmobranchs in Japanese Waters, with New Host Records
The piscicolid leech Stibarobdella macrothela (Schmarda, 1861) was collected from three elasmobranchs (ornate eagle ray Aetoinylaens vespertilio, banded houndshark Triakis scylliunn, and tiger shark Galeocerdo cuvier) in Japanese waters. The first two species (A. vespertilio and T. scyllium) are new hosts, and G. cuvier is newly recorded as a host in Japan. The external morphology of the smallest leech specimen (total length 16 mm) is figured.
