A new quadrannulate species of Orobdella (Hirudinida, Arhynchobdellida, Orobdellidae) from central Honshu, Japan

Abstract. A new quadrannulate species of Orobdella, Orobdella masaakikuroiwai sp. n., from the mountainous region of central Honshu, Japan is described. This is only the second small species known within this genus, with a body length of less than 4 cm for mature individuals. Phylogenetic analyses u...

Sumario:Abstract. A new quadrannulate species of Orobdella, Orobdella masaakikuroiwai sp. n., from the mountainous region of central Honshu, Japan is described. This is only the second small species known within this genus, with a body length of less than 4 cm for mature individuals. Phylogenetic analyses using nuclear 18S rDNA and histone H3 as well as mitochondrial COI, tRNA(Cys), tRNA(Met), 12S, tRNA(Val), 16S, and ND1 markers showed that Orobdella masaakikuroiwai sp. n. is the sister species of the quadrannulate Orobdella whitmani Oka, 1895. Phylogenetic relationships within Orobdella masaakikuroiwai sp. n. conducted using mitochondrial markers reveled a distinction between eastern and western phylogroups.
