Amphilina japonica

Klaus Rohde
Based on Dubinina 1982
Containing group: Amphilinidea

Introduction

The species is distributed in the Amur region, Japan and North America. Its hosts are Acipenser schrencki and Huso dauricus in the Amur region, Acipenser medirostris (= A. mikadoi) in Japan,and Acipenser medirostris in North America. It resembles A. foliacea closely except for slight differences in the position of gonoducts and testes follicles. Future studies may well show that the two "species" should rather be considered as different subspecies of A. foliacea. The North-American form has been described as a separate species, A. bipunctata, but it is more or less identical with A. japonica. Specimens of A. japonica reach a length of 73 mm and a width of 25 mm.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
