| Abstract |
A hemiarthrine bopyrid, Quadripediphryxus mayuzumii gen. et sp. nov. (Isopoda: Epicaridea: Bopyridae), is described based on a pair of specimens infesting the ventral surface of the abdomen of a snapping shrimp, Synalpheus streptodactylus Coutière, 1905 (Decapoda: Caridea: Alpheidae). The shrimp was collected from ornamental coral rock of an unidentified species of Poritidae (Cnidaria: Anthozoa) from Ehime Prefecture, Japan. The female of the new genus is similar to those in the genera Hemiphryxus Bruce, 1978, Eriphrixus Markham, 1990, and Micropodiphryxus Boyko, 2012, in having seven and four pereopods on the concave and convex sides of the body, respectively. However, female of the new genus can be distinguished from those in the other genera by the presence of a tiny triangular pleotelson bearing uropods. This finding represents the 12th species of hemiarthrine bopyrids found infesting the abdomen of caridean shrimps recorded from Japan. |
