Description of Stenothoe lowryi sp. nov. (Crustacea: Amphipoda: Stenothoidae), from the Straits of Malacca, Malaysia

Abstract

Stenothoe lowryi sp. nov. from samples collected in an intertidal pool of Pangkor Island is described and illustrated. Diagnostic features of Stenothoe lowryi are almost exclusively related to Salman’s material of Stenothoe gallensis Walker, 1904 from the Arabian Gulf (Salman, 1985), in the shape of male gnathopod 2, outer plate of maxilla 2 with 2 articles, and moderately convex dorsal margin of male gnathopod 2. However, S. gallensis and S. lowryi sp. nov. have shown slight differences by the latter in having: 1) gnathopod 2 propodus with palmar margin moderately convex; 2) uropod 2 rami with only one robust seta on medial margin, and; 3) uropod 3 article 2 distinctly longer than article 1, proximally swollen, not rugose.
