Abstract
- A new species of callianassid ghost shrimp, Paraglypturus tonganus sp. nov., is described and illustrated on the basis of five specimens that were collected from sediments in a vent field of the Tonga Arc, south-western Pacific Ocean. This new species is morphologically very similar to P. calderus Turkay & Sakai, 1995, the type species of the genus Paraglypturus Turkay & Sakai, 1995. It differs from P. calderus mainly in the absence (vs. presence in P. calderus) of an anterolateral row of setal pores on the carapace; the endopod of the second maxilliped, with a dactylus bearing stiff and thick serrate setae at the apex (vs. without in P. calderus); a yellow circular structure located on the ventral surface on the uropodal endopod (vs. on the dorsal surface on the uropodal exopod in P. calderus); and the articulation structure of the first pleopod in males (uniarticulate in P. tonganus vs. biarticulate in P. calderus). The new species is the first record of a ghost shrimp from a vent field of the Tonga Arc, and also the second reported species of the genus Paraglypturus.
