Naushonia panamensis New species Decapoda Thalassinidae Laomediidae From The Pacific Coast Of Panama With Notes On The Genus

Naushonia panamensis is described from a Pacific Panamanian mud flat. It is the fifth described species of the genus and the first recorded from the tropical eastern Pacific. A revised key to the genus is presented. The genus Naushonia Kingsley, 1897, was reviewed recently by Goy and Pro- venzano (1979). At that time four species were known: N. crangonoides Kingsley, 1897, ranging from Woods Hole, Massachusetts, to Bogue Sound, North Caro- Hna; N. portoricensis (Rathbun, 1901) collected at Puerto Rico, Cuba, Bermuda, and Quintana Roo, Mexico; N. perrieri (Nobili, 1904) known from French So- maliland. Red Sea; and N. macginitiei (Glassell, 1938) known from La Jolla, California, and Sonora, Mexico. Goy and Provenzano (1979) were able to examine at least three specimens of each species except N. perrieri, which was unavail­ able. Apparently species in this genus are either rare or difficult to collect. The species are known from only a few specimens each and there are probably two or three additional species known from larvae only (see review by Goy and Provenzano 1979).
