Abstract

A new species of spider crab of the genus Libinia from Perú, and the first known male of Delsolaria enriquei Garth, 1973 (Crustacea, Brachyura, Majidae), by John S. Garth and Matilde Méndez G., Bull. Southern California Acad. Sci., 82(3):125-130, 1983. A new species of spider crab, genus Libinia. and the first known male of another species, Delsolaria enriquei, from among IMARPE (Instituto del Mar del Perú) collections from northern Peru are described and illustrated. The former belongs to an amphi-American genus having north and south temperate anti-tropical cognates; the latter is a Peruvian endemic. The new Libinia species is most closely related to L. mexicana Rathbun of the Gulf of California. Delsolaria, as shown by the male first pleopod of D. enriquei, is allied with Libidoclaea Milne Edwards and Lucas, an austral American genus of the subfamily Pisinae. Resumen.—Se describen e ilustran una nueva especie de cangrejo araña, Libinia peruana, y el macho de Delsolaria enriquei, no conocido anterioramente. Los ejemplares corresponden a colecciones efectuadas en el norte del Peru por una embarcacion arrastrera langostinera y durante el Crucero 7008-09 del Barco Cientifico SNP-1 del IMARPE (Instituto del Mar del Peru). La primera especie pertenece a un genero que se distribuye en ambas costas de America, la segunda especie es endemica del Peru. Libinia peruana se relaciona estrechamente con L. mexicana Rathbun, que habita el Golfo de Caiifomia. Delsolaria, por la forma del primer pleopodo del macho de D. enriquei, se relaciona con Libidoclaea Milne Edwards, un genero austral americano de la subfamilia Pisinae.
