Occurrence and distribution of some stomatopod crustaceans in the western Mediterranean.- Stomatopod crustaceans have been very little studied in the . With the exception of mantis, the only common and abundant , nine other stomatopods have been recorded so far in Mediterranean waters, al1 of them very scarcely. The occurrence of some of these species is recorded herein based mainly on data collected during fishery research surveys in the western Mediterranean. Parasquilla ferussaci is recorded for the first time from the Balearic Islands, heing its first record in the Iberian Mediterranean waters. The second Mediterranean record of Platysquilloides lillyae, the sixth for the species, is based on a specimen collected off the Maresme region (Catalonia). New data on the distribution of pallidus and R. desmaresti in the Catalano-Balearic Sea are provided.

Key words: Parasquillaferussaci, Platysquilloides lillyae, Rissoides pallidus, , Stomatopoda, Westem Mediterranean.

A total of ten species of stomatopod The objective of the present paper is to crustaceans are known from Mediterranean record the occurrence of severa1 little known waters (VALLADARES,1988; FROGLIA& species of stomatopods off the Balearic and MANNING,1989). Notwithstanding, this Catalan coasts, providing new data on their fauna has been little studied in the distribution. Mediterranean Sea and, indeed, in European waters. With the exception of the (Linnaeus), MATERIAL AND METHODS common in the muddy benthos near deltas of the Mediterranean (ABELLÓ& SARDÁ, The material studied has been collected 1989; ABELLÓ& MART~N,1993), data on during severa1 research surveys performed the occurrence and distribution of other between the years 1991 and 1993 using stomatopod crustaceans in the western different methodologies: trawl nets, dredges Misc.
