Aceptado el 19-VII-1999 ABSTRACT New records of Caudofoveata (Mollusca) from samplings off the coast of northern Spoin are communicated. The biogeographically new Spanish and French findings included Scu- topus ventroineatus, Falcidens vasconiensis and Prochaetoderma iberogallicum n. sp. which are systematicaily presented. RESUMEN Se presentan nuevos hallazgos de Caudofoveata (Mollusca) de muestras obtenidas frente a las costas del norte de España. En las muestras españolas y francesas que resultaron nuevas desde el punto de vista biogeográfico se recolectaron las especies Scutopus ven- trol'meatus, Falcidens vasconiensis y Prochaetoderma iberogallicum n. sp. encluyéndose en el presente trabajo descripciones de estas tres especies.. KEY WORDS: Caudofoveata, Aplacophora, new records, Spain, Prochaetoderma iberogallicum new species. PALABRAS CLAVE: Caudofoveata, Aplacophora, nuevas citas, España, Prochaetoderma iberogallicum spec. nov. INTRODUCTION The members of the small moUuscan class Caudofoveata (formerly Aplacop- hora-Chaetodermomorpha) are marine micro-omnivores measuring 2-150 mm in length which burrow within muddy sediments and have an adapted, vermi- form body with reduced pedal solé (midventral fusión of the lateral mantle rims, etc.; for general organization see Salvini-Plawen, 1985). The Caudofove- ata are currently classified into three families and at present the class inclu- des about 100 named species, 17 of which come from European waters. The knowledge of the Caudofoveata from West-European shelf regions, however, is very scanty (cf. Salvini-Plawen, 1997) and more intensive investigation is needed to provide organizational, bio- logical, and biogeographic-faunistic Information. During recent years, the survey of the Iberian fauna has resulted in intensi- fied research on coastal and off-shore habitats of the región. This initiated various scientific campaigns to collect Institut fiir Zoologie, Universitat Wien, Althanstrafie 14, A-1090 Wien IX, Austria. 77
