    L’analisi conchigliare ha rivelato l’esistenza, nelle acque del Brasile, di ottospecie appartenenti al Genere Caecum, Suttogenere Brochina: Caecum antillarum Carpenter, 1858, C. someri de Folin, 1867, C.achironum de Folin, 1867, C. circumvolutum de Folin, 1867, C.multicostatum de Folin, 1867, C. strigosum de Folin, 1867, C. marmoratum de Folin, 1870 and C. lineicinctum de Folin, 1879. Il ritrovamento di quest’ultimo è il primo per il Brasile. Queste otto specie vengono discusse, sono fornite alcune sinonimie e ne sono proposte altre nuove. Sono inoltre fornite fotografie al Microscopio Elettronico a Scansione (MES)dei seguenti esemplari-tipo: gli olotipi rispettivamente di C. venosum de Folin, 1867, C. lineicinctum de Folin, 1879, e C. butoti De Jong & Coomans, 1988; paratipi di Caecum antillarum Carpenter, 1858 e C.johnsoni Winkley, 1908; sintipi di C. heladum Olsson & Harbison, 1954; e lectotipi (qui designati) di C.achironum de Folin, 1868, C. carmenensis de Folin, 1870, C. marmoratum de Folin, 1870, C. veracruzanum de Folin, 1870, C. vestitum de Folin, 1870, C. limpidum de Folin 1874 e C. subornatum de Folin, 1874.

    Conchological analysis revealed the existence of eight species belonging to the genus Caecum, subgenus Brochina in Brazilian waters: Caecum antillarum Carpenter, 1858, C. someri de Folin, 1867, C. achironum de Folin, 1867, C. circumvolutum de Folin, 1867, C. multicostatum de Folin, 1867, C.strigosum de Folin, 1867, C. marmoratum de Folin, 1870 and C. lineicinctum de Folin, 1879. The record of the latter is the first from Brazil. The eight species are discussed, established synonymies reported, and some new synonymies proposed. Scanning electron microscope illustrations are provided of the following type-specimens: the holotipe of C. venosum de Folin, 1867, C. lineicinctum de Folin, 1879, and C. butoti De Jong & Coomans, 1988; paratypes of Caecum antillarum Carpenter, 1858 and C. johnsoni Winkley, 1908; syntypes of C.heladum Olsson & Harbison, 1954; and lectotypes (herein designated) of C. achironum de Folin, 1868, C.carmenensis de Folin, 1870, C. marmoratum de Folin, 1870, C. veracruzanum de Folin, 1870, C. vestitum de Folin, 1870, C. limpidum de Folin 1874 and C. subornatum de Folin, 1874.
