Filellum bouvieri : Peña Cantero et al. 1998 : 301 . Type series. We found no information on the type specimens of Filellum bouvieri Jullien, 1880 , and none may exist. Distribution. Filellum bouvieri was only recorded from the Cape Verde Islands in its original description by Jullien (1880) . Remarks. Filellum bouvieri was described by Jullien (1880: 291) from material collected in Cape Verde Islands, diagnosed by the hydrorhizae “grèles, cornées, non entrelacées”, with branching points “naissant ordinairement à angle droit les uns des autres” and “tortueux, alternes”. There is a single hydrotheca at the ramification diagnosed as “pédonculée” and composed of two parts, “l'une rampante et postérieure est renflée en son milieu” and “l'autre dressée quelquefois jusqu'à angle droit sur la première”. The hydrotheca is “cylindrique” and with “une ouverture un peu évasée”. According to Jullien (1880: 292) , F. bouvieri is different from F. s e r p e n s because it has hydrorhizae “beaucoup plus grêles” and hydrothecae “plus coudées”. However, as remarked by Peña Cantero et al. (1998 : 301), the material described by Jullien (1880) was not fertile and trophosomal characters are not enough to distinguish it from the other species of Filellum . Specimens of F. bouvieri were never collected since the original description and, therefore, the validity of this species is dubious (see also Peña Cantero et al. 1998 : 301). We consider it as species inquirenda .
