Andaniexis abyssi (Boeck, 1871); A. americana Berge et al., 2001; A. andaniexis n.sp.; A. eilae Berge & Vader, 1997; A. elinae n.sp.; A. gloriosa Berge et al., 2001; A. gracilis Berge & Vader, 1997; A. lupus Berge & Vader, 1997; A. mimonectes Ruffo, 1975; A. oculata Birstein & Vinogradov, 1970; A. ollii Berge et al., 2000; A. spinescens (Alcock, 1894); A. spongicola Pirlot, 1933; A. stylifer Birstein & Vinogradov, 1960; A. subabyssi Birstein & Vinogradov, 1955; A. tridentata Ledoyer, 1986.
Species found in the area. Andaniexis andaniexis n.sp. and A. elinae n.sp.
Remarks. These are the first records of Andaniexis in the area, although the genus has previously been recorded east of Papua New Guinea (A. stylifer).
As is evident from Table 1, two of the species within the genus (A. eilae and A. spongicola) possess a cleft telson, and do thus seem to be more closely related to the genus Glorandaniotes. Furthermore, the two species A. spinescens and A. tridentata have a dorsal carina on pleonites 1–3, and thus seem to be related to the genus Parandaniexis. However, pending a revision of the entire family (Berge & Vader, 2001b), no changes are here made in the classification of these species.
