Dozens of monoclonal cultures small-celled araphid diatoms from brackish or marine habitats worldwide were analyzed using morphological observations (light and electron microscopy) molecular data (nuclear-encoded small subunit ribosomal RNA chloroplast encoded rbcL psbC). As a result, we established one new genus Gedaniella, distinguished by shared character (occlusions branched volae, projecting the apical sides areolae) some data, including five species: G. alfred-wegeneri, arenaria, boltonii, panicellus, paucistriata three combinations: flavovirens, guenter-grassii mutabilis. Additionally describe eleven novel species within existing Serratifera: S. andersonii, brevis, clavata, corallina, namibica, nosybeana, parkii, punctata, rhombica, sourniae, takanoi combination opephoroides. Furthermore, taxa combinations described other genera: such as Cratericulifera crinigera, Nanofrustulum wachnickianum, Plagiostriata baltica, Pseudostaurosira madagascariensis Stauroforma rinceana. Detailed descriptions for are also provided: shiloi, Opephora pacifica elliptica. This study strongly suggests that complete biodiversity araphids is still far known, many currently placed in need to be further re-investigated.
