Other included species Attemsostreptus reflexus Akkari & Enghoff, 2019 Attemsostreptus cataractae Enghoff sp. nov. Attemsostreptus julostriatus Enghoff sp. nov. Attemsostreptus leptoptilos Enghoff sp. nov. Diagnosis The discovery of three new species in the genus necessitates a revision of the genus diagnosis proposed by Akkari & Enghoff (2019) . Species of Attemsostreptus differ from other Spirostreptidae by the combination of the following characters: anterior margin of collum unmodified, metazonites with longitudinal ridges (carinae), or at least striae along the entire perimeter of the body (trachystreptoform habitus); prefemoral lobes of first pair of male legs triangular, covered with minute short spines; tip of gonopod coxal metaplica folded back on anterior side, forming a ‘roof’ or canopy over gonocoel; a long to very long pointed lateroapical metaplical process; gonopod telopodite long and slender, with a long to very long, pointed antetorsal process; posttorsal part of telopodite very long and thin, forming loose coils; telopodite ending in two short branches of subequal length, one broad and more or less serrated, the other acuminate.
