title: Table 3 in Description of two new species of Desmoscolex Claparède, 1863 (Nematoda: Desmoscolecidae) from the Cassidaigne Canyon, Mediterranean Sea

description: Table 3 (continued on next page). Main differences between the species of Desmoscolex (Desmoscolex) Claparède, 1863 that share the following characteristics: 17 main rings; 9 pairs of subdorsal somatic setae on 1 st, 3 rd, 5 th, 7 th, 9 th, 11 th, 13 th and 16 th –17 th main rings; eight pairs of subventral setae located on the 2 nd, 4 th, 6 th, 8 th, 10 th, 12 th and 14 th –15 th main rings; similar head and amphid shape. If only male or female of the species are included in the table, this means that the lacking gender doesn’t present one of the aforementioned characteristics and, therefore, doesn`t belong to this group. Abbreviations: N.A. = not applicable (this is because the species was described only after female specimens); N.S. = not specified; Sd = subdorsal setae; Sv = subventral setae.
