| Nucleotide sequences of the D3 expansion segment of the 28S rDNA gene were used to reconstruct evolutionary relationships within the Adenophorea. Neighbor-joining and parsimony analyses of representatives of most major taxa revealed a paraphyletic Adenophorea (p = 0.0005). Within Adenophorea, the Enoplia, Enoplida, and Enoplina were paraphyletic (p = 0.0024, 0.0014, and 0.0120, respectively). A major division was evident within the Enoplida, with one lineage consisting of a basal Thoracostomopsidae and Enoplidae, and a second lineage consisting of Oncholaimidae and Encheliididae. Tripyloidina clustered close to the basal enoplid branch and formed a monophyletic taxon. Although appearing as paraphyletic in the maximum-parsimony and neighbor-joining trees,... |

| The current classification system for the Monocelididae which is based on the character "presence or absence of an accessory prostatoid organ" divides the family into two subfamilies, namely the Minoninae and the Monocelididinae. However, other characters relating to the structure of the male copulatory bulb and to karyotypes do not support this division. Monocelidid male copulatory bulbs can be either of the simplex or the duplex-type, and if this character is mapped onto the current classification, then both subfamilies contain species with either type of copulatory bulb. We therefore decided to construct an independent phylogeny for the Monocelididae using nucleotide-sequence data of the gene coding for the 26/28S rDNA. Distance and parsimony-based... |
