16S Gene

Relationships among, and content of, earthworm families have been controversial and unstable. Here we analyse molecular data from 14 Crassiclitellata families represented by 54 genera, the non-crassiclitellate ‘earthworms’ of the Moniligastridae, plus several clitellate outgroups. Complete 28S and 18S gene sequences and a fragment of the 16S gene analysed separately or in concatenated Bayesian analyses indicate that most previously proposed suprafamilial taxa within the Crassiclitellata are para- or polyphyletic. There is strong support for the Metagynophora, which consists of the Crassiclitellata and Moniligastridae. The most basal within-Clitellata branch leads to the small families Komarekionidae, Sparganophilidae, Kynotidae, and Biwadrilidae, found in widely separated areas. A clade composed of Lumbricidae, Ailoscolecidae, Hormogastridae, Criodrilidae and Lutodrilidae appears near the base of the tree, but Criodrilidae and Biwadrilidae are not closely related because the former is sister to the Hormogastridae + Lumbricidae clade. The Glossoscolecidae is here separated into two families, the Glossoscolecidae s.s. and the Pontoscolecidae (fam. nov.). The Megascolecidae is monophyletic within a clade including all acanthodrilid earthworms. There is strong support for the Benhamiinae (Acanthodrilidae s.l.) as sister to Acanthodrilidae + Megascolecidae, but taxon sampling within other acanthodrilid groups was not sufficient to reach further conclusions. The resulting trees support revised interpretations of morphological character evolution.’

Abstract The Labeoninae is a subfamily of the family Cyprinidae, Order Cypriniformes. Oromandibular morphology within the Labeoninae is the greatest among cyprinid fishes. Although several phylogenetic studies about labeonines have been undertaken the results have been inconsistent and a comprehensive phylogeny is needed. Further, an incongruence between morphological and molecular phylogeny requires a systematic exploration of the significance of morphological characters on the basis of the molecular phylogeny. In this study, a total of 292 nucleotide sequences from 73 individuals (representing 24 genera and 73 species) of Labeoninae were analyzed. The results of the phylogenetic analysis indicate that there are four major clades within Labeoninae and three monophyletic lineages within the fourth clade. Results of the character evolution show that all oroman-dibular morphological characters are homoplastically distributed on the molecular phylogenetic tree and suggests that these characters evolved several times during the history of labeonines. In particular, the labeonine , a specific disc on the lower lip, has been acquired three times and reversed twice. These morphological characters do not have systematic significance but can be useful for taxonomy. The results of biogeography suggest that the Labeoninae originated from Southeast Asia and separately dispersed to Africa, East Asia and South Asia.
