Abstract

The larval morphology of the dytiscid genus Oreodytes Seidlitz was investigated through a detailed analysis of 16 Nearctic and two Palearctic species. Many structural features, especially those of chaetotaxy and porotaxy of head capsule, head appendages, legs, last abdominal segment, and urogomphi, were found to be useful for taxonomic and phylogenetic comparisons. Within the tribe Hydroporini, it is proposed that Oreodytes shares a monophyletic origin with the genera Deronectes Sharp, Scarodytes Gozis, Nebrioporus Régimbart, and Stictotarsus Zimmermann. A tentative phylogenetic reconstruction of the genus Oreodytes, based on 29 larval characteristics, is provided. The classification of members of Oreodytes indicated by larvae is shown to be only partly reconcilable with the one indicated by adults. Once subdivided into three species-groups, Oreodytes now comprises four species-groups: the O. picturatus, O. obesus, O. scitulus, and O. quadrimaculatus species-groups. Oreodytes quadrimaculatus was found to share a monophyletic origin with the members of the O. picturatus and O. scitulus species-groups. The taxonomic status of the genus-name Neonectes J. Balfour-Browne is reconsidered as the larvae of N. natrix (Sharp) and N. babai Satô are revealed to be most similar morphologically to members of the O. scitulus species-group.

Résumé

La morphologie larvaire du genre Oreodytes Seidlitz (Dytiscidae) est examinée à partir de l’étude détaillée de 16 espèces Néarctique et de deux espèces Paléarctiques. Une grande variabilité morphologique, particulièrement dans la chétotaxie et la porotaxie de la capsule céphalique, des appendices céphaliques, des pattes, du dernier segment abdominal et des urogomphes s’est révélée très utile dans la comparaison taxinomique et phylogénétique de ces espèces. Il est suggéré que, dans la tribu Hydroporini, Oreodytes partage une origine monophylétique avec les genres Deronectes Sharp, Scarodytes Gozis, Nebrioporus Régimbart, and Stictotarsus Zimmermann. Une phylogénie du genre Oreodytes est proposée à partir de l’analyse de 29 caractères larvaires. La classification ainsi générée ne s’est révélée que partiellement compatible avec celle proposée antérieurement à partir de caractéristiques morphologiques de l’adulte. Subdivisé qu’il était en trois groupes à espèces, il est maintenant proposé que le genre Oreodytes en contienne quatre : les groupes à espèces O. picturatus, O. obesus, O. scitulus et O. quadrimaculatus. L’espèce O. quadrimaculatus s’est révélée être plus étroitement liée sur le plan phylogénétique à celles des groupes à espèces O. picturatus et O. scitulus avec lesquelles elle partage une origine monophylétique. Le statut taxinomique du nom générique Neonectes J. Balfour-Browne est reconsidéré étant donné la grande ressemblance morphologique entre les larves de N. natrix (Sharp) et N. babai Satô et celle des espèces comprises dans le groupe à espèces O. scitulus.
