Descripción
Descriptions of the larvae of Lancetes angusticollis (Curtis), L. lanceolatus (Clark), L. subseriatus Zimmermann, L. flavoscutatus Enderlein, L. delkeskampi Ríha, and L nigriceps (Erichson) are provided. Characters from larval morphology are analyzed to infer the phylogenetic relationships of the genus Lancetes Sharp with other genera of Dytiscidae. A parsimony analysis based on 51 informative larval characteristics was conducted with the program NONA. The most parsimonious tree supports a sister-group relationship between the genus Lancetes and members of the subfamily Dytiscinae. The only unambiguous synapomorphy in support of this hypothesis is the secondary subdivision of some cephalic appendages. Other putative synapomorphies are the proximal articulation of the primary seta CO7 both on meso- and meta-coxa and the presence of additional primary setae on the ventral margin of the tibiae. Based on several character states including the presence of multifragmented urogomphi, the genus Lancetes is monophyletic.
Les stades larvaires des espbces Luncetes angusticollis (Curtis), L. lanceolatus (Clark), L. subseriatus Zimmermann, L. pavoscutatus Enderlein, L. delkeskampi Riha, and L. nigriceps (Erichson) sont decrits. Une analyse par parcimonie de 51 caracteres larvaires significatifs fut effectuee B l'aide du logiciel NONA afin de determiner la position phylogCnBtique du genre Lancetes Sharp parmi les Dytiscidae. L'arbre les plus parcimonieux suggBe que le genre Luncetes est le groupe consoeur de la sous-famille Dytiscinae. Cette hypothbse est fortement supportee par la division secondaire de certains articles des appendices cephaliques, caractbre presumement synapomorphique, ainsi que par la position proximale de la soie primaire C07 sur la meso- et la mCta-coxa et par la presence de soies primaires additionnelles sur la marge ventrale des tibias. L'origine monophylCtique du genre Luncetes elle-m&me supportke par plusieurs caractkres parmi lesquels la presence d'un urogomphe plurifragmentk.
