Abstract

We show that Lasioglossum mediterraneum (Blüthgen) (Hymenoptera, Halictidae) is a species distinct from L. laticeps (Schenck) based upon electrophoretic analysis of 39 allozyme loci for sympatric populations collected from the Dordogne region of France. The genetic identity between the two is below average for sibling species of insects: no fewer than 10 fixed allelic differences were found. In contrast, allopatric L. laticeps populations (from the Dordogne and Paris) are genetically almost identical (I = 0.998). Heterozygosity estimates for both species are low, as is often the case with Hymenoptera. Diagnostic characteristics that can be used to separate the two species are described. A phylogeny for nine species of the subgenus Evylaeus is constructed from allozyme data.

Résumé

Nous démontrons ici que Lasioglossum mediterraneum (Blüthgen) (Hymenoptera, Halictidae) est une espèce distincte de L. laticeps (Schenck) en nous basant sur les résultats de l’électrophorèse de 39 allozymes de populations sympatriques échantillonnées dans la région de la Dordogne, France. L’identité génétique des deux espèces est au-dessous de la moyenne pour des espèces soeurs; pas moins de 10 différences d’allèles fixes ont été trouvées. Par ailleurs, des populations allopatriques de L. laticeps (de la Dordogne et de la région de Paris) se sont avérées presque identiques génétiquement (I = 0,998). L’estimation de l’hétérozygotie chez les deux espèces a donné des valeurs faibles, comme c’est souvent le cas chez des Hyménoptères. Les caractéristiques diagnostiques qui permettent de reconnaître les deux espèces sont décrites. Une phylogénie de neuf espèces du sous-genre Evylaeus a été reconstituée d’après les données sur les allozymes.
