A new Neotropical ant species of genus Linepithema Mayr (Hymenoptera, Formicidae, Dolichoderinae) with partial revision of the L.fuscum group based on males.

ABSTRACT: The genus Linepithema was erected by Mayr (1866) for his male-based species L.fuscum. In this study a new species is described also based on male morphology, L.paulistanasp. nov., collected in the city of São Paulo, Brazil, which is attributed to the fuscum group (Formicidae: Dolichoderinae). Linepithemapaulistanasp. nov. is the only species of fuscum group present in the eastern part of South America. It is easily distinguishable from the other species of the group because of the presence of a triangular volsellar tooth, which is distally situated between the digitus and the basivolsellar process. By using SEM and optical microscopy, the external genitalia of L.paulistanasp. nov. were analyzed and illustrated and some c
