title: Two new fleas (Siphonaptera: Ceratophyllidae: Leptopsyllinae) of Madagascar: Tsaractenus rodhaini n. sp. and Paractenopsyllus (Consobrinopsyllus n. subgen.) goodmani n. sp.
abstract: Following considerable sampling in Malagasy forests, two new species of endemic fleas from Madagascar are described. These are T. rodhaini n. sp. and P. goodmani n. sp., collected on small mammals. The material of T. rodhaini allows us to describe the previously unknown female of the genus Tsaractenus. We also complete the initial description of the genus with new diagnostic characters. Although it belongs to Paractenopsyllus, P. goodmani shows many unique characteristics. To help resolve certain systematic issues involving Malagasy Leptopsyllinae we introduce the new subgenus Consobrinopsyllus of Paractenopsyllus for P. goodmani. Its particular condition makes us consider valuable characters of the genus Tsaractenus. Carrying several traits of this genus, P. goodmani could constitute an intermediate step between the two endemic Malagasy leptopsylline genera. Considering these new findings the actual taxonomic position of the Malagasy genera among the Leptopsyllinae is discussed.
