Gymnomeropsylla N. gen. (Siphonaptera : Pygiopsyllidae) from Sulawesi, Indonesia, with the description of two new species

摘要

Compared to related genera, this new flea genus is characterized by the absence, or presence of very few, bristles on the external surface of femur I and especially by the morphology of the apex of sternite IX in the male, which is hyaline and lacks spiniform bristles. The two new species, G. bunomydis and G. margaretamydis, are distinguished from each other by the structure of the genitalia, and the presence of numerous erect bristles on the thorax and abdominal tergites of the latter species. Both of these new species parasitize murine rodents that are endemic to Sulawesi; G. bunomydis was collected mainly from Bunomys chrysocomus and G. margaretamydis only from Margaretamys parvus.
