Description of Lentistivalius philippinensis, a new species of flea (Siphonaptera, Pygiosyllomorpha, Stivaliidae), and new records of Ascodipterinae (Streblidae) on bats and other small mammals from Luzon, The Philippines.

During May 2009 and July 2011, we collected 357 mammals and examined each for ectoparasites. Among the ectoparasites collected, a new species of flea was discovered. This new species, Lentistivalius philippinensis, is described from the male sex only. Two males were recovered from two specimens of the soricid Crocidura grayi Dobson in Municipality Maria Aurora, Aurora Province, Luzon, Philippines. Additional fleas included Thaumapsylla breviceps orientalis Smit, Thaumapsylla longiforceps Traub, and Ischnopsyllus indicus Jordan. Although the latter species is common in Japan and documented in Guam (as well as mainland Southeast Asia) also on Pipistrellus javanicus (Gray), Ischnopsyllus indicus represents a new record in the Philippine Islands. The ascodipterinae (Streblidae) Maabella stomalata and Ascodipteron speiserianum Muir collected from Rhinolophus inops K. Andersen and Rhinolophus subrufus K. Andersen, respectively, also represent new host records. A key to the species of the flea genus Lentistivalius Traub is provided.
