The second species of Biskratrombium (Trombidiformes: Microtrombidiidae) ectoparasitic on phlebotomine sandflies (Diptera: Psychodidae) from Iran.

A new species of Biskratrombium (Trombidiformes: Microtrombidiidae), B. persicumn. sp. is described and illustrated, from Fars province, southern Iran. Biskratrombium persicum larvae are ectoparasites of the adults of Phlebotomus (Paraphlebotomus) alexandri (Sinton, 1928), P. (Phlebotomus) papatasi (Scopoli, 1786) and Sergentomyia (Sergentomyia) mervynae (Pringle, 1953) (Diptera: Psychodidae). Fars province is considered as a significant focus of leishmaniasis, a disease which is mostly associated with rural areas; these areas offer favorable habitats to the phlebotomine sandflies due to limited sanitation. This study was performed to identify the natural enemies of sandflies (as leishmania disease vectors) in this region. In this research, B. persicum larvae were removed from their sandfly hosts collected from foci of leishmaniasis (e.g., sheep and goat keeping locations) using sticky traps. Also, the abundance of sandflies infested with the parasitic mite was calculated. Some morphological abnormalities in the species are noted and world parasitengone mites parasitizing phlebotomine sandflies are reviewed.
