Abstract

Microsporidia are common pathogens of insects and sometimes are considered as a candidate in the biological control of mosquitoes. Recently a microsporidium infection was discovered in Anopheles superpictus (Diptera: Culicidae) larvae, in Iran. The responsible agent belonged to the genus Parathelohania (Microsporidia: Amblyosporidae). This study has been carried out to identify its identity at the species level. Fresh infected larvae were collected from the type locality, Kiar district, in Chahar Mahal and Bakhtiari province, at the central western of Iran. Superficial and the internal ultrastructure of the recovered spores were explored by scanning and transmission electron microscopy, respectively. Molecular techniques were also employed to amplify parts of its ssu rDNA. The obtained data were compared with the available information of congener species and other closely related microsporidia to elucidate evolutionary relationship. A small apical depression and two posterolateral ridges extending backward from a pear shaped anterior body mass were notable under scanning electron microscopy. Transmission electron microscopy revealed 3 broad and 3–4 narrow coils in the either side of spores, respectively. The sequence of a 1062 nucleotide fragment of ssu rDNA was determined by means of PCR technique. This study indicates that the microsporidium infecting An. superpictus differs from other previously described species in the genus Parathelohania. It means that the microsporidium infecting An. superpictus is a new species and hereby it is called Parathelohania iranica. Further work is necessary to clarify its life cycle and probable value in the biological control of mosquitoes.
