Phleobum periplanae sp. nov. and Neohirmorcystis canchipurae sp. nov. (Aplicomplexa: Eugregarinida) from Manipur, India

During 2012–2018, a survey was conducted for the protozoan parasites in valley districts of Manipur. Cockroaches were collected using Sweep-netting methods and dissected. Fresh and permanent slides of collected protozoa from the gut; the sample insect were prepared using Haedenhain's iron, haematoxylin, Giemsa and Eosin stains. Mean, standard deviation and percent of co-efficient of variations are calculated. Two new Eugregarine protozoans namely, Phleobum periplanae sp. nov and Neohirmorcystis canchipurae sp. nov. were revealed new to science. Only 9 species of Phleobum protozoa has been identified so far. The present study added a new species to this group of protozoa. Phleobum periplanae sp. nov. is characterized by spherical epimerite which measures 14.7 – 32.6 µm while the protomerite is broadly ovoid, covered by a thick pellicle which measure 26.9 – 56.9 µm. Fresh gametocytes are yellowish- orange and ellipsoidal. A new species of Neohirmocystis is described here. Only a few species of Neohirmocystis protozoa have been identified. Neohirmocystis canchipurae sp. nov. is characterised by lack of epimerites with atrophozoite length of (159.6-192.6) µm. Gametocyst dehisces by simple rupture releasing spherical spores.
