Original Paper


Three new species of batrachotrematid trematodes from the small paa frog, Nanorana minica, collected in Uttarakhand, India are described and illustrated: Batrachotrema korbaensis sp. nov., Opisthioparorchis dehradunensis sp. nov. and Opisthioparorchis nanoranae sp. nov. The new species are assigned to genera based on presence or absence of cuticular spines; absent in Batrachotrema, present in Opisthioparorchis. Five species are assigned to Batrachotrema, which are separated by position of genital pore, location of testes and host; B. korbaensis differs from previously described species in that it is the only species from an anuran host with testes in the 4th quarter of the body. Ten species are assigned to Opisthioparorchis, which are separated by testes position, extent of vitellaria, and oral sucker-acetabulum ratio. O. nanoranae sp. nov. is the only species possessing tandem testes. Two species, O. dehradunensis sp. nov. and O. yaanensis, possess oblique testes, the remaining 7 species have symmetrical testes. Opisthioparorchis dehradunensis sp. nov. is distinguished from O. nanoranae sp. nov. by testes orientation; oblique in O. dehradunensis sp. nov., tandem in O. nanoranae sp. nov.
