Reproductive Isolation and Taxonomic Differentiation of Romanomermis culicivorax Ross and Smith, 1976 and R. communensis Galloway and Brust, 1979
Abstract
The infertility of hybrid progeny of Romanomermis communensis and R. culicivorax supports their retention as distinct species. Their taxonomic separation on the basis of morphometric data and possession of a cone-shaped spicule guide is rejected. However, differences in the enzyme patterns of peptidase and phosphoglucomutase and the restriction fragment length differences in repetitive genomic DNA provide sensitive diagnostic characters that confirm the differentiation into two species. Key words: reproductive isolation, Romanomermis communensis, R. culicivorax, taxonomy.Downloads
