      Anopheles fluviatilis andAn. minimus complexes, each comprising of at least three sibling species, are closely related and important malaria vectors in Oriental Region. RecentlyAn. fluviatilis species S, which is a highly efficient malaria vector in India, has been made conspecific withAn. minimus species C (senior synonym) on the basis of homology in 335 base pair nucleotide sequence of D3 domain of 28S ribosomal DNA(rDNA). We examined the conspecificity of these two nominal species by obtaining and analysing the DNA sequences of nuclear ribosomal loci internal transcribed spacer 2 (ITS2) and D2-D3 domain of 28S rDNA (28S-D2/D3) from those ofAn. fluviatilis S andAn. minimus C. We found that the sequences ofAn. fluviatilis S are appreciably different from those ofAn. minimus C with pair-wise distance (Kimura-2-parametre model) of 3.6 and 0.7% for loci ITS2 and 28S-D2/D3, respectively. Pair-wise distance and phylogenetic analyses using ITS2 sequences of members of Minimus and Fluviatilis Complexes revealedthat An. fluviatilis S is distantly related toAn. minimus C as compared to any other members of the Fluviatilis Complex. These findings suggest that the two nominal species,An. fluviatilis S andAn. minimus C, do not merit synonymy. The study also confirms that the reported speciesAn. fluviatilis X is synonym with species S.

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
