Ecballocystopsis (Oocystaceae, Chlorellales, Trebouxiophyceae) is a rare green algal genus, represented by only five taxa: E. dichotoma var. dichotoma from China and E. indica, E. desikacharyi, E. himalayensis and E. dichotoma var. minuta from India. Here we propose the novel variety E. dichotoma var. anandii from Jharkhand, synonymization of E. himalayensis with E. dichotoma and erection of E. dichotoma var. minuta to a separate species as E. minuta stat. et comb. nov. These taxonomic changes are well supported by the results of a multivariate analysis based on a numerical taxonomic approach. Cluster analysis (CA), principal component analysis (PCA) and principal coordinates analysis (PCoA) were performed to resolve the species delimitation ambiguity and supplement the morphology‐based classification of the genus. Ecballocystopsis himalayensis and E. dichotoma grouped in a single cluster along with the proposed new variety, while E. indica, E. desikacharyi and E. minuta formed separate clusters. An identification key to the species of the genus Ecballocystopsis is also presented. [ABSTRACT FROM AUTHOR]

Allele frequencies and haplotype diversity of 17 Y-chromosomal short tandem repeat (STR) loci included in Y-filer™ PCR amplification kit were studied in 120 Garo and 139 Santal male individuals residing in two distinct regions of Bangladesh. A total of 99 different haplotypes from Garo and 129 different haplotypes from Santal individuals were observed with a corresponding discrimination capacity (DC) of 0.825 and 0.928, respectively. A comparison of the studied data with the published data from Y-STR haplotype reference database (YHRD) based on AMOVA revealed that the Garo population is closely related to Tripuri population from Tripura, India and Santal population moderately close to Munda population from Jharkhand, India. The mainstream Bengali population resides at a significant genetic distance from these two studied populations. [ABSTRACT FROM AUTHOR]
