Abstract
Growth rate indices of postembryonic developmental morphometry of head, cephalic appendages, thorax, thoracic appendages and abdomen of life stages of four Rhynocoris species viz., R. fuscipes (F.), R. kumarii Ambrose and Livingstone, R. longifrons (Stål) and R. marginatus (F.) were analysed. The growth rate between the life stages were taken as two indices to the generic and specific diagnostic characters and interspecific affinity. Twenty four comparative growth rates between various parts of the chosen assassin bugs resulted from the growth rates of life stages were taken into consideration. The results revealed generic and specific diagnostic characters and interspecific affinity. Moreover, the analysis revealed the highest affinity between R. kumarii and R. marginatus and the least affinity between R. fuscipes and R. longifrons through exactly similar value analysis. It was further confirmed by almost similar value analysis and the dendrogram analysis by the nodes of grouped characters. The analysis of growth rates indices also revealed that R. longifrons has the highest unique characters. The above findings suggest that growth indices could be used as an intrageneric and interspecific biosystematics tool.
