Morphological evaluation of Gomphidae dragonflies of Hazara region Pakistan through principle component analysis

Sardar Azhar Mehmood, Mian Said Khan, Ahmed Zia, Farid Asif Shaheen

Current study was conducted on Gomphidae dragonflies in Hazara region of Pakistan. A total 125 specimens were collected and identified in to 8 species and 6 genera. Five morphometric parameters were based to evaluate the variations and similarities among species. The results were obtained using the principle component analysis. Components PC1 and PC2 were observed positive correlated with all variables. Highest Euclidean distance was observed (5.14) between Platygomphus dolabratus and Anormogomphus kiritschenkoi, while the lowest Euclidean distance was found (0.27) between Onychogomphus biforceps and O. bistrigatus. Cladogram was showed two groups I and II and result of Line plot highly support the cladogram. Case wise variability showed 6(75%) and 2(25%) species were conspired in the same region between (0 to +2.5) and (0 to -2.5) respectively. The component/factors variability plot was observed the cumulative share for PC1 (60.60%) and PC2 (36.82%) respectively. Morphometry and its findings are very important for identification purposes.
