23. Anax indicus (Lieftinck, 1942)

Anax indicus (Lieftinck, 1942)

Family: Aeshnidae
Genus: Anax    
Species: Anax indicus (Lieftinck, 1942)
Common name: N/A
Habitat: Lakes, ponds, rivers, forest patches

Anax indicus is the the second anax species recorded from Bangladesh. Special thanks to Noppadon Makbun and Pattarawich Dawwrueng, who helped me to identify the species correctly.   


The male

Anax indicus is very similar to Anax guttatus and often confused with the similar species. However, they can be distinguished based on the banding pattern on the labdominal segments. To me, the presence of the fused postjugal yellow band on abdominal segments 6-8 is the easiest key to identify and distinguish the species from A. guttatus. According to Lieftinck (1955), the two pairs of postjugal spots are broadly fused to form a continuous band on 6, 7 & 8.
