Bradinopyga konkanensis sp. nov. is described based on three males and one female collected from the coastal region of Maharashtra, India. Important characters are illustrated and compared with morphologically similar species Bradinopyga geminata (Rambur, 1842), Indothemis carnatica (Fabricius, 1798). and Indothemis limbata sita Campion, 1923. Bradinopyga konkanensis sp. nov. is so far the only Western Ghats endemic Odonata species associated with lateritic coastal habitats.

1. Damselflies often show intra-specific colour variation, which may represent genetic polymorphism or age-related (ontogenic) colour changes.

2. Such variation has distinct implications for the species{\textquoteright} ecology and evolution. Colour variation in females of the damselfly Agriocnemis pygmaea was studied, which range from blue male-like individuals (andromorphs) to those with a distinct red colour (heteromorphs). From preliminary observations, it was hypothesised that this species exhibits ontogenic colour change from heteromorph to andromorph coloration.

3. Mark-recapture experiments and egg counts of dissected females suggested that immature females are heteromorphic and gradually begin to resemble males as they attain sexual maturity.

4. Reflectance spectra of field-caught individuals indicated that, although males are indistinguishable from andromorphs, they could be easily differentiated from heteromorphs.

5. Finally, field observations and mate choice experiments showed that males rarely attempt to mate with heteromorphic females and prefer andromorphs. Together, this study{\textquoteright}s results suggest that the observed colour variation in A. pygmaea females is ontogenic and is associated with sexual maturity.
