The present paper deals with the first descriptions of the females of two endemic Gomphid dragonflies of India, namely Cyclogomphus heterostylus Selys, 1854 and Ictinogomphus distinctus Ram, 1985, based on the specimens collected from Maharashtra, India. Additionally present status of Cyclogomphus wilkinsi Fraser, 1926 in India is also discussed.

In current time, the Forest Owlet is endemic to central India, and its range is encompassed within the ranges of the Jungle Owlet (distributed through South Asia) and Spotted Owlet (distributed through Iran, South and Southeast Asia). Another phylogenetically close species, Little Owl which is largely Palearctic in distribution, is hypothesized to have undergone severe range reduction during the Last Glacial Maximum, showing a postglacial expansion.

Unfortunately, many of these species severely lack basic research, resulting in poor conservation strategies. The phylogenetic relationship of the Critically Endangered Forest Owlet Heteroglaux blewitti has been the subject of a century-old debate.
