This species was previously placed in the genus ''[[Platysticta]]'', but recent [[phylogenetic]] studies has revealed that the genus ''[[Platysticta]]'' is actually confined to [[Sri Lanka]]. For the South Indian species, formerly known as ''Platysticta deccanensis'', morphological and molecular analyses demonstrated that it does not belong to the Sri Lankan clade and a new genus ''[[Indosticta]]'' is erected to accommodate it.<ref name=Bedjanič>{{cite journal |author = Bedjanič M. |display-authors=etal | title = Taxonomy and molecular phylogeny of the Platystictidae of Sri Lanka (Insecta: Odonata) | journal = [[Zootaxa]] | volume= 4182 | issue= 1| pages = 1–80| year = 2016|doi=10.11646/zootaxa.4182.1.1 |pmid=27811665 | url=http://biotaxa.org/Zootaxa/article/view/zootaxa.4182.1.1| access-date =2017-03-13}}</ref><ref name=ifb/>

==Description and habitat==
It is a medium sized damselfly with bluish-white face and black-capped brown eyes. Its thorax is [[cinnamon]] brown with a black mid-dorsal carina.

Segment 10 is blackish-brown. Anal appendages are black.<ref name="Laidlaw">{{cite journal |last1=Laidlaw |first1=F.

Female is similar to the male; but its thorax has a bit dark patches in the dorsum and the sides. There is a narrow ante-humeral pale blue stripe and another similar blue stripe bordering the black area of the mesepimeron. Abdomen is similar to the male; but segment 8 unmarked and segment 9 with a large oval pale blue dorso-lateral spot.<ref name="Laidlaw"/><ref name="Laidlaw2"/><ref name=Fraser/>

It is known to occur close to [[Myristica swamp]]s and streams with dense riparian vegetation. [[Frank Fortescue Laidlaw|Laidlaw]] described it from the [[Kingdom of Cochin]].<ref name="Laidlaw"/> Recent studies have found populations of this species in [[Kodaku]] too.<ref name=iucn/> Commonly found resting on ferns in dark shady spots in forests.<ref name=Fraser>{{cite book|author=C FC Lt.
