It is a black damselfly with blue eyes. Its thorax is black, marked with yellow stripes. Wings are transparent with dark brown pterostigma. Its abdomen is black, marked with yellow. Segments 1 and 2 are yellow laterally. Segments 3 to 8 are with broad yellow basal annules. Segment 8 is with its sides yellow in addition to the basal annule. Segments 9 has yellow spot, laterally. Segment 10 is unmarked. Anal appendages are black with dark brown apices. Female is very similar to the male, but shorter and more robustly built.[1]
This species can be distinguished from other Protosticta species based on its blue eyes. It can be distinguished from P. monticola by the presence of extensive yellow markings on abdominal segments 8–9 and eye coloration. P. monticola has dorsum of abdominal segments 8–9 metallic black and black capped bluish-green eyes.[1][4]
