About Esme mudiensis Fraser, 1931
Esme mudiensis Fraser, 1931 is a medium-sized damselfly. Both males and females have black-capped blue eyes. The thorax is velvet-black on the dorsum, and azure blue on the sides. The dorsum is marked with narrow ante-humeral blue stripes, and a moderately broad black stripe runs over the postero-lateral suture. The base of the thorax sides is pale blue. The wings are transparent, with black diamond-shaped pterostigma. The abdomen is primarily black, with azure blue markings on segments 1 and 2. Segments 3 through 6 have very narrow baso-dorsal annules. Segments 8 through 10 are blue, and segment 8 has a narrow black basal annule. The ventral borders of all abdominal segments are broadly black, and the anal appendages are black. Females are similar in appearance to males, but have a more robust build. This species can be easily distinguished from other Esme species by its entirely unmarked labrum, which lacks metallic blue-black markings. It is typically found along hill streams, where it perches on riparian vegetation.
