Scalmogomphus bistrigatus & schmidti

Family Gomphidae

Scalmogomphus bistrigatus 

Hagen, 1854

Elevation 400-1800m

Abdomen Length 38mm

Location Pokhara, Godavari, 

Previously, Onychogomphus bistrigatus (Hagen in Selys, 1854). I found this newly emerged male next to a stream in a shaded forest at Hemja off the Baglung Road outside of Pokhara. There was a small patch of good forest on one side of the Hemja Khola (stream) with a small seepage. This was the same place where I found Drepanosticta carmichaeli. I am not sure of the habits or seasonality of this one.

A recent find in Godavari, 2019 & 2020. This gomphid is usually seen in Pokhara at 800m and a bit higher. I have seen it in June in Pokhara and in July and September in Godavari. It is a Himalayan species found in NW India, NE India, and Nepal.

Scalmogomphus schmidti

Fraser 1937

Elevation 800 - 1600m

Abdomen length 40mm

Formerly called Onychogompus. I have only seen this one time on a stream above the Rani Mahal outside of Tansen. The identification of this one was based on Asahina 1988, his specimen taken from Tatopani, from the facial markings and thorax markings. I don't have any information on its habits. I have only seen it once and have two photos. It seems to be suited to the Himalayan region. There is an easy comparison to be made from the photo below with the photo above of S. bistrigatus.
