Clarkhydrus sp.

Comments.

This species was collected at levels 4 (rivers 1 and 2, 1,448-1,619 m) and 5 (river 1, 1,763 m) on substrates of macrophytes and leaf packs, and was present throughout sampling months (February 2018 through February 2019, dry and rainy season). Specimens did not match known described species of the genus; however, they are close to C. decemsignatus , yet male genital morphology differs.
