This species is known only from a single specimen, collected at around 7m asl near Rockstone along the Essequibo River, upper Demerara-Berbice (formerly Mazaruni Potaro) District, Guyana. There does not appear to be any reason why this species should not occur more widely, but apparently the species has not been searched for since the original specimen was collected.
