Remarks: Kemp (1924) documented this species from 300ft – 350ft inside the Cave and commented that deeper inside the Cave “ it occurred more sparingly; it was found in some numbers in the main channel between 600 and 1300 ft. and was taken in the streams at 1700 and 2000 ft. A single individual was captured at 3200ft.” We found this species only within the twilight zone of the Siju Cave, though they are abundant in the stream outside the Cave.
