Comments: The specimens were collected from two sites at 1340 m elevation in two small tributaries
  of the Río Calam in the Ulúa drainage.  The creeks were 3-5 m wide,  20-40 cm deep and canopy cover was c. 60%; substratum dominated by large cobble, and creek margins featured emergent macrophytes where the species was collected.  Associated fishes <i>Alfaro huberi</i>, <i>Oreochromis niloticus</i> and <i>Rhamdia laticauda</i> (Ref. 84033).
