語言:

主要參考文獻	Zanata, A.M. and P. Camelier, 2008
附註	The type-locality of A. jacobinae is a dark headwater stream with mild water current running over pebbles, rocks and sand. Stream depth in the area sampled varied between 0.3–0.5 m and average width was around 2.0 m. Trees, palm trees, and grasses represented the marginal vegetation. The analysis of the stomach contents of one specimen revealed the presence of two distinct larvae of Diptera(Chironomidae), larvae of Trichoptera, fragments of adults of Diptera and unidentified fragments of arthropods.
