Gongrosira onusta Zeller, 1873: 191–192 (type locality: Elephant Point, Pegu, Burma).—De Toni, 1889: 254.
INDIAN OCEAN DISTRIBUTION: Burma.
Note: Considering the habitat (on submerged trunks in a mangrove swamp) and the fact that Gongrosira Kützing (1843b: 281) is known for certain only from fresh water, it seems unlikely that this species is correctly assigned.
