Mantellas are not darts. They are similar, but they are not darts Depending on the line of taxonomy you follow they are either in the family Ranidae (true frogs) or in their own family, Mantellidae.

"Hyla" on its own would be a genus of treefrogs, like Hyla versicolor, H. arborea, H. gratiosa, and so on. In this case Hylarana erythraea is not a treefrog.

Litoria subglandulosa is a close relative to Litoria caerulea, so your on the right trail.

Let me know when you give up and I will reveal the answers.
