Note that the name Betsabora is uncertain and recovered from locals on site for this river which is a tributary to Mangoro River. Ampanihifana may be the correct name.

Also collected with pitfall traps and from leaf-litter in Namoroka NP before the rainy season in November, indicating the species can tolerate periods when the habitats dry up without immediately seeking new water. We collected the largest series at Betsabora River at an elevation of 940 m.

The river site consisted of grassy, vegetation-rich margins, bays and side pools, further described in
