Villiers’ Emerald was described in 1984; it is endemic to the island of Mwali (Mohéli) in the Comoro Islands.
The species is only known from one locality that seems to be highly degraded now, it has not been found in recent field studies and might well be extinct.

Pauliani’s Nesolestes Damselfly was described in 1951; it is known only from the type specimen which was collected in 1947 on the island of Mwali (Mohéli), the smallest of the three main islands of the Comoro Islands.
The amount of suitable habitat is continuously declining due to deforestation and urban pollution and this species might well be extinct.
