Conservation Actions [top]

Conservation Actions: This species has already been assessed but we have no more information than for the previous assessment in 1996. Therefore further surveys are urgently needed to check whether this species is still extant. No conservation measures are known to be in place. Further information about taxonomy, ecology, population size and distribution would also be valuable.
