Observations
. – The
type
collection has no indication of origin other than “Central
Madagascar
”, but in the
Flore
de
Madagascar
et des Comores
(
MOLDENKE, 1956
), a second collection was cited for the species –
Baron
6889
(K [
K0006
07528]), collected at “Ankavandra” a small town in the
Manambolo River valley
in the
Menabe Region of Toliara Province. The
discovery of a third specimen,
Du Puy
MB733
(MO-3846948, P [
P00075324
]), collected recently and with precise locality just
40 km
SW of Ankavandra
, helps to confirm the species as a likely highly-restricted endemic, possibly confined to the area just to the east of the
Bemaraha
protected area (
Fig. 1
).
Conservation status.
–With only three collections known (AOO of
27 km
2
), two of which dating back to acentury and only one recent, all of them falling outside the Protected Area network,
Rotheca mirabilis
can be assessed as “Critically Endangered” [CR 2ab(i,ii,iii,iv)] following the IUCN Red List Categories and Criteria (
IUCN, 2012
) (calculation following
CALLMANDER & al., 2007
).
