Etymology.
Refers to its distinct color pattern resembling flowers (from Latin:
macula
= spot and
flos
= flower) (
Fig. 1
).
Distribution and habitat.
This species was found only in the Amazon forest, Amazonas State,
Brazil
and in Good’s biogeographic zone 26 of Neotropical region, Highlands of Eastern
Brazil
: North Brazilian (
Good, 1974
). The climate of the area is equatorial monsoonal (Am) (
Kottek et al., 2006
). This is the first species of
Salina
with rectangular mucro described from South America, and the first species of
Salina
described from
Brazil
.
