Etymology. Refers to its distinct color pattern resembling flowers (from Latin: macula = spot and flos = flower) ( Fig. 1 View Fig ).

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.
