Taxonomy

Burmeister (1835) described Melucha phyllocnemis from Brazil, and Stål (1862) Melucha quadrivittis from Mexico. Dallas (1852) recorded Melucha phyllocnemis from Colombia and years later Stål (1870) synonymized Melucha quadrivittis under Melucha phyllocnemis and recorded this species from Mexico, Colombia (Nova Granada), Brazil and Paraguay. Packauskas (2010) summarized the known information and cited Melucha phyllocnemis s. lato from Bolivia, Brazil, Mexico, Colombia and Paraguay. The type material of Melucha quadrivittis was examined and compared with the original description of Melucha phyllocnemis, as well as with more than 110 specimens. Two different species were clearly recognized, therefore Melucha quadrivittis was resurrected here as valid species.
Both species share the following characters: total body length over 23.00 mm; anterolateral borders of pronotum coarsely serrate; pronotal disk yellow with four longitudinal dark lines; the humeral angles prominent, laterally expanded; and antennal segments II and III pale orange to yellowish orange.
In Melucha quadrivittis the dorsal surface of hind femur is armed with two rows of black nodules and tubercles; it is distributed from Mexico to Panama (Fig. 8). In Melucha phyllocnemis the dorsal surface of hind femur is smooth. It is distributed from Colombia to Paraguay, including Bolivia and Brazil (Fig. 9).
