Concatenated phylogenetic tree of selected species of Macrobrachium representing wide geographical distribution of the group, based on the method of maximum likelihood of the 16S rDNA, COI mtDNA, 18S nDNA and H3 nDNA genes. Numbers on nodes refer to significance values of 1000 bootstrap replicates; values ≤ 50% are not shown. ARG: Argentina; BR: Brazil; CH: Chile; CR: Costa Rica; JAP: Japan; MX: México; NIG: Nigeria; PN: Panamá; VZ: Venezuela. ALD: Abbreviated larval development. ELD: Extended larval development. Blue: species from Indo-Pacific. Red: species from Africa. Green: former Cryphiops species.
