FIGURE 5 in A taxonomic revision of the seed-harvester ant genus Pogonomyrmex (Hymenoptera: Formicidae) on Hispaniola

FIGURE 5. Geographic distribution for (A) Pogonomyrmex aterrimus (▲), P. "darlingtoni" (■), and P. saucius (●), and (B) P. schmitti (●). The bold line down the left-center of the map is the border between Haiti and the Dominican Republic; lighter lines are the first administrative divisions in each country. Both maps are drawn on the same geographic area so that distribution patterns are directly comparable.

Fig. 7 in Messor erwini sp. n., a hitherto cryptic harvester ant in the Iberian Peninsula

Fig. 7. Dendrogram solution for the morphometric data of Iberian Messor species. Sample information in the dendrogram given as follows: final species hypothesis followed by a five-digit sample code applied by the genetic lab separated by a hyphen. Two columns of rectangles represent results of the partitioning algorithms 'hclust' and 'kmeans'. Different colors distinguish species. Messor barbarus: black, M. erwini sp. n.: green, M. capitatus: blue, M. bouvieri: red.

Fig. 5 in Messor erwini sp. n., a hitherto cryptic harvester ant in the Iberian Peninsula

Fig. 5. Phylogenetic analysis based on COI of Messor barbarus, M. bouvieri, M. capitatus, and the hitherto unidentified M. erwini sp. n. with Aphaenogaster iberica, M. lobognathus, and M. chamberlini as outgroups, using the Neighbor-Joining method based on Kimura 2-parameter. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The analysis was conducted in MEGA 7.0.26 (Felsenstein 1985; Saitou and Nei 1987; Nei and Kumar 2000; Kumar et al., 2016).
