Treatment

Key to species of Patagonomyrmex

Workers

1 Dorsum of promesonotum with subparallel rugae to rugoreticulate, interrugae strongly granulate-punctate, dull; rugae on cephalic dorsum continue to posterior margin of head ( Figure 2 View FIGURE 2 )......................................... angustus

- Dorsum of promesonotum smooth and shining, lacking rugae; rugae on cephalic dorsum rarely continue to posterior margin of head ( Figures 6 View FIGURE 6 , 9 View FIGURE 9 ).................................................................................... 2

2 Body mostly concolorous blackish to black ( Figure 6 View FIGURE 6 )................................................. laevigatus

- Head and mesosoma light orangish-red, gaster slightly darker to brownish ( Figure 9 View FIGURE 9 )......................... odoratus

Queens

1 Mesoscutum and mesoscutellum with weak to moderately coarse longitudinal rugae, interrugae weakly to strongly granulate- punctate; inferior propodeal spines elongate, length similar to that of superior propodeal spines ( Figure 3 View FIGURE 3 )....... angustus

- Mesoscutum and mesoscutellum smooth and shiny; inferior propodeal spines triangular, much shorter than superior propodeal spines ( Figures 7 View FIGURE 7 , 10 View FIGURE 10 )................................................................................ 2

2 Body concolorous black ( Figure 7 View FIGURE 7 )................................................................ laevigatus

- Body orangish to orangish-brown ( Figure 10 View FIGURE 10 )........................................................ odoratus

Males

1 Mesopleura, metapleura, pronotal sides, and dorsum of propodeum strongly granulate, dull, with a beaded appearance; at least several hairs on ventral surface of head and those protruding from mandibles approach to exceed MOD; scapes usually long, reaching to near posterior margin of eye ( Figure 4 View FIGURE 4 ).................................................... angustus

- Mesopleura, metapleura, pronotal sides, and/or dorsum of propodeum with weak to strong rugae; no hairs on ventral surface of head or those protruding from mandibles approach MOD; scapes short, reaching only slightly beyond anterior margin of eye ( Figures 8 View FIGURE 8 , 11 View FIGURE 11 )....................................................................................... 2

2 In profile, juncture between cephalic dorsum and posterior declivity (near posterior margin of ocelli) weakly angulate to rounded; posterior declivity weakly convex to weakly concave ( Figure 8 View FIGURE 8 ).................................. laevigatus

- In profile, juncture between cephalic dorsum and posterior declivity strongly angulate; posterior declivity strongly concave ( Figure 11 View FIGURE 11 )................................................................................... odoratus
