. Medium sized species (HW 0.74–1.28, HL 0.86–1.42); head varying from somewhat elongate to rather broad (CI 0.75–1.05); eyes moderately elongate in non-mutualist species (REL 0.48–0.55), shorter in the mutualist acacia-ants (REL 0.39–0.50). Masticatory margin of mandible with 6, rarely 7, teeth; mesial tooth on basal margin closer to apicobasal angle than to proximal tooth. Palp formula 5,3, reduced to 4,3 in three species. Anterior margin of median clypeal lobe somewhat blunt-edged, in dorsal view convex, straight or concave, laterally rounded or with sharp angles. Frontal carinae separated by about basal scape width in most species but more closely contiguous in some (FCI 0.03–0.10), fusing anterolaterally with antennal sclerites. Profemur relatively robust in non-mutualist species (FI 0.42–0.46), more slender in mutualist acacia-ants (FI 0.35– 0.41). Pronotum laterally rounded. Metanotal groove weakly impressed in non-mutualists, well developed in mutualists. Basal and declivitous faces of propodeum moderately well differentiated and subequal in length, in profile the juncture between the two subangulate or gently rounded. Petiole relatively long (PL/HL 0.44–0.63), always much longer than high or wide (PLI 0.47–0. 71, PWI 0.46–0.75), small anteroventral tooth present; in four species anterior peduncle of petiole weakly differentiated and posterolateral corners of petiolar node not expanded (the presumed plesiomorphic condition), in other species petiole with distinct anterior peduncle and with expanded, subangulate posterolateral corners. Postpetiole broader than long, with small anteroventral tooth. Body sculpture varying from densely punctulate or punctulate-coriarious to coriarious-imbricate, the integument sublucid to opaque; dorsum of head never with extensive smooth, shiny interspaces (punctulae usually separated by their diameters or less); propodeum of some species overlain by a coarser but weak rugulo-punctate sculpture. Standing pilosity usually common, less abundant in non-mutualists (MSC 7–26) than mutualists (MSC 10–62), present on the scapes, head, mesosoma dorsum, petiole, postpetiole and gaster, absent from the extensor faces of tibiae (HTC 0, MTC 0). Appressed pubescence dense on most of body, including head and abdominal tergite IV. Color varying from light yellow- or orange-brown to black.
