Species

*Of the four other species in the P. ferrugineus  group, P. satanicus  has always been correctly identified (Wheeler, 1942; Janzen, 1969, 1973, 1974); P. mixtecus  was mistaken for P. veneficus  by Wheeler (1942) and for P. flavicornis  (= belti  ) by Janzen (1966,1973); P. janzeni  was referred to by Janzen (1973:729) as an undescribed species derived from P. ferrugineus-, and P. particeps  has received no mention in the literature.

Worker measurements (n = 69). - HL 0.99-1.33, HW 0.92-1.15, MFC 0.054-0.108, Cl 0.81-0.94, REL 0.42-0.48, REL2 0.48-0.54, 001 1.39-3.16, VI 0.60-0.78, FCI 0.054-0.101, SI 0.41-0.46, SI2 0.79-0.91, NI 0.61-0.72, PLI 0.54-0.69, PWI 0.56- 0.73, PPWI 1.34-1.70.

Worker diagnosis. - Medium-sized species ( HW >0.91; LHT 0.75-1.06) with broad head (Cl> 0.80); anterior margin of median clypeal lobe straight or weakly concave, rounded laterally; palp formula 5,3; frontal carinae well separated ( FCI > 0.05) and median lobe of antennal sclerite not strongly exposed ( FCI 2 0.45-0.69); mesosomal profile typically as in Fig. 27, with mesonotum notably inclined and with basal face of propodeum rounding gradually into declivitous face, but deviations from this pattern occur; petiole relatively short, high and wide (see relevant metrics: PLI, PWI), with a distinct anterior peduncle ( PWI 3 0.36-0.50); posterolateral angles of petiole moderately developed but not as pronounced as in P. peperi  (compare Figs. 24 and 27); postpetiole broad. Head densely punctulate, predominantly opaque or subopaque but at least weakly shining on upper third of head between ocelli and compound eye; mesosoma punctulate to punctulate-coriarious, subopaque to sublucid; posterior portions of propodeum opaque to subopaque and usually overlain by larger but weak, irregular punctures or rugulae. Petiole, postpetiole and gaster with fine piligerous punctures, sublucid. Standing pilosity common; pubescence dense but fine and appressed on most surfaces. Color variable, from light reddish- or yellowish-brown to very dark brown, gaster (and usually head) somewhat darker than the mesosoma; mandibles, scapes, fronto-clypeal complex, and apices of legs usually lighter.

Comments. - Workers and queens of P. ferrugineus  can be recognized by features of head morphology (laterally rounded median clypeal lobe, well separated frontal carinae and correspondingly limited exposure of the median lobes of the antennal sclerites, and moderately broad worker head; see Fig. 18), head sculpture (densely punctulate and (sub)opaque, but weakly shining on upper third of head between the ocelli and compound eye), and coloration (variably brown, not black or orange-brown). This species is most likely to be confused with the allopatric P. janzeni  and the partly sympatric P.flavicornis  . See under those species for more specific discussion.

Distribution and biology. - P. ferrugineus  is distributed from eastern and southern Mexico to El Salvador and Honduras (Fig. 70). It is a common species and colonies have been recorded from all swollen-thorn acacia species growing within its range, i.e. Acacia chiapensis,  A. collinsii,  A. cookii  , A. cornigera,  A. gentlei  , A. globulifera,  A. hindsii,  A. janzenii  , A. mayana  and A. sphaerocephala  . P. ferrugineus  is usually monogynous (Janzen 1967b, 1973) but a few alcohol nest series from Guatemala, belonging to apparently mature colonies (as judged by the presence of alates), contained more than one dealate queen. Janzen (1966, 1967b) conducted a massive experimental study of the interaction between P. ferrugineus  and Acacia cornigera  in Mexico, and the results of these experiments, together with copious additional observations by Janzen, showed conclusively that the ants protect the acacia from herbivores and competing plants (especially vines). P. ferrugineus  was also the subject of a study on kinship and nestmate recognition among workers (Mintzer 1982; Mintzer et al. 1985) which demonstrated a worker-based and probably inherited component to colony odor. Statements about the biology of " P. ferruginea  " from regions south of El Salvador and Honduras (e.g. Janzen 1983) refer to a different species, P. spinicola  .
