(Figs. 12,24, 58,71)

Pseudomyrma peperi Forel 1913:213  . Syntype workers, Patulul , Guatemala (Peper) ( MHNG) [Examined].  One syntype here designated LECOTYPE  .

Pseudomyrma spinicola race convarians Forel 1913:214  . Syntype worker, Patulul , Guatemala (Peper) ( MHNG) [Examined] [Synonymy by Ward 1989:452]  ,

Pseudomyrma sabanica  [sic] var. saffordi Enzmann 1945:89  . Syntype workers, Yerba Santa , Chiapas, Mexico ( G. N. Collins) ( MCZC) [Examined]  One syntype here designated LECTOTYPE. [Synonymy by Ward 1989:452], Pseudomyrmex peperi (Forel)  ; Kempf 1972:222  .

Worker measurements (n = 53). - HL 0.86-1.13, HW 0.76-0.90, MFC 0.034-0.064, Cl 0.76-0.89, REL 0.45-0.50, REL2 0.54-0.62, OOI 1.15-2.06, VI 0.59-0.79, FCI 0.042-0.071, SI 0.44-0.49, SI2 0.76-0.88, NI 0.62-0.71, PLI 0.54-0.65, PWI 0.63- 0.75, PPWI 1.41-1.83.

Worker diagnosis. - Small species ( HW <0.92) with moderately elongate head (Fig. 12); anterior margin of median clypeal lobe straight or slightly produced medially, laterally rounded or subangulate (never sharply angulate as in P. spinicola  and P. satanicus  ). Palp formula 4,3, rarely 5p4,3. Frontal carinae separated by about basal scape width. Mesosomal and petiolar profile typically as in Fig. 24, but in some workers basal and declivitous faces of propodeum less well differentiated and/or anteroventral tooth of petiole more prominent. Petiole and postpetiole broad, the former subtriangular in dorsal view with well developed posterolateral angles (Fig. 24). Dorsum of head obscurely punctulate-coriarious, matte. Remainder of body with finely punctulate to punctulate-coriarious sculpture, opaque to sublucid; propodeum lacking overlying rugulo-punctate sculpture seen in P. ferrugineus  . Standing pilosity not especially abundant, sometimes lacking (worn?) on mesonotum. Appressed pubescence abundant but very fine. Light to medium brown, rarely dark brown, the gaster sometimes darker than the rest of body; appendages lighter.

Comments. - P. peperi  is recognized by the features mentioned above and in the key. The combination of small elongate head, broad posterolaterally angulate petiole, and matte head surface is found in no other acacia ant workers or queens.

Distribution and biology. - This species has a rather wide distribution, from eastern Mexico to Nicaragua (Fig. 71). It has been collected from Acacia chiapensis, A. collinsii, View Cited Treatment View Cited Treatment   A. cornigera, View Cited Treatment   A. gentlei View Cited Treatment   , A. globulifera View Cited Treatment   and A. hindsii View Cited Treatment   . P. peperi  is apparently polygynous over much of its range, and often occurs sympatrically with the commoner P. ferrugineus  . Some aspects of its biology in Mexico are discussed by Janzen (1967b) under the name " P. nigrocincta  ".
