Available from the Global Ant Project website: http:// gap.entclub.org/taxonomists/Kempf/ index.html Description (worker) Head longer than wide. Sides of head subparallel, slightly wider anteriorly, broadly rounded into posterior border, which is more or less straight. Antennal insertions relatively close together, separated by no more than three times the apical scape width. Scape fails to reach vertexal border. In lateral view, promesonotum slightly convex, mesonotal margin weakly convex to almost straight. Metanotal groove very deep, well-marked. Propodeal spiracle circular, opened posteriorly. Petiole with peduncle and node well differentiated, the node with subparallel anterior and posterior faces, dorsum convex. Petiolar spiracle at base of node. Petiolar ventral process shaped as rounded, anteroventrally directed tooth. Postpetiole subcampaniform, with a conspicuous transverse, ventral carina. Mandibles, most of promesonotum, dorsum of petiole and postpetiole, and gaster smooth and shining. Head with longitudinal, irregular rugulae mixed with dense foveae. Posterior portion of promesonotum with feeble, short rugulae. Most of mesopleura with irregular, short, longitudinal striae, mixed with fine reticulation. Most of propodeum and sides of petiole and postpetiole densely reticulated. Declivity of propodeum with several fine transverse carinae, the most posterior more marked. Moderately erect pilosity on head, promesonotum, petiole, postpetiole and gaster, little on propodeum. Scapes with several erect hairs. Longer hairs about 0.15 mm , those of head shorter. Body light brown to black, appendages lighter. Fig. 5. Distribution map for Kempfidris inusualis ( Fernández, 2007 ) comb. nov. Queen and male: Unknown.
