Cyphomyrmex auritus: Emery, 1922 (nec Mayr, 1887), pl. 7, fins. 13, 13b (Female: head and fore winjj). Types. - Holotype worker from Nova Teutonia, Santa Catarina State, Brazil (Plaumann) Oct. 1955; 3 paratypes workers likewise from southeastern Brazil: Rio Grande do Sul State, Barros Cassal, Sept. 1960 (F. Plaumann) 1 worker; Erechim, July 1960 (F. Plaumann) 1 worker; Parana State: Rio Azul, 1000 m, October 1959 (F. Plaumann) 1 worker. All in this author's collection (WWK). Worker. - Total length 3.2-3.4 mm; head length 0.82- 0.91 mm; head width 0.69-0.79 mm; thorax length 0.98-1.07 mm; hind femur length 0.72-0.83 mm. Fuscous brown; opaque. Rather close to strigatus, with the following diagnostic characters: 1) Postero-median portion of clypeus of peculiar shape, with the teeth close together, and prominently overhanging the vertical and slightly excavate anterior portion of clypeus (Fig. 4). 2) Frontal carinae scarcely expanded in front, scarcely rounded, little constricted behind. 3) Preocular carina reaching back to occipital corner as a well-developed, slightly raised carinule, never just vestigial behind eyes. 4) Femora and tibiae prismatic, hind femora broadened beneath ab basal third, with a prominent foliaceous lamfnule projecting from the posterior border which, in side view, forms a distinct angle. Apical half of tibial borders distinctly marginate. 5) Postpetiole scarcely elevated in front, without an anterior vertical face; conspicuously transverse and never longer than petiolar node (Fig. 17). 6) Appressed pilosity fine, minute and inconspicuous, never scale-like. Distribution. - Known only from the four stray type workers, this species is apparently confined to southeastern Brazil. Note. - Fig. 4 (head) is based upon the holotype specimen, Figs. 17 and 27 were drawn from the Barros-Cassal paratype.Published as part of Kempf, W.

Yellowish-brown; cheeks and occiput rather ferruginous. Integument opaque; head, postpetiole and gaster sharply, rest of body more finely reticulate-punctate. Pubescence scarce and appressed. Erect hairs absent. Head (fig. 4) longer than broad; sides scarcely convex; occipital corners, not considering the three prominent and subacute teeth, rather broadly rounded. Mandibles striolate, with 6 teeth on chewing border. Anterior margin of clypeus convex, notched in the middle. Frontal area impressed. Frontal carinae convex and covering the antennal socket, prolonged caudad as a pair of prominent ridges, which bifurcate in the rear before reaching occiput; inner branches more approximated to each other, sharp, strongly raised, terminating as a prominent tooth on occiput; outer branches weaker, obliquely running caudad, fading out before reaching the occipital corner. Occiput between mesial teeth excised. Carinule of cheeks distinct, curving mesad posteriorly and fading out at level of eyes. Thorax (fig. 5) rather slender and elongate; promesonotum in profile convex; impressed at mesoepinotal junction. Pronotum with 3 pairs of spines, one spine anteroventrally at each side, 4 spines dorsally arranged in a transverse row. Mesonotum with 3 pairs of spines, disposed in two longitudinal rows, gradually diminishing in size to the rear. Basal face of epinotum anteriorly with a pair of short, posteriorly with a pair of long, acute, rather elevated spines. Sides of epinotum with a distinct tooth above and somewhat in front of the spiracle. Petiole (fig. 6) longer than broad, its dorsum posteriorly with a pair of obliquely raised short spines. Postpetiole scarcely longer than broad, subtrapezoidal in dorsal aspect, dorsally strongly flattened with a pair of spinelike tuberosities near the anterior border; posterior border emarginate in the middle; circular pit rather vestigial. Gaster anterolaterally marginate. The paratypes agree with the holotype in all essential features of structure and livery. Their measurements have already been given in the description of the holotype. Types - 4 workers. Brazil, Sao Paulo State: Federal highway BR - 2. Sao Paulo - Curitiba, km 40, May 7, 1960 (W. W. Kempf) 2 workers (holotype and paratype); Rio de Janeiro State: Petr6polis, April 21, 1945 (W. W. Kempf) 1 worker (paratype); Santa Catarina State; Chapec6, December 1957 (F. Plaumann) 1 worker (paratype). All specimens in my collection (WWK). This species differs from parallelus as follows: Clypeus notched in the middle; longitudinal carinae of vertex sharper and more prominent; teeth and spines of occiput better developed, rather acute; occipital corners more rounded; mesonotum with an additional pair of spines; epinotal spines more elevated; petiole longer than broad; postpetiole not longer than broad, having anteriorly on dorsum a pair of prominent tubercles and posteriorly an ill-defined circular pit. All four specimens were taken as strays from forest floor cover. This may mean another distinctive trait, since parallelus is a denizen of open areas.Published as part of Kempf, W.

Scapes of antennae as long as head capsule, greatly surpassing occipital corner. All funicular segments decidedly longer than broad. Thorax as shown in Fig. 8. Integument subopaque but sculpture indistinct. Hairs not arising from prominent tubercles. Pronotum with indistinct humeral angle, antero-inferior corner rounded, lateral teeth low, mesial teeth absent. Mesonotum with rather prominent anterior conical spines, facing obliquely laterad, followed by two pairs of small denticles, the posterior pair almost indistinct. Thorax constricted dorso-laterally at mesoepinotal junction, lacking a suture. Basal face of epinotum narrow, laterally indistinctly marginate; anteriorly indistinctly, posteriorly distinctly dentate; the latter representing the extremely short and inconspicuous epinotal spines. Epinotal stigma prominent. Femora thin, cylindrical, hind femora about as long as thorax. Petiole and postpetiole as shown in Figs. 8 and 9. Piligerous tubercles prominent. Petiole pedunculate, node proper twice as broad as peduncle. Postpetiole flattened above, with a deep postero-median excision. Gaster opaque, with minute piligerous tubercles rather evenly distributed. Tergite I antero-laterally vestigially marginate. Female and male unknown. Specimens examined: 22 workers, as follows: Brasil, Goias State, Anapolis, January 7, 1966, W. W. Kempf leg. 16 workers (holotype and paratypes, WWK n. 4230); same locality but different nest, January 4, 1966, W. W. Kempf leg. 4 workers (paratypes, WWK n. 4199); Sao Paulo State, Agudos, December 13, 1955, W. W. Kempf leg. 1 worker (paratype, WWK n. 1493); Mato Grosso State: Chapada, May 1959, C. Amann leg. 1 worker (WWK, paratype). Discussion. - Although highly distinctive, dichrous belongs to the species-group which is characterized by smooth mandibles, by a more or less defined antennal scrobe, by rather straight preocular carinae that do not curve mesad above eyes, by the lack of a basal lobe on antennae. This group comprises by far the greatest number of species in the genus. Within this group, dichrous may at once be recognized by the ensemble of the following characters: triangular frontal lobes, lack of paired carinae on vertex, lack of an inferior occipital spine or tooth, lack of midpronotal teeth, lack of conspicuous tubercles on thorax, postero-dorsal border of postpetiole deeply excised. In addition, dichrous has the antero-inferior angle of pronotum rounded, a character which is only found in isthmicus and another still undescribed but otherwise completely different species. T. isthmicus differs from dichrous in the shape of the frontal lobes, the completely margined antennal scrobe, the presence of midpronotal teeth, the quadricarinate tergum I of the gaster. The same characters, plus the dentate antero-inferior pronotal corner, separate oetkeri and urichi, the closest sympatric species, from dichrous. The present species, which was found in Anapolis near km 46 of the Goiania highway, in a scrub-covered xerophilus woodland ("cerrado") by the gravel road leading to Leopoldo Bulhoes, at an altitude over 1000 m. The single nest entrance was surrounded by a sizeable crater of loosely heaped up earth crumbs. The lone stray worker from Agudos was taken from the ground in open and rather dry parkland. Hence it is probable that this species is a typical denizen of the vast "campos", that characterize the vegetation of central Brazil.Published as part of Kempf, W.
