Glyphoderus centralis Burmeister, 1873:407 .

Diagnosis. Males. This species is separated from other Glyphoderus species by the shape and placement of the pronotal horns and tubercles ( Fig. 3 ). Glyphoderus centralis has the pronotum with two transversally elongated tubercles on apical half and two horns in middle; horns and tubercles on margin of central depression; anteromedial horn with ‘‘arms’’ robust, with medial anterior notch. No morphological characters were found to diagnose females of this species, females can be identified only by association with males.

Distribution ( Fig. 6 ). ARGENTINA: Chaco: Taco Pozo (1); Salta: Chaco Occidental, Los Colorados (100 km NE) (1); San Luis: Talita (1). Santiago del

Estero: Beltrán (2); Choya (21); El Charro (13); Fernández (5); Río Salado (4); San Gregorio (4); Puna (15); no more data (13).

Temporal Distribution. January (3); February (11), March (14), April (1); October (21), November (2), December (17).

Remarks. Zunino et al. (1989) and Martínez (1956) recorded G. centralis from the Argentinean provinces of Catamarca, Córdoba, La Rioja, and Tucumán. Though I did not study specimens from these provinces I believe that they should be considered as part of the distributional range.
