 Holotype male labeled: “ Chaco / Parque Nacional del Copo /25°58´21.7´´S; 61°57´31.6´´W. 21-XII-2010. F. C. Ocampo, F. Campón, B. Maldonado ” and with our red holotype label [IADIZA]. Allotype female labeled: “ Santiago del Estero. Santiago del Estero / Weisburd /22.IX.47” and with our red allotype label [MACN]. Paratypes labeled: “ La Rioja. RA. La Rioja 9 Km.

Santiago del Estero /Weisburd/22.IX.47” (4♂) [MACN]. Paratypes each with our yellow paratype label.   
 Description of Holotype. Length 14.7 mm; width 7.8 mm. Color light to dark reddish brown. Head: Frons mostly impunctate between eyes and coarsely rugopunctate just behind frontoclypeal carina. Frontoclypeal region with transverse carina slightly separated at middle (Fig. 4g). Clypeus strongly rugopunctate to transversely rugose, tapering to slightly emarginate, broad apex with 2 reflexed teeth. Mandibles with 2 teeth, apical tooth bluntly rounded, subapical notch shallow, broad (Fig. 6m –n); labium densely setose, paraglossa undeveloped, apex convergent (Fig. 7g); maxilla with galea developed and with 5 teeth (Fig. 5g). Pronotum: Surface moderately to moderately densely punctate; punctures large, umbilicate. Anterior margin lacking tubercle or fovea (Fig. 8g). Elytra: Surface with micropunctures and large punctures mixed; large punctures moderately dense, ocellate, and with 3 pairs of double rows. First broad interval with or without large punctures. Pygidium: Surface sparsely punctate, punctures becoming denser in basal angles; punctures small to moderate in size, weakly ocellate; in lateral view with convex surface. Legs: Protibia tridentate, basal tooth slightly removed. Protarsus in male simple, not enlarged. Mesotibia with relatively short transverse carinae ( Fig. 10m –n). Metatibia with 1 basal, transverse carina interrupted at middle (carina with spine-like setae) and 1 medial, transverse carina; apex truncate with about 29 spinules (Fig. 10n). Venter: Prosternal process tall, thick, apex small and suboval, usually with slender, long setae. Mesosternal surface sparsely setose, slightly concave at middle. Metasternal surface densely punctate, punctures ocellate, setose; setae slender and long. Male Genitalia: Parameres (Fig. 11g, 12g, 13g) narrowly subtriangular, apices curving outwards and, in caudal view, with small spinules near the apices of each paramere. Internal sac (Fig. 15g) lacking copulatory lamellae.   
 Allotype. Length 14.1 mm; width 7.6 mm. Similar to male, but pronotal surface on disc smooth; pygidial surface weakly convex. Gonocoxite smaller than gonocoxal sternite and lacking a semicircular furrow (Fig. 14g).   
 Paratypes. Males. Length 12.9–15.5 mm; width 6.0– 8.2 mm. The seven male paratypes do not differ significantly from the holotype.   
 Etymology. From the Latin spine, indicating a small process, and penis, in reference to the parameres. Used here to refer to the small spinules near the apices of the parameres (Fig 11g).
