( Figs. 3 View FIGURES 1 – 9 , 72 View FIGURES 72 – 81 )

Tetragonoschema patagonicum Obenberger, 1922: 69 View in CoL . Type locality: Argentina, Patagonia, Santa Cruz.

Tetragonoschema patagonicum: Obenberger, 1930: 559 View in CoL (catalogue); Blackwelder, 1944: 315 ( patagonica, checklist); Théry, 1944: 20 (revision, key, redescription); Cobos, 1959: 13 (taxonomy); Bellamy, 2008: 1520 (catalogue).

Type specimen studied (number of syntypes unknown). Lectotype ( Fig. 3 View FIGURES 1 – 9 ), here designated (male, NMPC): “[ Argentina] Patagonia, Sta Cruz [h] [Departamento Santa Cruz] // Typus [p, red] // Tetragonoschema patagonicum m. Type [h] Det. D r. Obenberger [p] // Mus. Nat. Pragae Inv. [p] 22833 [h]”.

Diagnosis Rather convex, subparallel; pronotum and elytra with short, recumbent, white pubescence; aedeagus regularly spindle-shaped ( Fig. 78 View FIGURES 72 – 81 ); the rather unusual shape of pronotum ( Fig. 3 View FIGURES 1 – 9 ) and long frontal pubescence are the best characters distinguishing this species from other species of the subgenus Patagoschema.

Length: 4.6 mm.

Since the number of syntypes is unknown I hereby designate the male from NMPC as the lectotype of T. patagonicum Obenberger, 1922 .

Bionomy. Unknown.

Sexual dimorphism. Female unknown.

Distribution. Argentina—“Patagonia”, prov. Santa Cruz.

Note. The southernmost distributed species of the genus Tetragonoschema . The province of Santa Cruz is situated south of latitude 46 where the climatic conditions are rather extreme and T. ( P.) patagonicum is most probably one of the southernmost distributed species of the Neotropical Buprestids. Unfortunately no further specimen has been found in collections.
