Tetragonoschema purpurascens Kerremans, 1897: 15. Type locality: Brazil, Pernambuco, Serra de Commuuaty, Aquas Bellas.
Tetragonoschema purpurascens: Kerremans, 1903: 169 (catalogue); Bruch, 1911: 231 (catalogue); Kerremans, 1913: 582 (note); Obenberger, 1922: 70 (revision, key); 1930: 559 (catalogue); Blackwelder, 1944: 315 (catalogue); Théry, 1944: 20 (revision, key, redescription); Bellamy, 2008: 1520 (catalogue).
Tetragonoschema latum Théry, 1944: 18, syn. nov. Type locality: Paraguay
Tetragonoschema latum: Bellamy, 2008: 1519 (catalogue).
Tetragonoschema missionarium Obenberger, 1947: 6, syn. nov. Type locatity: Argentina, Missiones, Concepción, Santa María.
Tetragonoschema missionarium: Bellamy, 2003: 135, fig. 344 (illustrated catalogue); 2008: 1520 (catalogue).
Type specimens studied. T. purpurascens (number of syntypes unknown), lectotype (Fig. 21), here designated (female, MNHN): “[Brasil] Aquas Bellas, Pernambuco [p] // purpurascens Kerr. Type [h] // Tetragonoschema purpurascens n. sp. [h] Kerremans det. [p] // Muséum Paris Coll. E. Gounelle 1915 [p]”; T. latum, holotype (Fig. 22) by monotypy (female, MNHN): “ Paraguay [h] // collection v. d. Pool [p] // lata Théry [h] Type [p] // Muséum Paris 1935 coll. A. Théry [p]”; T. missionarium (number of syntypes unknown), lectotype (Fig. 23), here designated (female, NMPC): “Misiones-Argentina, Dep.[artamento] Concep.[ción] Sta María, M. J. Viana [p] // Typus [p, red] // Tetragonoschema missionarium m. Type [h] Det. D r. Obenberger [p] // Mus. Nat. Pragae Inv. [p] 22839 [h]”.
Further specimens studied. ARGENTINA. SANTIAGO DEL ESTERO: Chaco, Resistencia, 18.x.1936, Denier leg. (1 male, MNCN); MISIONES: Loreto, xi.1962, M. Viana leg. (2 females, JEBC); Sta Maria, xi.1958, M. Viana leg. (1 female, JEBC); BRAZIL. GUANABARA: Botafogo, M. Alvarenga leg., ix.1970 (1 female, MNCN); PARAGUAY. SAN PEDRO: Juan Pedro Cororo, xii.1983 (1 male, NMPC); no precise data (1 female, ISNB).
Diagnosis. Entirely black, sometimes with a very slight red tinge, dorsal surface completely asetose; frons flat with shallow postclypeal impression; pronotum moderately convex with indistinct lateroposterior depressions, lateral margins slightly angulate; elytra 1.15–1.20 times as long as wide, lateral margins slightly emarginate, posterior margin obliquely truncate; aedeagus slender, subcylindrical (Fig. 71).
Length: 4.2–4.5 mm.
Since the number of syntypes of T. purpurascens is unknown I hereby designate the female from MNHN as the lectotype of T. purpurascens.
Since the number of syntypes of T. missionarium is also unknown I hereby designate the female from MNPC as the lectotype of T. missionarium.
Having studied the lectotype of Tetragonoschema purpurascens, holotype of T. (T.) latum and lectotype of T. (T.) missionarium I fail to find any difference and I conclude they are conspecific with T. (T.) purpurascens, T. (T.) latum Théry and T. (T.) missionarium being junior synonyms of T. (T.) purpurascens.
The holotype of T. (T.) latum and the lectotype of T. (T.) missionarium are merely large females of T. (T.) purpurascens.
Bionomy. Unknown.
Sexual dimorphism. The female differs from male only in its black ventral surface (black with a red lustre in male).
Distribution. Argentina, Brazil, Paraguay.
