( Figs. 11 , 46 , 69 )

Tetragonoschema darlingtoni Théry, 1944: 14 . Type locality: Colombia, Prov. Magdalena, Rio Frio.

Tetragonoschema darlingtoni: Bellamy, 2008: 1519 (catalogue).

Type specimen studied. Number of syntypes unknown; lectotype ( Fig. 11 ), here designated (male, MNHN): “ Colombia, Rio Frio, Mgd.[Magdalena Prov.], Darlington [p] // Darlingtoni Théry [h] Type [p] ” ; paralectotypes, here designated: “ Colombia, Rio Frio , Mgd.[Magdalena Prov.], Darlington [p] // Darlingtoni Théry [h] Type [p] ” (1 male, MFCB; 2 females, MNHN; 1 male, NMPC).

Further specimens studied. COLOMBIA. no precise data (2 males, MNHN) ; VENEZUELA. LARA: Barquisimento/ NW (10km S Bobare), 10º06ʹ51ʺN 69º26ʹ43ʺW, 690m, 11.x.2005, M. Hornburg leg. (1 male, 1 female, MHCB)

Diagnosis. Small, length: 3.4–4.8 mm, bronze with a red-violet tinge; pronotum with a well-developed prehumeral keel (like in Fig. 61 ); frons with very short, nearly indistinct, white pubescence; elytra flat with deep, wide impressions, 1.30 times as long as wide; aedeagus rather long, parameres with preapical spines ( Fig. 69 ).

Since the number of syntypes is unknown I hereby designate the male from MNHN as the lectotype and specimens from MFCB (1 male), NMPC (1 male) and 2 females from MNHN as the paralectotypes of T. darlingtoni Théry, 1944 .

Bionomy. Unknown.

Sexual dimorphism. Female differs from male in its somewhat stouter body and more intense red lustre of the frons and ventral surface.

Distribution. Colombia, Venezuela (new country record).
