( Figs. 12 View FIGURES 10 – 18 , 47 View FIGURES 46 – 54 , 79 View FIGURES 72 – 81 )

Tetragonoschema fossicollis Kerremans, 1900: 297 . Type locality: Brazil, Prov. Goyaz, Jatahy.

Tetragonoschema fossicollis: Kerremans, 1903: 168 (catalogue); Obenberger, 1922: 72 ( fossicolle View in CoL , key); 1930: 559 ( fossicolle View in CoL , catalogue); Blackwelder, 1944: 315 (checklist); Théry, 1944: 16 (catalogue).

Tetragonoschema pujoli Théry, 1944: 20 View in CoL , syn. nov.. Type locality: Brazil. Prov. Goyaz, Jatahy.

Tetragonoschema pujoli: Bellamy, 2008: 1520 View in CoL (catalogue).

Type specimens studied. T. fossicolle (number of syntypes unknown), lectotype ( Fig. 12 View FIGURES 10 – 18 ), here designated (male, BMNH): “ Holotype [p, rounded, red-framed] // [ Brazil, Prov. Goyaz] Jatahy, Donckier [h] // Kerremans 1903 –59 [p] // fossicollis Kerr. Type [h]” ; T. pujoli , holotype ( Fig. 13 View FIGURES 10 – 18 ) by monotypy ( female, MNHN): “Museum Paris, Bresil [p], Prov.[ince] de Goyaz, Jatahy, 1903, H. Donckier [h] // Jatahy, Goyaz [p] // Pujoli Théry [h] Type [p]”.

Further specimens studied. BRAZIL. GOYAS: Jatahy ( 1 male, ISNB).

Diagnosis. Very small, length: 3.1–3.5 mm, short, black with red humeral patches; elytra nearly as long as wide, 1.10 times as long as wide; antennae very short, barely reaching anterior third of lateral pronotal margins when laid alongside the pronotum; anterior pronotal margin with large medial lobe; male metatibiae slightly curved and enlarged posteriorly; aedeagus almost spindle-shaped, parameres without preapical spines ( Fig. 79 View FIGURES 72 – 81 ).

Since the number of syntypes of T. fossicolle is unknown I hereby designate the male from BMNH as the lectotype of Tetragonoschema fossicollis .

After having studied the lectotype of T. ( T.) fossicolle and holotype of T. ( T.) pujoli I have failed to find any substantial differences and I conclude that they are conspecific, T. ( T.) pujoli being a younger synonym of T. ( T.) fossicolle .

Bionomy. Unknown.

Sexual dimorphism. No difference between male and female was observed except for the slightly curved and enlarged male metatibiae.

Distribution. Brazil (prov. Goyaz).

Note. According to the description ( Kerremans, 1900) the pronotum bears a small, rounded, medial depression. After having studied Kerremans syntype (hereby designated as the lectotype) I found that the depression is somewhat eccentric and irregular and most probably it is a secondary injury. Thery´s holotype of T. pujoli ( Fig. 13 View FIGURES 10 – 18 ) has no sign of any pronotal depression.
