Stizocera geniculata ( Pascoe, 1866) 

( Figure 83View FIGURES 80–84. 80)

Sphaerion geniculatum Pascoe, 1866: 479  . Periboeum geniculatum  ; Lacordaire, 1868: 319; Gemminger, 1872: 2824 (cat.); Aurivillius, 1900: 409 (distr.). Stizocera geniculata  ; Gounelle, 1907: 242; Aurivillius, 1912: 99 (cat.); Blackwelder, 1946: 567 (checklist); Zajciw, 1962: 199; 1967: 304; Gilmour, 1968: 138; Martins & Napp, 1983: 80; Monné, 1993: 7 (cat.); Monné & Giesbert, 1994: 63 (checklist); Monné, 2005: 253 (cat.); Martins, 2005: 173; Bezark, 2013: 43 (distr.); Monné, 2018a: 367 (cat.).

This species was originally described from Brazil, without detailed place. Aurivillius (1900) reported the species from Venezuela, but it was Martins & Napp (1983) who first reported a state in Brazil (Rondônia). More recently, Martins (2005) recorded the species for Brazil (Roraima), and Bezark (2013) for Trinidad and Tobago.

In Martins & Napp (1983), S. geniculata  is only mentioned in the key to species of the genus, as being from Venezuela and Brazil (Rondônia). But, according to Martins (2005) (translated): “Our identification of S. geniculata  may not be exact, although the specimens agree with the original description, except in the coloration of the head and prothorax which, according to Pascoe (1866), are “castaneis” or “reddish chestnut.” Our specimens have the head and prothorax dark reddish.” It is true that the holotype has the head and prothorax reddish brown. However the specimens examined by us show that the color is variable, and may be light reddish-brown, dark reddish-brown or nearly dark brown. Also, the elytral apex is somewhat variable, as also occurs in several species of Elaphidiini  . According to Martins (2005), he examined two specimens from MZSP collection: “ BRAZIL. Roraima: Baixo Rio Mocajaí (sul de Boa Vista), 2 females, IV-V.1962, E. Dente col.” We have no doubt that both Martins & Napp (1983) and Martins (2005) based the Brazilian state record on the same specimens, and they are from the Brazilian state of Roraima. Thus, we are formally excluding S. geniculata  from the Brazilian state of Rondônia.
