FIGURE 6. Vectorized drawings created based on figures from Ávila-Pires (1995) and Kohler et al. (2012), and on a specimen photograph from Torres-Carvajal & Lobos (2014), showing the use of different names in literature for a same scale character. (A) Alopoglossus viridiceps: enlarged scales (Torres-Carvajal & Lobos 2014: 114); (B) Loxopholis snethlageae: fourth pair of chinshields (Ávila-Pires 1995: 412); (C) Alopoglossus buckleyi: pregulars (Ávila-Pires 1995: 321); (D) Loxopholis percarinatum: fourth pair of chin shields (Ávila-Pires 1995: 404); (E) Alopoglossus copii: tiny scales (Kohler et al. 2012: 183). For a standardization of the nomenclature of scale characters, as suggested here: red, fourth pair of chin shields; blue, pregular scales.
