Remarks: Pérez-Higareda, López-Luna & Smith (2002) revalidated concolor as a separate species, however, McCranie (2011, 2015) did not accept this arrangement and retained concolor as a synonym of lineatus, pending further studies, followed by Wallach, Williams & Boundy (2014). Although reported from Colombia by Pérez-Santos & Moreno (1988), presence in the country needs confirmation, according to the strongly critical review of this work by Cadle (1992), in which he points out the considerable amount of unverifiable information presented by these authors. Although reported also from Panama (Auth 1994), presence in the country is unconfirmed (Solís, Ibáñez & Jaramillo 1996). Although included for Jalisco by Cruz-Sáenz, Guerrero, Lazcano & Télles-López (2009), presence in the state is considered undocumented herein, following Cruz-Sáenz, Muñoz-Nolasco, Mata-Silva, Johnson, García-Padilla & Wilson (2017), who did not list the species for Jalisco. Not listed for Distrito Federal by Lemos-Espinal & Smith (2020). Not listed for Mexico State by Lemos-Espinal & Smith (2020).
Distribution: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico (Campeche, Chiapas, Distrito Federal, Mexico State, Oaxaca, Queretaro, Quintana Roo, Tabasco, Veracruz, Yucatan), Nicaragua.
