Gutiérrez-Meza col.” ( 3♂ , 1♀ ). Same data, except: “ 27-VIII-2016 ” ( 1♀ ) . Previous Records ( Fig. 4 ). Rodríguez et al . (2018) included the same Mexican states that were cited by Chani-Posse (2006) , in addition to Hidalgo and Querétaro , but the source of the records for these two states is unknown, since in addition to citing Chani-Posse (2006) , Rodríguez et al . (2018) cited the work of Navarrete-Heredia et al . (2002) , in which C. mexicanus had not yet been described and all the records were given for C. flagrans . Therefore, from this reference ( Rodríguez et al . 2018 ), here we only take as valid the record that directly originates from the study area, which was Cerro García in the state of Jalisco .
