Centruroides tecomanus is another species that could be confused with the new species herein described (Figs. 6 and 7),owing to its general appearance; however, in addition to the morphometric differences (Tables 3 and 4), the coastal distribution of this species; the constant color pattern of its carapace,always with 4 thin and well defined dark lines (Fig. 6.1, 6.5);and the subaculear tubercle well developed and generally with its point oriented toward the point of aculeus (Ponce-Saavedra et al.,2009) (Fig. 6.21, 6.25) are enough to distinguish this species from the newly described one.
