( Figs. 1B View Figure 1 , 2A View Figure 2 )

Material examined. Brazil, state of Maranhão, Paulino Neves municipality, São José stream (02°49’26.2”S 42°32’38.3”W), 20.X.2014, 6 males (22.98‒30.59 mm CW and 19.51‒27.08mm CL) (CDZ 618) GoogleMaps .

Distribution. Brazil ( Magalhães and Turkay, 1996b; Barros and Pimentel, 2001; Magalhães, 2003a; Lima et al., 2013).

Remarks. Three of the six specimens showed an asymmetric carapace in relation with the number of teeth. Two specimens showed six teeth on the right margin and five teeth on the left margin of the carapace, while one showed five teeth on the right margin and six on the left. According to Magalhães (2003a), this species presents variations on the carapace margin, having thin sharp teeth, which may be blunt or faded in larger specimens. The teeth of the carapace in the specimens found in this study can be considered thin, sharp and smaller in relations with those recorded by Lima Júnior et al. (2008) in Piauí. On the other hand, the teeth of individuals studied by Freita et al. (2013) in Pernambuco’s semi-arid region, can be considered as blunt or faded.
