Most of the morphological structures of the new Mexican species are similar to this South American species. These features include the ocular plates, as well as the ornamentation on plates and leg telofemur. Notable differences include the setae which lie outside the ocular plate in <i>S. cramerae</i>, and on it in <i>S. similis</i>. Likewise, ds­3 is located on the AD plate in <i>S. cramerae,</i> and outside of this plate in <i>S. similis</i>. P2 of the new species has a ventral bristle similar to that of <i>S. similis</i> and <i>S. areolatus</i> from Chile, but without being borne on a knob (the ventral apophysis). The setal pattern of the Mexican species is shared with <i>S. areolatus</i>, but the ornamentation of the latter is quite distinctive, differing from that of <i>S. cramerae</i> with the P2.</p> <p> Newell (1984) designated six species (<i>S. obtusus, S. subobtusus, S. areolatus, S. magellanicus, S. hulingsi</i>, and <i>S. pectinatus</i>) from South America as “group 1” based on a shared suite of features. The Mexican species described here shares several of these characters, specially with <i>S. hulingsi</i>, in which only the location of ds­2, the number of the minute teeth on claw processes, the size of the idiosoma, and the form of the anterior margin of PD are different. The ornamentation with foveae on the telofemur of <i>S. cramerae</i> is very similar to that of <i>S. coreensis</i> Chatterjee & Young Chang, 2004 from Korea. However, the two species differ in the position of ds­2, the width of AD and PD, and the number of minute teeth on the claw processes.</p> <p> Also <i>S. cramerae</i> <b>sp. nov.</b> is closely with <i>S. fuscus</i> Viets and <i>S. euphractus</i> Pepato & Gonçalvez­Tiago, both cited from American Atlantic. These three species have the ds­2 outside of OC and similar ornamentation of dorsal plates, however <i>S. fuscus</i> and <i>S. euphractus</i> have a knob (ventral apophysis) on P2, which <i>S. cramerae</i> does not have. <i>S. euphractus</i> has two ventral setae on tarsus IV and <i>S. cramerae</i> only has one; <i>S. fuscus</i> has OC rounded in the terminal portion and in <i>S. cramerae</i> it is pointed, the tibia and tarsus are narrower in <i>S</i>. <i>fuscus</i> than in <i>S. cramerae</i>, and the number of minute teeth of claws in <i>S cramerae</i> (6–8) is smaller than in <i>S. fuscus</i> (10–14).</p>Published as part of <i>Rivas, Gerardo, 2006, First record of Simognathus (Acari: Halacaridae) from Mexico, including the description of a new species, pp. 61-68 in Zootaxa 1259</i> on pages 62-66, DOI: <a href="http://zenodo.org/record/173153">10.5281/zenodo.173153</a>
