(Figs. 5, 6)  
 Type material. Holotype male from 2 da Privada de los Pinos, Cuernavaca, Morelos; muerta en piso; 20/XI/2020; Reinier Núñez coll. (CER), at CNIN.   
 Diagnosis. This species can be easily separated from C. nahua and C. yaqui by the emargination of the posterior border of the subgenital plate and the reticulation of the tegminas.   
 Etymology. We dedicate this species in honor to Dr. Esteban Gutiérrez, great friend, colleague, professor, and researcher of the Museo Nacional de Historia Natural de La Habana, Cuba. For his contribution to the knowledge of the cockroaches of America.   
 Description. Holotype male: Total length 29 mm; body length 22 mm. Color: Usually amber, pronotum without distinguishable pattern; brown-orange abdomen with whitish posterior edges. Head: 2.5 mm long, 2.5 mm wide; interocular distance 1 mm; distance between eyespots 1.1 mm; distance between antennae 1.3 mm (Fig. 5d). Pronotum: subtriangular, rounded in the anterior margin and basal angles, posterior margin slightly proJected. Wings: tegmen macropterous, 16 mm long, 7 mm wide, presence of a pseudo-reticulate veins pattern (Figs. 4d, 5a, 5b); hind wings of 15 mm long, anal area folded into a fan shape. Legs (Fig. 5e): femur I with spination type B2 (sensu Roth 2003) in the anteroventral margin, four subequal basal spines, 11 middle spinules and two apical spines; femur II and III with one appendicular spine; tarsomeres I-IV of the three legs with numerous spinules on the prolateral margin, pulvillus of about the size of the internal length in each tarsomere I-IV; tarsal claws simple and asymmetric; aureolum between the nails, of about 80% of the length of the tarsal claws. Abdomen: With brush type tergal glands in tergite I (Figs. 5g, 5h); supra-anal plate triangular, proJected posteriorly, asymmetric paraproctus; pincer-shaped (Fig. 5i); subgenital plate (hypandrium) slightly asymmetric, with similar and finger-like styles (Figs. 5j, 5k). Male genitalia (Figs. 5k, 56): L1 wide type with an inflection point (Fig. 6a); L2vm simple stick shape, L2d sickle shape (6b); L3 (genital hook) short and sclerosed (6c); R1 tapered (Fig. 6d); R2 curved (Fig. 6e); R3 laminate with multiple folds (6f).   
 Distribution. Known only to the type locality, colony Loma Bonita, Cuernavaca, Morelos, Mexico.   
 Note. Male holotype presents a teratology in the last basal spine, which makes the apex to have a bifid shape (Fig. 5f).
