2. Posterior margin of tergites delineated with dark brown (Figs. 3A, 4A, 7A, 8A, 11A, 12A, 15 AB). Tympanum absent on both sides of fore tibia. Ovipositor without denticulations (Figs. 4F, 12G). Mexicanum Group ............................ 3
- Posterior margin of tergites not delineated in dark brown; or if delineated, then with light brown or dark ocher. Tympanum present on fore tibia. Female ovipositor with dorso-posterior edge denticulate (female of G. dilutum unknown). Karnyi Group .. ................................................................................................... 6
3. Small to larger sized (18–30 mm.). First two abdominal tergites with stridulation pegs equidistant grouped, these pegs small (Figs. 3D, 7D, 8D).................................................................................... 4
- Mid to larger sized (22–30 mm.). First two abdominal tergites with stridulation pegs smaller than the pegs of the other species, very densely spaced (Figs. 11D, 12D)..................................................................... 5
4. Male paraproct with two sections: a basal section, which is fleshy and thick, and a distal section that is thin and flexible, and armed with a dorsal spinule on lateral mid-margin (Fig. 4I).......................................... G. mexicanum
- Male paraproct cylindrical, curving upwards from half its length, moderately dilated and with a rounded apex devoid of spinula (Fig. 7I)........................................................................... G. brevivaginalis n. sp.
5. Male paraproct almost finger-like, with a very small and almost apical sclerotized spinule.................. G. tamaulipas
- Male paraproct cylindrical, elongated, curving upwards from the base, with a rounded apex without spinula, and with a membranous fold (Fig. 11I).................................................................... G. huasteca n. sp.
6. Coloration ocher, posterior border of tergites delineated with ocher slightly darker than rest of body; last tergite hooks of males clearly thicker and somewhat shorter; male paraproctal processes with or without denticles; ovipositor with dorso-posterior border denticulate..................................................................................... 7
- Coloration uniformly light yellow; last tergite hooks of males almost spine like; male paraproctal processes finger-like without denticles, spines or hooks (female unknown)......................................................... G. dilutum
7. Male paraproctal process with a dorso-apical hook-like spine; male subgenital plate without any posteromedian notch; ovipositor with distinctly less numerous denticles on dorsal edge............................................... G. karnyi
- Male paraproctal process without spines or denticles; male subgenital plate with a v-shaped posteromedian notch; ovipositor with more denticles on dorsal edge.............................................................. G. dentatum
8. Male paraproct quadrangular, expanded from its base or at least the medial region. Magnaproctalis Group ............. 9
- Male paraproctal process not expanded, preserving its shape from base to apex, generally cylindrical and with diverse amount of curvature. Gracile Group ........................................................................... 10
9. Dorsal surface of the body, colored in solid dark brown, and with dorsal white spot at hind femur apex, also seen in distal section of all tibiae and tarsi (Fig. 17A). Ninth tergite not divided on the postero-medial margin, subgenital plate with posteromedian notch V-shaped...................................................................... G. stephanosoltis
- Dorsal surface of the body, colored in brown and without white spots. Ninth tergite divided on the postero-medial margin, subgenital plate without a deep posteromedian notch........................................... G. magnaproctalis
