Key to Glaphyrosoma   species

(Modified from Cadena-Castañeda & Monzón, 2017)

1. Color light brown or ocher, with or without dark brown stripes on the posterior margin of tergites...................... 2

- Color dark brown or black ( Figs. 18A View FIGURE 18 , 19A View FIGURE 19 , 21A View FIGURE 21 )........................................................... 8

2. Posterior margin of tergites delineated with dark brown ( Figs. 3A View FIGURE 3 , 4A, 7A View FIGURE 7 , 8A View FIGURE 8 , 11A View FIGURE 11 , 12A View FIGURE 12 , 15 View FIGURE 15 AB). Tympanum absent on both sides of fore tibia. Ovipositor without denticulations ( Figs. 4F, 12G View FIGURE 12 ). 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 View FIGURE 3 , 7D View FIGURE 7 , 8D View FIGURE 8 ).................................................................................... 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 View FIGURE 11 , 12D View FIGURE 12 )..................................................................... 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 View FIGURE 7 )........................................................................... 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 View FIGURE 11 ).................................................................... 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 View FIGURE 17 ). 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  

10. Fore tibia with tympana on both sides, male paraprocts mostly cylindrical. Upper valve of ovipositor, without depressed ventral margin............................................................................................. 11
