description: Key to the species of Glaphyrosoma
1. Color light brown or ochre, with or without dark brown stripes on the posterior margin of tergites..................... 2
- Color dark brown or black............................................................................ .. 6
2. Posterior margin of tergites delineated with dark brown.......................................................3
- Posterior margin of tergites not delineated in dark brown, or if delineated with light brown or dark ochre................4
3. Male paraproctal process almost finger-like, not inflated in distal half but slightly widened near middle in profile.................................................................................................... G. tamaulipas
- Male paraproctal process distally narrowing to rather a rather large sclerotized tooth, which is acute-angled in ventral view............................................................................................. G. mexicanum
4. Coloration ochre, posterior border of tergites delineated with ochre slightly darker than rest of body; hooks of males last tergite clearly thicker and somewhat shorter; male paraproctal processes with or without denticles; female ovipositor with dorso-posterior border denticulate................................................................................5
- Coloration uniformly light yellow; hooks of males last tergite almost spine like; male paraproctal processes finger-like without denticles, spines or hooks; female unknown.......................................................... G. dilutum
5. Male paraproctal process longer and having 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 shorter and without spines or denticle; male subgenital plate with a V-shaped posteromedian notch; ovipositor with more denticles on dorsal edge...................................................... G. dentatum
6. Male paraproctal process notoriously expanded from its base or at least the medial region, quadrangular or lanceolate...... 7
- Male paraproctal process not expanded, preserving its shape from base to apex, generally cylindrical and with diverse amount of curvature......................................................................................... 9
7. Ninth tergite not divided in the postero-medial margin, paraproctal process dilated but not as much as in G. magnaproctalis and ovoid.............................................................................................. 8
- Ninth tergite divided in the postero-medial margin, paraproctal process much more prominent and rectangular.............................................................................................. G. magnaproctalis n. sp.
8. Ninth abdominal tergite in males with a pair of posterior lobes; tenth abdominal tergite strongly specialized with a pair of conical hooks near each other; each paraproct with large process moderately narrow in proximal half and strongly widened and inflated in distal half.......................................................................... G. bulbosum
- Ninth abdominal tergite in males with a longer and rounded posteromedian lobe directed partly downward and undivided; tenth abdominal segment normal; paraproctal processes with somewhat widened (ovoid) inflation in distal half, and with strong dorsal spine situated approximately in middle part of inflation and directed more or less upwards.......... G. anderi
9. Paraproctal processes not s-shaped....................................................................... 10
- Paraproctal processes s-shaped.................................................................... G. gracile
10. Paraproctal processes carved up and cylindrical............................................................. 11
- Paraproctal processes straight, thin and with sharp distal spine........................................... G. beretka
11. Body length medium (19 mm); ninth tergite moderately pronounced and with posteromedial margin smoothly undulated; tenth tergite narrow with pair of thick hooks that are curved upwards above medial portion of tergite; paraprocta constant in thickness from base to apex and curving upwards from middle of length into a hook, ending in a moderately sharp margin; subgenital plate rectangular, wider than long, thinning slightly towards apex, distally with pair of conical styles, shallow notch almost straight located between styli......................................................... G. hectorcentenoi n. sp.
- Body length large (27-34 mm); ninth tergite with posteromedial tergite pronounced and rounded; tenth tergite without being covered notoriously by ninth tergite, hooks thick and conical, producing outwards and slightly resting on ninth tergites prolongation; paraprocta sub cylindrical, curving sharply upwards close to apex without expanding, armed with sharp spine in internal area; subgenital plate slightly thinning from the base towards apex, apex armed on each side with cylindrical styli, notch “U” shaped and shallow........................................................... G. franciscoasturiasi n. sp.
