Key to species of Doesburgedessa

1. Humeral angles short and somewhat anteriorly directed (figs. 30–31). Anterior projection of metasternal process short (figs. 5–6, 11–12). Lobes of ventral rim of pygophore thin, not reaching the level of the posterolateral angles (figs. 2–3, 8–9). Angles of abdominal segment VII produced far beyond the level of the laterotergites 8 (figs. 4, 10) ...................................................................................................................................................................................... 2

- Humeral angles strongly developed and directed laterally (figs. 32–34). Anterior projection of metasternal process long (figs. 16–17, 22–23, 28–29). Lobes of ventral rim of pygophore thick, surpassing level of posterolateral angles (figs. 14–15, 19–20, 25–26). Angles of abdominal segment VII and laterotergites 8 less produced (figs. 21, 27) ..... 3

2. Jugae not punctured and not striped ahead of tylus. Apex of humeral angles light brown and not clearly posteriorly directed. Hemelytron with corial margin concolorous and punctures dark brown (fig. 30). Posterolateral angles of the pygophore developed. Paramere surpassing posterior limits of pygophore (fig. 1). Posterior margins of gonocoxites 8 concave, with a tiny tooth on posterolateral angle, contiguous with gonocoxites 9 (fig. 4) ............. D. rugifera

- Jugae punctured ahead of tylus, dark stripes covering punctures on margins of tylus and jugae. Apex of humeral angles dark and directed posteriorly. Hemelytron with corial margin black including punctures (fig. 31). Posterolateral angles of the pygophore strongly developed. Paramere enclosed by pygophore (fig. 7). Posterior margins of gonocoxites 8 convex and with a distinct tooth on posterolateral angle, detached from gonocoxites 9 (fig. 10) ......... ............................................................................................................................................................. D. nigrolimbata

3. Anterior part of metasternal process as long as wide at base (figs. 16–17). Posterior lobe of paramere long, almost reaching posterolateral angles of pygophore (figs. 13, 15) ............................................................................. D. armata

- Anterior part of metasternal process longer than wide at base (figs. 22–23, 28–29). Posterior lobe of paramere short (figs. 18–19, 24–25) ..................................................................................................................................................... 4

4. Posterolateral angles of pygophore truncate and straight. Paramere bent laterally (figs. 18–19). Lobes of ventral rim of pygophore small (fig. 20). Distal margin of gonocoxites 8 straight to slightly rounded. Laterotergites 9 short, not surpassing band uniting laterotergites 8 (fig. 21) ............................................................................................. D. linnei

- Posterolateral angles of pygophore developed and rounded. Paramere straight (figs. 24–25). Lobes of ventral rim large (fig. 26). Distal margin of gonocoxites 8 acuminate. Laterotergites 9 surpassing band uniting laterotergites 8, (fig. 27) .............................................................................................................................................. D. elongatispina
