Measurements. total length: 15.8–18.2; head length: 2.0–2.2; head width: 3.1–3.4; pronotal width: 10.0–11.3; abdominal width: 8.8–10.0; length of antennal segments. I: 0.7–1.0; II: 1.6–2.0; III: 1.2–1.6; IV: 4.0–5.2; V: 4.4–5.2; interocular distance: 1.4–1.6; scutellum length: 7.3–9.2; scutellum width: 5.5–6.3; pronotal length: 3.2–3.8.

Diagnosis. Anterolateral margin of pronotum yellow without solid black stripe. Cicatrices with dark brown punctures delimiting anterior sulci ( Fig. 18IView FIGURE 18). Anterolateral margin with some brown punctures. Male ( Fig. 5View FIGURE 5 A–C). Pygophore with dorsal rim widely excavated ( Fig. 5AView FIGURE 5). Superior process of genital cup short, half-moon shaped; next to dorsal rim ( Fig. 5BView FIGURE 5). Paramere with a single lobe curved anteriorly, tapering and elongated, margin rounded; stalk cylindrical with a small carina on inner side continuing along anterior lobe ( Fig. 5BView FIGURE 5). Proctiger with laterodorsal tufts of setae separated by wide ridge; posterior face ogival ( Fig. 5B,CView FIGURE 5). Ventral rim with expansions rounded, slightly tumid, short, almost level with posterolateral angles in ventral view ( Fig. 5CView FIGURE 5); base of each expansion with a conspicuous transverse carina ( Fig. 5A,BView FIGURE 5). Female ( Fig. 5DView FIGURE 5). Gonocoxites 8 posterior margin sinuous, slanting, inner angle rounded; sutural border divergent from basal third, gonapophyses 8 slightly exposed.

Comments. The male is described here for the first time. Breddin (1907) considered Edessa eburatula  closely related to E. jugalis  , which is synonymized with H. quadriden  s here. Actually, Hypoxys eburatulus  is closely related to H. dolosus  . Both species can be separated by expansions of ventral rim smaller in H. eburatulus  ( Fig. 5CView FIGURE 5) than in H. dolosus  ( Fig. 4CView FIGURE 4). Superior process of the genital cup is very similar in the photos presented here, but in H. eburatulus  ventral part of the process is as long as dorsal part ( Fig. 5BView FIGURE 5); in H. dolosus  ventral part is much longer than dorsal one (hidden by paramere in Fig. 4BView FIGURE 4), dorsal part looks more a transverse crest as described above. Paramere is also very similar, but in H. dolosus  the developed inner carina gives a triangular shape to the head of paramere ( Fig. 4BView FIGURE 4), while in H. eburatulus  the tiny carina does not interfere and the head looks convex ( Fig. 5BView FIGURE 5). Genital plates are very similar and do not show reliable characters. The distribution is the best way to separate both species because H. eburatulus  is the only species of the genus found in Central America ( Fig. 21View FIGURE 21).
