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. 18I ). Anterolateral margin with some brown punctures. Male ( Fig. 5 A–C). Pygophore with dorsal rim widely excavated ( Fig. 5A ). Superior process of genital cup short, half-moon shaped; next to dorsal rim ( Fig. 5B ). 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. 5B ). Proctiger with laterodorsal tufts of setae separated by wide ridge; posterior face ogival ( Fig. 5B,C ). Ventral rim with expansions rounded, slightly tumid, short, almost level with posterolateral angles in ventral view ( Fig. 5C ); base of each expansion with a conspicuous transverse carina ( Fig. 5A,B ). Female ( Fig. 5D ). 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. 5C ) than in H. dolosus ( Fig. 4C ). 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. 5B ); in H. dolosus ventral part is much longer than dorsal one (hidden by paramere in Fig. 4B ), 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. 4B ), while in H. eburatulus the tiny carina does not interfere and the head looks convex ( Fig. 5B ). 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. 21 ).
