Measurements. total length: 14.8–19.8; head length: 2.0–3.1; head width: 2.9–3.8; pronotal width: 9.1–13.7; abdominal width: 7.8–10.9; length of antennal segments. I: 0.8–1.1; II: 1.6–2.3; III: 1.1–1.6; IV: 3.6–5.3; V: 3.8–5.9; interocular distance: 1.4–1.8; scutellum length: 6.9–9.1; scutellum width: 4.9–6.9; pronotal length: 3.2–4.2.

Diagnosis. Anterolateral margin of pronotum with incomplete solid black stripe ( Fig. 19KView FIGURE 19). Dark marks on posterior part of pronotum ( Fig. 19KView FIGURE 19) varying from small, elongated, lateral black spots (including posterolateral angles), to an incomplete or complete stripe; stripe usually smoky brown, rarely solid black. Connexivum uniformly green or with small median yellow spots, sometimes also brown spots on excavated areas. Anterolateral margin of pronotum punctured. Anterior margin of scutellum concolorous ( Fig. 19KView FIGURE 19). Dorsal surface of abdomen brown. Ventrally apex of pseudosutures with or without rounded dark spots ( Fig. 19LView FIGURE 19). Male ( Fig. 12View FIGURE 12 A–C). Pygophore with dorsal rim shallowly excavated, central part straight; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim ( Fig. 12A,BView FIGURE 12). Paramere with anterior lobe triangular, long, reaching base of proctiger; posterior lobe slightly developed and acuminate ( Fig. 12BView FIGURE 12). Proctiger with widely separated tufts of dense setae dorsally; posterior face rounded and flat ( Fig. 12BView FIGURE 12). Ventral rim with expansions well developed, barely tumid, and acuminated ( Fig. 12CView FIGURE 12). Female ( Fig. 12DView FIGURE 12). Gonocoxites 8 inner angle reaching base of gonocoxites 9. Laterotergites 9 narrow, clearly surpassing sclerite uniting laterotergites 8.

Comments. This species has a curious history. The complement of the description was published ahead of the original description of the species ( Breddin 1904a, 1904b, 14 June and 1 July, respectively). Breddin (1904b) compared E. oxyacantha  to E. nigrispina  and E. melacantha  ; and Breddin (1904a) compared E. oxyacantha  to E. pachyacantha  . Hypoxys oxyacanthus  can be differentiated from E. nigrispina  and E. melacantha  by the humeral angles shorter and laterally directed (longer and curved backwards in E. nigrispina  and E. melacantha  ), and corium variegated (unicolorous in E. nigrispina  and E. melacantha  ). Here, the specie E. pachyacantha  is considered a junior synonym of H. tragelaphus  . Hypoxys oxyacanthus  can be separated from H. tragelaphus  by the humeral angles longer and rounded in H. tragelaphus  ( Fig. 19KView FIGURE 19 and 20GView FIGURE 20). Moreover, males of H. tragelaphus  presents projections of parameres more developed than H. oxyacanthus  ( Fig. 16BView FIGURE 16 and 12BView FIGURE 12). Hypoxys oxyacanthus  is closely related to H. leptacanthus  and H. tragelaphus  by sharing a projection of the dorsal rim that extends beyond posterolateral angles ( Figs. 12AView FIGURE 12, 15AView FIGURE 15, 16AView FIGURE 16). This species shows a strong variation among specimens in characters usually not variable, but male and female genitalia do not support the split of the species. A future molecular analysis may help to elucidate if Hypoxys oxyacanthus  is a complex of species or only a species with strong variation in a few characters.
