Measurements.total length: 17.5–18.3; head length: 2.2–2.3; head width: 3.3–3.4; pronotal width: 12.1–13.6; abdominal width: 9.0–9.7; length of antennal segments. I: 0.5–0.6; II: 1.1–2.3; III: 1.4–1.7; IV: 3.7–5.0; V: 3.6–5.0; interocular distance: 1.4–1.7; scutellum length: 7.6–8.8; scutellum width: 5.6–6.1; pronotal length: 3.6–4.2.
Diagnosis.Anterolateral margin of pronotum without solid black stripe, more concave than the other species, impunctate. Humeral angle with apex globose and solid black ( Fig. 20G). Connexivum with small green spots. Anterolateral margin more concave than the other species. Anterolateral margin not puncture. Scutellum with anterior margin concolorous ( Fig. 20G). Ventrally apex of pseudosutures without rounded dark spots ( Fig. 20H). Male ( Fig. 16A–C). Pygophore with dorsal rim shallowly concave; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim ( Fig. 16A,B). Paramere with anterior lobe shorter than posterior lobe; posterior lobe tongue-like. Proctiger with tufts of setae narrowly separated dorsally; posterior face subrectangular ( Fig. 16B). Ventral rim with expansion little developed, barely tumid, and acuminate ( Fig. 16C). Female ( Fig. 16D). Gonocoxites 8 inner angle reaching middle of gonocoxites 9. Laterotergites 9 narrow, clearly surpassing sclerite uniting laterotergites 8.
Comments. Breddin (1903)related E. tragelaphusto E. nigrispina. When analyzing the general external morphology, H. tragelaphushas humeral angles of pronotum well developed, globose and slightly posteriorly directed ( Fig. 20G), while E. nigrispinahas apex acute and strongly curved posteriorly. The shape of the humeral angles also distinguishes this species from the others of the group H. oxyacanthus.
