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. 16 A–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. tragelaphus to E. nigrispina . When analyzing the general external morphology, H. tragelaphus has humeral angles of pronotum well developed, globose and slightly posteriorly directed ( Fig. 20G ), while E. nigrispina has apex acute and strongly curved posteriorly. The shape of the humeral angles also distinguishes this species from the others of the group H. oxyacanthus .

Distribution ( Fig. 23 ). PERU: Loreto.
