Edessa tragelaphus Breddin, 1903: 139  ; Bergroth, 1908: 179; Kirkaldy, 1909: 165 (catalog); Froeschner, 1981: 67.

Edessa pachyacantha Breddin, 1904a: 136  ; Bergroth, 1908: 179; Kirkaldy, 1909: 161 (catalog) syn. nov.

Lectotype female. Edessa tragelaphus  . Ecuador, Coca, leg. Haensch ( SDEI). Designated by Gaedike (1971: 101, by use of “ Holotypus ”). Examined. 

Lectotype male. Edessa pachyacantha  . Peru, Marcapata ( SDEI). Designated by Gaedike (1971: 94). Examined. Gaedike also indicated one paralectotype female from the same locality. 

Material examined. PERU. Loreto: 2♀ ♂ Confl. de Los Rios Zumun e Yahuasyaw, II–80, J. Becker leg., Edessa tragelaphus Breddin, 1903 Comp.  w. TYPE Fernandes, JAM 1999. Edessa pachyacantha Breddin, 1904 Comp.  w. TYPE Fernandes, JAM 1999 ( RMNH)  ; ♂ E. Le Moult. Iquitos April. S. Roque. Edessa pachyacantha Breddin, 1904 Comp.  w. TYPE. Fernandes, JAM 1999 ( RMNH)  ; ♀ 80km NE Iquitos, 1km from Amazon River on Rio Yana- mono, Explorama Lodge, 1–5–IX–1992, Castner, Skelley, et al. ( JEE) 

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. 20GView FIGURE 20). Connexivum with small green spots. Anterolateral margin more concave than the other species. Anterolateral margin not puncture. Scutellum with anterior margin concolorous ( Fig. 20GView FIGURE 20). Ventrally apex of pseudosutures without rounded dark spots ( Fig. 20HView FIGURE 20). Male ( Fig. 16View FIGURE 16 A–C). Pygophore with dorsal rim shallowly concave; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim ( Fig. 16A,BView FIGURE 16). Paramere with anterior lobe shorter than posterior lobe; posterior lobe tongue-like. Proctiger with tufts of setae narrowly separated dorsally; posterior face subrectangular ( Fig. 16BView FIGURE 16). Ventral rim with expansion little developed, barely tumid, and acuminate ( Fig. 16CView FIGURE 16). Female ( Fig. 16DView FIGURE 16). 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. 20GView FIGURE 20), 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. 23View FIGURE 23). PERU: Loreto.
