Examined. Gaedike mentioned more than one specimen but did not mentioned gender of lectotype . So, we are designating the male as Lectotype FIGURE 15. H. leptacanthus .

Oxapampa : ♂ ♀ Edessa leptacantha Breddin, 1904 , Comp.w. TYPE Fernandes, JAM 1999 ( RMNH ) . Measurements. total length: 15.4–17.1; head length: 1.7–2.0; head width: 2.8–3.1; pronotal width: 10.3–11.6; abdominal width: 7.8–9.1; length of antennal segments. I: 0.8–1.0; II: 1.6–1.9; III: 1.0–1.3; IV: 3.6–4.4; V: 4.2–4.7; interocular distance: 1.4–1.6; scutellum length: 7.0–8.0; scutellum width: 5.0–5.8; pronotal length: 3.1–3.6. Diagnosis. Pronotum with small, elongate, lateral black spots including posterolateral angles. Anterolateral margin of pronotum without solid black stripe and not punctured. Posterolateral angles developed, as long as interocular distance. Anterior margin of scutellum yellow ( Fig. 20E ). Dorsal surface of abdomen brown. Connexivum green without spots, except distal margin of segment VII, dorsally urotergite 8 with inner black stripes continuing in free part of laterotergites 8 ( Fig. 20E ). Ventrally apex of pseudosutures without rounded dark spots ( Fig. 20F ). Male ( Fig. 15 A–C). Pygophore with dorsal rim barely excavated; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim ( Fig. 15A,B ). Paramere with anterior lobe strongly developed, almost reaching base of proctiger; posterior lobe strongly developed and acuminated ( Fig. 15B ). Proctiger with tufts of short setae widely separated, but not as much as in H. oxyacanthus . Ventral rim with expansions well developed, barely tumid, and rounded ( Fig. 15C ). Female ( Fig. 15D ). Gonocoxites 8 inner angle covering base of gonocoxites 9. Laterotergites 9 wide, lightly surpassing sclerite uniting laterotergites 8. Comments. Breddin (1904a) considered Edessa leptacantha related to E . pachyacantha (= H. tragelaphus ). These species can be differentiated by humeral angles globose in E . pachyacantha ( Fig. 20G ). Other characters are subtle: expansions of ventral rim are more rounded, setae of lateral excavation of proctiger shorter, and paramere has anterior and posterior lobes more developed in H. leptacanthus than in H. tragelaphus . The female of H. leptacanthus has four parallel narrow black stripes dorsally on seventh and eighth segments not found in H. tragelaphus . Distribution ( Fig. 23 ). PERU : Oxapampa.
