Measurements. total length: 16.6–18.1; head length: 2.1–2.3; head width: 3.3–3.4; pronotal width: 10.0–10.6; abdominal width: 9.0–9.9; length of antennal segments. I: 0.8–1.1; II: 1.9–2.2; III: 1.3–1.7; IV: 4.8–5.3; V: 5.6–5.8; interocular distance: 1.4–1.6 scutellum length: 8.1–8.7; scutellum width: 5.7–6.1; pronotal length: 3.4–3.8.

Diagnosis. Anterolateral margin of pronotum with complete solid black stripe. Cicatrices with dark brown punctures delimiting anterior sulci ( Fig. 18K ). Anterolateral margin not punctured. Male ( Fig. 6 A–C). Pygophore with dorsal rim shallowly excavated ( Fig. 6A ). Superior process of genital cup elliptic, well-developed, adjacent to dorsal rim ( Fig. 6B ). Paramere flat and rounded with single, black, digitiform, laterally slanting, distal projection ( Fig. 6A,B ); medially with longitudinal carina reaching distal projection. Proctiger with laterodorsal tufts of setae separated by tumid narrow ridge; posterior face rounded, medially convex, with lateral tumescence ( Fig. 6B,C ). Ventral rim central excavation in “V” shape; expansion well-developed, flat, apically rounded, ventrally curved and surpassing level of posterolateral angles in ventral view ( Fig. 6B,C ). Female ( Fig. 6D ). Gonocoxites 8 with posterior margin sinuous; inner angle acuminate and projected over gonocoxites 9 almost touching each other; sutural border with elliptic, median excavation. Gonapophyses 8 exposed.

Comments. Breddin (1907) considered Edessa necopinata similar to E. quadridens because of the form of the head and pronotum, and color of the body. Comparing the genitalia of both species, there are clear differences in posterior margin and sutural border of gonocoxites 8 ( Fig. 6D and 1D ), shape of the paramere ( Fig. 6B and 1B ) and expansion of ventral rim ( Fig. 6C and 1C ). The female is described here for the first time. Females of H. necopinatus , H. boerneri and H. offuscatus are very similar due to elliptic excavation of sutural border. In H. necopinatus ( Fig. 6D ) inner angle of gonocoxites 8 is slender and more developed than in H. offuscatus ( Fig. 7D ) and H. boerneri ( Fig. 2D ).

Distribution ( Fig. 21 ). ECUADOR: Sucumbios, Orellana, Pastaza.
