Measurements. total length: 16.6–19.6; head length: 2.0–2.4; head width: 3.3–3.7; pronotal width: 10.1–11.8; abdominal width: 9.1–10.4; length of antennal segments. I: 0.9–1.1; II: 1.8–2.4; III: 1.2–1.8; IV: 3.4–5.7; V: 5.2–5.8; interocular distance: 1.3–1.7; scutellum length: 7.4–8.6; scutellum width: 5.6–6.6; pronotal length: 3.3–3.9.

Diagnosis. Anterolateral margin of pronotum with complete solid black stripe. Cicatrices with brown punctures delimiting anterior sulci ( Fig. 19C View FIGURE 19 ). Anterolateral margin with some brown punctures. Male ( Fig. 8 View FIGURE 8 A–C). Pygophore with dorsal rim sinuous, shallowly excavated ( Fig. 8A View FIGURE 8 ). Superior process of genital cup laminar with outer corner protruding; adjacent to dorsal rim ( Fig 8B View FIGURE 8 ). Paramere elongated, club-like, strongly bent laterally; inner margin with conspicuous carina ending at rounded apex of bent part ( Fig. 8B View FIGURE 8 ); anterior face of bent part strongly concave. Proctiger with large tufts of setae separated by small carina; posterior face pentagonal ( Fig. 8B View FIGURE 8 ) and transversly concave, base of the setae on lateral margin projected (but not visible due the setae). Ventral rim central excavation widely and shallowly excavated; expansions well-developed. tumid and rounded, surpassing level of posterolateral angles in ventral view, setose ( Fig. 8C View FIGURE 8 ). Female ( Fig. 8D View FIGURE 8 ). Gonocoxites 8 slightly convex, posterior margin angulate; inner angle covering almost half of gonocoxites 9; sutural border slightly divergent in distal half. Gonapophyses 8 barely exposed.

Comments. Breddin (1907) said that E. trabecula   is similar to E. quadridens   mainly because of the ratio between eye width and pronotum length; however, this is a not reliable character. A variation among specimens was observed and the posterior margin of gonocoxites 8 can be less slanting than shown ( Fig. 8D View FIGURE 8 ). Females of H. trabeculus   have a characteristic gonocoxite 8 with its angulate posterior margin and sutural border divergent on distal half ( Fig. 8D View FIGURE 8 ). The other female with subrectangular gonocoxites 8 is H. claricolor   , but the inner angle of gonocoxite 8 in H. claricolor   is rounded and sutural border excavated in “U” ( Fig. 3D View FIGURE 3 ), also laterotergites 9 have distal angle rounded (acute in H. trabeculus   ). Males of H. trabeculus   ( Fig. 8B View FIGURE 8 ) have paramere club-like and projected laterally like in H. claricolor   ( Fig. 3B View FIGURE 3 ). But, in H. trabeculus   inner carina is higher than in H. claricolor   and reaches the apex of the paramere ( Fig. 8B View FIGURE 8 ); superior process of genital cup is laminar and straight; expansions of ventral rim are tumid, and posterior face of the proctiger is wider than long ( Fig. 8B View FIGURE 8 ). In H. claricolor   the inner carina is low and ends up in the middle of the paramere; superior process is narrow, curved with a median projection; expansions of ventral rim are flat, and posterior face of the proctiger is longer than wide ( Fig. 3B View FIGURE 3 ).

Distribution ( Fig. 21 View FIGURE 21 ). SURINAME; FRENCH GUIANA: Saint Laurent du Maroni; BRAZIL: Roraima, Amazonas, Pará, Rondônia, Mato Grosso; BOLIVIA: Beni.
