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
). Anterolateral margin with some brown punctures. Male (
Fig. 8
A–C). Pygophore with dorsal rim sinuous, shallowly excavated (
Fig. 8A
). Superior process of genital cup laminar with outer corner protruding; adjacent to dorsal rim (
Fig 8B
). Paramere elongated, club-like, strongly bent laterally; inner margin with conspicuous carina ending at rounded apex of bent part (
Fig. 8B
); anterior face of bent part strongly concave. Proctiger with large tufts of setae separated by small carina; posterior face pentagonal (
Fig. 8B
) 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
). Female (
Fig. 8D
). 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
). Females of
H. trabeculus
have a characteristic gonocoxite 8 with its angulate posterior margin and sutural border divergent on distal half (
Fig. 8D
). 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
), also laterotergites 9 have distal angle rounded (acute in
H. trabeculus
). Males of
H. trabeculus
(
Fig. 8B
) have paramere club-like and projected laterally like in
H. claricolor
(
Fig. 3B
). But, in
H. trabeculus
inner carina is higher than in
H. claricolor
and reaches the apex of the paramere (
Fig. 8B
); 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
). 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
).
