Description

Figs 106, 107, 108

Male: (Fig. 106a, b) Medium-sized; slender; total length 10.97-12.67 mm (mean 11.94 mm, Suppl. material 2). COLORATION: Dorsum of pronotum and hemelytron dark brown. Lateral surface of posterior pronotal lobe, parts of pleura, sometimes medial regions of abdominal venter yellowish. Head dorsal surface mostly yellowish to pale, sometimes brown stripes or areas more dominant; brown medial longitudinal stripes on anteocular lobe dorsal surface; brown areas on dorsal surface of postocular lobe, anteriorly broad, medially separated by yellowish stripe, narrowing and converging posteriorly; brown stripe between eye and antennal insertion; ventral surface entirely yellowish. Legs brown; meso or metafemora sub-basally, medially, or sub-apically with yellowish band(s); meso and metatibiae occasionally with inconspicuous medial yellow band; fore leg never banded. VESTITURE: Sparsely setose. Dorsum primarily consisting of moderately dense, short, erect or recumbent setae; short spine-like setae also on dorsum of head, more concentrated on anteocular lobe, and on pronotum. Sundew setae on profemur sparsely and randomly distributed. Microtrichia throughout posterior margin of membrane of hemelytron. Abdominal venter with short, recumbent setae, intermixed with sparse, moderately long, erect setae. Setae on pypophore short to long, recumbent to erect; paramere apical 1/2 with dense, very long, almost as long as paramere, erect, apically curved setae, directed mediad. STRUCTURE: Head: Cylindrical, L/W = 2.5. Eye moderately sized; dorsal and ventral margins removed from surfaces of head. Labium: I: II: III = 1: 2.0: 0.4. Basiflagellomere diameter larger than that of pedicel. Thorax: Anterolateral angle rounded, sometimes bearing protuberance, never prominently acute; medial longitudinal sulcus shallow near collar, deepening posteriorly. Posterior pronotal lobe with rugulose surface; disc distinctly elevated above humeral angle; humeral angle armed, with short tuberculate processes. Scutellum long; apex angulate, slightly projected upward. Legs: Slender. Hemelytron: Surpassing apex of abdomen by about length of abdominal segment seven; quadrate cell small and slender; Cu and M of cubital cell subparallel. GENITALIA: (Fig. 107) Pygophore: Ovoid; expanded near base of paramere in dorsal view, expansion oriented dorsad in lateral view. Medial process triangular; long; erect; nearly straight; apex in posterior view acute. Paramere: Somewhat sickle-shaped; moderately long, slightly exceeding medial process; curved ventrad; apical part enlarged. Phallus: Dorsal phallothecal sclerite shield-shaped; sharp lateral transverse ridge-like expansions; convex; apex truncate or slightly rounded; posterior margin of foramen deeply concave. Struts weakly sclerotized to non-visible through apical 1/2; apically separate, not connected by bridge; basally almost completely fused. Basal plate arm moderately robust; separate; subparallel; bridge moderately long; extension of basal plate expanded onto arm.

Female: (Fig. 106c, d) Different from male as outlined below. Larger than male, total length 15.49-17.45 mm (mean 16.53 mm, Suppl. material 2). Mostly yellowish to greenish. No dark dorsal markings of anteocular lobe; remainder of dark cranial markings less pronounced than in male. Posterior margin of posterior pronotal lobe and corium dark. Femora unbanded. Spine-like setae more conspicuous than in male. Basiflagellomere not swollen basally. Humeral angle nearly elevated to level of pronotal disc; lateral processes spinous.

Diagnosis

The dorsal surface of posterior pronotal lobe uniformly dark brown. The paramere gradually enlarged, somewhat club-shaped; the medial process with ridge-like medial elevation through apical 1/2.

Zelus kartabensis is most similar to Z. kartaboides , and the differences between the two species are presented in the diagnosis of the latter species.

Distribution

South America (Fig. 108). Countries with records: Brazil, Guyana and Suriname.
