Description

Figs 170, 171, 172

Male: (Fig. 170) Medium-sized, total length 11.49-12.39 mm (mean 11.97 mm, Table 4.2); very slender. COLORATION: Entire surface pink; areas on hemelytron lighter, sometimes apex of membrane darkened. Femora subapically with single dark band. VESTITURE: Moderately setose. STRUCTURE: Head: Cylindrical, L/W = 2.00. Postocular lobe long; in dorsal view distinctly narrowing through anterior 2/3, posterior 1/3 constant, tube-like. Eye prominent; lateral margin only slightly wider than postocular lobe; dorsal margin removed from postocular transverse groove, ventral margin attaining ventral surface of head in lateral view. Labium: I: II: III = 1: 2.1: 0.5. Basiflagellomere diameter slightly larger than that of pedicel. Thorax: Anterolateral angle rounded, without projection; medial longitudinal sulcus shallow near collar, deepening posteriorly. Posterior pronotal lobe with smooth surface; disc distinctly elevated above humeral angle; humeral angle armed, with short tuberculate processes. Apex angulate. Legs: Very slender. Hemelytron: Surpassing apex of abdomen by about length of abdominal segment seven; quadrate cell large and broad; Cu and M of cubital cell subparallel. GENITALIA: (Fig. 171) Pygophore: Rounded; very slightly expanded laterally near base of paramere in dorsal view. Medial process broadly triangular, base indistinct; short; semi-erect; straight; basally without protrusion; apex in posterior view blunt, without modification, very slightly folded ventrad. Paramere: Cylindrical; moderately long, not exceeding medial process; directed posteriad and slightly ventrad; nearly straight; apical part a little enlarged. Phallus: Dorsal phallothecal sclerite somewhat squarish; apical portion of phallothecal sclerite not distinctly tapered, surface nearly flat, lateral margin narrowly rounded; apex deeply emarginate; posterior margin of foramen nearly straight. Struts not evidently attached to dorsal phallothecal sclerite; fused throughout. Basal plate arm slender; separate; in lateral view very slightly curved; bridge short; extension of basal plate small, confined to apex of basal plate arm.

Female: unknown.

Diagnosis

The uniquely reddish coloration of the entire body makes this species easy to recognize. The medial process is highly reduced and rather indistinct, separating Z. rosulentus from other members of the Zelus tetracanthus species group (Fig. 2).

Etymology

The specific epithet indicates the reddish-pink coloration of this species.

Distribution

South America (Fig. 172). Only known from Ecuador.
