Figs 182, 183

Male: unknown.

Female: (Fig. 182) Medium-sized, total length 14.18-14.95 mm (mean 14.57 mm, Suppl. material 2); slender. COLORATION: Most of dorsal surface brown, anterior pronotal lobe yellowish. VESTITURE: Sparsely setose. Head with inconspicuous, short, erect and recumbent setae, more dense dorsally, some slightly larger erect setae ventrally. Anterior pronotal lobe with short, erect and recumbent setae; posterior pronotal lobe with short, erect and recumbent setae. Abdomen with short, erect and recumbent setae. STRUCTURE: Head: Cylindrical, L/W = 2.34. Postocular lobe very long; in dorsal view distinctly narrowing through anterior 1/2, posterior 1/2 constant, tube-like. Eye smallish; lateral margin only slightly wider than postocular lobe; dorsal and ventral margins removed from surfaces of head. Labium: I: II: III = 1: 2.3: 0.5. Thorax: Anterolateral angle rounded, without projection; medial longitudinal sulcus shallow near collar, deepening posteriorly. Posterior pronotal lobe with finely rugulose surface; disc distinctly elevated above humeral angle; humeral angle armed, with spinous processes. Scutellum moderately long; apex angulate. Legs: Very slender. Hemelytron: Slightly surpassing apex of abdomen, not more than length of abdominal segment seven; quadrate cell moderately sized; Cu and M of cubital cell subparallel.


This species can be recognized by the pronotum bicolorous, anterior lobe yellowish and posterior lobe dark brown; the humeral angle with long spinous process. Similar to females of Z. truxali , but the legs are not banded and the anterior pronotal lobe appears to be more humped than that in Z. truxali .
