Andrew Hamilton, K. G., 2014, The old-world Zygonini tr. nov. (Hemiptera, Cercopoidea, Clastopteridae), with new taxa from the related Machaerotinae, Zootaxa 3768 (4), pp. 437-459 : 451

Zygon desegregatum sp. nov.

Etymology. de -, away from; segregatum (adjective), Latin for “separated”

Diagnosis. Ivory to brown, midline of scutellum paler, dorsum often thickly maculate with black or dark brown spots ( Figs 1 A–B), in darkest specimens tylus and scutellum each with 2 bold, black patches on sides ( Fig. 9 A); frons and legs lineate with brown or black. Length: male 6.2–6.9 mm; female 7.0– 7.5 mm.

Types. Holotype male, [ NAMIBIA] S.W. AFRICA: Hoffnung Farm, 10 mi NE Windhoek, 7 Feb. 1972, Southern African Exp. B.M. 1972–1. Paratype female, same data as holotype; 5 males, 3 females, S.W. Africa, Aus., 1–2 Feb. 1929 (R.E. Turner) Brit. Mus. 1930–113; 15 males, 1 female, same data, Jan., Brit. Mus. 1930–117. Holotype and 21 paratypes in BMNH; 4 paratypes No. 21402 in CNCI.

Remarks. Specimens of this species vary greatly in colour, from almost unmarked brown, to boldly patterned in black and white. The male holotype seems to represent one extreme, and its associated female the other. This male also has abnormal hind wing venation; the first 2 longitudinal veins (R and M) unite before the wing tip, making M appear forked.

No specimens of this species were found to be suitable for barcoding.
