Remarks. A species known from Mozambique and Zimbabwe ( Péringuey 1904; Gomes Alves 1963, 1976; Häckel & Farkač 2013). It was described originally from Southern Rodesia (= Zimbabwe) (Umtali) ( Péringuey 1904). Contrarily to the typical black middle transverse band pattern of the adult specimens of this species ( Figs. 9a,b ), in the adult male specimen of Mpika ( Zambia) this band extends backward to the apex ( Fig 9c ). However, the male aedeagi of all specimens are similar ( Fig. 7d ). Macrocheilus longicollis is recorded for Zambia for the first time.

Male genitalia ( Fig. 7d ). Median lobe dilated in the median region, constricted between basal bulb and shaft, apex acuminated and slightly downward (lateral view), slightly acuminated (dorsal view), apical ostium with one pair of large scaled sclerotized stripes on dorsum, bending downwards, after backwards and finally directed upwards; left paramere large and rounded, without distal tooth.

Distribution. Mozambique, Zambia, Zimbabwe.
