Distribution ( Tables 1, 2; Fig. 195). Known from locations in Northern South Africa, Zambia, and Mozambique; captured from 40 to 1350 meters in grassveld situations near rivers and under trees from November to March.

Remarks. Afroestricus variabilis is distinguished from congeners with yellow femora by the characters in the key and those of the terminalia ( Figs. 131–140 ). Additionally, it differs from A. chiastoneurus by the yellow femora and terminalia, especially the shorter median margins of the gonocoxite. The femora are black and the median process is quite long in A. chiastoneurus .

Engels type series of variabilis consisted of three specimens, a male with yellow femora from Congo and a male with black femora and a female with yellow femora from South Africa. Unfortunately , the two males cannot be located [neither are in ZSMC or SMNS which house Engels specimens]. The South African female, in excellent condition, is in the ZSMC. To stabilize the name and concept of the species, the female is selected lectotype .

Bromley (1936) suggested that the type series of O. variabilis included two species but did not resolve the status of that species. He then described Ommatius senex and O. monroi from South Africa, one of the type localities of O. variabilis . The former have black femora whereas they are yellow in the latter species. Later, he described O. bevisi from South Africa that also have yellow femora, distinguishing it from O. munroi on color patterns, i.e. the apices of the tibiae and the bases of the male terminalia were brown in O. munroi whereas they are yellow in O. bevisi (Bromley 1946) . This study agrees with Bromley in that the type series of O. variabilis consists of two species. Futhermore, a comparison of the terminalia of specimens with yellow femora from South Africa and Democratic Republic of Congo with specimens carrying Engels identification [ O. variabilis ] labels and Bromleys [ O. munroi and O. bevisi ] labels are identical. Thus, O. variabilis , O. munroi and O. bevisi are conspecific. Since O. variabilis was described in 1929 and the other two in 1936 and 1947, the latter has priority and is the name of the species. Ommatius munroi and O. bevisi are here declared new synonmyns of O. variabilis .

Distribution ( Tables 1, 2; Fig. 195). Wide spread from equatorial Africa southward to southern Democratic Republic of Congo; captured between 580 and 1150 meters throughout the year.

Remarks. Afroestricus varipes is distinguished from congeners by the characters in the key and the terminalia ( Figs. 141–150 ). The long flagellum and the dorsal yellowishbrown to red stripe on the hind femur further characterize the species.
