Parapachycerina munroi Stuckenberg, 1971: 588 . Type locality: Nangweshi , Zambesi River, Zambia.

Stuckenberg’s (1971: 588–590, figs 35 (head), 89–92 (male terminalia)) description was thorough, and does not need to be revisited. However, as mentioned above, the photograph of the wing purportedly of P. munroi ( Stuckenberg 1971: fig. 42) is that of

P. bispina (as it shows infuscation of the anterior portion of the wing and cross-veins). Furthermore, all eight specimens mentioned in Stuckenberg’s description originated from Nangweshi (16°26'S: 23°20'E) in western Zambia. This gives an incomplete impression of the distribution of the species. P. munroi is in fact broadly distributed throughout much of southern and western Africa, as the following records show .
