Dacus (Psilodacus) merzi White Dacus (Psilodacus) merzi White, 2006: 132 Material. KENYA: 2 males, 1 female, Mt. Elgon Lodge, 1 – 6.xi.1983, A. Freidberg (TAU) Remarks. White (2006) described this species from a single male which had an almost complete (c.90%) covering of microtrichia in cell c. These males are similar but the female has a considerably reduced covering of microtrichia in cell c (around 75%) and will erroneously run to D. herensis Munro, 1984 using the key provided by White (2006) (corrected in revised key). The known males, including the holotype, all have a large inverted-V mark on the face, just below the antennal insertions. In the female this is reduced to a pair of very small dark marks.
