Suragina agramma has an overall orange-yellow appearance (Figs 9, 10), the thorax without a presutural darkened spot or median vitta on the scutum (Fig. 1). Wing uniformly light brown suffused without apparent darkened substigmal marking (Fig. 37). It is most similar to S. copelandi Muller, sp. nov., however, it differs from it by having the fore and hind tibiae yellow to orange-yellow, whereas S. copelandi Muller, sp. nov. has the tibia dark brown to black. Additionally, S. agramma has the lateral margins of tergites 2–4 concolorous to the rest of the abdomen compared (apart from a slightly darkened margin on tergite 2 in some specimens) to the dark lateral margins in S. copelandi Muller, sp. nov. Remarks. Stuckenberg (1960) notes “ eyes not contiguous ” for the male from Vumba, but upon examination, the said specimen has eyes touching briefly, not “ very narrowly separated ” throughout. The Vumba specimen has markings on tergites 1 and 2, these are absent from the Eshowe specimen of Stuckenberg (1960). Similarly, the current Kenyan specimens examined also have tergites 1 and 2 with some slight markings similar to that of the Vumba specimen as described by Stuckenberg (1960). Redescription.
