1. Male with median lobe of trifoliate process (viewed in profile) roundly expanded medially, narrow basally and at apex (Deeming 1971: 174, fig. 122); hypopygial prominence roundly rectangular in caudal view, developed into small, tooth-like projection at two dorsal angles (ibid., fig. 123)..................................................... vibrissana Deeming, 1971
– Without above combination of characters.................................................................. 2
2. Male with virtually entire thoracic pleura bright yellow, only anatergite infuscate; fore basitarsus with row of 4–5 fine anterior and posterior setulae longer than tarsal diameter; trifoliate process and hypopygial prominence as illustrated in Figs 9–12 .................................................................................. mulleri Deeming, sp. nov.
– Male with thoracic pleura more extensively infuscate; fore basitarsus not as described above; trifoliate process and hypopygial prominence not as illustrated above....................................................................... 3
3. Male with hypopygial prominence in caudal view trapezoidally bilobed, broadest above with deep medial emargination below (Deeming 1971: 154, fig. 40); frontal vitta of two forms, either yellow or black (aberrant colour form with yellow frontal vitta).................................................................................. secrecauda Séguy
– Male with hypopygial prominence not as described above; frontal vitta not of two colour forms....................... 4
4. Male with trifoliate process with stem paler than lobes (Muller 2015: 915, figs 46a, b), median lobe broadly heart-shaped in dorsal view (ibid., fig. 46a), very broad in profile (ibid., fig. 46b)............................... chrysohypene Muller
– Male with trifoliate process black throughout, median lobe in dorsal view not exceeding 2 × width of stem (e. g., Muller 2015: 910, figs 5a, 6a)...................................................................................... 5
5. Male with trifoliate process with median lobe narrow, apex developed into heart shape (Muller 2015: 910, fig. 5a), stem in profile bent at right angle at 3 / 5 length (ibid., fig. 5b), lateral lobes apically rounded (ibid., fig. 5b); male without modified setae on fore basitarsus; female with small, rounded tergal maculae; female tergite 8 with anterior margin with 3 lobes almost equal in length, their apices not conspicuously infuscate (Fig. 24)...................................... angulata Deeming
– Male with trifoliate process in profile gently curved throughout length (Muller 2015: 910, fig. 6b), lateral lobe viewed ventrally appearing obliquely truncate (ibid., fig, 6a); male sometimes with long, curling, irregular setulae on fore tarsus; female with larger tergal maculae tending to become triangular; female tergite 8 at anterior margin with lateral lobes much longer than median, apices of all three lobes distinctly infuscate (Fig. 28)................................... pulla (Wiedemann) 1
