Phyllomacromia monoceros (Förster, 1906)
- scientific: P. onerata (Martin, 1907); P. clymene (Ris, 1921)
- vernacular: Black C.; (Eastern) Unicorn C.
Type locality: Tanzania, no locality data available.
Male is similar to P. gamblesi by (a) size, Hw 34-42 mm; (b) antehumeral stripe always complete; (c) hook of hamule short, may have 2-3 points, although this is often concealed; (d) border of hamule rounded (smoothly bent) before hook, this hook with 1-2 points; (e) costa largely black, not contrasting with Pt; (f) black of genital lobe and dorsum S2 usually connected by black bar; (g) S10 without tooth at base of peak; (h) cerci without basal spines; (i) cerci if short then pointed, if blunt then elongate; (j) epiproct and cerci dark. However, differs by (1) hook of hamule simple rather than bifid; (2) cerci weakly sinuous, of rather even width, tips thick and blunt.

Streams shaded by forest. Often with coarse detritus and a sandy, soft (like muddy) and/or probably gravelly bottom, and probably submerged roots. Inferred to occur from 0 to 2000 m above sea level.
