Synonyms:
- scientific: P. funicularia (Martin, 1907); P. bredoi (Schouteden, 1934); P. martorelli (Compte Sart, 1964)
- vernacular: Western Unicorn C.
Type locality: Old Calabar, Nigeria
Diagnosis
Male is similar to P. gamblesi and P. monoceros by (a) larger size, Hw 34-42 mm; (b) thorax with 2-3 pale stripes on each side; (c) hook of hamule short, may have 2-3 points, although this is often concealed; (d) dorsum of S10 with peak bearing 1 cone, but without tooth at base of peak; (e) cerci and epiproct both dark cerci; (f) cerci long and slender but with blunt tips. However, differs by (1) antehumeral stripe often absent or reduced to ventral half; (2) border of hamule sharply angled before hook, this hook with 2-3 points; (3) black tip of genital lobe often separated from black on dorsum of S2 by yellow band.
