  • scientific: P. montanus Fraser, 1957; P. hartwigi Buchholz, 1958; P. perisi (Compte Sart, 1963); P. margaritae Compte Sart, 1967

Type locality: Fernando Po (= Bioko), Equatorial Guinea

Diagnosis

Male is similar to P. selysi by (a) posterior hamule slender, its posterior border almost straight; (b) S4-6 with pairs of yellow basal spots; (c) cerci about 2x as long as epiproct; (d) apices of cerci slender and pointed (dorsal view). However, differs by (1) ranging from C DRC to Cameroon; (2) inner branch of anterior hamule shorter than outer; (3) S10 humped, basal part of dorsal ridge abruptly arched; (4) cerci with pointed ventral tooth.
