SYNTYPES 1♀ Sierra Leone (pres. by Rev. D.F. Morgan); 1♀ no locality given (pres. by E. Doubleday) [NHMUK]. The syntype from Sierra Leone is most probably the holotype of Zonilia zebu. Selection of this specimen as lectotype of Pachylia aequivalens would make Zonilia zebu a junior objective synonym.
