(A.) congruus (Walker, 1869) from the Philippines, and the second from the Philippines. Diagnosis (new). Mnesibulus (Amnesibulus) zamboanga comb. nov. is characterised by the pseudepiphallic paramere [ectoparamere] with an obovate to flabellate apex; the ectophallic fold [rachis] with a pair of apical sclerites processes curved abruptly dorsad then anteriorly and inward, forming hooked acute apices; the pseudepiphallic dorso-apical process (da p) in profile view pointing dorsad (nearly 90° to the dorsum of the pseudepiphallus) and anteriorly; FWs more developed (with a false mirror and three slightly curved oblique veins). Mnesibulus (Amnesibulus) zamboanga comb. nov. is most similar to M. (A.) congruus (Walker, 1869) from the Philippines by the shape of the anal plate with a large, pale grey, oval and transverse median concavity; and having its apex truncated. However, it differs by the pseudepiphallus with its dorso-apical process of the seemingly larger and pointing more dorsad (nearly 90° to dorsum of pseudepiphallus); the pseudepiphallic paramere with an obovate to flabellate apex (instead of being narrowly hooked), and the ectophallic fold [rachis (= ...
