Pollex (Bilobiana) sansdigit Fibiger, new species (Plate 9, figure 3; male genit. plate 19, figure 3) Material examined. Holotype: male, Philippines, Mindanao, Mt. Apo School, 15 km SW Dawao, 500 m, 22-31.x.1965, leg. D. Davis, genit. prep. 5686 M. Fibiger. Coll. USNM. Diagnosis. Wingspan: 12 mm. Forewing: relatively broad, dark brown. Transverse lines: indistinct, black; terminal line marked by black dots between veins. Reniform: distinct, round, whitish grey, outlined by black. Fringes: coloured like subterminal area. Hindwing: very small, unicolorous dark brown, without a discal spot; ventral part of the hindwing transformed to a long log-like cylindrical tube (see species-group discussion above). Male hindleg: covered with prominent, long, black, hair-like scales forming scent brush. Underside: unicolorous dark brown. Male genitalia. Tegumen: narrow. Vinculum: short, stout. Saccus: U-shaped, short. Fultura superior: T-shaped, broad, fused with upper middle part of tegument, ventrally fused broadly with juxta-anellus plate; each horizontal arm with a prominent, stout, apically blunt, ventrally directed process. Valve: shorter than wide. Ampulla: almost symmetrical; throughout its length totally fused with digitus; slightly broader subapically; densely setose with long, hair-like, inwardly bent setae. Pollex: almost symmetrical; basal part broad, longer than ampulla; with a small dorsal spine subapically, and with inwardly directed setae. Digitus: structure only apparently absent because digitus almost completely fused with ampulla; however, dorsal unscaled part and a tiny free tip on right side reveal presence of digitus. Juxta-anellus plate: large, higher than wide, hole for phallus positioned medially in plate. Phallus: long, bent, slightly tapered from middle part towards apex; broadest by ductus ejaculatorius; coecum short and narrow. Vesica: unarmed. Differential diagnosis. P. sansdigit differs from P. hamus by the almost completely fused ampulla-digitus, the process from fultura superior, the dorsal spine on the pollex, and the medially broad phallus.
