Pollex (Bilobiana) sapamoroi Fibiger, new species

( Plate 7 , figs 2, 3; male genit. plate 17, figure 3, female genit. plate 24, figure 4)

Material examined.

Holotype: male, Philippines, Mindanao , Sapamoro, Curuan district, 20.xii.1961, leg. Noona Dan. Exp. 1961- 62, genit. prep. 3072 M. Fibiger. Coll. ZMUC.

Paratypes: 1 male and 1 female with same data as holotype, male genit. prep. 3076, female 3426 M. Fibiger. Colls. MF, ZMUC .

Diagnosis.

Wingspan: 10–11 mm.

Forewing: narrow, greyish brown.

Transverse lines: brown; terminal line marked by black dots between veins.

Reniform: distinct, whitish grey, outlined by black.

Hindwing: unicolorous grey with an indistinct black discal spot.

Underside: unicolorous grey.

Male genitalia.

Tegumen: narrow.

Vinculum: short, stout.

Saccus: U-shaped, short.

Fultura superior: T-shaped with long narrow arms, fused with upper middle part of tegumen and ventrally with juxta-anellus; where three arms meet, a finger-like, ventrally directed, apically blunt process arises.

Valve: shorter than wide.

Ampulla: symmetrical, long, club-like, very broad medially; densely setose with long hair-like setae bent inwards.

Pollex : relatively long, finger-like, equally broad throughout; subapically densely setose with long, hair-like setae bent inwards.

Digitus: very long, narrow, tapered, curved, directed ventrally, apically pointed; right disitus longer, wider mesially, and sharply bent, almost hooked, apically, than left digitus.

Juxta-anellus plate: huge, round, as wide as high.

Phallus: long, straight, slightly tapered towards apex; coecum long and narrow.

Vesica: with a long, straight, spine-like cornutus.

Female genitalia.

7 th abdominal segment: heavily sclerotised, asymmetrical.

Anterior apophyses: length 1½ of posterior apophyses.

Position of ostium bursae: in 7 th segment but close to 8 th segment, displaced to left.

Ostium bursae: heavily sclerotised.

Antrum: only slightly sclerotised.

Ductus bursae: coils in several loops, membranous, long, 1½ X longer than corpus bursae.

Corpus bursae: elongated; only slightly wider subapically.

Appendix bursae: arising anteriorly from ductus bursae immediately after antrum.

Differential diagnosis.

P. sapamori differs from the other species above especially by the shape of the pollex, digitus, and corpus bursae.
