description: Pollex (Proma) jurivetei Fibiger, new species   
(Plate 11, figure 2; male genit. plate 20, figure 3, female genit. plate 26, figure 5)  
Material examined.  
Holotype: male, Indonesia, Seram W, Kamarlan, 128’38 E 3’20 S, 0–400 m, 16.i.–2.ii.1986, leg. A. Schintlmeister, genit. prep. 5643 M. Fibiger. Coll. MF, to be deposited in ZMUC.  
Paratypes: 2 males, 4 females, with same data as holotype, female genit. preps. 5644, 5767 M. Fibiger. Colls. BMNH, MF.  
Diagnosis.  
Wingspan: 9–10 mm.  
Forewing: narrow, brown, with black-brown costa in medial area.  
Transverse lines: black; terminal line marked by black dots between veins.  
Reniform: distinct, whitish grey, outlined by black.  
Hindwing: unicolorous brown with an indistinct black discal spot.  
Underside: unicolorous brown.  
Male genitalia.  
Tegumen: narrow.  
Vinculum: short, stout.  
Saccus: U-shaped, short.  
Fultura superior: ventrally with a huge process, which forms a relatively long sharp crest, and fuses ventrally with lower part of tegumen and juxta-anellus plate  
Valve: slightly longer than wide.  
Ampulla: positioned medially on distal end of valve; very short, club-like; subapically densely setose with long hair-like setae bent inwards.  
Pollex: broad-based, very short, triangular; subapically and outwards densely setose with long hair-like setae bent inwards.  
Digitus: short, but still longer than ampulla and pollex, tapered, slightly curved ventrally, apically blunt.  
Juxta-anellus plate: large, higher than wide.  
Phallus: very long, mainly straight but curving through 180°near apex; slightly tapered towards apex; coecum long and narrow, slightly upturned.  
Vesica: unarmed.  
Female genitalia.  
 Membrane between 8 th– 9 th and 9 th– 10 th: with a small ovoid pouch, probably serving a pheromone function.   
 7 th abdominal segment: asymmetrical; heavily sclerotised, ventrally greatly narrowed by extension from 8 th segment, including ostium bursae.   
Anterior apophyses: length 1½ of posterior apophyses.  
 Position of ostium bursae: anteriorly on 7 th segment near posterior margin of 6 th; 6 th and 7 th segments heavily fused; ostium slightly displaced to left.   
Antrum: cylindrical, 3 X longer than wide, heavily sclerotised.  
Ductus bursae: membranous, long, 2½ X longer than corpus bursae.  
Corpus bursae: globular.  
Appendix bursae: arising posteriorly from ductus bursae immediately after antrum.  
Differential diagnosis.  
 P. jurivetei differs from other species by almost all genitalic features, but is still inside the ground-plan of species in the genus Pollex. The differences between P. jurivetei and the other species in subgenus Proma are described in the other species accounts.
