Type species: Craterobathra tabellifera Meyrick, 1927 (New Ireland). 



The genus may be redescribed as follows. Head smooth, slightly 

 flattened. Ocellus posterior, very small. Proboscis developed. An- 

 tenna 5/6, slender, serrulate, simple, scape strongly elongate, top 

 slightly swollen, without pecten. Labial palpus extremely long, re- 

 curved, slender and smooth, laterally compressed, terminal segment 

 twice as long as median. Maxillary palpus very short, scaled and 

 flattened, appressed to proboscis. Posterior tibia smooth with a 

 moderate median more or less appressed tuft of bristly scales and a 

 larger similar apical tuft; spurs and tarsal joints with fine spines 

 below throughout. 



Forewing with vein lb short-furcate, lower branch only a short 

 stump. Vein 2 remote from angle, steep, 3 from before angle, 4 from 

 angle, 5 and 6 parallel, 7 to costa, 8 and 9 out of 7, 10 from well before 

 angle, closing vein weak, 11 from beyond middle, cell strongly nar- 

 rowed basad. 



Hindwing over 1/2, lanceolate, ciUa 2, veins 2-4 distant and parallel, 

 4 from angle, 5 remote, closer to 4, hardly approximated, 6 and 7 

 apparently stalked, cell being open between 5 and 6; a parting vein 

 present but very weak, supramedian, to above base of 5. 



Male genitaha with double pair of valvae, lower pair strongly 

 dilated at the top. Juxta forming a straight porrect process. Aede-

 row bow. Uncus and gnathos absent. 



Female genitaha: Genital segment conical, with a median spht. 

 Lamella antevaginahs, an emarginate, calyciform plate. Signum
