The early reports of fauna from Banaue rice terraces (Joshi et al., 2000;) Anonymous, 1985; Anonymous, 1996) showed that the rice terraces contain 4species belonging to four genera; Polypheretima elongata (Perrier, 1972), Pontoscolex corethrurus (Muller, 1856), Pithemera bicincta (Perrier, 1975), and Amynthas corticis (Baird, 1969). The 4 known species have been spotted in various locations around the world. Pithemera has an intestinal caecum originating in segment xxii whereas Amynthashas an intestinal caecum originating in the segment xxvii. Pheretimahas male pores within copulatory pouches and nephridia on the spermathecal ducts, but Pithemera, Amynthas, and Polypheretima do not have these features. Also Pheretima species generally have some dorsal pigments, but Pithemera are usually lightened, and Polypheretima are mostly unpigmented. Materials were collected from 16-18 March 2000, in rice terrace region, soils and litter layers near by the forests in the Banaue, Ifugao Province, Philippines, One new species of Pithemera as characterized by Sims and Easton (1972) was found and this new species has five pairs spermathecal pores in 4/5-8/9; distance between male pores 2.3 mm, male pores superficial on center of 0.4 mm round porophore at lateral margin; genital papillae 0.3 raised circles, paired lateral xvii, xix xviii only.
