Abstract
Three new species of the genus Pheretima are described from Mount Bulusan, Sorsogon Province, Luzon Island, Philippines: Pheretima bulusanensissp. nov., Pheretima sorsogonensissp. nov., and Pheretima blackbirdensissp. nov. All are in the sangirensis-group of Sims and Easton (1972), which is characterized by having one pair of spermathecal pores in 7/8. The three new species have equatorial unpigmented stripes, the intestinal origin in XVI, spermathecae in VII, and with segmental setal counts all greater than 40. Pheretima bulusanensissp. nov. has copulatory bursae openings 0.19-0.23 circumference apart and septa 8/9/10 present. Pheretima sorsogonensissp. nov. has copulatory bursae openings 0.14 circumference apart and septa 8/9/10 absent. Pheretima blackbirdensissp. nov. has copulatory bursae openings 0.17 circumference apart and septum 9/10 absent.
