Abstract

Three new earthworm species are described from Sulawesi, Indonesia. Two belong to the genus Pithemera Sims & Easton, 1972, namely P.suwastikai Fahri, Amaliah & Atmowidi, sp. n. and P.tadulako Fahri, Amaliah & Atmowidi, sp. n. The new species, P.suwastikaisp. n. is distinguished by a medium size (135–165 mm long, 4.5–6.5 mm diameter), four pairs of spermathecal pores in 5/6/7/8/9, 7–12 setae between male pores, no genital markings, holandry, and simple intestinal caeca. Pithemeratadulakosp. n. is recognized by a large size (217–340 mm long, 13–15 mm diameter), two pairs of spermathecal pores in 7/8/9, no setae between male pores, no genital markings, holandry, and simple intestinal caeca. Another new species, Metaphirerusydii Fahri, Amaliah & Nguyen, sp. n., is diagnosed by its large size (250–280 mm long,12–16 mm diameter), two pairs of spermathecal pores in 7/8/9, no setae between male porophores, presence of genital markings in the male region, holandry, and complex intestinal caeca. Additionally, an identification key to “caecate” species is provided to the Sulawesi’s fauna.
