Fahri and Fitrallisan. 6 clitellates (UNTAD Oli. 0007), same data as for the sample MZB Oli. 0061. <b>Description.</b> <i>External characters</i>. Body generally cylindrical. Prostomium prolobous. First dorsal pore in 12/13. Setae 68–74 in v, 70–86 in vii, 72–88 in viii, 80–92 in xxv, and 8–12 between male porophores in xviii. Clitellum annular, xiv–xvi, smooth without setae and dorsal pores. Female pore single, mid-ventral in xiv. Spermathecal pores small, lateroventrally two paired in 5/6/7. Male porophores highly elevated, large; male pores located inside copulatory pouches in xviii. Genital markings simple, large, presetal, paired in xix–xxi, rarely xxii. <i>Internal characters</i>. Septa 3/4/5/6/7/8 thickened, 8/9/10 absent, 10/11/12/13 thin. Gizzard large, round after viii. Last heart in xiii. Intestinal origin at xv; caeca absent. Pharyngeal micronephridia well-developed on septum 7/8. Typhlosole simple. Spermathecae large, about 1–5 altogether, 1–2 per segment in 5/6 and 1–2 per segment in 6/7 (Table 6). The number of spermathecae variable in specimens (Table 6). Ampulla large and round; duct relatively short, about 1/6 as long as ampulla. Diverticulum simple, much shorter than ampulla, slightly expanded distad, and attached to the base of duct. No accessory glands. Holandric. Testes sacs paired in x and xi, small, separated, ventral, yellowish. Seminal vesicles in xi–xii. Ovaries paired in xiii, ovisacs in xiii. Prostate glands paired from xvi–xix, racemose. Prostatic ducts C-shaped, bigger distally, ending at xviii. No accessory glands. <b>Habitat and ecology.</b> Specimens were found in the yard in Margapura village, Bolano Lambunu district at 5 m asl. It was collected from sandy soils near water drainages at depth of 5–20 cm. <b>Remarks</b>. <i>Polypheretima elongata</i> is an exotic species widely distributed in Sulawesi and other regions in Indonesia (Easton, 1976). It is also commonly found in the Indochinese region (Thai, 1983; Nguyen et al., 2016).
