( Fig. 1 View FIGURE 1 E–F)
Material. Holotype: Clitellate (NMA 004317): Philippines, Camarines Sur, Isarog summit (13° 39.81’N, 123° 21.89’E), 1987 m, soil, 15 May 2001, S. W. James coll. 2 paratypes: 1 clitellate (NMA 004322), 1 clitellate ( KUNHM 003013): Same data as for holotype. Other material: 2 clitellates, 5 semi-clitellates, same data as for holotype.
Etymology. The species is named for its type locality.
Diagnosis. urceolata -group with intestinal origin in XV, esophageal hearts in X–XIII, and two copulatory bursal pads on the sides of the chamber.
Description. Light-brown dorsal pigment, setal rings unpigmented. Dimensions 54–61 mm by 2.9–3.2 at segment X, 2.4–2.5 mm at XXX, 2.5–2.6 mm at clitellum, segments 91–102; body circular in cross-section. Setae numbering 44–49 at VII, 48–52 at XX; 5–9 between male pores, size and distance regular between dorsal and ventral, setal formula AA:AB:YZ:ZZ= 1:1:1:2 at XIII. Clitellum annular XIV–XVI; setae invisible externally.
First dorsal pores 12/13. One pair of spermathecal pores deep in 5/6 at 10th setal lines, sub-laterally placed, 0.18–0.20 circumference apart, distance between spermathecal pores 1.6–2.0 mm; 0.4 mm openings of copulatory bursae paired in XVIII at 10th setal lines, ventro-lateral, 0.19–0.20 circumference apart; distance between opening 1.5–1.6 mm. Genital markings lacking.
Septa 5/6–7/8 thin, 8/9 very thin muscular fiber, 9/10 absent 10/11–13/14 slightly muscular. Gizzard in VIII–X, intestine begins in XV, medium paired lymph glands from XXVII along dorsal vessel; intestinal caeca simple originating in XXVII, and extending anteriorly about to XXIV, finger-shaped sac; typhlosole very low from XXVII. Hearts X–XIII esophageal.
Ovaries and funnels in XIII, spermathecae paired in VI, with nephridia on spermatheca ducts; spermathecae with medium broad oval-shaped ampulla, duct narrower than ampulla; diverticulum ovate to globularshaped iridescent chamber, with stalk shorter than chamber. Male sexual system holandric, testes and funnels in ventral paired sacs in X–XI. Seminal vesicles two pairs in XI–XII, small dorsal lobes on upper edge, prostates in XVII–XVIII with 2 primary lobes anterior lateral to copulatory bursae, with long muscular ducts, curve around anterior half in U-shape concave posteriorly, entering center via medial part of copulatory bursae without stalked glands; copulatory bursae opening flanked anterior, posterior by sucker-like circular pads more on sides than floor; each pad with associated glandular tissue; penis a small round knob from roof.
Remarks. The intestinal origin in XV and presence of esophageal hearts in X–XIII is unique among the species in the present paper, and shared only with P. s i m s i. Differences between the two species are that P. simsi has bursal pads on the floor rather than the sides, fewer setae in all regions of the body, and closer male pore spacing. Pheretima camarinensis sp. nov. is included in James (2005) as Pheretima 061-4.
