Material examined

Clitellate: PHILIPPINES: Aurora, Maria Aurora National Park ( 15.6943°N, 121.3712°E), 640 m a GoogleMaps .s GoogleMaps .l., old growth forest, in soil and arboreal habitats, 13 April 2001, S . W GoogleMaps . James coll.

Diagnosis

One pair of spermathecal pores in 7/8 at 8th setal lines, distance between spermathecal pores 3.0 mm circumferences; copulatory bursae openings 0.14 circumferences apart. Spermathecae in VIII, bursae with ring of wedge-shaped pads; intestinal origin XVII.

Description

Red-brown dorsal pigment, but absent from setal rings, ventrum I–III pigmented. Dimensions 90

4.0 mm at segment X, 4.0 mm at XXX, 4.2 mm at clitellum, segments 81; body circular in cross section setae between male pores, size and distance regular dorsally and ventrally, setal formula AA ZZ = 3:4:5:4.5 at XIII. Clitellum annular XIV–XVI; setae invisible externally.

First dorsal pores 11/12. One pair of spermathecal pores in 7/8 at 8th setal lines, distance Septa 5/6–7/8 thinly muscular, 8/9/10 absent, 10/11–13/14 thinly muscular. Gizzard in VIII–X, origin XVII, small paired lymph glands from XXX along dorsal vessel; intestinal caeca simple triangular sac originating in XXVII, extending anteriorly about to XXIII; typhlosole low fold from XXV

HISTORY on inner posterior wall, ovate iridescent diverticulum chamber, stalk shorter than ampulla (Figure Male sexual system holandric, testes and funnels in ventrally paired sacs in X–XI. Seminal vesicles pairs in XI–XII, well developed with medially placed dorsal lobes at base of shallow clefts, prostates XVI–XVIII, short straight very muscular ducts entering centre of copulatory bursae, copulatory opening flanked anterior, posterior oval pads; penial body transverse half cylinder with lengthwise pore at middle of groove.

Remarks

This singleton specimen is quite divergent from the other unnamed material and others collection from Maria Aurora as well as from most sangirensis -group species in the Philippines an uncommon intestinal origin in XVII and dorsal striped pigmentation. Spermathecae are in VIII, which is less common among members of the sangirensis group than pre-septal Copulatory bursal pads are two ovals on the bursal floor, not the typical ring divided partially into wedges around the bursal opening. Penes have the primary male pore in a groove side rather than on the tip.

Material examined

Clitellate : PHILIPPINES: Aurora, old-growth remnant at top of hill S . of Villa Aurora , in soil ( 121.3335°E) 732 m a .s .l., 14 April 2001, S . W . James coll.

Diagnosis

Solid dorsal pigmentation. One pair of spermathecal pores in 7/8 at 4th setal lines, distance spermathecal pores 1.4 mm; copulatory bursae openings 0.10 circumferences apart. Septa 8/9/10 intestinal origin XVI. Copulatory bursae with internal glandular mass and pad on roof, ring of 5 wedge surrounding bursal opening.

Description

Light brown dorsal pigment. Dimensions 72 mm by 3.4 mm at segment X, 3.5 mm at XXX, 3.8 clitellum, segments 87; body circular in cross section. Setae numbering 34 at VII, 38 at XX; 2 between pores, size and distance regular between dorsal and ventral, setal formula AA:AB:YZ:ZZ = 2:2:3:4 Clitellum annular XIV–XVI; setae invisible externally.

First dorsal pores 9/10. One pair of spermathecal pores in 7/8 at 4th setal line with large opening, edge of VII slightly overhanging, distance between spermathecal pores 1.4 mm, 0.11 circumferences Female pore single in XIV, 0.4 mm openings of copulatory bursae paired in XVIII at 5th setal line, placed, 1.2 mm distance between openings, 0.10 circumferences apart. Genital markings lacking.

Seta 5/6–7/8 thinly muscular, 8/9, 9/10 absent, 10/11–13/14 thin. Gizzard in VIII–X, intestine begins medium paired lymph glands from XXVII along dorsal vessel; intestinal caeca simple originating in extending anteriorly about to XXIV, finger-shaped sac; typhlosole low simple fold from XXVII. Hearts oesophageal.

Ovaries and funnels in XIII, spermathecae in VII, with nephridia on ducts; spermatheca with large shaped ampulla, some furrows on surface by gizzard, large barrel-shaped muscular, duct shorter ampulla; diverticulum with bean-shaped iridescent chamber on short stalk. Male sexual system testes and funnels in ventrally paired sacs in X–XI. Seminal vesicles two large pairs in XI–XII, dorsal seen; prostate gland 4–5 lobes wrapped around all but medial faces of copulatory bursae, muscular curve around lateral side to posterior, make one hairpin bend to anterior, enter posterior upper copulatory bursae; distal section of duct narrowed, attached to copulatory bursae; copulatory bursae

HISTORY

Remarks

Following the same filtering as for previous comparisons with known and provisional species, the same taxa was found. Here we only need to distinguish Pheretima sp. 3 from the Mt. Banahaw provisional Quezon sp. 2 in Table 2. The latter has more setae between male pores, fewer setae in head segments muscular stout conical spermathecal duct, and prostate glands composed of 2–3 lobes. The present has short barrel-shaped spermathecal ducts and 4–5 prostate gland lobes. Prostatic ducts differ also Pheretima sp. 3 showing much longer ducts than the short duct in the other species, which goes the copulatory bursa rather than passing it, making a hairpin bend to approach from the posterior
