This species can reach 65 mm (2.6 in.) in length. This dorsal surface of this species is dark brown with a darker midline. The ventral surface is brownish pink, with an alternating pattern of bright spots along the midline. Females have 24 pairs of legs; males have 23 pairs of legs. The ventral surface of the legs are pink, and the first and last leg pairs are reduced in size. The inner and outer jaw blades each feature a main tooth and two accessory teeth, and the inner blade also features 11 to 13
denticles. Furthermore, like other species in this genus,
E. totoro features a single opening for the anal gland in front of the anus and crural tubercles forming a single complex on each leg of the two pregenital leg pairs. Other traits distinguish
E. totoro from the other described species of
Eoperipatus:
E. butleri,
E. horsti, and
E. weldoni, which are considered valid species, and
E. sumatranus, which is considered a
nomen dubium. For example,
E. totoro differs from these other species in the shape of the apical piece on its dorsal primary papillae. This piece is spherical in
E. totoro rather than conical (as in
E. butleri), cylindrical (as in
E. sumatranus), or variable in shape (as in
E. horsti or
E. weldoni). Furthermore, in
E. totoro, the nephridial tubercle in the fourth and fifth leg pairs is located between the third and fourth spinous pads rather than in the middle of the fourth pad (as in
E. butleri,
E. sumatranus, and
E. weldoni) or at the proximal border of the fourth pad (as in
E. horsti). Other diagnostic features of
E. totoro include distinct types of scales on the ventral side of the body, the inner structure of the circular pits on the male genital pad, and the position and size of the anal gland pads in males. == References ==
