Cuticle rather thin and finely transversely striated. In one specimen (ɗ 2), subcuticular hypodermis yellowbrownish granules irregularly distributed throughout the body; pigment granules concentrated in preneural region (especially densely just posterior to the amphidial fovea) and thereafter less densely in posterior body region and tail, predominantly in ventral position. In other specimens, males and females as well, there are no conspicuous pigment granules in the anterior hypodermis. Labial region domeshaped and ... |
