Abstract
Sectollema anisonchum n. sp., S. mucrodens n. sp., and S. truxum n. sp. from a Colombian rain forest near Araracuara, are described. S. anisollchum (♀ L=3.98–4.2 mm; ♂=4–5 mm; V =54–58; spicules=84–96 μm) comes close to S. basilgoodeyi but differs from it in having a more tapering tail and an odontostyle having the dorsal arm about 11/2 times as long as the ventral arm. S. mucrodens (♀L=3.15–3.24 mm; V=52–53.5) is recognized by its continuous lip region and odontostyle having a solid deltoid mucronate tip and its posterior third being parallel-sided. S. truxum n. sp. is similar to S. mucrodens but has a differently shaped odontostyle and tail. S. macbethi Heyns, 1965 was also found near Araracuara, Colombia.
