2 juveniles, Forêt de Jules, N16°11.535', W61°41.330',
256 m

Juvenile specimens

mm, no dorsal pores, spermathecal pores in line with C in 9/10, male pores in xvii, widely spaced, nephridial pores at leading edges of segments in BC. Setae AB of segments xii–xviii enlarged. Septa
6/7–9/10
muscular, gizzard in vi, intestinal origin in xiii, typhlosole origin in xiii, a thick fold with pebbly surface texture to xxiii, after that with vertical corrugations. Last hearts xi, calciferous glands complex tubular structure, ovate in xii, lacking reservoirs. Male organs not developed except immature seminal vesicles, long within xii. Spermathecae in x, spatulate. Holonephridia lacking bladders, composed of long tubules.
Remarks
. The typhlosole does not have cupped folds and/or zig-zag structure as in many species of
Glossodrilus
and of
Glossoscolex
(e.g.
Bartz
et al.
2012
). With limited and juvenile material it is not possible to positively identify the species, nor to give it a description. It could be an introduction.
