Material examined. IG 327183-21, juvenile specimen, Honduras, Cusuco National Park [15.506299 -88.23704], 1457 m asl, M. Jocque 07/07/2013.

Description. Length 1.5 mm, diameter 0.12 mm at V, 0.15 mm at XIII; 21 segments. Two chaetae per bundle, distally straight; chaetae slightly enlarged in caudal segments, ventrally c. 45: 4 Μm in caudal segments, max. c. 35–40: 3.5 Μm in anterior segments. Ventral chaetae thicker than lateral ones, length of laterals not measurable. Epidermal glands inconspicuous, one row of pale enlarged cells at level of chaetae. Oesophageal appendages bifurcating twice, with two elongate secondary branches on each side. Pharyngeal glands 3 pairs in IV–VI, all connected dorsally, a pair of small secondary ventral lobes in V. Dorsal blood vessel from IX, midgut pars tumida in XV–XVI. Five pairs of preclitellar nephridia, from 5/6 to 9/10, anteseptale as large as postseptale, c. 25 Μm long. Coeolomocytes very scarce, small, length c. 10 Μm.

Remarks. This juvenile specimen cannot be identified to species, but by virtue of the oesophageal appendages, the pharyngeal glands and the preclitellar nephridia it belongs to a species different from H. phytotelmatus sp. nov.
