Diagnosis:
Holotype
complete, with 82 segments,
32mm
long, thorax
2mm
wide. Eyespots dark, placed laterally. Branchiae on segments 3, 4 and 7. Nine pairs of nephridial papillae from segment 6. Forty or more pairs of notopodia; notochaetae with distal oblique and serrated region. Uncini in double rows from segment 10 to posterior body, in double separated rows, face to face, in thorax and abdomen, and in single rows in several posterior uncinigers; uncini MF:1:4:4.
Staining Pattern:
Ventral shields stain deeply; nephridial papillae stain slightly, but darker than the remaining structures that remain, even tentacles and branchiae.
Variations:
Additional specimens are
30–47mm
long, 1.5–5.0mm wide. The ventral shields vary from
14 in
the
holotype
, to
18 in
additional specimens examined.
Discussion:
A complete description of the species is presented by
Londoño-Mesa and Carrera-Parra (2005)
. In this report the distribution of this species is expanded to include the Gulf of Mexico (Veracruz), and some islands in the Antilles as
Dominican Republic
and
Grenada
. This species differs from
T. hiata
comb. nov.
, by having branchiae on segments 3, 4 and 7, instead of 2, 5 and 8.
