)
Material examined
NIWA
3957: 1 ɗ (broken,
6.2 mm
from tip of rostrum to posterior end of last abdominal somite), stn NE071,
41°25.6´S
173°27.6´E
, Nelson,

, 7 m, epibenthic sled.
Remarks
This unidentified specimen lacks the uropods and the telson. However, it is readily distinguished from other species of the genus, except for
T. novaezealandiae
Thomson, 1900
, by the armature of the fourth pleopod (
Fig. 8
F, G).
FIGURE 8.
Tenagomysis
sp. ♂, NIWA 3957. A, anterior part of body, dorsal; B, left antenna, dorsal; C, second endopodal segment of left maxilla, dorsal; D, sixth left thoracopod, anterior; E, first left pleopod, anterior; F, fourth left pleopod, posterior; G, distal part of fourth right pleopod, anterior.
The fourth male pleopod of
T
.
novaezealandiae
has not been described (
Thomson 1900
,
Tattersall 1923
). The present specimen can be distinguished from
T. novaezealandiae
by the rounded anterolateral corner of the carapace, which is pointed in
T. novaezealandiae
.
This unidentified specimen is probably a new species, but as the specimen is not fully intact, it is recorded as
Tenagomysis
sp. in the present study.
