Tenagomysis

Fukuoka, Kouki & Bruce, Niel L., 2005, A new species of Tenagomysis (Crustacea: Mysida: Mysidae) from New Zealand with notes on three Tenagomysis species, Zootaxa 878, pp. 1-15 : 13-14

Tenagomysis sp. ( Fig. 8 )

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, 24 Jan. 2002, 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).

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.
