Espèce Heterorhabdus tanneri - Planche 21 de figures morphologiquesIssued from : A. Lewis in Crustaceana, 2014, 87 (10). [p.1218, Fig.11].
Heterorhabdus tanneri (Claus, 1863): A, lateral view of labrum-paragnath complex including anterior labral lobe (Ant lobe) but without mandible; B, confocal: ventral view showing paragnaths, claw on each gnathobase and labrum.
See: http://booksandjournals.brillonline.com/content/journals/15685403.

Nota: Relative to the body axis, the average angle of the labral-paragnath complex is + 30°; the complex faces down and well forward. The anterior margin of the labrum proper is located a very short distance behind the first antenna, about 7% of the total body length. In lateral view, the labrum and paragnath are similar length and form a beak-like structure; in ventral view however, both are flatter and do not appear beak-like. In ventral view, the distal margin of the labrum bears some very small spinules and a small, roughened surface. The anterior labral lobe is short, forming a continuous extension of the labrum. The length of the complex is slightly over 11% of the total body length, 15% with the anterior labral lobe. The length of the labrum base is 40% of the complex length. The height of the labrum is slightly less than twice the length (without anterior labral lobe). The length of the paragnath base is 60% of the complex length. The height of each paragnath is slightly more than 1.2 times the length.


Espèce Heterorhabdus tanneri - Planche 22 de figures morphologiquesIssued from : A. Lewis in Crustaceana, 2014, 87 (10). [p.1219, Fig.12, B].
Heterorhabdus tanneri (Claus, 1863): B, gnathobase.
See: http://booksandjournals.brillonline.com/content/journals/15685403.

Nota: The unique gnathobase armature found in H. tanneri (comparatively to Eucalanus bungii, Metridia lucens, Neocalanus cristatus, Paraeuchaeta elongata), two spike-like teeth and a claw-likeventral tooth, along with the reported labral secretory cells found in members of the genus (Nishida & Ohtsuka, 1996) make it a very unique carnivore although the gnathobase and paragnaths could also be useful with larger particulate detritus.
H. tanneri belongs to a group that is suggested to use venom-like injections to disable their prey (see Nishida & Ohtsuka, 1996).

Après consultation des types, Morris (1970, p.2316) estime que cette espèce est synonyme de Heterorhabdus proximus Davis, 1949.
Voronina & Kolosova (1999, p.71) signalent cette espèce en Mer de Weddell, ce qui paraît douteux.
