3.16 Calocalanus pavoninus
Farran 1936
Calocalanus pavoninus Farran, 1936: p. 83,
fig. 3 - Tanaka 1956b: p. 380, fig. 9 - Corral,
1972: p. 4, fig. 3a-d.
Body length -
females: 0.71, 0.76mm (2 specimens)
Female. Cephalothorax 2.7 times longer
than wide, 5 times longer than abdomen.
Abdomen 2-segmented; genital somite 1.6
ti~es wider than long. Caudal rami only
~h~tly longer than wide. P5 symmetrical, 4Jomted; last joint terminating in long, strong
plumose spine with row of spinules at base.
Remarks
Farran (1936) described the female of C.
pavoninus with a 3-jointed P5. He stated that
Family Calocalanidae'
this species can be distinguished from C.
contractus, which it resembles in form and
size, by the single stout seta at the end of the
~~. We collected only two specimens, with 4Jomted P5s as reported by Tanaka (1956b)
and Corral (1972).
Distribution
Calocalanus pavoninus is mainly an oceanic
and epiplanktonic species. It has been
reported from the Gulf of Mexico and
Caribbean Sea, Canary Islands, Great Barrier
Ree~ Region, Izu Region (Japan), and the
MedIterranean Sea (Corral 1972). To our
knowledge, this species has never been
reported in Chilean or Argentinian waters.
In the present study, it was present in very
low numbers from 0-50 m at two stations in
the Pacific area of the Straits of Magellan and
at one station off Cape Froward.
