Report of Elena L. Markhaseva
on the results of her visit in October, 25 - November 1, 2006, in the Deutsches
Zentrum fuer Marine Biodiversitaetsforschung (DZMB, Senckenberg &
Zoologischer Museum Hamburg).
Deep sea calanoids available for the
present study were sorted from samples collected by ANDEEP I-III and DIVA-I
expeditions (2002, 2005 and 2000 respectively) above the sea bed, mostly at
abyssal depths in Antarctic and Atlantic
waters.
The study of benthopelagic calanoids collected
by ANDEEP-II expedition on board of RV Polarstern from Antarctic that have been
started in 2005 was continued for the next stage. It resulted in the
description of a new arietelloid genus Lamiantennula and MS “Lamiantennula
(Copepoda, Calanoida): a new deep-water benthopelagic genus of
Arietelloidea” by E.L. Markhaseva & K. Schulz that was recently submitted
to “Hydrobiologia”. Two more new genera: a new spinocalanoid genus [Caudacalanus]
and aetideid genus [Prolutamator] were studied in collaboration with Dr.
Knud Schulz of the same materials and new taxa descriptions are now under
preparation for publication in the near future. Representatives of all three
the above mentioned new genera were also found in the series of samples
collected by DIVA-I expedition on RV Meteor from the Atlantic waters and these
data are included in the planned MSs.
Diva-I EBS samples ## 318,
320, 326, 328, 329, 332, 335, 338, 340, 344, 348
and 350 were examined. From some samples (marked in bold) calanoids were sorted
for future studies. Unsorted calanoids, however, when possible, were
preliminary indentified up to the generic level, these are: Tharybis, Metridia,
Paraeuchaeta, Pleuromamma, Gaetanus, ?Paramisophria,
Lucicutia, Scolecitrichopsis, Xanthocalanus, calanoid
juveniles and etc., some genera found, apparently, may be considered
pelagic contaminants, like Clausocalanus, Acartia, Oithona, ? Nannocalanus,
??Candacia.Of sorted fraction 4 new taxa were selected for the research in the
near future: a new species of genus Bradyetes and the 3 new genera of
the superfamily Clausocalanoidea. They are conventionally named as: Tharybidae gen.
et sp. nov., Aetideidae gen. et sp. nov. (Prolutamator) and Clausocalanoidea
fam. gen. et sp. nov., (taxonomic placement of the latest is “insertae sedis”).
They are taken on a loan by E.L. Markhaseva in her host Institute (ZIN,
St.Petersburg) with necessary papers signed, the rest of other sorted calanoids
are left in ZMH, DZMB Grindel for future studies (see 2 attached files with the
detailed lists of these
calanoids).
