An Updated Classification of the Recent Crustacea

ACKNOWLEDGMENTS
We sincerely thank the many carcinologists to
whom we sent earlier versions of the classification
(all of whom are listed in Appendix II). Although
not all of these persons responded to our queries
(we had a response rate of approximately 60% to
the first mailing and approximately 70% to the second)
and some saw only later versions, we felt it
appropriate to list all persons from whom comments
were solicited. Drs. Rodney Feldmann and
Geoffrey Boxshall, in addition to commenting on
sections of the classification, served as external referees
for the entire manuscript, and to both we are
extremely grateful. We mourn the loss of Erik Dahl
in January 1999, of Mihai Băcescu in August 1999,
of Arthur Humes and Austin Williams in October
1999, of Gary Brusca and Ray Manning in January
2000, of Théodore Monod in November 2000, and
of Denton Belk in April 2001, during the compilation
of this classification. Their absence is keenly
felt by all carcinologists. Deserving of special recognition
are David K. Camp for supplying much
needed information and literature for a wide variety
of taxa; Anne C. Cohen for literature on ostracodes
and maxillopods and for enlightening discussions
of that group’s presumed monophyly; William
Newman and Mark Grygier, both of whom provided
literature and enlightening comments on maxillopods;
Mark Grygier for additional comments on
interpretation of ICZN recommendations; Trisha
Spears and Cheryl Morrison for providing unpublished
molecular sequence or gene rearrangement
data for the decapods; Geoffrey Fryer for his always
direct comments concerning the branchiopods;
Gary Poore for information and literature on
several peracarid and decapod groups and for his
detailed review of our penultimate draft; Robert
Hessler for providing needed literature and for his
insightful suggestions; and Lipke Holthuis for suggesting
corrections to several taxonomic authorities
and dates in our earlier versions. Obviously, not all
of the suggestions we received were incorporated,
in part because some suggested changes contradicted
others and in part because some suggested
changes would have involved major rearrangements
for which we deemed the evidence insufficient
or incomplete. Inclusion of crustacean-related
web sites as an appendix was the idea of Keith
Crandall. We thank Todd Zimmerman, Regina
Wetzer, Todd Haney, and Sandra Trautwein in our
Los Angeles crustacean laboratory for suggestions
and assistance at various points; Regina Wetzer in
particular was instrumental in assembling Appendix
III.
We thank the Natural History Museum of Los
Angeles County, and especially John Heyning, John
Harris, and the members of the Scientific Publications
Committee, for support and for assistance
with readying the manuscript for publication. We
also thank the National Science Foundation for
partial support via grants DEB 9020088, DEB
9320397, and DEB 9727188 to J. W. Martin; NSF
Biotic Surveys and Inventories grant DEB 9972100
to T. L. Zimmerman and J. W. Martin; and NSF
PEET grant DEB 9978193 to J. W. Martin and D.
K. Jacobs. Finally, we sincerely thank Sue, Alex,
and Paul Martin and Ruthe Davis for their kind
encouragement and understanding.
