are synonymous with other taxa, and the taxonomic status of
each represents the present understanding of their taxonomic
validity as reflected in their nomenclature (i.e., there are
no potentially polytypic species). Except for two
typographical errors in the spelling of a family name
[Cambaridae (not Camabaridae) for Orconectes williamsi] and
one species name [Cambarus hiwasseensis (not hiwassensis)],
indicated on the species list, the spellings are correct.
None are in need of taxonomic studies, although some should
be reevaluated in terms of their presently known ranges to
ascertain if they should remain as candidates on the federal
list. Notes concerning the 40 species on the list are enclosed.
for listing as category 2 species.
studies (e.g., C. catagius, C. georgiae, C. parrishi, C.
miltus, P. lagniappe, P. lylei, D. youngineri) and the
results of these field investigations should be incorporated
into any decisions regarding their present status on the
list.
Many of the taxa listed are cave inhabiting species (T.
monae, C. tartarus, Orconectes species new, P. acherontis,
P. antrorum) exhibiting the limited range, low fecundity,
small population sizes, and susceptibility to groundwater
pollution typical of obligate cavernicoles. In this
category are additional species that qualify as candidates
but are not on the list (e.g., recent list of Florida's rare
taxa).
Sixteen of the 40 taxa are primary burrowers (C.
catagius, C. miltus, D. youngineri, F. burrisi, F. danielae,
F. gilpini, F. gordoni, F. harpi, F. jeanae, F.
petilicarpus, P. barbiger, P. cometes, P. connus, P.
ferrugineus, P. fitzpatricki, P. pogum). These are species
that spend most of their life cycles in gallery systems in
the subsurface water table. Because they are so difficult
to collect, little is known of their distributions (except
C. catagius) and accumulating such information is labor
intensive and expensive.
The species on the list are good candidates and should
be monitored and/or studied, although the distributions of
some should again be evaluated based upon the literature and
museum records before initiating field studies (e.g., O.
williamsi, C. englishi, C. extraneus, C. hiwasseensis, C.
obeyensis, O. indianensis, O. virginiensis, P. plumimanus,
P. medialis).
1. Designation of each taxon as: (a) valid as listed; (b) synonymous
with another taxon; (c) potentially polytypic; or (d) impossible to
evaluate without extensive taxonomic study.
2. Correction of errors in nomenclature.
3. Identification of individuals qualified to carry out the taxonomic
studies required.
