177 The naming of organisms (and plant communities)
semi-naked name: see nomen seminudum, nomen subnudum, semi-naked
combination.
semispecies: (1) (zool., not nomenclatural) used to indicate the intermediate
nature of geographically isolated populations for which the exact
ranking is difficult to determine on the evidence available. (2)
(zool., unoff.) the component species of a superspecies; see also
allospecies. (3) (bot., unoff.) an incipient species, not a rank term; a
group of actually or potentially interbreeding populations, which are
chromosomally somewhat different, but not effectively
reproductively isolated from other such groups.
senior homonym: (zool.) of two homonyms, the first established, or in the
case of simultaneous establishment the one given precedence under
the Code.
senior synonym: (zool.) of two synonyms, the earlier established, or in the
case of simultaneous establishment that given precedence under the
Code; earlier synonym, older synonym.
sensu, [sens., s.]: in the sense of; often used to refer to the use of a name by
a cited author in a sense different from that of the original or some
other previous author; see misapplied name.
sensu amplo, [sens. ampl., s. ampl.]: in a broad sense.
sensu lato, [sens. lat., s. lat.]: in a broad sense.
sensu novo: (prok., unoff.) in a new sense; used after author citations to
indicate that a name is being used with either a wider or a narrower
circumscription.
sensu stricto, [sens. str., s. str., s. s.]: in a strict sense. (1) of a taxon, in the
sense of the type of its name, or in the sense of its circumscription
by its original describer. (2) (zool.), of a taxon, used in conjunction
with a name when referring to the nominal taxon in the narrow sense
of its subordinate nominotypical taxon.
separate: a copy (reprint or offprint) of a work contained in a part of a
book or other larger work (e.g. a journal), intended for distribution
(usually privately by the author(s)) detached from the larger work
which contains it but with its own specified date of publication
(imprint date); in (zool.) the distribution of separates after 1999 does
