A
previously
unidentified
museum
specimen
of
Plain-tailed
Nighthawk
Nyctiprogne
vielliardi
(Caprimulgidae)
by
Nigel
Cleere
Received
29
July
2003
The
Plain-tailed
Nighthawk
Nyctiprogne
vielliardi
is
endemic
to
the
rio
Sao
Francisco
Valley
in
north-eastern
Brazil
and
is
probably
the
least
known
of
all
Neotropical
nightjars
(Cleere
1998,
1999,
Holyoak
2001).
It
is
also
the
most
recent
caprimulgid
discovery
from
South
America,
two
specimens,
an
adult
male
holotype
and
a
juvenile
male
paratype,
having
been
collected
near
Manga,
Bahia
in
October
1987
and
described
within
the
genus
Chordeiles
seven
years
later
(Lencioni-Neto
1994).
The
species
was
next
found
near
Januaria,
near
Mocambinho
and
near
Pirapora
in
northern
Minas
Gerais
and
studied
in
the
field,
although
no
new
specimens
were
collected
(Whitney
et
al.
2003).
These
studies
also
led
to
its
generic
reassignment
from
Chordeiles
to
Nyctiprogne,
comments
on
the
whereabouts
of
the
two
types
and
documented
the
existence
of
a
third,
hitherto
unidentified
museum
specimen
that
was
collected
near
Mocambinho,
Minas
Gerais
in
April
1994.
The
holotype
was
confirmed
as
being
deposited
in
the
Museu
de
Zoologia
da
Universidade
de
Sao
Paulo
(MZUSP),
the
paratype
was
reported
as
not
being
held
in
a
public
institution
and
the
Mocambinho
specimen
was
recorded
from
the
Laboratory
of
Ornithology,
Universidade
Federal
do
Rio
de
Janeiro
(UFRJ).
No
further
localities
or
specimens
are
currently
known
for
this
taxon.
During
an
extensive
examination
of
the
Caprimulgidae
material
held
in
the
American
Museum
of
Natural
History,
New
York
(AMNH),
I
located
a
specimen
from
the
rio
Sao
Francisco
that
matched
the
description
of
Nyctiprogne
vielliardi.
