Etymology.
The
species
was
named
after
Dr.
Jean-Auguste
Barra
(
Louis
Pasteur
University
,
France
), researcher of
Seira
.
Remarks.
Seira barrai
sp. nov.
is
most
similar
to
S. maroccana
Negri
,
Pellecchia
& Fanciulli, 2005
and
S. vanderheydeni
Jacquemart, 1974
,
both
from
Northern
Africa
, in
head
mac
M
4i
,
S4
,
Pa4
absent
, Th II
with
4
medio-central
mac
(
m1‒
1i
,
m2‒
2i
)
and
5
mac
in
PmC
group
, Th
III-Abd
III
with
14, 6, 4
and
1
central
mac
,
respectively
;
and
Abd
IV
with
about
11
central
mac
(
Table
2
). However,
S. barrai
sp. nov.
differs
from
these
species
by chaetotaxy of
the
Th II
with
up to 7
mac
(
generally
) in
PmA
group
(6 in
S. maroccana
and
S. vanderheydeni
),
and
13‒14
lateral
mac
in
Abd
IV (12 in
S. maroccana
).
Seira barrai
sp. nov.
differs
also
by
Ant
IV
with
apical
bulb
apically
bilobed
(
simple
in
S. maroccana
),
unguis
without
apical
tooth
(
present
in
the
other
species
),
unguiculus
with
outer
lamella
serrated
and
with
proximal
tooth
(
outer
lamella
smooth
and
without
tooth
in
S. maroccana
),
and
manubrium
ventrally
with
0/2
subapical
and
14‒16
apical
chaetae
(0/4
and
12,
respectively
, in
S. maroccana
) (
see
Tabs
1
and
2).
Seira barrai
sp. nov.
also
differs
from
these
species
by
body
black
with
legs
yellowish
,
while
S. vanderheydeni
is
depigmented
(except
eyepatches
)
and
S. maroccana
has
transverse
white
strips
on
Abd
I‒II,
and
anterior
and
posterior
Abd
IV.
This
color
pattern
of
S. barrai
sp. nov.
is
similar
to
S. pallidipes
Reuter, 1895
,
but
the
new
species
differs
from
this
last
by
reduction
of
dorsal
macrochaetotaxy (
see
Winkler & Dányi 2017
,
and
remarks
of
S. burgersi
sp. nov.
).
Other
morphological
differences
among
the
compared
species
are
presented
in
Tables
1
and
2.
