Remarks.
In
the
original
description
S. mantis
was
not
compared
with
most
species
from
the
Western
Palearctic
region
with
similar
chaetotaxy.
Seira mantis
is
most
similar
to
S. uwei
Barra
, 2010
by
head
mac
M
4i
,
S4
and
Pa4
absent
,
basomedian
labial
field
with
chaeta
R
smaller
, Th II
with
4
medio-central
mac
(
m1‒
1i
,
m2‒
2i
)
and
5
mac
in
PmC
group
, Th
III
‒
Abd
IV
with
14, 6, 4, 1
and
12
central
mac
,
respectively
;
and
anterior
legs
of
males
with
spine-like
chaetae
(
see
Tabs
1‒2). However,
S. mantis
differs
from
this
species
by Th II
with
6
mac
in
PmA
group
(up to 8 in
S. uwei
),
Abd
IV
with
14
lateral
mac
(13 in
S. uwei
),
Ant
IV
annulated
(
normal
in
S. uwei
),
unguiculus
without
basal
tooth
(
present
in
S. uwei
),
and
manubrium
ventrally
with
18
apical
chaetae
(16 in
S. uwei
).
Seira mantis
differs
also
from
this
species
by
male
legs
I
with
15
baster-shaped
chaetae
on
tibiotarsus
,
while
S. uwei
has
20
spine-like
chaetae
.

comparisons
among
species
