Abstract.
The
eggs,
all
larval
instars
and
the
pupa
of
Striplmopteiyx
edulis
(Boisduval,

the
type
and
only
species
of
the
southern
African
eupterotid
genus
Striplmopteiyx

are
described
and
illustrated,
including
the
chaetotaxy

INTRODUCTION
Striphmpteiyx
edulis
(Boisduval,
1847)
(Figs
1-6)
is
a
large
southem
African
species
of
Eupterotidae
(monkey-
moths)
and
the
type
and
only
species
of
Striphnopteiyx
Wallengren,
1858,
the
type
genus
of
the
subfainily
Striplinopteryginae
Wallengren,
1858,
which
currently
in-
cludes
15
genera
(Nassig
&
Oberprieler,
2008).
Striphnopteiyx
edulis
occurs
from
the
south-eastern
parts
of
South
Africa
north
into
Mozambique
and
eastern
Zim-
babwe
(Pinhey,
1975)
and
is
rather
cominon
in
KwaZu-
lu-Natal.
No
authentic
descriptions
or
illustrations
of
its
larva
have
been
published,
Boisduval's
(1847:
600)
ac-
count
in
the
original
description
of
the
species
"La

nille

evidently
referring
to
the
gregarious
larvae
of
a
species
of
Satumiidae,
which
are
often
eaten
by
local
people
there.
The
literature
(Piatt,
1921;
Pinhey,
1975;
Kroon,
1999)
does,
however,
record
both
native
and
introduced
host
plants
for
the
larva
of
S.
edulis
in
South
Africa,
respec-
tively
Cordia
caffra
(Boraginaceae),
Tecoma
capensis
(Bignoniaceae),
Acacia
mearnsii
(Fabaceae)
and
Bougainvillea
(Nyctaginaceae).
This
paper
describes
and
illustrates
the
egg,
larva
and
pupa
of
S.
edulis,
including
the
chaetotaxy
of
the
first-in-
star
larva,
froin
material
reared
in
Gennany
froin
eggs
ob-
tained
froin
a
gravid
female
collected
in
South
Africa.
The
descriptions
enable
a
comparison
of
the
immature
stages
of
this
taxon
with
those
of
a
few
Asian
genera
of
Eupteroti-
dae
and
thus
contribute
characters
to
an
eventual
recon-
struction
of
phylogenetic
relationships
within
the
family.
MATERIAL
AND
METHODS
A
gravid
female
of
S.
edulis
was
collected
at
light
on
1
1
April
2007
by
V.
V.
Z.
in
the
Republic
of
South
Africa,
in
the
RaiBsgate
Butterfly
Sanctuary
(30°53'S
30°20'E,
45
m
a.
s.
1.)
located
in
the
province
of
KwaZulu-Natal.
Iden-
tification
of
the
species
was
made
by
comparison
with
the
holotype
(Fig.
3)
housed
in
The
Natural
History
Museum,
London,
United
Kingdom.
From
eggs
laid
by
this
female,
larvae
were
reared
on
Convolvulus
and
Calystegia
(both
Convolvulaceae)
to
pupation
in
captivity
in
Germany
by
D.
S.
The
morphological
study
of
the
preimaginal
stages,
including
the
illustrations,
was
carried
out
by
S.
N.
P.
For
the
study
of
the
chaetotaxy
of
the
first-instar
larva,
specimens
were
preserved
in
70-80%
ethanol
and
cut
lon-
gitudinally
for
rapid
maceration
(15-20
min)
in
10%
NaOH
solution
in
a
double-boiler
The
head
capsule
was
cut
from
the
body
using
micro-scissors
and
the
skin
cleaned
from
tissues
using
a
micro-brush.
The
skin
was
then
washed
in
hot
water
and
dehydrated
and
hardened
with
ethanol
(sequentially
through
concentrations
of
50%,
80%
and
96%)
before
mounting
in
Euparal
on
a
glass-slide
under
a
cover-glass.
The
head
capsule
was
treated
in
the
same
way,
except
that
the
cover-glass
was
supported
by
sinall
pieces
of
glass
to
avoid
undue
pressure
and
distor-
tion.
Mandibles,
labrum
and
labio-maxillary
complex
(Figs
25,
29,
30)
were
dissected
from
the
head
capsule
and
studied
and
preserved
separately.
Three
first-instar
larvae
were
subjected
to
this
procedure.
The
preparations
were
studied
under
a
light-microscope
and
photographed
using
a
Canon
PowerShot
A570
and
an
Olympus
Camedia
C-750
camera.
Images
were
processed
using
Adobe
Photoshop
7.0,
and
colour
plates
were
pre-
pared
from
scanned
analogue
and
digital
photographs
us-
ing
CorelPhotoPaint
X3.
In
the
chaetotaxy
of
the
larva,
the
nomenclature
of
Hin-
ton
(1946)
is
followed.
