lectotype designation (Neuroptera, Coniopterygidae)
By Bo T.rBoBn
Through the courtesy
of Dr.
Howard E. Evans, Cambridge, Mass.,I
havehad the opportunity
to
study a typ,e specimenof
Conioptergr cerata Hagenfrom
Ceylon. The species was describedin
1858 and probably basedon
a single specimen. The descriptionis very
shortbut
containsthe
important statementthat the lst
and 2nd antennal segments arethick,
long and cy-lindrical
while the other segments are moniliform. Enderlein (1906) has in spite of this statement redescribed the species asa
true Conioptergr, basing the redescription on a?
(with short basal segments of antennae)from
Patti- pola, Ceylon, and Withycombe (1925) suggests thata d from
Nuwara Eliya, Ceylon, probably represents the same species and givesa
redescription anda
figureof
the abdominal apexof that
specimen under the nameof
Conio-ptergr
cerettt Hagen. Banks (1939)on
the other hand,after a
revision of Hagen's seriesof
the species, declaresthat
the species belongsto
the genus Spiloconis Enderl., 1907,a
genusof the
subfamily Aleuropteryginae, dis- tinguishedby
"dieauffiillig
langen und dicken beiden Basalglieder der An- tennenund durch
das Vorhandenseinvon
schwdrzlichen Fleckenauf
den Vorderfltigeln". Banks reportsthat
thereis
alsoa
small speciesof
lValaco-mgza (i.e. Conioptergr) in the series which "may have been
in
a later sendingfrom
Nietner, ashe
(Hagen) hadtwo or
three sendingsfrom
Ceylon".The now available type specimen
is
labelled "CeylonlNietner", "Hagen","Type/10448"
and "C.
cerata/Hagen".It
agreeswell with the
description.I
have therefore designatedit
as lectotype of Conioptergr cerata Hagen, 1858, and have Iabelledit
accordingly.The type species of Spiloconis is S. serguttata Enderl., 1907, based on 5 ?9
from
Japan.I
havenot
been ableto
examinethis
speciesfor
comparisonwith
cerofa andit
is thereforewith
some hesitationI
am now dealing with cerata asa
Spiloconis. The lectotypeof
cerata hasvery long lst
and 2nd antennal segments; the wings are unspotted.Spiloconis cerata

The genitalia of one more speci,es of this genus, S. picticornis Banks, 1939,
have been described
by
Carpenterin
1955. The terminal and genital struc- tures of the6 of
picticornis are of the same general pattern as thatof
ceretctbut there are some differences to be noted. S. picticornis lacks plicaturae on
the 7th
segment.The 8th
segmentof
picticornisd is
dividedinto
tergite and sternite (synscleritousin
ceroto).
The aedeagusof
picticornfsis
formed as a large cylindrical bodywith
apair of
divergent arm-like processes dor- sally, which processes perhaps are homologouswith
the parameres of cerata.Carpenter states that the 9th segment is reduced
in
the picticornisd
and this is also the casein
the cerete 6.Entomol. Ts. .lrs. 89. Il. 3 - 4, 1968 一”・..¨

For
comparisonwith
the mentionedtwo
speciesI
have examined the ge-nital
structuresof a pair of
Spiloconis mctculata(Enderl.,
1906) fromAustralia:
New South Wales,Palm
Beach,23.X.1917, leg.and det. R.
J.Tillyard
(my collection; don. A. Tonnoir).
These specimens agreewell
with Enderlein's description and figureof
the wings and antennae and they maybe
supposedto
be correctly determined.An
exarninationof the type
spe-cimen,
a I from
New South \Vales, Springwood,is,
however, desirable.Enderlein described the species as
a
Helicoconisbut in
1907 he transferredit to
Spiloconis becauseof
the long 1st and 2nd antennal segments and the spotted wings. The patternof the d
genitaliaof
this species (figs.5-10)
isof quite another type than that of picticornis and cerokr, having among other things a large
9th
segment, telescopically indrarvnin
the Sth segment (figs.5 and 7). The pattern resembles very much that
of
Helicoconisbut
there are some differences. Entoprocessus are absentin
Helicoconisbut
are present in rnaculato, apically fusedto the
parameres as illustratedin
figs.8 and
10 (enf). The
parameres arefree in
Helicoconi.s, fusedwith
one another in maculctrt(fig.
10). The hypandriumis of similar
typein
Helicoconis as in ntaculatabut in the latter
speciesa pair of
additional platesis
present, situated dorsally of the hypandrium. The penis of maculatu is a large tubular orsan rvhich ends in a pair of dorsal prongs, tippedwith
a few setae, and an acute ventr:rl prong,cf.
figs7-9.
The terminal abdominal structures
of the ? of
moculutn areof
quite an- other pattern than thoseof
Spiloconis picticornis, figuredby
Carpenter.In
ntuculata the gonapophyses laterales (gl) are not fusedwith
one another asin
picticornis and they are supported ventrallyby a
small projecting sub- genital plate (fig. 11, sgp). The patternin
mrrculatn is indeed verylike
thatof
Helicoconis (cf. Tjeder, 1957, p. 103,f.
10). The bursa copulatrix (fig. 12)is
much longer and has a more coiled distalpart
than observedin any
of the described Helicoconis females. The plicaturae of segments3-4
are much snraller than are thoseof
Helicoconis.S. ntaculato
is
distinguishedfrom
Helicoconis alsoin the
shapeof
the antennae and thepalpi
(figs.l3-f5) .'fhe two
basal segmentsof the
an- tennae are much longerin
maculata thanin
the Helicoconis-species and thetip
segmentsof
the palpi are much broader thanin
that genus, thetip
seg-ment of the labial palpus of ntuculuta being almost axe-like (fig. 1a) .
It
appears,from this
comparison,that
the species cerutcr Hag. and picfr- corni.r Banks do not belong to the same fjenus as mucuktcr Enderl. An exami- nation of the genital structures of the type species of Spiloconis, the Japanese S. serguttata Enderl., is accordingly necessaryin
orderto
settle this matter of classification.llote 3
The
Conioptergr-species describedby
Withycombein
1925 as C. cerata Hag. has provednot to
belongto this
species.It is
consequently nec€ssary to rename the species, andI
propose the nameEntonol. Ts. llrs. 89. H. 3 - 4, 1968
