INTRODUCTION
We continuehere our studies ofPolythoridae with detailed considerationof
thegenusEuthore.Afterthisatabularcomparison ofthe3 mostcommongenera,
Cora, Polythore, Euthore,is given followedby akey toall8 generaofPolythori-
dae.
THE GENUS EUTHORE
SELYS(1869) establishedthegenusEuthorewithfasciataas thetype species.
MONTGOMERY (1967)keyed 9species and detailedtheirtype depositions. DE
MARMEES (1981, 1982, 1988a)consideredtaxonomy, ecology, distributionof
Venezuelan species and BICK & BICK (1990) removed Euthore terminalis
(McL.) from Euthore, returning it to Cora.
The 8 species inEuthore with theoccurrence ofeachby country are:
fasciata (Hagen in Selys, 1853):Venezuela,Colombia, Ecuador.

We attempted to study specimens in most ofthe large Odonata collections,
but, except for E.fasciata, disappointingly few were available, a contrast with
otherPolythorid generawhichwepreviously studied.However,B.E. Montgome-
ry’s unpublished notes andfigures, mostlyoftypes, wereavailableintheArchives
of the InternationalOdonata Research Institute, Gainesville, Florida, and we
examineddirectly types offasciata, plagiata (Selys) andmirabilis.

SPECIES KEYTOEUTHOREMALES
The penis horns of 5 species figured by KENNEDY (1919) as well as the
horns of2 figured by DE MARMELS (1988a) are similar. Ourexaminationof
all 8 species showed thepenis tobe similar, the apical horns ofmost measuring
0.20or0.25mm. We donot considerthepenis a good diagnosticcharacter.Also,
because species differenceswere not found in either abdominal appendages or
body colourpattern, the key is basedentirely on wing colorpattern. Determina-
tions shouldbe confirmedby species accounts, figures andtables.

SELYS (1873, 1879)stated thatthefrontwingsofplagiatafemales are banded,those offasciata
hyaline.This differenceis obvious in thetypesofthe taxa which westudied, but MONTGOMERY
(1967)statedthatthesefemaletypes,presumablythe samespecimens,wereidentical andthatplagiata
isasynonym offasciala.SELYS(1873, 1879)gaveverybriefnotes forhis Imaleplagiatasurmising
thatitwasonlyavarietyoffasciala.There isnomaletype ofplagiatabutwe studiedthe maletype
offasciala. DE MARMELS (1982, 1988a, 1990)assigned Venezuela specimensto E. f.fasciata
(northern).E.f.plagiata(southern)and toformsulfurata(2 small northernpopulations). However,
all 3 ofhis”plagiata”females hadhyaline frontwings (DE MARMELS, 1988a,p. 93) as inthe
fasciatatype.
Our materialofE.fasciata included2 kinds ofreadily distinguished females:
those with hyaline front wings as in thefasciata type, those with banded ones
as in the plagiata type. The hind wings of both kinds were very similar and
overlapped in all measurements.
Specimens ofE.fasciala includedmaleswhichdifferedfromall othersby the
opaque yellow or cream wing color andmales in which theopaque wing color
was whiteand the wing color patterns very similar. Distinction between these
latterwasmanifestonly whenmaleswere foundassociatedinthesamecollection
with the 2 very differentkinds offemales. One kindofmalewas collectedwith
femaleshaving frontwings as inthefasciata type,theother withfemaleshaving
front wings as in theplagiata type. Measurementsof hind wing color patterns
ofvarious populations (Tab. II), showedthat these2 kinds ofmalesoverlapped
in mostcharacters. Thus,E.fasciata is polymorphic with 3 forms.They are only

formsbecausewedidnot detectgeographical orecological isolationnorstructural
differencesand because ofoverlap (Tab. II) in so many wing characters.The 3
formsaredesignated:.)1)sulfurata,following DE MARMELS(1982),(2)fasciata
because ofassociation withfemales having colorless front wings as inthe type,
(3) plagiata from associationwith females having bandedfront wings as in that
type.
Formsulfurata is represented by males only, all fromMirandaState,northern
Venezuela.Theusually pale wing area is sometimes clearly yellow as in the DE
MÄRMELS(1981) photo, sometimesonly cream-colored.
Formsfasciata andplagiata occur inVenezuela,ColombiaandEcuador,both
forms having been collected from the same localities. Because the male hind
wing color patterns overlapped in most characters (Tab. II), some specimens
could not be assigned confidently to either form. Indeed, without associated
females, placement ofmost males in either form is risky. The best diagnostic
character isthe slightly larger(Figs 1,2; Tab. II) apical transparency in thehind
wings of some specimens offormplagiata.
Despite theobviously greatdifferenceinfrontwings,thehindwings offemales
ofthe 2 forms were very much alike, overlapping in every wing color pattern
studied. This hind wing similarity in both sexes supports our hypothesis that
neitherform is a separate species or subspecies.
In each of2 collections(Colombia,Ecuador) a male was associatedwith a
bandedfront wing female.Inanother fromVenezuelaamalewas associatedwith
a hyaline front wing female. The fact that all 3 males (Tab. II) are essentially
alikeshows thatvery similarmalesoccur closely associatedwith2 very different
kinds offemales.Twokinds of femaleswithinwhatseemstobethesamespecies
is similarto theconditiondescribedforPolythoreproceraSelys (BICK& BICK,

type locality, but we do have 6 specimens from there.
E. meridana has been designated a race or subspecies offastigiata (SELYS,

similar(Figs 4, 8; Tab. Ill), but we judge each to be a separate species (as did

SELYS (1853, 1854)listedBahiabutin 1869questioned that locality. MONT-
GOMERY (1967), possibly thinking ofBahia state,gave Brazil. Ifthisis indeed
the Selys locality, it wouldbe far east ofall records ofthe genus. The correct
locality maybeBahia deCaraquez on thePacificcoastofEcuador. Nevertheless,
E. hyalina is widespread, reaching Guyana andsouthern Peru.

TheCaldaslocality, the only one additionaltothetype, is atno greatdistance
from theoriginal. Wings ofleroiihave beenconsidered(RIS, 1981;MONTGO-
MERY, 1967)exceptionally broad,but those of some specimens offasciata are
almostas wide. The2 species are readily distinguished: the hindwing darkband
of leroii (Fig. 7) reaches the apex, whereas fasciata (Figs 1, 2) has a 3-8 mm
clear apical area.
RIS (1918)stated thatboth frontandhind wings ofleroiifemalesarebanded.

Although meridanasometimeshasbeen consideredasubspecies offastigiata,
thereis littlepossibility ofconfusing thetwo becauseofthe muchmore limited
extent ofthefront wing dark infastigiata. E. meridanadiffersalso from leroii
andfasciata: in meridanathehind wing (Tab. ill) dark band is much narrower
(5-7 mm) than in leroii(12) and inmeridanathe widthof white(13-17 mm)is
greaterthan infasciata (4-11).
