INTRODUCTION
Over the last several years, 1 have been working intensively on neotropical
species of the genus Argia in hopes ofunraveling this bewildering complex of
describedand undescribedspecies. Much work onthis genus hasbeen doneby
Mrs Leonora K. Gloyd over the last 40 years. During several visits to the
Universityof Michigan, 1havehadtheprivilege ofexamining therichholdingsof
thisgenus.Gloyd hadalready puttogetheracomplete listofallnamesusedunder
Argia, and several species ofthe genus were described by Longinos Navas.
Resolutionof names proposed by Navas has normallybeendifficult owing to
inadequate descriptions and concomitantunavailability oftypes.
Duringthe 1930’s, Gloyd hadtheforesighttoborrowseveraltypespecimens of
Argia namedby Navas while he was stillalive. Among this materialwas the
holotype femaleof Argia theodoridescribed by Navas in 1934from Caixlas
[sic], Brazil.
KENNEDY (1936: 811), in discussing T. carota Kennedy, stated:
’’AmongtypesofspeciesofArgialoaned the UniversityofMichiganforstudybyMrs.Gloyd,Navas

JURZITZA(1980) described Telebasisaureipennis basedonthreemalesfrom
MisionesProv., Argentina, and stated thatthis species was closesttoT. carota
(’’DieneueArtstehtderTelebasiscarotaKennedy, 1936nahe;dieBestimmungs-
tabellevon ST.QUENTIN(1960)fiihrtzudieserArt hin”).Throughthekindness
of Dr Gerhard Jurzitza, I was ableto borrow one oftheparatype males in
1989 and made illustrations of various diagnostic characters (Figs 1-4). In
November, 1990,1visited theFloridaStateCollectionofArthropods(FSCA) at
theUniversityofFloridaatGainesvilleandDr MinterJ.Westfall,Jr.,loanedme
someNavastypematerial describedunderthegenusArgia. Among thesespeci-
mens was the holotype female of A. theodori, whose diagnostic characters I
illustratein Figures 5-6. 1alsoexaminedasmallunidentifiedseriesoffive male

theodori includes Rio Grande do Sul and Santa Catarina states, Brazil, and
Misiones Province, Argentina.
REDESCRIPTION OF TELEBASIS THEODORI
Becausetheoriginal descriptionofTelehasisiheodori isnotdetailed andis generallyunavailable
toodonatologists,I include a descriptionoftheholotypeand a coupletwith which to separate
femalesofT. Iheodori and T. caroia.
HOLOTYPE female.— Entire face pale orange, especially so on labrumwith
following areas black: a mediantriangular spot encompassing ocellar triangle
with a long narrow anterolateralarmextending frombehind lateralocellusto
and touching large subquadrate spot adjacent to compound eye, the same as
showninfig. 1 ofJURZITZA(1980); fronsangulate, rearofheadentirely pale.
Prothorax(Fig. 6) entirely pale with hintof darkermedianline atjuncture of
middlelobes and with a pale area oneither sidefollowed morelaterally by a
diffuselongitudinal darkline; anteriormargin ofhind lobe with a pairof short
anterolateral digits appressed against median lobe. Synthorax entirely pale,
more so laterally, with a narrow black middorsal stripe adjacent to antealar
crest and middorsal thoracic carina(Fig. 5), its upperend barely touching
antealarcrest, itslowerend diverging anterolaterally encompassing medial0.5
