The genus Lopidea Uhler is revised for America north of
Mexico. The relationship of Lopidea to other orthotyline
genera is discussed and it is proposed that the genus
Ilnacora Reuter is the sister group of Lopidea.
Forty-eight species of Lopidea are recognized in North
America, one of which is described as new. The following
synonymies are created (junior names first): Lopidea navajo
Knight = L. arizonae Knight; L. chelifer Knight = L. balli
Knight; L. paddocki Knight and L. deserta Knight = L.
bullata Knight; L. trispicata Knight = L. chandleri Moore;
L. burkei Knight= L. confraterna (Gibson); L. arkansae
Knight and L. biselli Knight = L. davisi Knight; L. denmani
Knight and Schaffner= L. falcicula Knight; L. mohave Knight
= L. garryae Knight; L. amorphae Knight and L. wisteriae
Chandler= L. hesperus (Kirkaldy); L· marginalis (Reuter)
= L. instabilis (Reuter); L. texana Knight, L. polingorum
Knight and L. matamorensis Knight = L. major Knight; L.
drakei Knight = L. marginata Uhler; L. phlogis Knight, L.
petalostemi Knight and L. johnstoni Knight = L. minor
Knight; Lopidea raineri Knight, Lopidea sculleni Knight,
Lopidea rolfsi Knight and Lopidea wilcoxi Knight = Lopidea
nigridia nigridia Uhler; Lopidea nigridea hirta Van Duzee,
Lopidea usingeri Van Duzee, Lopidea discreta Van Duzee,
Lopidea fallax Knight, Lopidea nicholi Knight, Lopidea
yakima Knight, Lopidea audeni Knight, Lopidea eriogoni
Knight, Lopidea calcaria Knight, Lopidea chamberlini Knight,
Lop idea angustata Knight, Lop idea rubrofusca Knight and
Lopidea flavicostata Knight and Schaffner = Lopidea
nigridia aculeata Van Duzee; Lopidea medleri Akingbohungbe
= Lopidea nigridia serica Knight Uhler; L. oregona Hsiao,
L. calli Knight, L. knowltoni Knight, L. dawsoni Knight, L. utahensis
Knight and L. yampae Knight = L. picta Knight; L. staphyleae
sanguinea Knight = L.s. staphyleae Knight; L. taurula
Knight, L. malvastri Knight, L. nevadensis Knight
and L. fuscina Knight = L. taurina Van Duzee; L. stitti
Knight and L. becki Knight = L. ute Knight.
A sample of 16 speciation events derived from cladistic
analyses suggests that vicariance can account for at least
50% of species generation in Lopidea. The frequency of
sympatric host plant speciation may be as high as 30% and
speciation by peripheral isolation has been rare if it has
occurred at all. / Graduation date: 1991
