Caurinus dectes Russell is a minute, brachypterous scorpionfly
which was discovered at Marys Peak, Benton County, Oregon, in
1976, and subsequently described as the only representative of the
subfamily Caurininae within the Boreidae (snow scorpionflies).
Caurinus dectes is now known to range from the Olympic Peninsula
and Northern Cascades in...
The black grass bug genus Irbisia Reuter was revised. Over 18,000
specimens were examined and information concerning the biology, host
plant and distributional relationships of the species was compiled.
In addition to external characters, the male claspers and vesica, and
the female dorsal libiate plate of the bursa copulatrix and...
The genus Deraeocoris Kirschbaum of western America north of
Mexico was revised. Approximately 10,000 specimens from the Nearctic
Region were examined. Taxonomic characters used by previous authors
were reevaluated. In addition to the male parameres, the male vesica
and the female posterior wall of the bursa copulatrix and sclerotized
rings...
The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...
The Nearctic species of the genus Sympherobius
Banks are revised. Seventeen species are recorded from
the region. Two new species, S. constrictus and S.
quadricuspis are described from California and Arizona
respectively. Four new specific synonyms are proposed
(junior synonym(s) first): S. brunneus Nakahara and S.
stangei Nakahara = S....
This study was undertaken to find means of separating the
morphologically similar species of North American Trixagus and to
bring together information on Trixagus and Pactopus.
A key to separate the world's eight genera of extant Throscidae
is presented for the first time. A key to the five species of...
The western Nearctic species of the genus Phytocoris Fallen were
taxonomically revised. Over 15,000 specimens were examined.
Information concerning host plant associations and distributions was
compiled and summarized for use by future researchers. External
morphological features and characters of the male genitalia were used
to distinguish species. The genital tubercles...
A systematic study of the subfamily Dicyphinae Reuter (Heteroptera: Hiridae) resulted in a redefinition of the subfamily and included genera) and a revision of the
genus Dicyphus Fieber in the Western Hemisphere. The study entailed examination of about 14,000 specimens, including numerous noudicyphine, cimicomorphan taxa to assess character transformations. New...
