A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: 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...

The taxonomic value of the metathoracic wing in the Scutelleridae (Hemiptera: Heteroptera)

Creator:: Au, Eunice Chizuru
Abstract:: Classification based on metathoracic wing venation does not coincide with the existing higher classification of the family Scutelleridae. The wings of the genera in the Scutellerinae possess a similar general pattern of venation which is quite distinct from that of Eurygasterinae, Odontoscelinae, Odontotarsinae, and Pachycorinae. The Scutellerinae wings possess three...

The morphology and biology of Macrovelia hornii Uhler (Heteroptera : Mesoveliidae)

Creator:: Anderson, Aage Bernard
Abstract:: The external and internal morphology are considered and important morphological characters are found which relate Macrovelis to the family Mesoveliidae. Both macropterous and Brachypterous forms occur throughout the western half of the United States. The adults and nymphs are restricted to the margins of springs and streams during the reproductive...
