Abstract
"The American diplurid genus Euagrus, distributed from Arizona south to Costa Rica, is revised for the first time. Euagrus is defined to include those euagrine diplurids with the following character states: no australotheline crescent; terminal cymbial spines; interlocking spinule patches on male femora I and II; a ventral, proximal, nonspatulate, tibia II mating apophysis with one or more large apical spines; two or three ventral mating keels on metatarsus II; no macrosetae brush on the prolateral surface of male tibia II; and two or more sclerotized stalks with unsclerotized bulbs on each (unsclerotized) spermathecal trunk. The relationships of Euagrus to other euagrine genera are discussed. A cladogram (based on outgroup comparison with the sister genus, Phyxioschema), a key, diagnoses, descriptions, tables of quantitative character values, illustrations, analyses of variation, natural history information, locality records, and distribution maps are provided for the 20 recognized species of Euagrus. Eight of these species are newly described: E. carlos, E. charcus, E. garnicus, E. gertschi, E. gus, E. leones, E. rothi, and E. zacus. Six specific names are newly synonymized: E. ravenus Gertsch and Mulaik, E. apacheus Gertsch and Mulaik, and E. ritaensis Chamberlin and Ivie with E. chisoseus Gertsch; E. empiricus Chamberlin and E. scepticus Chamberlin with E. josephus Chamberlin; and E. pragmaticus Chamberlin with E. rubrigularis Simon"--P. 205.
