Abstract

"Through the use of scanning electron and light microscopy pretarsal structure is reviewed briefly for the Cimicomorpha and in detail for the Miridae. The following new or previously used terms describe tarsal and pretarsal structures in the Miridae: tarsal guard seta, unguitractor plate, basal claw spicules, claw hair, pulvillus, claw (with inner, outer, and ventral surfaces), setiform parempodium, lamellate parempodium, and pseudopulvillus. All pretarsal types found in the Miridae are illustrated with photomicrographs. The Bryocorinae and Phylinae are examined in greatest detail because of previously limited information on the former group and the heterogeneous nature of pretarsal structure in the latter. 'Tricobothrial maps' are presented for Psallops and for members of the bryocorine genera Bunsua, Felisacus, Monalocoris, Palaucoris, and Rhodocoris. A list of taxa examined is given. The phylogenetic implications of pretarsal and other structural features in the Miridae are investigated through the use of cladistic analysis. Relationships to the tribal and subtribal level are presented as cladograms. A classification derived by the method of 'phylogenetic sequencing' is presented and compared with classifications of previous authors, including Wagner, Leston, and Schuh, whose dendrograms are redrawn to facilitate direct comparison with those of the present paper. The following classificatory conclusions and changes herein are: the Isometopinae is shown as the sister group of all other Miridae; Psallops is given subfamily rank; the Orthotylinae of authors is recognized as a tribe within the Phylinae; the Deraeocorinae of authors is recognized as a tribe within the Mirinae; the Bryocorinae is redefined so as to include the Dicyphinae of authors. Within the Bryocorinae the tribe Eccritotarsini is recognized to include the Bryocorini sensu Carvalho (in part), as well as the Palaucorinae of Carvalho (including Pseudopalaucoris Ghauri); the Bryocorini of Carvalho is redefined to include only Bryocoris and its close relatives; and, the Monaloniini and Odoniellini combined are recognized as the sister group of the Dicyphina and given coordinate subtribal status"--P.
