    Phylogeny and systematics of the leafhopper subfamily Typhlocybinae (Insecta: Hemiptera:Typhlocybinae)
    (2007-04-25) Balme, Geoffrey; P. Sterling Southern, Committee Member; Lewis L. Deitz, Committee Co-Chair
    This research examines the phylogeny of the tribes of the leafhopper subfamily Typhlocybinae using both morphological, 73 binary and multistate characters, and molecular, 16S rDNA and Histone (H3), evidence. Seventy-five taxa were included in the morphological study, and 48 were included in the molecular analysis. The combined, total evidence, analysis used 48 taxa common to both sets of data. Results of the total evidence analyses suggested 4 tribes with the following topology: Alebrini + (Empoascini + Typhlocybini) + (Dikraneurini including subtribe Erythroneurina). This topology does not completely resemble any of the last century's major typhlocybine works, but comes closest to Dr. Young's 1952 work. Based on the results of these analyses, a revised classification is proposed. A key is provided to distinguish the tribes, and each is described with notes on distribution and evolutionary relationships, a list of the included genera (current to Feb. 2007), and illustrations of key morphological characters.
