Introduction

The species of this genus look externally very similar to the many described and undescribed species of Kahaono Kirkaldy which are also elongate, parallel-sided leafhoppers, more or less flattened dorsoventrally to fit with their preferred habitat on the vertical leaves of Eucalyptus l'Hér. (Myrtaceae). However, the male genitalia, particularly the subgenital plates and parameres are modified in a bizarre fashion and are far more complex than those of Kahaono species. Dworakowska (1972, 1993) has recognised six species in the Australian fauna but at least an additional 13 species are known in collections. The six described species are distributed across the tropical parts of mainland Australia but the genus distribution, when the known but undescribed species are included, covers most parts of the continent and Tasmania, although there are no records yet from Victoria or the Australian Capital Territory. The generic name has been formed by adding the Polish word "dziwne" meaning "strange" to "ono" which links the name to Kirkaldy's two similar Australian dikraneurine genera Aneono and Kahaono.

Diagnosis

Head proportions and wing venation like those in Kahaono Kirkaldy but male genital apparatus dissimilar. Subgenital plate produced far beyond pygophore side; anal tube as long as subgenital plate, thin; paramere solid, composed of two parts, of equal length as subgenital plate. Abdominal tergites and genital segments not pigmented. Pygophore side provided with upper hook as in Kahaono and with thin and long microsetae at upper and hind margins. Subgenital plate spoon-like, with an additional small slightly sclerotised plica at outer margin near tip. Setosity of subgenital plate consisting of not numerous minute microsetae scattered on its apical half and several (in known cases two or three) very long, rod-like macrosetae on ventral surface in the centre. Paramere provided with an additional arm which is very long, sclerotized and ornamented with teeth or ledges on its inner surface. Connective V-shaped. Aedeagus compressed anteroposteriorly. Abdominal apodemes short (Dworakowska 1972).
