  Type species:

   Diemoides smithtoniensis Evans, 1938 by original designation.

Introduction

This is an endemic Australian genus with nine described species distributed over most of the eastern seaboard from Tasmania to the islands of Torres Strait. Many species are distinctively marked with colourful bands, often with red or orange on the head and thorax. The type species, D. smithtoniensis Evans, is found in the SE corner of the continent and Tasmania. Diemoides was synonymised with the Palaearctic/Oriental genus Paralimnus Matsumura by Evans (1966) but reinstated by Day & Fletcher (1994).The genus was revised by Fletcher (2017).

Diagnosis

The ventral surface of the head is evenly convexly rounded, the antennal pits are shallow and the apical margin of the head is broad. The ocelli, which are on the upper border of the apical margin, are well in front of the eyes but closer to the eyes on each side than to each other. The dorsal surface of the head is arrow-shaped, the coronal suture is distinct and the width of the crown is greater than that of the eyes. The pronotum, of which the anterior margin is almost straight between the eyes, is narrow laterally and the propleurae separate the eyes from the bases of the tegmina. The tegmina have narrow appendices and the anal veins are fused medially. The hind tibiae have a few very minute spines set between the bases of each of the largest spines (Evans 1938).

Medium sized leafhoppers, narrow in build. Antennae long. Anterior margin of head usually with fine transverse lines. Tegmen with reflexed costal veins. Male pygofer lacking accessory process. Male connective lacking apical paraphyses at apex of stem which is articulated with base of aedeagus (Fletcher 2017).

Introduction

Despite being well represented in collections from a wide range of localties along the eastern seaboard of Australia from Torres Strait to Tasmania, this species remained unnamed until 2017. It differs from other species in the genus in its drab brown colouring lacking distincctive markings.

All stages: phloem feeder.

Diagnosis

This species is remarkable in the inner structure of the male pygofer which bears round denticulate lobes which sit either side of the aedeagal apical process when the aedeagus is not in use. Such lobes are not found in other species of the genus. The species also lacks the brightly colored markings found in many other species of the genus and is generally a drab brown color, similar to that of D. linnavuorii from which it differs in the structure of the aedeagus, parameres, subgenital plates and pygofer (Fletcher 2017).

Diagnosis

This species is similar in appearance to D. sagittatus Fletcher which also has the Vshaped chevron marking on the vertex and pronotum with a longitudinal stripe medially on the pronotum but in that species the markings are all red while in D. chevron the median stripe is much paler than the chevron. In addition, this species has two dark fine lines on the apex of the head but D. sagittatus has four. The structures of the male genitalia also clearly differentiate between the species (Fletcher 2017).

Diagnosis

This species is similar in genitalia features to D. chevron, D. sagittatus and D. storeyi all of which also have the subgenital plates bearing long apical processes and with the marginal macrosetae limited to a small group near the base.

Introduction

This is the most colourful species of the genus with bold red markings in the shape of an arrow extending across the head and thorax. It has been recorded from the Wet Tropics of North Queensland to south of Port Macquarie on the New South Wales North Coast. It has been swept from dry sclerophyll forest and dune vegetation as well as being caught in malaise traps in rainforest.

Diagnosis

This species is similar in general appearance to D. chevron except that the median stripe of the pronotum has the same hue as the Vshaped banding of the vertex and pronotum whereas in D. chevron, the median stripe is paler than the other marking. In addition, D. chevron has two transverse lines across the front of the head with indications of a third at the front margin of the red band whereas D. sagittatus has four dark bands extending from eye to eye. The lateral processes of the aedeagus are also larger and more obvious in D. sagittatus than in D. chevron. In male genitalia, it is most similar to D. linnavuorii which lacks the distinctive red markings of this species (Fletcher 2017).

Introduction

This species is quite colourful although more subdued when compared with certain other species of the genus. It has been recorded in the Wet Tropics of North Queensland and near Coen on Cape York Peninsula. The name honours the late Dr Courtenay Neville Smithers,
formerly of the Australian Museum, Sydney, who was a mentor to many young entomologists, one of the pioneers of citizen science in Australia with his butterfly banding program and one of the key people in the establishment of the Australian Entomological Society in 1965.

Diagnosis

Head ventrally pale brown, apical margin with three black and two white transverse stripes; ocelli red. Crown white suffused with pink medially. Pronotum bright red anteriorly, grey posteriorly. Scutellum with the anterior angles red, the remainder white. Tegmen hyaline with brown areas between the veins and the costal margin partly white; border of tegmen and anal veins red, other veins brown. Thorax and abdomen ventral surface black with white markings. Legs white with black markings. Length 4 mm (Evans 1938).

The connective in D. smithtoniensis is unusual in having the stem elongated and much longer than the lateral arms. In the other known species of the genus, the stem is not so elongated and usually only slightly longer than the arms, except in D. anomalus Fletcher in which the arms are longer than the stem. The structure of the subgenital plates is also unusual amongst leafhoppers with the apical section diverted laterally, somewhat membranous and bearing macrosetae on its inner margin. This feature is also found in D. smithersi Fletcher, D. brunneus Fletcher and D. sueshephardae Fletcher (Fletcher 2017).

Diagnosis

This species forms a group with D. chevron Fletcher, D. sagittatus Fletcher and D. linnavuorii Fletcher in which the subgenital plate extends posteriorly to form an elongate apical process and with macrosetae limited to a small number on margin near the base. In addition, the parameres have a poorly developed preapical lobe and an apical process which is distinctly bent rather than curved laterally. This species also exhibits a chevron shaped reddish marking dorsally similar to those found in D. chevron and >i>D. sagittatus although it is not as distinct as in those species. All four species also have a pair of elongate linear lateral aedeagal processes although in D. storeyi and D. chevron these are mounted near the base of the shaft while in D. sagittatus and D. linnavuorii they are mounted laterally on the shaft above the base (Fletcher 2017).

Introduction

This beautiful leafhopper is distributed from near Cooktown in the Wet Tropics of North Queensland across Cape York Peninsula.

This species has some similarity to D. brunneus Fletcher which also has a flat plate-like extension at the apex of the aedeagal shaft although D. sueshephardae lacks the internal lobes of the pygofer found in D. brunneus.
