“…11) Tyligma seems to be restricted to the temperate climate zone, apart from a few records from the southernmost parts of the subtropical region. This pattern matches that of Chidaea ; however, some species of Chidaea ( C hidaea crassa Löcker & Holzinger, 2019, and Chidaea orangensis Löcker & Holzinger, 2019) are recorded from northern parts of the subtropical region. Adults of Tyligma have been collected mainly from mid September until mid December.…”

“…Tyligma greatly resembles two other Australian Cixiini genera, Chidaea and Leades , in certain features, for example, Tyligma and some species of Chidaea share the undivided wax plate on segment IX in females (e.g. C hidaea etelis Löcker & Holzinger, 2019, and C hidaea armidalensis Löcker & Holzinger, 2019), the presence of platellae on both hind tarsomeres, the wide vertex, the length of the anal segment compared to the remainder of the 11th segment (same length or anal style slightly longer) and the presence of two aedeagal spines (one on each side) emerging from the apex of the phallotheca (in Tyligma almost symmetrically arranged in ventral view, Fig. 9b).…”

“…9b). However, in Tyligma , the bifurcate ventrocranial process on the phallotheca, which is present in all species of Chidaea (see Löcker & Holzinger, 2019), is replaced by a serrated margin at the cranial end of the ventral ridge (Fig. 9b).…”

Whilst examining material from numerous Australian and overseas collections, we discovered specimens representing a new, monotypic genus of the tribe Cixiini.…”

A new genus, Tyligma gen. nov., is created within Cixiini to accommodate the new species Tyligma dandavalex sp. nov. Tyligma is characterised by a swollen postclypeus and is closely related to the Australian genera Chidaea Emeljanov, 2000, and Leades Jacobi, 1928, but differs in the shape of the ventral ridge of the aedeagus in males and several other characters presented here. Occurring in the Australian Capital Territory, New South Wales, Queensland, and Victoria, the genus is restricted to eastern Australia. The species emerges in spring, feeding on native shrubs and small trees of Asteraceae and Myrtaceae and on the invasive West Palaearctic ash species Fraxinus angustifolia. In addition, we provide an updated key to the genera of Australian Cixiini.

Phylogeny and classification of Cixiidae (Hemiptera, Fulgoromorpha): A new evolutionary scenario for the most diverse planthopper family

The Cixiidae represent the most diverse family within Hemiptera Fulgoromorpha, accounting for nearly 20% of the described species. A molecular phylogenetic analysis of 147 taxa reveals a new evolutionary scenario for the family, identifying four major lineages: borystheninian (restricted to the Borysthenini), oecleinian and pentastirinian, grouped in one clade, sister to the cixiinian one. In the oecleinian lineage, the Oecleini are paraphyletic, including the Bothriocerini. Three groups are identified in the pentastirinian lineage: the Hyalesthes+, Pentastiridius+ and Oliarus+ clades. Within the cixiinian lineage, as traditionally recognised, the Cixiini tribe is polyphyletic, involving a basally separated Achaemenes clade, a newly described Chidaeini trib. nov., and the ‘true Cixiini’ clade, which itself remains paraphyletic, including the Semonini. The Andini tribe appears paraphyletic, including the Brixiini, and the position of the Gelastocephalini is yet to be confirmed. Despite its significance, the sampling remains incomplete, hindering, in our opinion, the formal taxonomic recognition of these lineages with formal ranks for a new classification of the Cixiidae. Fossil‐calibrated tree analysis indicates that Cixiidae originated in Lower Jurassic, approximately 181 million years ago. The four identified main lineages diverged during the Lower Jurassic in some 12 million years only, 155 million years ago. All currently recognised tribes and new major clades revealed with this study were present as early as the mid‐Cretaceous, around 100 million years ago; however, the Bennini tribe and the ‘true Cixiini’ clade emerged later, some 75 million years ago.

Disparity of metatibial and metatarsal cuticular and sensory structures in Cixiidae (Hemiptera: Fulgoromorpha) with a metatibiotarsal diagnosis for the tribes

A review of the cuticular and sensory metatibial and metatarsal structures in cixiid planthoppers (Hemiptera: Fulgoromorpha) is proposed, depicting both their strong disparity and the great diversity of the patterns observed. Terminology and definitions for these structures are provided. The so-called lateral teeth of the metatibia in fact are particular styloconic sensory structures, called spiniform sensilla in Cixiidae. The apical metatibiotarsal teeth are non-sensory cuticular expansions, often bearing one or several chaetic sensilla ventrally, generally distributed in an internal and an external group of three teeth each, in some instances separated by a diastema; innermost and outermost teeth are generally larger. On the first tarsomere seven to eight teeth generally occur in one row, although two rows are observed in Brixidiini. A strong diversity of conformations and patterns is observed in the second metatarsomere. A specific subdorsal sensillum, of platellar type, may be present in the first metatarsomere teeth for a few taxa. It is generally present in the second metatarsomere, either as a narrow-based acutellar sensillum or as a broad-based platellar sensillum according to the taxon. Scanning electron microscope (SEM) analyses of 54 species of cixiids from all described tribes of the family, supplemented by data from the literature, are used to provide a metatibiotarsal diagnosis for each of the tribes of Cixiidae. In the state of our knowledge of the sufficiently precise observations of metatibiotarsal structures in the Cixiidae which are available, and of the phylogeny of the group as a frame of reference for their interpretations, we note that the observed patterns are probably the result of multiple and independent convergences and evolutionary regressions. These occurred at all levels of cixiid classification. Although these patterns can be useful in the identification of taxa at a low taxonomic level, they would be less useful for phylogenetic approaches.
