New lineages of Lebinthini from Australia (Orthoptera: Gryllidae: Eneopterinae)

Keywords: Lebinthini, Eurepini, taxonomy, Australia, new genus, new species

A monograph concerning the Australian crickets was published in 1983 by Otte & Alexander, but this territory still harbors many undiscovered, undescribed treasures. Both existing species of Australian Lebinthus prove to belong to the tribe Eurepini. Our study results in the following new combinations: Salmanites miripara (Otte & Alexander, 1983) n. comb. and Eurepa bifasciata (Chopard, 1951) n. comb. In the meantime, newly collected

INTRODUCTION

The crickets of the tribe Lebinthini (subfamily Eneopterinae) are mainly distributed in Southeast Asia and in the archipelagos of the Western Pacific. Most of the brachypterous Lebinthini form a monophyletic group corresponding to genera diversified both morphologically and acoustically [START_REF] Robillard | The brachypterous Lebinthini crickets from Papua New Guinea, with description of two new genera and four new species (Orthoptera: Gryllidae: Eneopterinae)[END_REF], and being more or less related to the genus Lebinthus Stål, 1877, as suggested by recent phylogenetic studies [START_REF] Nattier | Older than New Caledonia emergence? A molecular phylogenetic study of the eneopterine crickets (Orthoptera: Grylloidea)[END_REF][START_REF] Anso | Old Lineage on an Old Island: Pixibinthus, a new cricket genus endemic to New Caledonia shed light on gryllid diversification in a hotspot of biodiversity[END_REF][START_REF] Vicente | In and out of the Neotropics: historical biogeography of Eneopterinae crickets[END_REF]. Most of these genera have been recently described from New Guinea [START_REF] Robillard | Centuriarus n. gen., a new genus of Eneopterinae crickets from Papua (Insecta, Orthoptera, Grylloidea)[END_REF][START_REF] Vicente | Gnominthus gen. nov., a new genus of crickets endemic to Papua New Guinea with novel acoustic and behavioral diversity (Insecta, Orthoptera, Gryllidae, Eneopterinae)[END_REF][START_REF] Robillard | The brachypterous Lebinthini crickets from Papua New Guinea, with description of two new genera and four new species (Orthoptera: Gryllidae: Eneopterinae)[END_REF]) and New Caledonia [START_REF] Anso | Old Lineage on an Old Island: Pixibinthus, a new cricket genus endemic to New Caledonia shed light on gryllid diversification in a hotspot of biodiversity[END_REF]. Until now, the brachypterous Lebinthini were only represented in Australia by two species of the genus Lebinthus, which status has not been questioned, Lebinthus miripara [START_REF] Otte | The Australian crickets[END_REF], and Lebinthus bifasciatus [START_REF] Chopard | A revision of the Australian Grylloidea[END_REF] [START_REF] Otte | The Australian crickets[END_REF]. This lack of diversity could indicate either that this clade did not diversify in Australia, despite favourable climatic conditions, especially in the north of the continent, or that this diversity has not been discovered yet.

In this study, we revise the Australian Lebinthus which consists of two species both of which prove to belong to the tribe Eurepini. We assess material from recent field collections and describe two new lineages of brachypterous Lebinthini from northern Australia: Macrobinthus kutini n. sp., and the new genus Julverninthus with the species Julverninthus rentzi n. sp. and Julverninthus minoris n. sp. We provide information about species distribution, illustrate male and female genitalia, forewing venation and habitats.

MATERIAL AND METHODS

Material examined

Specimens studied herein were deposited in Australian National Insect Collection, CSIRO, Canberra, Australia (ANIC), with paratypes deposited in the Muséum national d'Histoire naturelle, Paris, France (MNHN). Square brackets in lists of materials are used for additional information not mentioned on specimen labels.

Observations and morphological analysis

Descriptions were made according to the standards of recent publications concerning new species of Lebinthini genera (e.g., [START_REF] Vicente | Gnominthus gen. nov., a new genus of crickets endemic to Papua New Guinea with novel acoustic and behavioral diversity (Insecta, Orthoptera, Gryllidae, Eneopterinae)[END_REF][START_REF] Robillard | The brachypterous Lebinthini crickets from Papua New Guinea, with description of two new genera and four new species (Orthoptera: Gryllidae: Eneopterinae)[END_REF]. Direct observations and dissections were made using a binocular microscope Leica MZ16 at magnifications up to 115. Male tegminal veins and cells are named after [START_REF] Vicente | Gnominthus gen. nov., a new genus of crickets endemic to Papua New Guinea with novel acoustic and behavioral diversity (Insecta, Orthoptera, Gryllidae, Eneopterinae)[END_REF] and [START_REF] Robillard | Phylogeny and the modalities of acoustic diversification in extant Eneopterinae (Insecta, Orthoptera, Grylloidea, Eneopteridae)[END_REF]. Male and female genitalia have been dissected in softened specimens by cutting the membranes between the paraprocts and the subgenital plate, or between the ovipositor and the subgenital plate, respectively; they have been cleaned with cold KOH and then kept in glycerine in vials pinned under each specimen. Male genitalia are named according to [START_REF] Desutter | Structure et évolution du complexe phallique des Gryllidea (Orthoptera) et classification des genres néotropicaux de Grylloidea.1ère partie[END_REF], modified in [START_REF] Desutter-Grandcolas | Phylogeny and the evolution of acoustic communication in extant Ensifera (Insecta, Orthoptera)[END_REF] and [START_REF] Robillard | Phylogeny and the modalities of acoustic diversification in extant Eneopterinae (Insecta, Orthoptera, Grylloidea, Eneopteridae)[END_REF]. Photographs of male and female genitalia were obtained using an AmScope MU1000 digital camera (www.Amscope.com). Genitalia were stained with a drop of Punktol (JLB, Germany) and photographed in Hand sanitizer [START_REF] Su | A simple and quick method of displaying liquid-preserved morphological structures for microphotography[END_REF]. Abbreviations: see below.

DNA sequencing

Several specimens of a given morphology were analyzed using DNA barcoding to confirm that they belong to the same species. We used a tree-based approach with a maximum likelihood tree reconstructed with the IQ-TREE web service [START_REF] Nguyen | IQ-TREE: A Fast and Effective Stochastic Algorithm for Estimating Maximum-Likelihood Phylogenies[END_REF]. We used a fragment of the small mitochondrial ribosomal subunit (12S rRNA, ~ 400 bp), easy to amplify and which proved to be variable between closely related species in crickets (e.g., [START_REF] Robillard | Phylogeny of the cricket subfamily Eneopterinae (Insecta, Orthoptera, Grylloidea, Eneopteridae) based on four molecular loci and morphology[END_REF][START_REF] Nattier | Secondary Sympatry Caused by Range Expansion Informs on the Dynamics of Microendemism in a Biodiversity Hotspot[END_REF]. Molecular works were performed at the "Service de Systématique Moléculaire" of the MNHN. DNA extractions were made from median legs of crickets using the Epmotion 5075 robot (Eppendorf). All sequences were generated using the amplification and sequencing protocols described in [START_REF] Nattier | Secondary Sympatry Caused by Range Expansion Informs on the Dynamics of Microendemism in a Biodiversity Hotspot[END_REF], with similar primers and annealing temperatures. Newly generated sequences were edited in Sequencher v.4.9 (Gene Codes Co.) and BioEdit v.7.0.5.3 (Hall 1999), blasted with NCBI blast tools and compared; the data will be published as part of a phylogenetic study of the Lebinthini in preparation.

General morphology: FI-II-III, femur of fore, median and hind leg; FW, forewing; HW, hind wing; TI-II-III, tibia of fore, median and hind leg; Tarsomere III-1, III-3: first and third segments of hind leg tarsomere. Discussion. Close examination of the type series revealed that the species belongs to the tribe Eurepini, based on the definition of the eneopterine tribes and the key of [START_REF] Robillard | Phylogenetic systematics of Pseudolebinthus, a new genus of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) from south-east Africa[END_REF]. The following characters were examined to support this transfer: inner tympanum absent, membrane of outer tympanum smooth, male FW venation with CuP extending posteriorly beyond file level, male subgenital plate without swellings on dorsal margin, male genitalia with ramal plates, lateral arms of endophallic sclerite directly prolonged by sclerotization of ectophallic fold.

The attribution of the species to one of the five genera currently included in the tribe Eurepini is more speculative. Based on head morphology with fastigium three times as wide as scape, it could belong to either Salmanites or Eurepella and differs from Eurepa and Myara. The general shape of male genitalia excludes Myara and Eurepa, but could correspond to Salmanites, Arilpa and Eurepella. Finally, there are strong setae oriented anteriorly on dorsolateral margins of pseudepiphallus, which is a characteristic of Salmanites and Arilpa [START_REF] Robillard | Phylogeny and the modalities of acoustic diversification in extant Eneopterinae (Insecta, Orthoptera, Grylloidea, Eneopteridae)[END_REF]. Male FW venation reveals that mirror is entirely absent, which is the only recorded case in Eurepini (even the short winged species in Arilpa and Salmanites possess a mirror cell) [START_REF] Otte | The Australian crickets[END_REF] 31S 132.22E, 6.xii.1967, 1♂; 5.xii.1967, 1♀, W.J.M.

Rentz stop 56 (ANIC Database NO.14-008558, 14-008661, 14-008662) (ANIC) Discussion. Close examination of the type series revealed that this species also belongs to the tribe Eurepini, based on the definition of the eneopterine tribes and the key of [START_REF] Robillard | Phylogenetic systematics of Pseudolebinthus, a new genus of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) from south-east Africa[END_REF]. The following characters were examined to support this transfer as for L. miripara: inner tympanum absent, membrane of outer tympanum smooth, male FW venation with CuP extending posteriorly beyond file level, male subgenital plate without swellings on dorsal margin; male genitalia with ramal plates, lateral arms of endophallic sclerite directly prolonged by sclerotization of ectophallic fold, female apex of ventral valve of ovipositor entirely covered by dorsal valves; female apex of ventral valve of ovipositor entirely covered by dorsal valves. In addition, the epistomal suture on face is interrupted between the tentorial insertions, with a transversal furrow underlying the median ocellus, which is only found in Eurepini genera.

As for the previous species, the attribution of the species to one of the five Eurepini genera is very speculative. Male FW venation with a small mirror, not rounded, points toward Salmanites and Arilpa. The female type has no wings [START_REF] Chopard | A revision of the Australian Grylloidea[END_REF]Figs. 3A ,B,E).

However female non-type specimens all show wings reaching abdomen mid-length (Fig. 3F), which may indicate that the species is winged but that Chopard's allotype lost its wings; it remains compatible with Salmanites and some Eurepa species, which include winged and almost apterous species [START_REF] Otte | The Australian crickets[END_REF].The large size of the ovipositor (2.5 longer than FIII) would exclude Eurepella and Arilpa, and is compatible with Eurepa and Myara. The general shape of the male genitalia and in particular the shape of the pseudepiphallic parameres with anterior projections is, however, clearly a characteristic of Eurepa. In conclusion, the species could either correspond to a new genus, given the original combination of characters, or to a very diverging species of Eurepa or Salmanites. In a conservative way, we consider the species as Eurepa bifasciata n. comb., but this hypothesis will have to be tested in a forthcoming revision of the Eurepini genera and with molecular evidence.

Tribe Lebinthini Robillard, 2004

Julverninthus n. gen. 9A,(11)(12)(13)18) Type species. Julverninthus rentzi, here designated.

Etymology. Genus named after Lebinthus and the prefix "Julvern" corresponding to the contraction of Jules Vernes . This famous French author wrote many adventure novels, among which "Around the world in eighty days". Given that Eneopterinae have travelled around the world after originating from Australia-Antarctica ca. 80 Ma [START_REF] Vicente | In and out of the Neotropics: historical biogeography of Eneopterinae crickets[END_REF], it is an appropriate name for the first endemic genus "coming back" to Australia.

Discussion

In this study, we transferred the two existing species of Australian brachypterous Lebinthini to the tribe Eurepini (Lebinthus miripara and L. bifasciatus), based on reanalysis of the type material and their morphological features. These results suggest that the taxonomy and classification of the Eurepini should be revised using modern tools and standards for systematics.

We also described two new lineages of true Lebinthini from the north of Queensland (Fig. 18). One species, Macrobinthus kutini, belongs to the genus Macrobinthus recently described from New Guinea [START_REF] Robillard | The brachypterous Lebinthini crickets from Papua New Guinea, with description of two new genera and four new species (Orthoptera: Gryllidae: Eneopterinae)[END_REF]. This finding is little surprising, since New Guinea and the north of Australia share a similar climate and are close together in terms of distance. It, however, represents the first exchange of species between the two territories documented amongst the brachypterous Lebinthini (the widely distributed species

Cardiodactylus novaeguineae is widespread it the Western Pacific region, possibly because of its flight abilities and/or its coastal habitat; see [START_REF] Robillard | Redescription of two Cardiodactylus species (Orthoptera, Grylloidea, Eneopterinae): the supposedly well-known C. novaeguineae (Haan, 1842), and the semi-forgotten C. guttulus (Matsumura, 1913) from Japan[END_REF]. The genus Macrobinthus is thus not endemic to New Guinea and surrounding islands, but also occurs in Australia. This likely corresponds to a recent colonization through the Torres Strait.

The second new lineage corresponds to the new genus Julverninthus. It represents original combinations of morphological characters, including puzzling similarities with the male genitalia of the genus Pixibinthus from New Caledonia. The current know distribution of Julverninthus is very limited and will need to be completed by further explorations of the Australian fauna to test whether is it restricted to a small area in Queensland or is wider. Such information will be necessary to discuss the origin of this lineage in Australia in respect to the other lineages of brachypterous Lebinthini present in New Guinea, New Caledonia and Vanuatu. Similarly, acoustic data will be needed to complement the knowledge on these new Australian taxa. Do they conform to the other Lebinthini in terms of system of communication, using high-frequency calls and female vibratory responses (after Hofstede et al. 2015), or do they correspond to a subsequent diversification of the tribe? Each new lineage of Lebinthini discovered during the last decade has indeed added new pieces to help understanding the diversity of eneopterine crickets and their communication systems. 13.9

  Lebinthini genera, Julverninthus is characterized by its setose, trapezoidal fastigium, almost as long as wide, forming a wide rostrum. Eyes smaller and less prominent than in Lebinthus and Macrobinthus, but larger than in Centuriarus and Agnotecous. The genus mostly resembles Macrobinthus in size and general shape, but differs by its very short wings resembling that of Microbinthus in both sexes. Male. FWs very short, dorsal field longer than lateral field (almost of similar size in Lebinthus and Macrobinthus). Harp forming an equilateral triangle, with one main bisinuated oblique vein; posterior edge of harp almost flat along diagonal vein. 1A vein slightly bisinuate anterior to angle, as in Ligypterus, Gnominthus and Cardiodactylus, differing from most brachypterous genera. Mirror little differentiated, cell d1 rectangular. Cell c1 large, trapezoidal, with variable accessory veins. Chord veins delimiting a narrow, semi-circular cell. Apical field very short, including only a small area posterior to mirror with reticulated veins and no cell alignment. Median fold well developed, located on dorsum. Sc vein with 1-2 projections. Male genitalia elongate, characterized by absence of individualized apical lophi, with a long median process, as in Pixibinthus and Macrobinthus wilhelmsis and some species of Agnotecous. Female. FWs very short, barely reaching posterior margin of first sternite, well separated, rounded posteriorly. Ovipositor shorter than FIII, its apex acute, slightly denticulate on dorsal edge. Female copulatory papilla rounded, almost entirely membranous; apex rounded, generally folded ventrally.

Median fold welldeveloped, triangular, located on dorsum. M strong and convex, fused to R near FW apex; Sc with 1-2 projections. Subgenital plate clog-shaped, slightly indented apically; inner side of subgenital plate with lateral swellings. Male genitalia: Pseudepiphallus triangular, elongate, basal margin straight, posterior apex elongate, without paired lophi and forming a gutter, setose ventrally (Figs. 8,13). Rami straight, parallel and short. Ventral pseudepiphallic plate wide. Pseudepiphallic parameres sclerotized, convergent, their basis strong, with two posterior lobes, one oriented dorsally and one forming a rounded ventral plate, and a small basal lobe mostly membranous. Ectophallic apodemes parallel and long, their apex lamellate. Ectophallic arc wide, well sclerotized, with a short medioposterior expansion. Ectophallic fold long, with elongate lateral sclerites forming a ")(" pattern; its apex triangular and membranous. Endophallic sclerite large, comprising posteriorly a short median expansion and lateral arms; sclerite very long anteriorly, Y-shaped, exceeding pseudepiphallic sclerite. Endophallic apodeme with welldeveloped lateral lamellas and a narrow dorsal crest. Female. FWs very short, barely reaching posterior margin of first sternite, well separated from each other, rounded posteriorly; dorsal field with more or less distinct longitudinal veins; lateral field with longitudinal veins curved dorsally. Ovipositor shorter than FIII, its apex acute, slightly denticulate on dorsal edge.

  . Female ovipositor as long as FIII, points toward Eurepa, Myara or Salmanites. In conclusion, the species could either correspond to a new genus, given the original combination of characters, or to a very diverging species of Salmanites. In a conservative way, we considered it as Salmanites miripara n. comb., but this hypothesis will have to be tested in forthcoming revisions of the Eurepini genera and with molecular evidence.
