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

Phylogeny, systematics and evolution of calling songs of the Lebinthini crickets (Orthoptera, Grylloidea, Eneopterinae), with description of two new genera

“…This clade has been recognized as a taxonomic group in previous studies and has been referred to as ‘brachypterous Lebinthini’ or as the ‘ Agnotecous‐Lebinthus ’ clade (Robillard et al ., 2007, 2013, 2016). Until 2011, this group only included a few species from the genera Agnotecous and Lebinthus , but recent taxonomic revisions and field work have revealed an unsuspected diversity resulting in the discovery and description of many new genera and species from Australia (Robillard & Su, 2018), New Guinea (Robillard, 2011a; Vicente et al ., 2015; Robillard et al ., 2016), New Caledonia (Anso et al ., 2016), and Southeast Asian archipelagos (this study). Interestingly, this subtribe is the sister group to Cardiodactylina with which it shares more or less the same distribution (Fig.…”

“…– Male FWs with harp area forming an equilateral triangle; female FWs very small <2.0 mm, never overlapping with each other, without striking cross veins … Julverninthus Robillard & Su, 2018.…”

“…These newly described taxa are thought to be related to the genus Lebinthus Stål, which appeared as a paraphyletic assemblage in several phylogenetic studies (Nattier et al 2011;Anso et al 2016). To clarify the taxonomy of this clade, several new genera were recently described from New Guinea [Centuriarus Robillard (Robillard, 2011a), Gnominthus Robillard & Vicente (Vicente et al, 2015), Microbinthus Robillard & Dong, Macrobinthus Robillard & Dong (Robillard et al, 2016)]), New Caledonia [Pixibinthus Robillard & Anso (Anso et al, 2016)], and Australia [Julverninthus Robillard & Su (Robillard & Su, 2018)]. These descriptions distinguished clear morphological entities and made Lebinthus monophyletic in the most recent phylogenetic study (Vicente et al, 2017).…”

Phylogenetic relationships in the cricket tribe Xenogryllini (Orthoptera, Gryllidae, Eneopterinae) and description of the Indian genusIndigryllusgen. nov.

“…The species ratio Lebinthini/Xenogryllini was 34/7 in 2004, but the recent taxonomic discoveries in both clades changed drastically this ratio: With a similar taxonomic treatment, the Xenogryllini now includes a total of 12 species under three genera, whereas the Lebinthini include ca. 150 species under 12 genera (e.g., Robillard et al, ; Vicente, Olivero, Lafond, Dong, & Robillard, ; Anso et al, ; Robillard, Dong, Legendre, & Agauvoa, ; Robillard & Su, ), and many Lebinthini taxa yet remain undescribed (T. Robillard, personal communications). This contrast is corroborating the hypothesis that the Lebinthini were likely subject to a taxonomic radiation, possibly in relation with their innovations in terms of communication system (Robillard, Grandcolas, & Desuter‐Grandcolas, ).…”

Rugabinthus, a new genus of Lebinthina (Orthoptera, Gryllidae, Eneopterinae) from New Guinea

“…However, as new information about these species became available, their classification has been more accurately revised (Tan et al 2021) and the subtribe Lebinthina Robillard & Tan, 2021 has been defined. Multiple new genera have also been erected, including Centuriarus Robillard, 2011 (Robillard 2011), Gnominthus Robillard & Vicente, 2015(Vicente et al 2015, Microbinthus , and Macrobinthus Robillard & Dong, 2016(Robillard et al 2016) from New Guinea; Pixibinthus Robillard & Anso, 2016 from New Caledonia (Anso et al 2016); Falcerminthus Robillard &Tan, 2021 andFadinthus Robillard &Tan, 2021 from Southeast Asia (Tan et al 2021); and Julverninthus Robillard & Su, 2018 from Australia (Robillard and Su 2018). These studies revealed that most Lebinthus species known before 2010 corresponded to distinct genera, and that the island of New Guinea possesses the highest diversity of genera and species of the Lebinthina clade (Tan et al 2021, Tan andRobillard 2021c).…”
