TL;DR: This study redescribes or append their taxonomic features using external morphological features and internal genitalic structures and updates the list of Xenogryllus by describing three new spe.
Abstract: Subfamily Eneopterinae has been studied for its diversified acoustic modalities and disjunct distribution. The genus Xenogryllus Bolivar, 1890 is one of the oldest genera of the subfamily, and the first genus of the tribe Xenogryllini. Xenogryllus is known for its low-frequency calling songs and wide distribution across Africa and Asia. It is known from six species and has never been subject to formal taxonomic revision and description of acoustic features of their calling songs is lacking. Therefore, this study consists of a detailed taxonomic revision of all the species. We redescribe or append their taxonomic features using external morphological features and internal genitalic structures. We update the list of Xenogryllus by describing three new species from Africa. In addition, we provide keys to identify species and describe the calling songs of five species.
TL;DR: Two new lineages of brachypterous Lebinthini from northern Australia are described, one of which belongs to the tribe Eurepini and the other to the new genus Julverninthus.
Abstract: 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 material from northern Queensland allows us to describe two new lineages of brachypterous Lebinthini from northern Australia, the species Macrobinthus kutini n. sp., and the new genus Julverninthus and the species Julverninthus rentzi n. sp. and Julverninthus minoris n. sp.
TL;DR: This study adds a new species to the genus Pseudolebinthus, P. gorochovi Robillard sp.
Abstract: Pseudolebinthus is an intriguing genus of the tribe Xenogryllini with a distribtuion restricted to southeast Africa and characterized by unique morphological features such as asymmetrical male forewings and harp veins shaped as elongated balloons. It is sister group to the widely distributed genus Xenogryllus and has been known by two species, P. africanus Robillard, 2006 and P. whellani Robillard, 2006. The genus was initially diagnosed based exclusively on male morphological features. In this study, we add a new species to the genus, P. gorochovi Robillard sp. nov. and revise the diagnostic features using both male and female characters. We also update identification keys for the species of the genus.
TL;DR: The genus Paranisitra Chopard (Orthoptera: Gryllidae: Eneopterinae: Nisitrini) is reviewed and a new species is described from Mindanao.
Abstract: The genus Paranisitra Chopard (Orthoptera: Gryllidae: Eneopterinae: Nisitrini) is reviewed. New records and additional descriptions are provided for P. longipes Chopard, P. leytensis Robillard, and P. septentria Baroga, Yap & Robillard, and a new species is described from Mindanao: Paranisitra flavofacia n. sp. A taxonomic key and updated checklist of the genus Paranisitra in the world are also provided.
TL;DR: Based on a recent orthopteran survey in Sandakan, one new species of Le binthus Stål is described: Lebinthus sandakan sp.
Abstract: Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stal is described: Lebinthus sandakan sp. nov. The male calling song of this new species is also presented. The calling song of Cardiodactylus borneoe Robillard & Gorochov, 2014 is also described for the first time.
