New species of Phaloria (Orthoptera: Phalangopsidae: Phaloriinae) from West Papua (Indonesia).

The genus Phaloria belongs to the monophyletic cricket subfamily Phaloriinae. It is s speciose group comprising 68 species found across Southeast Asia and New Guinea and Australia. The numerical diversity of Phaloria in New Guinea is impressive, but more species still await discovery owing to the large size and remoteness of the island.

A new species of Heminicsara (Orthoptera: Tettigoniidae: Agraeciini) from West Papua (New Guinea).

Heminicsara Karny, 1912 is a katydid genus of Agraeciini from the Axylus genus group. It currently comprises 62 species from mainly New Guinea and surrounding archipelagos. Based on recent fieldwork in Lobo in West Papua, Indonesia, a new species of Heminicsara is described here: Heminicsara incrassata sp.

Macroevolution of hyperdiverse flightless beetles reflects the complex geological history of the Sunda Arc.

The Sunda Arc forms an almost continuous chain of islands and thus a potential dispersal corridor between mainland Southeast Asia and Melanesia. However, the Sunda Islands have rather different geological histories, which might have had an important impact on actual dispersal routes and community assembly. Here, we reveal the biogeographical history of hyperdiverse and flightless Trigonopterus weevils.

Ninety-eight new species of Trigonopterus weevils from Sundaland and the Lesser Sunda Islands.

The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterusamphoralis Marshall, 1925 was so far recorded West of Wallace's Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised.

Revision of the cricket genus Cardiodactylus (Orthoptera, Eneopterinae, Lebinthini): the species from both sides of the Wallace line, with description of 25 new species.

The genus Cardiodactylus is the most speciose and widely distributed genus of the cricket subfamily Eneopterinae and of the Lebinthini tribe. Along with diverse acoustic features, this genus is also characterized by a wide distribution area running from Japan to Southeast Asia, Northern Australia and in many archipelagos in the Western Pacific, with a high contrast in species distributions. In this paper we start revising Cardiodactylus by focusing on the western region of its wide distribution and the Novaeguineae species group.
