Taxonomic work on the land snail genus Sarika Godwin-Austen, 1907 in Cambodia is scarce. A total of three species were recognized from Cambodia prior to this study. However, their taxonomic descriptions were based mainly on shell morphology, with limited genital data. To address this knowledge gap, we opportunistically surveyed for land snails in Cambodia. Our inventory yielded four species of Sarika – one recognized species, Sarika bocourti (Morelet, 1875), from Battambang Province and three new species, Sarika khmeriana Pholyotha & Panha sp. nov., Sarika lactoconcha Pholyotha & Panha sp. nov. and Sarika nana Pholyotha & Panha sp. nov. from Kampot and Takeo Provinces in southern Cambodia. Our discovery involves the first species of Sarika to be described from Cambodia in more than a century highlights the extent to which the diversity of Cambodian land snails remains to be discovered. The status of two species, Sarika benoiti (Crosse & Fischer, 1863) and Sarika resplendens (Philippi, 1846), is at present ambiguous because no material identifiable as these species was found in recent extensive surveys. Although S. bocourti was recently collected from Cambodia, its taxonomic position remained unclear due to a lack of living specimens. Detailed descriptions and illustrations of living animals, shell morphology and reproductive anatomy are provided, and a map showing their distributions is given.
Small usually beautifully coloured mussels from the Kattegat were to date identified as Modiolus adriaticus (Lamarck, 1819) since C.G.Johs. Petersen’s account of the shell-bearing molluscs was published in 1888. However, these mussels from Danish and Swedish waters represent a very distinct new species which also is endemic. The present paper serves to describe this new species, Modiolus cimbricus sp. nov., which belongs to the genus Modiolus Lamarck, 1799. The genus Gibbomodiola Sacco, 1898, to which Modiolus adriaticus has been moved, is here synonymized with Modiolus Lamarck, 1799.
The ‘gigas’ group of dragon millipedes, formerly placed in the genus Desmoxytes Chamberlin, 1923, is revised and assigned to the new genus Gigaxytes gen. nov. Desmoxytes gigas Golovatch & Enghoff, 1994 is the type species of the new genus and is redescribed as G. gigas (Golovatch & Enghoff, 1994) gen. et comb nov. Three new species are described: G. fusca gen et sp. nov. from Thailand and Myanmar; G. parvoterga gen et sp. nov. and G. suratensis gen et sp. nov. from Thailand. All Gigaxytes species are endemic to small distribution areas in limestone habitats in South Thailand and South Myanmar. Illustrations of external morphological characters and an identification key to all known species are provided as well as a distribution map.
Description of three new species of Caledomina (Insecta, Trichoptera, Ecnomidae) from New Caledonia
(2017)
Three new species of Caledomina Johanson, 2011 are described and illustrated for the first time: C. paniensis sp. nov., C. dorsospina sp. nov. and C. kohensis sp. nov. A key to the males of the four known species in the genus is given, as well as a map indicating their geographical distribution. When examining a phylogenetic hypothesis comprising the four species, we see an increased complexity in younger species compared to older species.
In 2005 we started a study of the ecology and evolutionary history of damselflies of the genus Nesobasis, endemic to Fiji. In addition we made account of the species of Zygoptera present at our study sites, and made notes on the Anisoptera. In general, the odonate fauna of the Fiji archipelago is poorly studied. Here, we provide an historical overview of the knowledge on this fauna and give details of the species we encountered in August - September 2005. We made observations and collected voucher specimens for 2 species of the genus Ischnura, 2 of the genus Agriocnemis, 1 of the genus Austrolestes, 7 of the genus Melanesobasis and 25 of the genus Nesobasis. For Melanesobasis we also made account of an additional subspecies. Further, we discovered 2 species of damselfly new to science, 1 on Viti Levu and 1 on Vanua Levu, both belonging to the genus Nesobasis. Our results indicate that further exploration within the Fiji archipelago will be rewarding and that more species new to science are to be discovered. We hope our work will spur further interest in the Pacific, which will be essential if we are to conserve the unique community of damselflies encountered in this region.
Records of 33 species of Odonata from Ankarafantsika National Park are presented. Four additional species have been reported in the literature. Nineteen species are recorded from the site for the first time. The site is the largest remaining block of dry forest in Madagascar’s Western Region. While 80% of Madagascar Odonata species are endemic, only 40% of the species recorded in Ankarafantsika is endemic. Moreover, the endemics recorded are mostly common throughout the island. The dry forests are thus of relatively little importance for Madagascar’s diversity of Odonata.
