Research paper thumbnail of Identification and reproductive isolation of Euborellia species (Insecta, Dermaptera, Anisolabididae) from East and Southeast Asia

To settle the classification of brachypterous species with abbreviated tegmina recorded from East and Southeast Asia, we examined the morphology and reproductive isolation of three tentative Euborellia species, and analyzed the DNA barcoding region of the mitochondrial cytochrome oxidase subunit I (COI) gene. The observed complete reproductive isolation among the three Euborellia taxa and considerable differentiation in the COI sequences clearly show that each should be treated as a separate species. Based on morphology, distribution and the DNA sequence, we identify Euborellia sp. 1 of Malaysia as E. annulata (Fabricius), a circumtropical cosmopolitan with no records of a fully winged form. Samples from Ioto Island (= Iwo-jima Island: Ogasawara Islands, southern Japan) were also identified as this species. Euborellia sp. 3, from ...

Seasonal changes in occurrence and abundance of earwigs were monitored in olive orchards in (Tarsus) Mersin and Erzin (Hatay) for two successive years. Samples were collected by using aspirator, handing, knocking and with twigs plucked from olive trees and separated in the laboratory. Six species from Forficulidae family in altogether 98 specimens were collected. Forficula aetolica Brunner, 1882 (2 specimens), F. auricularia Linnaeus, 1758 (13), F. decipiens Géné, 1832 (1), F. lurida Fischer, 1853 (41), Guanchia brignolii (Vigna Taglianti, 1974) (22), G. hincksi (Burr, 1947) (1), Guanchia sp. (14) and Forficula sp. (4) were determined in olive orchards (Oleae europae L.) in Adana, Hatay, Kahramanmaraş, Mersin, Osmaniye provinces (eastern Mediterrenean region), Gaziantep and Kilis provinces (southeastern Anatolia region) ...

Research paper thumbnail of Notes on the Earwig Family Spongiphoridae(Insecta: Dermaptera), with a New Record ofSpongovostox sakaii in Korea

Animal Systematics, Evolution and Diversity, 2017

The earwig species Spongovostox sakaii Nishikawa, 2006 is reported from the Korean Peninsula for ... more The earwig species Spongovostox sakaii Nishikawa, 2006 is reported from the Korean Peninsula for the first time. The species was originally described from Amami-Oshima, Nansei Islands, Japan, which is located in the Oriental Region. Its distribution in Korea was confirmed by collections from Gwangneung Forest, which is located in the middle of South Korea. This is also first record of the pantropical genus Spongovostox Burr, 1911a from the Palearctic Region. Along with Labia minor Linnaeus, 1758 and Paralabellula curvicauda (Motschulsky, 1863), which had been reported from Korea previously, notes on the species are provided. And a key, descriptions, photos, and illustrations are given for their identification.

Echinosoma roseiventre Kamimura & Nishikawa, sp. n. is described and illustrated, and Cranopygia pallidipennis (de Haan, 1842) is reported from the island for the first time. The taxonomic and nomenclatural problems of the genus Cranopygiasensu Hincks (1959) [A Systematic Monograph of the Dermaptera of the World. Part II. Pygidicranidae excluding Diplatyinae. British Museum (Natural History)] are also discussed. For the members of the subfamily Pygidicraninae from Indo-Austral and Oriental regions, the system, definitions of genera, and key of Hincks (1959) are followed. The genus Mucrocranopygia Steinmann, 1986 is synonymized with Cranopygia Burr, 1908. A key to the males of small Echinosoma from the Oriental region is provided.
