Revision of the genus ogygioses (Palaeosetidae)

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

The systematics and external morphology of the oriental genus Ogygioses are reviewed. Monophyly of the genus is demonstrated by the two segmented labial palpi, loss of the jugal lobe in the forewing, stalking of the forewing R4 with the base of R2 + 3 and a specialised scale arrangement on the forewing base. Sculpturing of the egg chorion differs from that of other Exoporia in exhibiting elongate tubercles regularly dispersed over the surface. The genus is retained tentatively in the Paleosetidae on the basis of the loss of all tibia1 spurs, including the epiphysis, and the extreme reduction of the maxillae. Four species are recognised: O. caliginosa Issiki & Stringer, O. eurata Issiki & Stringer, O. issikii Davis, sp. nov., from Taiwan, and O luangensis Kristensen, sp. nov., from Thailand. Adults are diurnal with the males forming hovering groups, or leks, similar to some species of Hepialidae.

D. R. Davis extends his deepest gratitude to the late Professor Syuti Issiki, formerly of the National Taiwan University at Taipei, Taiwan, and later of the faculty of Agriculture at the Osaka Prefecture University, Japan. The Issiki Microlepidoptera Collection, now deposited in the Smithsonian Institution (Davis 1973), contains many specimens of Ogygioses collected by Issiki during his 28 years of residency in Taiwan. Field work of D. R. D. in Taiwan was supported by a grant from the Smithsonian Institution Fluid Research Fund. D. R. D. is also grateful to Shui-chen (Sally) Chiu, formerly of the Taiwan Agricultural Research Institute (TARI), Sheng-hwa Lin Chow of the National Science Council of the Republic of China, Yau-i Chu of the National Taiwan University at Taipei, Ming-jou Lai of the Taiwan Natural History Museum in Taipei, and Jen-ren Shih for assisting with travel arrangements in Taiwan. John Heppner of the Florida State Collection of Arthropods was helpful in lending specimens collected during his survey of the Lepidoptera of Taiwan. Tosiro Yasuda of the University of Osaka, Japan, graciously presented study material. Field work by 0. K. in Thailand is part of a collecting programme sponsored by the Zoological Museum, University of Copenhagen. He is indebted to Mr Nipond Sornnakorn, head of the Phu Luang Wildlife Sanctuary, for his hospitality and guidance in the sanctuary. Special thanks are extended to Kyoichiro Ueda of the Kitakyushu Museum of Natural History, Kitakyushu, Japan, for providing us with a summary of his observations on adult Ogygioses caliginosa. We are indebted to Susann Braden, Walt Brown and the late Bent W. Rasmussen of our Scanning Electron Microscope Laboratories and to Geert Brovad and Victor Krantz of our Photographic Laboratories for their photographic assistance. Artwork was prepared by Vichai Malikul, Biruta Akerbergs Hansen and Robert Nielsen. Finally, we acknowledge the cooperation of the following institutions: ANIC, BMNH, FSCA, KMNH, TPM, USNM and ZMUC.
