Abstract: This paper is a systematic report and a biological analysis of the Mesoveliidae from Hawaiian caves. Most important is a new species of Speovelia Esaki, S. sp. (Hawaii I.), described from material collected on moist walls in lava tubes. This apparently represents the world's first troglobitic heteropteran. Morphologically, all instars show lack of pigmentation, functionless eyes and prolongation of the appendages and head. Biologically, it is restricted to the dark zone of lava tubes. Notes on its biology are given. It also represents the first known endemic species of the family for the Hawaiian Islands. Another species, Mesovelia amoena Uhler, is troglophilic. This is the first record of this immigrant American species in the Hawaiian Islands. The remaining species in Hawaii, the immigrant M. mulsanti White, has only been found in epigean situations. A key to the species is also presented.
Description: Reports were scanned in black and white at a resolution of 600 dots per inch and were converted to text using Adobe Paper Capture Plug-in.
Sponsor: We are especially indebted to Dr. Hiroshi Hashimoto of Shisuoka University, Japan for locating and providing us with specimens of Speovelia maritima Esaki for comparative purposes. He also sent notes on its biology in the laboratory observed by Drs. Tokunaga and Aoki. Mr. John Polhemus of Englewood, Colorado confirmed the identity of M. amoena and sent comparative notes on S. sp. from his Mesoveliidae of the World project. His brother, Martin also kindly furnished locality data on M. amoena on Oahu. We are also especially indebted to our artists, Allan Hart, Entomology Department, Bishop Museum and Charles Bretz, Botany Department, University of Hawaii. Dr. R. H. Cobben, Landbonwhogeschool, Wageningen, the Netherlands and Mr. John Polhemus reviewed the manuscript. Bobbie Myers Linda Miyasaki, George-Ann Davis, Betsy Harrison, Nancy Howarth typed various drafts of the manuscript, for which we are grateful.
