Borkent, Art.2005-10-062005-10-062001http://hdl.handle.net/2246/294511 p. : ill. ; 26 cm.Includes bibliographical references (p. 11).As predicted by phylogenetic patterns, the genus Leptoconops Skuse is recorded for the first time from Lower Cretaceous Lebanese amber, dated at 120-122 million years. Two species are described as new: L. amplificatus, known from 1 male and 11 females, and L. antiquus, known from 2 females. These likely represent the earliest lineage(s) within the genus and are placed in a new subgenus, Palaeoconops. Previous analysis of Lebanese amber Ceratopogonidae (22 species, 126 specimens) indicated that these specimens represent a past community with high species diversity but with a low abundance of individual species. Leptoconops amplificatus is the first of 24 species of Ceratopogonidae known from this deposit to have intraspecific associations in a single piece of amber, likely reflecting their restriction to ancient beach habitats.6059898 bytesapplication/pdfen-USQL1 .A436 no.3328 2001Leptoconops amplificatus.Leptoconops antiquus.Palaeoconops.Ceratopogonidae, Fossil -- Lebanon.Amber fossils -- Lebanon.Insects, Fossil -- Lebanon.Paleontology -- Cretaceous -- Lebanon.Paleontology -- Lebanon.text
