Leptopharsa tacanae

''Leptopharsa tacanae'' is an extinct species of lace bug in the family Tingidae. The species is solely known from the Late Oligocene to Middle Miocene Mexican amber deposits. The species is the first lace bug described from Mexican amber.
==History and classification==
''Leptopharsa tacanae'' is known from the holotype specimen, collection number TOT158.1, which is an inclusion in a transparent chunk of Mexican amber, also known as Chiapas amber. As of 2014, the type insect was part of the David Coty fossil collection provisionally housed at the Muséum National d’Histoire Naturelle, Paris, France.〔 This amber predates a range from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone, and 26 million years, for the La Quinta Formation. This age range, which straddles the boundary between the Late Oligocene and Early Miocene, is complicated by both formations being secondary deposits for the amber; consequently, the given age range is only the youngest that the fossil might be. The ''L. tacanae'' fossil was recovered from amber deposits along the Yalbantuc River, near Totolapa in the Chiapas depression, distant from the major Mexican amber deposits in the Simojovel region. The geology of the Totolapa region is currently identified as Eocene in age, but the fauna of the amber is very similar to both the Simojovel fauna and to Dominican amber, indicating that a reassessment of the geology may be needed.〔
The holotype was first studied by paleoentomologists David Coty, Romain Garrouste and André Nel, of the Muséum National. Their type description of the species was published in the ''Annales de la Société Entomologique de France (N.S.): International Journal of Entomology'' in 2014. The specific epithet ''tacanae'' derived from the Tacana volcano, which is on the boarder of Mexico and Guatemala, and the second highest volcano in Central America.〔
''Leptopharsa tacana'' is the first lace bug to be described from Mexican amber fossils, while the related Dominican amber fauna is much more diverse with six described species as of 2014: ''Eocader balyrussus'', ''Leptopharsa evsyunini'', ''Leptopharsa frater'', ''Leptopharsa poinari'', ''Stephanitis rozanovi'' and ''Phymacysta stysi''.〔
