''Lygromma'' is a spider genus of Central and South America. There are species with eight, six (e.g. ''L. senoculatum'', ''L. valencianum'') and no eyes. The eyeless ''L. anops'' is endemic to Galapagos, while the not closely related blind ''L. gertschi'' is found only on Jamaica. The Mexican genus '' Tivodrassus'', and '' Tricongius'' have been suggested as sister groups of ''Lygromma''. Species reach a body length from about 2 to 4.6 mm. Species it contains 19 species: * '' Lygromma anops'' Peck & Shear, 1987 — Galapagos Islands * '' Lygromma chamberlini'' Gertsch, 1941 — Panama, Colombia, Cuba * ''Lygromma domingo'' Platnick & Shadab, 1981 — Ecuador * ''Lygromma dybasi'' Platnick & Shadab, 1976 — Costa Rica, Panama * ''Lygromma gasnieri'' Brescovit & Höfer, 1993 — Brazil * ''Lygromma gertschi'' Platnick & Shadab, 1976 — Jamaica * ''Lygromma huberti'' Platnick & Shadab, 1976 — Venezuela, Brazil * ''Lygromma kochalkai'' Platnick & Shadab, 1976 — Colombia ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...
