Lygromma Peckorum
''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 — Colo ...

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 h ...

Spiders Of Central America
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separat ...

Prodidominae
Prodidominae is a family of spider, sometimes called long-spinneret ground spiders. It was formerly regarded as a subfamily of Gnaphosidae, but was raised to a family in 2022. Spiders in the family are easily identified by the greatly elongated base of the piriform gland spigots. At least parts of their body are covered with shiny scales or setae. The posterior median eyes are flat and silvery, with a triangular, egg-shaped or irregularly rectangular shape.Barbara BaehrProdidomidae/ref> Biology Spiders in the Prodidominae are ground dwellers. Most species are nocturnal and hide during the day in litter, but ''Myandra'' species, which are probably mimicking ants, seem to be active during the day. The genus ''Zimiris'' is synanthropic and thus found throughout the tropics. Distribution Although ''Theuma walteri'' was described from Turkmenistan by Eugène Simon, it is suspected that Simon accidentally exchanged its locality with that of ''Anagraphis pallens'' (Gnaphosidae); the ...
