Species of spider

Lygromma anops Scientific classification Kingdom: Animalia Phylum: Arthropoda Subphylum: Chelicerata Class: Arachnida Order: Araneae Infraorder: Araneomorphae Family: Prodidomidae Genus: Lygromma Species: L. anops Binomial name Lygromma anops Peck & Shear, 1987[1]

***Lygromma anops*** is one of only three known eyeless spiders in the superfamily [Gnaphosoidea](/source/Gnaphosoidea), and one of only two known [troglobites](/source/Troglobite) (cave species). It is found in [lava](/source/Lava) caves on [Isla Santa Cruz](/source/Santa_Cruz_Island_(Gal%C3%A1pagos)), [Galápagos](/source/Gal%C3%A1pagos).

It is possible that *L. anops*, like many inhabitants of lava caves, colonizes new caves through interconnecting cracks and crevices, and that these small spaces are in reality its main habitat.

Males reach a body length of about 3.4 mm.

*L. anops* seems to be closely related with *[L. senoculatum](https://en.wikipedia.org/w/index.php?title=Lygromma_senoculatum&action=edit&redlink=1)*, *[L. valencianum](https://en.wikipedia.org/w/index.php?title=Lygromma_valencianum&action=edit&redlink=1)* and *[L. huberti](https://en.wikipedia.org/w/index.php?title=Lygromma_huberti&action=edit&redlink=1)* from [Venezuela](/source/Venezuela).

*[Lygromma gertschi](https://en.wikipedia.org/w/index.php?title=Lygromma_gertschi&action=edit&redlink=1)*, a blind, cave-inhabiting species from [Jamaica](/source/Jamaica) is not a close relative of *L. anops*.
