'''''Lygromma anops''''' is one of only three known eyeless spiders in the superfamily [[Gnaphosoidea]], and one of only two known [[troglobite]]s (cave species). It is found in [[lava]] caves on [[Santa Cruz Island (Galápagos)|Isla Santa Cruz]], [[Galápagos]].
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 ''[[Lygromma senoculatum|L. senoculatum]]'', ''[[Lygromma valencianum|L. valencianum]]'' and ''[[Lygromma huberti|L. huberti]]'' from [[Venezuela]].
''[[Lygromma gertschi]]'', a blind, cave-inhabiting species from [[Jamaica]] is not a close relative of ''L. anops''.
