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 the Galapagos, while the distantly related blind L. gertschi is found only on Jamaica.

The Mexican genera Tivodrassus and Tricongius have been suggested as sister groups of Lygromma.

Species can reach a body length from about 2 to 4.6 mm.
