Steatoda washona
Steatoda washona is a cobweb spider in the family Theridiidae, described by Gertsch in 1960. It belongs to a genus that includes several species commonly known as false widows due to their resemblance to black widows (Latrodectus). The species occurs in the southwestern United States and Mexico. Like other Steatoda species, it constructs irregular tangled webs and is typically found in sheltered microhabitats.
Trogloneta paradoxa
Trogloneta paradoxa is a minute spider species in the family Mysmenidae, first described by Gertsch in 1960. Members of this family are among the smallest spiders known, with body lengths typically under 2 mm. The genus Trogloneta is characterized by a distinctive body shape featuring a disproportionately large, spherical posterior abdomen relative to the cephalothorax. The specific epithet "paradoxa" likely refers to this unusual morphology. The species is known from the United States.
