L. argyrobapta is found from the south of the USA (mainly Florida), all the way to Brazil.

[3] Adam White first described the Leucauge at the rank of subgenus, and the described the type species, then being Linyphia argyrobapta.

This species was collected by Charles Darwin in 1832, in the Rio de Janeiro area.

And those of Florida and Brazil had a low genetic distance, even though the large geographic difference.

[3] The specific name is from Ancient Greek βάπτω (baptō, "to dip") and ἄργῠρος (argyros, "silver"), so called because the spider appears to have been "dipped" in silvery paint.
