[2] The species was originally classified as a part of the genus Myrmarachne in 1933 by Saitō in his work Notes on the spiders from Formosa, but it was later reclassified as Toxeus by the Polish arachnologist Jerzy Prószyński in November 2016.

[4] The white milk-like nutritional fluids produced by the female Toxeus magnus contains sugar, fat, and protein.

[6] Researchers attempted to discover how long the Toxeus magnus spiderlings can survive without their mother's "milk" by glueing her epigastric furrow shut.

[4] While the mother might occasionally hunt for fruit flies and other small insects to eat herself, they are not known to return prey back to the nest for feeding their offspring and it is believed that baby Toxeus magnus exclusively feed off of the milk-like substance produced by their mothers for the first three weeks of their lives before they start foraging themselves.

[4] After reaching sexual maturity, daughters (but not sons) are allowed to continue, while at this stage in their lives the continued consumption of this milk-like fluid is not exclusively necessary for survival the offspring that consume it have higher chances of survival, since foraging outside their nest would increase the risk of predation.
