- This species has previously been placed in the family Amaurobiidae and, before that, in the family Dictynidae. It was transferred to Amphinectidae by Valerie Davis in 1998.
- Based on general appearance, can be mistaken for spiders in the family Amaurobiidae. If you have a microscope: Metaltella simoni is the only known cribellate species in North America with 5 or more teeth on both the pro- and retromargin of the chelicerae (Leech 1971, Leech 1972, Cutler 2005).
- In the state of California, this species was one of the five most common spiders to be misidentified by the general public as a “brown recluse” and submitted to Rick Vetter at U.C. Riverside (Vetter 2005).
- The anterior (front) portion of the carapace, near the eyes, is usually darker than the rest of the carapace.
- Often has some pale chevron-like markings running the length of the abdomen, but these markings may be indistinct or lacking, especially in older specimens.
- Egg sacs are globular and usually suspended within the web and covered with sand, dirt, or other debris the female finds nearby.
