Identification Traits

Disclaimer: The following table provides a quick overview of the spider's basic attributes. The physical traits are greatly generalized in order to aid in the identification and sorting of spider species using our search feature. This information is not exhaustive, and keep in mind that traits such as color, markings, and overall size and shape can vary widely within a species due to variables such as the spider's age, gender, diet, hydration level, climate, and habitat. Though experienced arachnologists and hobbyists can often classify spiders rather accurately based on their unique markings and general appearance, it's important to know that scientifically accurate spider identification relies on detailed taxonomic keys and microscopic examinations of a spider's reproductive organs.

Additional Remarks

  • 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 markingsĀ 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.
