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.

- General appearance almost the same as in the introduced species Cheiracanthium mildei; the two should be separated only by microscope exam.
- More commonly found outdoors, whereas the introduced species Cheiracanthium mildei is more common indoors.
- Cheiracanthium species are sometimes mistaken for “brown recluses” (Loxosceles reclusa) inside homes.
