Identification
Calilena restricta can be distinguished from the related Hololena by : Calilena possesses long spinnerets typically held parallel to each other, whereas Hololena has short spinnerets often directed inward toward each other. It is generally smaller than Agelenopsis, which averages 10–20 mm in body length compared to Calilena's more modest size. Definitive identification to level requires microscopic examination of genitalia and other diagnostic structures.

Similar Taxa
- HololenaBoth are agelenid funnel-web weavers with similar web architecture and general appearance, but Hololena has short, inward-directed versus Calilena's long, parallel spinnerets.
- AgelenopsisSimilar sheet-and-funnel web structure and color pattern, but Agelenopsis averages substantially larger body size (10–20 mm versus smaller Calilena) and also possesses long parallel .
