As of September 2025[update] the genus contains three species:[1]
- Admestina archboldi Piel, 1992 — United States
- Admestina tibialis (C. L. Koch, 1846) — United States
- Admestina wheeleri Peckham & Peckham, 1888 — United States, Canada
The South American species Admesturius bitaeniatus was originally placed in Admestina, but was moved to Admesturius by María Elena Galiano in 1988.[1]
Description
Admestina are small and flat, typically measuring less than 4.5 mm in length. Their flattened cephalothorax may help them to hide within crevices on trees. The first legs are the stoutest, with the tibia thickened in both sexes. The three species are all similar in appearance and best distinguished by their geographic range and genitalia.[3]
Distribution
Admestina archboldi is found in the Southern United States, from Florida to Texas, generally between the 30th and 25th parallels. Admestina wheeleri is found in the Northern United States, from Massachusetts to North Dakota, and in Ontario, Canada. Its range roughly follows the 45th parallel. Admestina tibialis is found in the area in between, from Florida to Connecticut.[3]
