Genus Chileotrecha Maury, 1987

Revised diagnosis: Ammotrechidae with tarsi II and III bi-segmented with 1.2.2/2.2 ventral spines; tarsi IV bisegmented, with pseudo segmentation on basal segment, and 2.2.2-2/2.2 ventral spines. Metatarsus II and III with 1.1.1 retrolaterodorsal and 1.1 retrolateral being intercalated: 1.(1).1.(1).1. Tibia II and III without dorsoapical spines. Pedipalps covered by several truncated tip setae with pore, some clubbed setae and a few very long blunt setae; with short ventral spines (shorter than the width of pedipalp); tarsus immovable or fixed. Chelicerae with three anterior teeth on fixed finger. Female chelicerae with a dorsal hump on fixer finger at level of anterior teeth. Body covered by spiniform setae.

According to our data, Chileotrecha is closely related to Procleobis and Sedna Muma, 1971 . Chileotrecha differs from Procleobis by the presence of three anterior teeth on the fixed finger instead of two. Sedna is characterized by the presence of spatulate ctenidia on male spiracular sternites, absent in Chileotrecha and Procleobis .
