Individuals belonging to Gnaphosidae and Trochanteriidae families are difficult to tell apart with similar qualities and habitats - as far as I'm aware - so unless there's a specific reason for narrowing the ID to Hemicloea sp, I think it's better to have sightings of individuals belonging to these families in one place to sort further upon determining whether they can be distinguished with a decent degree of confidence. I haven't been able to look through properly yet, but Platnick N.I. (2002) has a revision publically available through ResearchGate on Gnaphosoids if you're interested. Thanks!
