I'm in the middle of trying to learn exactly how separable the species in this genus are without genitalia exams (spiders are identified via structures of the pedipalp (in males) or the epigyne (in females), which typically means having the specimen in hand and seeing it under a microscope). Some spiders simply are not identifiable without that. Scytodes seems to be one of those (not sure why the two species that are already in BugGuide were separated)... but I am recently trying to learn more with the help from Cristina Rheims (Instituto Butantan, Brasil) and her papers on this genus. Some species might have field identifiable cues that help to place them to species, I just need to study more. The issue with Scytodes is that most are synanthropic (live in human habitations) so the potential for them to be imported from all over the world is a concern when IDing them; you never know from regular habitus shots if it's even a native species. Besides that, a single species can vary in color and pattern, as well. It's just a pretty difficult genus, at least for me and for BugGuide at the time being... but you never know, we might get to the bottom of it. So don't expect a species ID too soon, but don't lose hope either. :-) If you happened to keep the spider, you can submerge it in alcohol and myself or others here on BugGuide (e.g. Kevin Pfeiffer) can ID it under a 'scope if you mail it to us. That'd be the only way to be 100% sure of the ID. Even once we learn more, an ID based solely on these shots (as wonderful as they are) would just be a guess without the genitalia exam.
