Why not parvulum?
Hi, Lynette-

Is there a reason that specimens such as these are not placed directly under Synema parvulum? According to Gertch's (1939) keys to the species: "Abdomen with a large dark caudal maculation, otherwise pale. Eyes of anterior row nearly straight. Carapace light brown ....... . S. parvulum (Hentz)."

Or is there more recent information that suggests otherwise?

Not that I know of
except that we just didn't know what might be similar in the area. Do you know of anything this may be confused with? I don't think I've ever found a good list of spiders for NC.

Similar specimens would inclu
Similar specimens would include the other Synema species, I think, but Gertsch keys these out (uncommon though it may be) according to descriptive characteristics, including those already mentioned. Synema globosum has its own distinctive appearance; viridans has a green carapace and legs, according to Gertsch; and then there is S. neomexicana (carapace uniformly dark brown, dorsum of abdomen grey to white), but the type specimen comes from Las Vegas.

He also mentions a S. bicolor (glistening black carapace and grey dorsum) and a S. obscurum (carapace brown with pale dorsal stripe), but what has happened to these I do not know...

The description of S. synema seems pretty unequivocal. I just thought that perhaps there is something that I am missing.
