Appearance
"Neoscona oaxacensis" is a relatively large spider, females being about 9–18 mm long overall, with a carapace of about 4–8 mm long by 3–6 mm wide. Males are smaller, being about 6–13 mm long overall, with a carapace of about 3–6 mm long by 3–5 mm wide. Specimens from the Galápagos are among the largest found. The black-and-white pattern on the upper surface of the abdomen is considered to be distinctive. South American specimens have a more slender abdomen than North American ones, with a more distinct light central band, which has a wavy border. Females have an epigyne appearing 2.5 times as long as wide when viewed from the rear. Males have a palp with an S-shaped conductor.References:
