Taxonomy
Order: ARANEAEInfraorder: AraneomorphaeFamily: Araneidae                                                                                 
Comments: This species has borne many scientific names since its original description as Epiera crucifera by Lucas in 1898, including E. lentiginosa, E. hentzii, E. domiciliorum, Aranea c., Neoscona benjamina, N. arkansa, N. nebraskensis, N. sacra, N. hentzii, and N. hentzi.

Interestingly, Simon erected the genus Neoscona in 1864 when he was only 16 years old, and his mastery of Greek seems to have been rather "shaky" (Look Who's Talking Dept. --dbz): It is relatively clear that he meant "spinning among the reeds," but Neoscona translates literally as "spinning a reed." In 1869, Thorell charitably tried to correct this with the spelling "Neoschoena," but this was rejected by Bonnet (1958) who decided that the original spelling should be retained "even if incorrectly written"—although he agreed with Thorell.

The specific epithet crucifera references the cross-like markings that sometimes are visible on the opisthosomata of these spiders.

Species Comment: Although this species does not have a common name recognized by the American Arachnological Society, among its colloquial names are: cross orbweaver, Hentz (or Hentz's) orbweaver, arboreal orbweaver, or rusty-red Neoscona, though the last of those can be misleading, as they are often other colors, including brown, orange, and gray, and can have no markings to speak of or even resemble the usually more distinctly marked N. domiciliorum.
Identification
Online Description/Photos: The prosoma is yellow to brown, and it often has abundant hairs. The males often have a dark prosoma with a median stripe of light-colored hairs. The opisthosoma is highly variable in color and markings. Some are overall tan to yellow and can look very much like Eriophora ravilla. (Note that the ventral markings are quite different.) Others are boldly patterned and easily confused with Neoscona domiciliorum (in which case, examination of the genitalia may be the only way to confirm a species-level identification). Most have a tan to brown abdomen, with a lighter cross in the middle. The ventral opisthosoma is black, with horizontal yellow dashes at the epigastric furrow, and paired longitudinal yellow dashes toward the spinnerets.

Comments: While the marking of N. crucifera can be confused with those of N. domiciliorum, the adult females can readily be distinguished by the former's much longer and distinctly lobed scape.
