TYPE: Female holotype from Auburndale, Florida (28.101111°, -81.793611°), Mar. 04, 1936, collector not provided, deposited in AMNH, PBI_OON 1449.

ETYMOLOGY: The species is named after the type locality, Auburndale.

DIAGNOSIS: Females of this species can be distinguished by the general shape of the body, which is longer, with tubular, more elongated abdomen, instead of rounded or globular as in other species. The epigastric region shows external pockets that are slightly extended posteriorly. Curiously the general shape of the female genitalia resembles that of O. fernandina from the Galapagos Islands in having an anterior receptaculum with wide base and external pockets, but in that species the pockets are closer to each other over the epigastric furrow.

MALE: Unknown.

FEMALE (PBI_OON 1449). Total length 1.38. CEPHALOTHORAX: Labium rectangular. ABDOMEN: Cylindrical, posterior end of abdomen with slightly brown pattern similar to other North American species. LEGS: Missing. GENI- TALIA: Epigastric area with external pockets extended slightly posteriorly, internal pockets absent; anterior receptaculum with rounded anterior tip, wide base, anterior apodemes absent; posterior receptaculum present, posterior apodeme formed by entire plate.

DISTRIBUTION: Known only from the type locality in the United States (Florida, map 1).

OTHER MATERIAL EXAMINED: None.
