35–39 (male holotype from Key West , Florida (1 3) (24.55917°, -81.78389°), Dec. 31, 1950, A.M. Nadler, deposited in AMNH, PBI_OON 42746; female paratype from the same locality, Dec. 29, 1950, A.M. Nadler, deposited in AMNH, PBI _OON 42572; examined) – Wunderlich, 1988: 57, fig. 47 .

DIAGNOSIS: Males can easily be distinguished by the shape of the copulatory bulb, more oval in lateral view, embolus and bulb clearly delimited; the sperm duct has many loops, which is also a clear difference from the other species from the United States. Females resemble those of O. auburndalensis by the shape of the abdomen, more oval in lateral view, but lack external pockets on the epigastric area.

MALE (PBI_OON 42746): CEPHALOTHO- RAX: Laterals of carapace with dark pigment. Sternum wider than long, laterals with dark spots or patches of dark pigment, with dark stripe on anterior median half. Chelicerae anterior face with basal conical projections. Labium triangular. ABDOMEN: Dorsum with diffuse netlike pattern. Spinnerets with only a few long, needlelike setae. LEGS: White; patella plus tibia I shorter than carapace. GENITALIA: Palp proximal segments yellow; bulb yellow; embolus dark; broad ovoid; sperm duct slightly coiled with few loops.

FEMALE (PBI_OON 42572): Total length 1.5.

CEPHALOTHORAX: Sternum longer than wide.

GENITALIA: Epigastric region without external or internal pockets; anterior receptaculum with anterior apodemes placed on tip; 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.
