Orchestina saltitans Banks, 1894: 300 (male holotype from the United States: New York, Sea Cliff (40.848989°, -73.644850°), July, 1894, Nathan Banks, deposited in MCZ 22976, PBI_OON 42750; examined). – Emerton, 1909: 214, pl. 1, figs. 4 (Dm). – Dalmas, 1916: 239, figs. 24–25, 35–36 (m). – Petrunkevitch, 1920: 158, pl. 9, figs. 1–9 (m). – Kaston, 1938: 12 (Df). – Comstock, 1940: 311, fig. 290 (m).

Orchestina saltabunda: Petrunkevitch, 1910: 207 , pl. 21, figs. 2–3 (m, misidentified).

NOTE: The collection number of the type specimen is missing, but it is provided in the online catalog of the MCZ collection. We have added a label with this number to the vial.

DIAGNOSIS: Males are similar to those of the other United States species but are easily distinguished by the absence of a conical projection on the promargin of chelicerae (present in O. obscura and O. utahana ) and by the long embolus, shorter in other species (figs. 16G–I, 20L, M). Females lack the external pockets on the epigastric region characteristic of O. moaba , O. utahana , O. kamehameha , O. quasimodo , and O. auburndalensis and can be distinguished from those of O. nadleri by the shape of the anterior receptaculum thinner and longer in O. nadleri , and by the subapical position of the anterior apodemes, placed on the tip of the anterior receptaculum in O. nadleri (figs. 18E, 19E, 22A).

MALE (PBI_OON 42750): Total length 0.92.

CEPHALOTHORAX: Carapace orange-brown, with net-shaped pattern (fig. 12A, B, D). Sternum orange-brown, with net-shaped pattern (fig. 12C). Chelicerae, endites, labium orange-brown. Labium rectangular. Endites without serrula.

ABDOMEN: Dorsum with gray netlike pattern (fig. 12A, B). LEGS: Yellow, patella plus tibia I longer than carapace. GENITALIA (figs. 16G–I, 20L, M): Palp segments yellow with diffuse pattern of brown spots or patches; bulb yellow, spherical; embolus long, dark, sperm duct not very coiled, with only one loop.

FEMALE (PBI_OON 42750): Total length 1.42.

CEPHALOTHORAX: Sternum yellow (fig. 12F). Endites with serrula in single row. LEGS: Patella plus tibia I near as long as carapace. GENITALIA (figs.18E, 19E, 22A): Epigastric region without external pockets, internal pockets absent; anterior receptaculum short, twisted ventrally, with short anterior apodemes; posterior receptaculum present, massive; posterior apodeme formed by entire plate.

DISTRIBUTION: Known only from the eastern region of the United States (map 1).
