Measurements: "DIAGNOSIS: The distinctive markings and the possession of two rows of 10 or more unpaired cylindrical spines on the metatarsus and tibia of the palpus readily identify this species.
FEMALE HOLOTYPE: Total length, 15.0 mm. Chelicerae 1.0 mm. wide and 3.1 mm. long. Propeltidium 2.4 mm. wide and 1.9 mm. long. Color and markings in alcohol somewhat faded but apparently as follows: chelicerae light yellow; propeltidium pale, dusky, purplish brown except for a narrow, light yellow, median stripe, a small oval light area on each side of eye tubercle, a large, longitudinal, light, diamond-shaped area, two irregular median light areas near the posterior margin, and a light yellow posterior marginal band; mesopeltidium, metapeltidium, and abdominal tergites light except for narrow lateral and posterior dusky margins; all legs pale yellow except for first pair which are pale dusky purple on tarsi, metatarsi, tibiae, and femora; palpi dusky purple on tarsi, metatarsi, tibiae, and apical ends of femora; eye tubercle dark, malleoli white.
Dentition of chelicerae typical of the Ammotrechinae (fig. 50). Peak of dorsal carina occurring over first fondal tooth of ectal row. Palpi clothed with long and short hairs, scattered cylinder bristles on tarsi, metatarsi, and tibiae, and two rows of 10 or more short, unpaired, cylindrical spines on ventral surface of metatarsi and tibiae (fig. 51). Chelicerae three times as long as wide. Propeltidium wider than long by a ratio of 1 to 1.2. Eyes slightly less than one diameter apart. Genital plate typical of family, wider than long by a ratio of 1 to 1.5. (Muma, 1962, P. 41)
