HOLOTYPE: Costa Rica: Tristan, 1 male (holotype).

FEMALE HOLOTYPE: Total length, 20.0 mm. Chelicerae, 1.2 mm. wide and 3.6 mm. long. Propeltidium, 2.6 mm. wide and 2.1 mm. long. Coloration in alcohol white to light yellow, with dusky brownish purple markings as follows: chelicerae with two thin dorsal stripes and one lateral stripe that coalesce into a large rectangular spot at the base of the fingers on the ectal margin; propeltidium dusky on the anterior and lateral margins, leaving a longitudinal, light, diamond-shaped area, two medial, light, triangular areas on the posterior margin and two small, oval, light areas on either side of the eye tubercle; mesopeltidium, metapeltidium, and abdominal tergites with a broad, dark, median band which contains an elongate light spot on each segment near the lateral margin, forming a pair of thin, lateral, intermittent, light stripes; legs and palpi dusky above on all segments except the coxae, trochanters, and basal femora, the dusky markings are darker in the middle of each segment, causing the legs and palpi to appear annulate; eye tubercle dark; malleoli light yellow except for a narrow dark stripe on the margins. Dentition typical of the Ammotrechinae as shown in figure 277. The peak of the dorsal carina occurs over the space between the principal tooth and first fondal tooth of the ectal row. Palpi clothed ventrally with long and short hairs, a few scattered cylinder bristles, and two pairs of, and one or two unpaired, very small, cylindrical spines situated near the apical ends of the metatarsi. There is no series of spines on the tibiae. Chelicerae three times as long as wide. Propeltidium wider than long by a ratio of 1 to 1.2. Eyes about one diameter apart. Genital plate typical of family; it is wider than long by a ratio of 1 to 1.4.
