Morphology: Carapace (Fig. 11): Longer than wide. Median eyes on anterior 35%. Ocular tubercle low, without superciliary crests. Median eyes 0.2 mm in diameter. Three pairs of lateral eyes, posterior-most smallest. Anterior median furrow narrow and distinct. Posterior median furrow shallow, less distinct.

Tergites: Coarsely granular, particularly on lateral and posterior margins. Tergite VII with four well-developed carinae. Sternum (Fig. 17): Subpentagonal, slightly broader than long; median longitudinal furrow deep; with 8 setae (nearly symmetrical in arrangement). Genital opercula (Fig. 17): Well-developed, with ten visible setae or setal sockets each. Pectines (Fig. 17): With 6/7 middle lamellae, of which the proximal appear to be partially fused; 10 teeth on each side, the most distal of which is weakly expanded laterally. Sternites: Anterior (stigmata-bearing) sternites

Telson (Fig. 10): Vesicle robust, slightly wider than fifth metasomal segment; rugose ventrally, sparsely setose. Aculeus without basal patches of microdenticles. Chelicera: Fixed finger shorter than chela width, movable finger shorter than chela length. Chela with 3 setae dorsally. Fixed finger with basal bicusp nearly symmetrical (distal cusp slightly larger); ventral margin lacking accessory denticles. Movable finger with two dorsal subdistal teeth; with a distinct serrula ventrally, and with ventral carina smooth and strongly delineated. Pedipalp femur: Dorsointernal, externomedial, dorsoexternal, ventrointernal, and internomedial carinae strong, coarsely granular; ventroexternal carina obsolete. Orthobothriotaxia

Walking legs: Typical of the genus. Prolateral and retrolateral pedal spurs present on all legs; tibial spurs absent. Ventral surface of tarsus with single median row of spinules, this terminating distally in two pairs of spinules (one prolateral pair and one retrolateral pair). Unguicular spine well-developed and pointed.

Specimens were collected on 6 May 2013 and 23 September 2013. Two were found during the day on 6 May beneath rocks in moist leaf litter along a steep rocky drainage. The remaining specimens were collected by UV detection at night on 23 September. All were found on or near the bottom of a rocky embankment next to the highway. The area is characterized by oak-dominated woodlands on the drier south-facing slopes and mixed-conifer forest on the cooler north-facing slopes. Most
