Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Close relative of apacheanus, distinguished by following features: median eye tubercle placed well in front of middle of carapace but closer to center, 36 in chicano, 32 in apacheanus; carapace with distinct dark mottling; chela heavier, with shorter fingers, chela length over fixed finger length 2.62 in chicano, 2.35 in apacheanus.
...
COLORATION: Base color orange-tan with darker mottling on carapace and terga. Eye tubercles black. Keels on cauda and pedipalpi and aculeus dark brown. Walking legs yellow with dusky markings on all segments except tarsi.
STRUCTURE: Similar to that of apacheanus except as noted. Descriptive data and measurements as given in table 3.
Carapace: Surface covered with small granules, most noticeable on pigmented areas; frontal margin with six suberect setae. Frontal emargination deep, broadly rounded. Ocular tubercle well in advance of middle of carapace. Median eyes small, 0.17 mm., separated by their diameter. Lateral eyes three; posterior eye small, set above principal pair.
Preabdomen: Posterior half of first six tergites finely granulated; tergite VII with both pairs of keels well developed and serrate. First four sternites smooth; fifth sternite rough with fine granulation; keels essentially obsolete.
Cauda: Dorsal and dorsal lateral keels on segments I-IV serrate; inferior lateral keels of these segments serrate, and inferior median keels irregularly serrate. Lateral keels present on segments as follows: irregular serrate row on I, on posterior half of II, on posterior third of III, and essentially obsolete on IV except for scattered granules in intercarinal spaces. Keels on segment V as follows: dorsal keel crenulate; lateral keel irregular on anterior three-fourths; inferior lateral and single median keel serrate; intercarinal spaces essentially smooth, with some scattered granulation.
Telson: Sting sharply curved, delimited from vesicle by slight basal swelling; vesicle with about six pairs ofsetae on ventral surface.
Pectines: Like those of apacheanus; middle lamellae, five; pectinal teeth, nine.
Chelicerae: With normal dentition; lower margin of movable finger smooth except for line of serrulae.
Pedipalps: All keels on femur and tibia granulated. Femur two and one-half times as long as wide; tibia twice as long. Superior keel on chela smooth anteriorly, becoming rough posteriorly; outer accessory keel irregular, weak anteriorly; outer keel with rounded granules posteriorly; inner ventral keel essentially obsolete; inferior keel with rounded, irregular granules; inner secondary keel with large granules posteriorly; inner accessory keel smooth anteriorly but granulated posteriorly. Supernumerary teeth on fixed finger, six, on movable finger, seven. Trichobothria ib and it positioned directly above articular membrane.
Walking legs: Single ventral row of spinules on venter of tarsus small and delicate, flanked by three pairs of delicate setae."
