Type Material

Holotype: “Male holotype from NE El Paso Mts., Kerr Co., California in the spring of 1963 by D. Gibo in AMNH” (Muma, 1989, p. 29).

Measurements: Male holotype: Total, 14.0 mm length. Chelicera, 4.7 mm length; 1.8 mm width. Propeltidium, 2.1 mm length; 3.1 mm width. Palpus, 17.0 mm length; CL/CW=2.61. Leg I, 13.0 mm length; PW/PL=1.48. Leg IV, 20.5 mm length; A/CP=7.43. CP=6.8.

Chelicerae Description: “No mesal tooth on movable cheliceral finger; mesoventral groove of fixed cheliceral finger does not extend basally into fondal notch; fondal tooth sizes are I, III, II, IV for ectal row and I, II, III, IV for mesal row” (Muma, 1989, p. 29).

Palpal Description: “Palpi seem to be dusky apically on femora and all of tibiae, metatarsi, and tarsi. . . . There are 14 or 15 long, slender, spine-like setae ventrally on femora and tibia of palpi; those on the metatarsi are indistinguishable” (Muma, 1989, p. 29).

Diagnosis: “Small species seeming to be most closely related to E. bilobatus from which it differs by having a palpal scopula of about 50 tiny scopae. Distinguished from most species of group by longer mesoventral groove of fixed cheliceral finger. Four very long, slender ctenidia, long slender, spine-like, palpal setae, and reduced dentition of movable cheliceral ginger separate it from sympatric E. morrisi” (Muma, 1989, p. 28).
