Original description
Muma, 1986: 12-13, figs 30-34:

male holotype: Total length, 22.0 mm.

                            LENGTH         WIDTH
Chelicerae         5.2 mm             2.3 mm.
Propeltidium    2.3                     4.2
Palpi                   19.0                   CL/CW=2.26               
1st legs               10.0                   PW/PL=1.83
4th legs              17.0                   A/CP=7.60

        Coloration in alcohol pale to rusty yellow with indistinct purplish brown markings as follows: eye tubercle dark; propeltidium lightly dusky except for a large, median, ovate, pale area; mesopeltidium, metapeltidium and abdominal tergites reticulate dusky; abdominal pleura pale; chelicerae, palpi and legs pale except for extreme distal end of palpal metatarsus and tarsus which are lightly dusky; venter and malleoli pale.
        Structure similar to that of E. andreasana but specifically different as indicated in measurements and rations given above, figures 30 and 31 of the chelicera, and figure 32 of the abdominal ctenidia.  There is no mesal tooth on the movable finger of the chelicerae, the setal articulation area of the fixed cheliceral finger occupies two-thirds of the length of the finger.  There is no palpal scopula, the ventral spine-like setae of the palpus are too slender to count, and the palpal metatarsus is 3.3 times the length of the tarsus.

female allotype: Total length, 21.0 mm.

                            LENGTH         WIDTH
Chelicerae         5.5 mm             2.1 mm.
Propeltidium    2.2                     3.9
Palpi                   15.0                   CL/CW=2.62               
1st legs               11.5                   PW/PL=1.77
4th legs              19.5                   A/CP=6.00

        Coloration in alcohol similar to that of male but much more distinct.
        Structure similar to that of E. andreasana with specific differences as indicated in the measurements and rations given above, figure 33 of the chelicerae, and figure 34 of the opercula.  There is no mesal tooth on the movable cheliceral finger and there are 2 trace ctenidia on the first post-stigmatic abdominal sternite.
