Original description
Muma, 1989: 22-23, figs 28-31:

males:  (3 specimens) Total length, 20.0 to 26.5 mm.

                            LENGTH             WIDTH
Chelicerae         0.60-0.70 mm     0.30-0.30 mm.
Propeltidium    0.30-0.40             0.40-0.50
Palpi                   22.0-25.07           CL/CW=2.0-2.3              
1st legs               18.0-19.0             PW/PL=0.75-0.80
4th legs              24.0-28.0             A/CP=7.11-6.45
                                                           CP=0.90-1.10


        Holotype larger measurements.
       Color in alcohol pale to dusty, and rusty yellow sparsely marked with purplish brown as follows: eye tubercle dark; propeltidium pale to dusty yellow throughout; mesopeltidum, metapeltidium, and abdominal tergites, pleurites, and sternites seemingly an unmarked combination of dusty and rusty yellow; chelicerae, palpi, and legs a pale to distinct rusty with only palpal tarsi and distal ends of metatarsi lightly dusky.
       Structure similar to ivei and medialis with specific differences as shown in measurements and ratios, figure 28 of chelicerae, and figure 29 of abdominal ctenidia.  No distinct mesal tooth on movable cheliceral finger, fondal teeth graded in size I, II, III, IV for both rows, and two denticules in fondal notch; ECCS shown at 140x.  An elongate scopula of 30-40 papillae in palpal metatarsus which is 3 times length of tarsus.

FEMALE ALLOTYPE: Total length, 24.0 mm.

                            LENGTH         WIDTH
Chelicerae         0.70 mm           0.20 mm.
Propeltidium    0.40                   0.30
Palpi                   19.0                   CL/CW=3.5             
1st legs               14.0                   PW/PL=0.75
4th legs              25.5
                   A/CP=5.31
                                                        CP=1.10
        Coloration and markings of allotype very similar to holotype.
        Structure similar to other species of group as shown by measurements and ratios, figure 30 of chelicerae, and figure 31 of opercula.  Opercula structure is most similar to iviei and malkini.

PUBLISHED RECORDS: United States. Arizona: Maricopa County - 3 mi S of Wickenburg, 15 August 1976 (T. Kingsley), 1 male (paratype).  Retained in Muma's personal collection.
