male holotype: Total length 12.0 mm.

                            LENGTH         WIDTH
Chelicerae         3.1 mm             1.8 mm.
Propeltidium    1.7                     2.6
Palpi                   12.0                   CL/CW=2.38
First Legs           8.5                     PW/PL=1.53
Fourth Legs       14.0                  A/CP=7.10         
                                                        CP=4.8 

       
       Coloration in alcohol somewhat faded but apparently pale yellow with dark eye tubercle, reddish duskiness on tarsus, metatarsus, tibia, and apical end of femur of palpus and a reddish duskiness on femur and tibia of leg 4.  All other structures pale or indistinctly dusky.
        Structure not entirely typical but approaching that of group as indicated in diagnosis above.  Measurements and ratios, figure 54 of chelicerae, and figure 55 of abdominal ctenidia further characterize the species.  No anterior or mesal teeth on movable cheliceral finger, but there is only one tiny denticule just distal of primary tooth.  Both rows of fondal teeth are graded in size I, III, II, IV and there is an indistinct cup-like hollow apically on both of the cheliceral fingers.  Palpal metatarsus 3 times the length of the tarsus.
