 Eyes. Seen from in front, anterior row recurved so that a line tangent to dorsal borders of ALE cuts off about one eighteenth of the diameter of AME. Posterior row wider than anterior row in ratio of about 13 : 11, wider than middle row in ratio of about 13 : 10. Quadrangle of laterals wider than long in ratio of about 13 : 9. Total eye space occupies about five sevenths of the length of the carapace. Ratio of eyes AME : ALE : PME : PLE = 18 : 9.5 : 2.3 : 9. AME barely separated from one another, from ALE by one eighteenth of their diameter. Middle row closer to ALE than to PLE in ratio of 15 : 11. Height of clypeus equal to one sixth of the diameter of AME. Clypeus decorated with a rich coat of long white lanceolate hair which shows some iridescence, two long white bristles beneath each AME, and three long upturned yellowish bristles in lower angle between AME.

Chelicerae. Fairly robust, vertical, parallel; well rounded in front where there are many short white loose scales; no basal boss observed; basal segment .57 mm. long. Fang fairly robust, evenly curved. Fang groove distinct; with two promarginal teeth, inner small, outer of moderate size; retromargin with a single typical fissidentate tooth.

Maxillae, Lip, and Sternum. Essentially as in male.

Legs. Tibial index of first leg 18, of fourth leg 12.

Spines. First leg: patella 0; elsewhere as in male except tibial and metatarsal spines more robust. Second leg: femur only dorsal 0-0-1-1; patella 0; tibia only ventral 1r-1r-1r; metatarsus as in first. Third leg: metatarsus only prolateral 0-2, retrolateral 0-1; elsewhere as in male. Fourth leg: femur dorsal 0-1-0-1; patella 0; tibia only ventral 1p-0-2; metatarsus as in male. No palpal spines observed.

Abdomen. Much more robust than in male; longer than wide in ratio of about 3 : 2, widest in middle; with no indication of a dorsal shield; other features essentially as in male.

Epigynum. Simple; with a shallow acute posterior marginal notch; main part of plate somewhat swollen through middle; near anterior border are two depressions nearly two diameters of one of them apart (Fig. 372).
