BULLETIN: MUSEUM OF COMPARATIVE ZOÖLOGY

Palp. Femur only slightly bent ventrally; both patella and tibia short with latter about two thirds as long as former; tibial retrolateral apophysis a short stout spur turned inward at tip; embolus a slightly curved slender spine at tip of bulb (Figs. 365-366).

Abdomen. Almost a perfect oval in outline; longer than wide in ratio of 19 : 15; with a moderately well developed dorsal shield covering nearly entire dorsum; anal tubercle an inconspicuous yellowish white cone; six spinnerets small and closely crowded, anterior pair stoutest; position of colulus uncertainly indicated; tracheal spiracle near base of spinnerets with lip but no tubercle.

Color in alcohol. Carapace: almost uniformly reddish brown; eyes on black spots; white hairs on clypeus continued beneath ALE and PLE to posterolateral corners and part way down posterior declivity as a somewhat indefinite stripe on each side. Sternum and mouth parts different shades of reddish brown and brown. Legs: first pair entirely reddish brown except the yellowish tarsi; second and third pairs yellowish white with brownish ventral spots near distal ends of femora and brownish spots at intersections of patellae, tibiae, metatarsi, and tarsi; fourth pair yellowish white with brownish ventral spots near distal ends of femora and brownish spots at intersection of patellae, tibiae, metatarsi, and tarsi; fourth pair yellowish white with brownish prolateral spots on coxae, distal two thirds of femora reddish brown and brownish spots at intersections of patellae, tibiae, metatarsi, and tarsi. Abdomen: dorsal shield reddish brown overlying a series of brownish and yellowish chevrons in posterior two thirds; dorsolaterally on each side is a discontinuous white stripe from base to about the middle, then a white spot half-way to spinnerets; lateral sides brownish with narrow alternate brownish and yellowish stripes; venter with a broad brownish stripe from genital groove to base of spinnerets.

Female allotype. Total length 3.07 mm. Carapace 1.28 mm. long, 1.09 mm. wide at level of PLE, .70 mm. tall and, therefore, 0.64 as tall as wide; other features essentially as in male.

Eyes. Seen from in front, anterior row recurved so that a line tangent to dorsal borders of ALE cuts off about one tenth of the diameter of AME. Posterior row wider than anterior row in ratio of about 25 : 23, wider than middle row in ratio of about 25 : 21. Quadrangle of laterals wider than long in ratio of 10 : 7. Total eye space occupies two thirds of the length of the carapace. Ratio of eyes AME : ALE : PME : PLE = 15 : 8 : 2 : 8. AME barely separated from one another and from ALE. Middle eyes closer to ALE than to PLE in ratio of about 11 : 10. Height of clypeus equal to about two fifteenths of the diameter of AME. Clypeus decorated as in male.
