apart, a little less than their diameter (six sevenths) from the laterals. 
Anterior row of eyes much shorter than the posterior (41:31); straight 
or scarcely recurved; medians smaller than the laterals (ratio of 
diameters 5:7), slightly more than their radius apart (three fifths 
diameter) and almost contiguous with the laterals. Clypeus narrower

breadth; three fourths as wide in front as behind. 
Sternum longer than wide nearly in ratio 15:11.

mesally at distal end. 
Lower margin of furrow of chelicera with four or five teeth of which 
the two more distal are longer than the others. 4 
Tibia I with three pairs of ventral spines of which the distal are 
short and those of the other two pairs long; also bearing on the 
anterior side three spines and one dorsally. Metatarsus I below with 
a basal pair of long appressed spines; on anterior side with two spines 
of which the basal is smaller than the median, and three pairs of 
dorsal or subdorsal spines. Femur I with three spines along mid- 
dorsal line. Anterior tarsi scopulate; metatarsi sparsely scopulate 
distad; posterior tarsi scarcely truly scopulate or with but few scopu- 
lar hairs. 
Distal article of superior spinnerets abruptly narrower than the 
proximal, cylindroconical, small. 
Rima ventralis nearly equidistant between bases of spinnerets and 
the genital furrow.
