Chelicerae of male with one tooth on anterior margin. First femora

mm. Carapace 3.3 mm long, 2.4 mm wide. First femur 4.3 mm; 
patella and tibia 3.9 mm; metatarsus 2.9 mm; tarsus 1.5 mm. Second 
patella and tibia 3.2 mm; third 2.7 mm; fourth 3.9 mm. Total length 
of female 6.1 mm. Carapace 2.9 mm long, 2.1 mm wide. First femur
