Hetschkia gracilis Keyserling, 1886, Die Spinnen Amerikas, Theridiidae, 
2(2): 247, pi. 20, fig. 299, $. Male holotype from Blumenau, [Santa 
Catarina], Brazil in the Museum National d’Histoire Naturelle, Paris, 
examined. 
Description. Female. Carapace, sternum yellow. Legs yellow with 
tarsi brown and anterior side of each patella with a black spot. Abdo- 
men whitish, unpigmented. Carapace sclerotized, slightly granulate, 
almost smooth. Sternum fused to carapace but with seam present 
above coxae. Carapace and sternum fused around pedicel (Fig. 7). 
Eyes subequal in size. Anterior median eyes one and one-half diame- 
ters apart, their radius from laterals. Posterior median eyes two 
diameters apart, one and one-half diameters from laterals. Abdomen 
spherical. Total length of female from Sao Paulo 2.2 mm. Carapace 
1.20 mm long, 0.61 mm wide. First femur, 1.32 mm; patella and 
tibia, 1.2 1 mm; metatarsus, 1.19 mm; tarsus, 0.45 mm. Second patella 
and tibia, 0.90 mm; third, 0.62 mm; fourth, 0.90 mm. 
Figures 12 and 13 were prepared from the holotype. 
Records. Brazil. Sao Paulo: Botanical Gardens, Sao Paulo, 13-

Wirada Keyserling 
Wirada Keyserling, 1886, Die Spinnen Amerikas, Theridiidae, 2(2): 25. 
Type species by monotypy: IV. punctata Keyserling. 
Carapace with eye region projecting and clypeus sloping back 
toward chelicerae. Carapace and sternum tuberculate (Figs. 18, 25, 
26). Legs short; leg four about equal to leg one. Tarsi longer than 
metatarsi. Abdomen with a dorsal sclerotized shield, a large shield 
surrounds pedicel and a sclerotized ring around spinnerets (Figs. 24, 
25) . Colulus replaced by two setae. 
The tuberculate carapace resembles that of Crustulina; Wirada, 
however, lacks the distal process on the palpal cymbium and lacks 
a large colulus. The relatively simple palpus and long tarsi make 
Wirada resemble spiders placed in the family Symphytognathidae. 
Wirada species, like members of the latter family, have tarsi longer
