Typhlodromalus araucariae Gonçalves & Ferla  n. sp.

( Figs 7–11View FIGURES 7 – 11)

Diagnosis. Typhlodromalus araucariae Gonçalves & Ferla  n. sp. differs from the other Typhlodromalus  species by the following combination of characters: details of spermatheca: atrium strongly sclerotised, calyx elongate and posteriorly enlarged; setae of the dorsal shield stout (except j 4, j 5, j 6, J 2, J 5 and z 5), setae Z 4 not serrate and not as long as distance between its base and that of setae S 4, and there is one macroseta on tarsus IV with a very small terminal knob. This is the only Typhlodromalus  species that features only one macroseta on leg IV.

Adult Female. Five females examined. Idiosomal setal pattern ( Chant & Yoshida-Shaul, 1992): 10 A: 10 B/ JV- 3: ZV.
