Type material. Holotype ♂: BRAZIL: Rio Grande do Sul: Santa Maria, Barragem Saturnino de Brito [S29.52418°, W53.80271°], A.A. Lise leg., 14.VII.1982 (MCN 10584).
Etymology. The name is a patronym in honor of Izaura da Conceiç ã o Magalh ã es Muniz Maschiro (nicknamed “Iza”), assistant of the MPEG Arachnology Collection.
Diagnosis. Males of Falconina iza sp. nov. are similar to those of F. catirina sp. nov. by the well-developed RTA median lobe and by the small, triangular dorsal lobe. They differ by the shorter sub-squared median lobe, with truncated apices (Figs 17B, 18B), and by the large, prolaterally inserted lamelliform embolus, with a wide-spanned embolar process (Figs 17A, 18A).

Chelicerae with three promarginal teeth, the second two times longer, and five retromarginal teeth, the most proximal to fang three times smaller than others. Sternum 1.440 long, 1.399 wide.

Male palp. Tibia almost half of cymbium length. Three lobes. Ventral lobe with well-developed dorsal process (dVL), a long and thin apical spur, longer than both median and dorsal lobes.
