Type localities. BRAZIL. Of Cadeadoius atroluteus : Santa Catarina, Seara: Nova Teutônia. Of Piraquara schubarti : São Paulo, Itanhaém: Serra Piraquara . Of Ampheres striatus : Bahia. Of Progonyleptoidellus androgynus : São Paulo, Santo André: Alto da Serra. The type localities in the Brazilian states of Bahia and Santa Catarina are dubious and probably mislabeled considering that there are no additional records of the whole genus from these states.

Geographical distribution ( Fig. 9 ). BRAZIL: Southeastern portion of the state of São Paulo.

Diagnosis. Males (see Fig. 7A ): Progonyleptoidellus striatus can be distinguished from the other species of the genus by the following combination of characters: pedipalp coxa small; all scutal areas unarmed; scutal area III with two paramedian short tubercles; free tergites I–III unarmed. Proapical apophysis of coxa IV strong and often with curved and bifurcated apex, ventral branch rounded and small. Trochanter IV retrolaterally with short apical spine; prolaterally with large, triangular sub basal spine. Femur IV: DBA anvil-shaped, fused basally with the sub DBA (triangular shaped); with seven rows of armature — dorsally with two rows, one more prolateral (with a few small spines), and one retrolateral of spines along the entire article, decreasing in size apically; prodorsally with a row of short spines, all article long (more concentrated in the apical half); retrodorsally with strong spines along the article (the largest in the medial part; these are the strongest spines on femur IV); an extra row in the apical part, between retrodorsal and second dorsal rows; and ventrally with two rows of spines throughout article, increasing in size apically; carapace black with lateralmost parts yellowish. DS areas with dark black bands; dry-mark on ocularium (between the eyes), carapace (behind the ocularium), weakly on transversal DS sulci. Penis with macroseta B of the same size as macrosetae A.

Female (see Fig. 7B ): This species can be distinguished from the others in the genus by the following combination of characters: Scutal area III with two small acuminate tubercles; proapical apophysis of coxa IV long (smaller than males), straight and acuminate (apex more rounded than males); femur IV without DBA, armed with seven rows of spines (in a different pattern than males); coloration like in males.
