Benedetti, Alípio R. & Pinto-Da-Rocha, Ricardo, 2019, Description of two new species of Progonyleptoidellus (Opiliones: Gonyleptidae), with a cladistic analysis of the genus, an overview of relationships in the K 92 group, and taxonomic notes on Deltaspidium, Zootaxa 4691 (5), pp. 461-490 : 474

Key to the males of Progonyleptoidellus

1. Femur IV with dorso-basal apophysis (DBA, see Kury & Pinto-da-Rocha, 1997: figs. 1, 2)........................... 2

- Femur IV without DBA ( Figs. 2B , 4B ).................................................................... 3

2. DBA (=anvil-shaped), merged into the base with the sub DBA; with two small tubercles on scutal area III............................................................................................ Progonyleptoidellus striatus

- DBA acuminate, simple, retrolaterally directed; with a pair of spines on scutal area III (see Kury & Pinto-da-Rocha, 1997: fig. 1)......................................................................... Progonyleptoidellus fuscopictus

3. Pedipalp coxa long (reaching the apical margin of trochanter IV); basitarsus I not swollen (like the distitarsus); femur III unarmed; tibia IV unarmed ( Fig. 4 ).......................................... Progonyleptoidellus picinguaba sp. nov.

- Pedipalp coxa short (not reaching apical margin of trochanter IV); basitarsus I swollen; femur III with ventroapical acuminate tubercles; tibia IV ventrally armed........................................... Progonyleptoidellus bocaina sp. nov.
