Legs ( Fig. 10 A, B). Coxae I–II with one anterior dorso basal apophysis and one posterior; III with anterior dorso basal apophysis; with one small internal spiniform apophysis and one external apical bifid apophysis, directed ventrally. Trochanters I–III with small scattered tubercles; IV with one dorsal subapical apophysis and one external basal apophysis.

Penis ( Fig. 18 A–C). Ventral plate convex, apex straight; three pairs of distal setae, one pair of median setae, three or four pairs of basal setae, arranged in “U” and one pair of basal ventral setae. Stylus unarmed, apex straight and swollen. Ventral process almost parallel to the stylus, truncus short, apex spoon-shaped, with long serrate margins directed ventrally.

Coloration ( Fig. 15 C). Dorsal scutum and apophyses of area III dark-brown. Ocularium yellow-dark. Tubercles of dorsal scutum (rows up to the grooves) greenish.

Female redescription ( Figs. 12 A, 14A). Measurements (n=10). Dorsal scutum; maximum width: 3.3–4.6; total length: 3.8–4.7; length of prosoma: 1.4–2.1. Femur IV length IV: 10.3–14.9. Tarsal formula: 7–8; 15–17; 8– 10; 7–8. Ocularium with one pair of high apophyses and one pair of tubercles behind them. Prosoma with tubercles behind ocularium arranged in “U”. Area I and II unarmed, III with a pair of apophyses (larger than ocularium); posterior margin of dorsal scutum and free tergites unarmed. Coxa IV with small external apical spiniform apophysis; internal apophysis absent. Trochanter IV unarmed; femur IV shorter than male.

Geographical distribution. Costal Atlantic Rain Forest of Paraná and southeastern of São Paulo States ( Fig. 3 A).

Remarks. The holotype of Promitobates hauseri is considered as lost, but the good drawing and informative illustration, as well additional material from type locality (Eldorado Paulista, Gruta da Tapagem - MNRJ 18794) lead us to recognize them as cospecific.
