Etymology. The epipthet refers to a kind of german beer made in low fermentation.
Diagnosis. Body densely granulated, area I totally covered by tubercles. It can be distinguished from P. weissbier sp. n. by coloration with os tubercles of dorsal scutum sulphurous yellow.
Male description. Measurements (n=5). Dorsal scutum; maximum width: 3.7–4.2 (4.1); total length: 3.9–4.6 (4.4); prosoma length: 1.4–1.8 (1.8). Leg IV; length of external apophysis of coxa: 0.8–1.2 (1.2); femur IV length: 21.7–38.4 (38.2). Tarsal formula: 6–8 (7); 14–16 (14); 8–9 (8); 8.
Dorsum (Figs. 6 D, 8F). Anterior margin of prosoma with frontal hump with one row of small tubercles. Prosoma with tubercles behind ocularium arranged in “U”, one longitudinal row of tubercles next to the ocularium and scattered tubercles. Ocularium with one pair of high spiniform apophyses small tubercles behind them. Area I with one row of tubercles near grooves (Fig. 6 D) or totally covered by tubercles (Fig. 8 F). Area II denselly tuberculated. Area III with two high spiniform apophyses and tubercles concentrated on median region. Area IV with tubercles on median region one row up to the posterior goove. Lateral areas with one row of tubercles which is placed from ocularium to area II and scattered tubercles. Posterior margin with one row of tubercles, enlarged in the corners and one pair of median spiniform apophyses. Free tergites with one row of tubercles. Anal operculum unarmed.
Chelicera. Segment I with two setiferous tubercles; II unarmed.
Pedipalp. Trochanter with one small ventral spine. Femur with one small ventral basal spine and one subapical, prolateral spine. Tibia mesal IiIi; ectal IiIi. Tarsus mesal IIi; ectal Iii/Ii.
Venter. Coxa I with median row of four setiferous tubercles and three apical tubercles; trochanter I with median tubercle. Coxa II with median row of nine small setiferous tubercles and three apical tubercles; trochanter II with two median tubercles. Coxa III with small setiferous tubercles, distributed roughly in rows, the anterior one and posterior one increasing in size distally; trochanter III with median tubercle. Coxa IV with scattered granules and four tubercles on posterior margin; genital area, free sternites I–III and anal operculum with small granules.
Legs (Fig. 10 F). Coxa I with one posterior dorso basal apophysis; coxa II with one anterior dorso basal apophysis and one posterior; coxa III with anterior dorso basal apophysis; coxa IV with few and high tubercles, with small internal spiniform apophysis and one external apical bifid apophysis. Trochanters I–III with small scattered tubercles. Trochanter IV with one dorsal subapical apophysis, one external basal apophysis and one small internal apical spiniform apophysis. Femur very long, straight and unarmed.
Penis (Fig. 19 D–F). Ventral plate distally with transversal median depression, lateral convex, apex straight and distal margin corner rounded and directed ventrally; three distal setae, the pair of setae median much smaller; three pairs of basal setae, ‘V”-shape and a pair of small basal ventral setae. Stylus unarmed, straight and of apex swollen. Ventral process almost parallel to the stylus, apex spoon-shaped, with large serrate margins, directed ventrally.
Coloration (Fig. 15 E). Dorsal scutum dark brown uniform, with tubercles and apophyses of ocularium, of area III and tubercles of dorsal scutum sulphuruous yellow.
Female description (Figs. 12 D, 14D). Measurements (n=1). Dorsal scutum; maximum width: 4.3; total length: 4.8; prosoma length: 1.8. Femur IV length IV: 14. Tarsal formula: 6; 14; 8; 9. Body more convex than male. Ocularium with a pair of spiniform apophyses a little larger than those of male, and two pairs of tubercles behind and one pair of anterior apophyses. Area II totally recovered by granules; apophyses of area III larger than male. Posterior margin with a pair of high median apophyses, posteriorly directed. Free tergite II with one small median apophysis spiniform. External apical apophysis of coxa IV reduced and single-branched; internal apophysis absent. Trochanter IV with small internal apical spiniform apophysis; femur IV unarmed and straight, length much smaller than male.
Geographical distribution (Fig. 3 B). Costal Atlantic Rain Forest of São Paulo and southeastern of Rio of Janeiro State.
Note. The type locality, Jacarepaguá, refers to the specimen deposited on MNRJ, mislabeled as “ P. granulosissimus, holotype ”. A second label mention “ Promitobates jacarepagua ”. There is not further data on label on year, locality, collector or identifier. The holotype of P. granulosissimus is a female not coespecific with this material.
