Type material. BRAZIL. Santa Catarina: São Bento do Sul (Ano Bom), 26°22’S – 49°13’W, 3.IV.1999, R. Pintoda-Rocha & R. Bérnils leg., 3 holotype, 3 3 and 4 Ƥ paratypes ( MZSP 18635); Paraná: São José dos Pinhais (Usina de Guaricana), 28.IV.1987, R. Bérnils leg. 1 3 ( MHNCI 6129); idem, 16.II.1988, R. Pinto-da-Rocha leg., 1 Ƥ and 1 3 ( MNRJ 18796).

Etymology. The epithet refers to a kind of beer of high fermentation.

Diagnosis. Resembles Promitobates trapista sp. n. by the external apophysis of coxa IV single-branched. Recognized by ocularial armature (two tubercles), free tergite II with a pair of spiniform apophyses and coloration of dorsal scutum and legs, yellow with black points.

Male description. Measurements (n=10). Dorsal scutum; maximum width: 3.8–4.4 (3.9); total length: 4.1– 4.3 (4.1); prosoma length: 1.6–1.7 (1.6). Leg IV; length of external apophysis of coxa: 0.9–1.4 (1.0); femur IV length: 16.1–18.9 (16.6). Tarsal formula: 7; 15–16 (15); 8–10 (8); 9–10 (9).

Dorsum ( Figs. 6 View FIGURE 6 A, 8C). Anterior margin of prosoma unarmed, including frontal hump. Prosoma with two small tubercles behind ocularium. Ocularium with two rounded tubercles. Area I with two median tubercles and small tubercles up to the posterior groove. Area II with small tubercles scattered distributed. Area III and IV partially fused, III with a pair of pointed apophyses posteriorly directed. Lateral margin smooth. Posterior margin of dorsal scutum with one row of spiniform tubercles, increasing in size up to the corners and two median apophyses. Free tergites I and II and anal plate unarmed; tergite III with one pair of paramedian spiniform apophyses.

Chelicera. Segment I with two setiferous tubercles; II unarmed.

Pedipalp. Trochanter with a small ventral spine. Femur with a small ventro-basal spine and one, larger, prolateral apical spine. Tibia setation: mesal IiIi; ectal IiIi. Tarsus setation: mesal IIi; ectal IiIi.

Venter. Coxa I with median row of five setiferous tubercles and two apical tubercles; trochanter I with median tubercle. Coxa II with median row of eight small setiferous tubercles and two apical tubercles; trochanter II with median tubercle. Coxa III with small setiferous tubercles, roughly distributed in rows, the anterior one and posterior one, increasing distally; trochanter III with median tubercle. Coxa IV with granules scattered and four tubercles on posterior margin; genital area unarmed; free sternites with one row of granules; anal operculum with small granules scattered.

Legs ( Fig. 10 View FIGURE 10 C). Coxa I with posterior dorso basal apophysis; II with one anterior dorso basal apophysis and one posterior; coxa III unarmed; coxa IV with few tubercles, three internal apical spiniform tubercles and one external apical short apophysis, directed ventrally and one basal tubercle. Trochanter I–III with small scattered tubercles. Trochanter IV with two external apophysis, the basal rounded. Femur IV long, straight and unarmed.

Penis ( Fig. 18 View FIGURE 18 D–F). Ventral plate convex, apex straight; three pairs of long subapical setae; three pairs of basal setae, arranged in “V” and one pair of ventral basal setae. Stylus unarmed, slightly curved. Ventral process almost parallel to the stylus, apex spoon-shaped, with serrate margins directed ventrally.

Coloration ( Fig. 15 View FIGURE 15 D). Dorsal scutum yellow with black points; Chelicerae, Pedipalps, coxa and trochanter I– III dark-yellow; apophyses of area III and apice of external apophysis of coxa IV black.

Female description ( Figs. 12 View FIGURE 12 B, 14B). Measurements (n=9). Dorsal scutum; maximum width: 4.1–4.8; total length: 4.1–4.7; length of prosoma: 1.5–1.7. Femur IV length IV: 10.6–12.6. Tarsal formula: 6; 13–16; 10; 8–10. Body more convex than male. Posterior margin of dorsal scutum unarmed. Free tergite II with a pair of small tubercles or unarmed; free tergite III with one pair of spiniform apophysis. Coxa IV with external apical spiniform apophysis, internal apophysis absent. Trochanter IV unarmed; femur IV shorter than male.

Geographical distribution ( Fig. 3 View FIGURE 3 A). Atlantic rain Forest of northern Santa Catarina and southeastern of Paraná States.
