Diagnosis. Four areas on dorsal scutum. Posterior margin with one pair of median spiniform apophyses, smaller than the ocularium. Free tergite III with one pair of small spiniform apophysis or unarmed. It is closely related to P. ornatus and P. difficilis, distinguished by tubercles and granules of dorsal scutum yellowish, with circular patches of same color around them.
Male redescription. Measurements (n=6). Dorsal scutum; maximum width: 3.6–4.5 (3.6); total length: 3.5– 4.8 (3.5); prosoma length: 1.5–1.9 (1.5). Leg IV; length of external apophysis of coxa: 0.9–1.6 (1.0); femur IV length: 25.5–46.4 (32.1). Tarsal formula: 8; 13–16 (13); 8–9 (8); 8.
Dorsum (Figs. 4 C, 7C). Anterior margin of prosoma with frontal hump with scattered small tubercles and with one pair of tubercles on lateral margins. Ocularium with two high rounded apophyses, divergent and directed anteriorly, and small tubercles next to them. Prosoma with tubercles behind ocularium and arranged in “V”. Area I with two median tubercles and one row of small tubercles up to the posterior groove. Area II with scattered tubercles. Areas III with a pair of spiniform apophyses (apex rounded) and one row of tubercles up to the posterior groove. Area IV with two enlarged median tubercles, and one row of small tubercles. Lateral margin of dorsal scutum with few tubercles which are placed from ocularium to area III–IV. Posterior margin with one row of tubercles increasing in size to the corners and two median spiniform apophyses. Free tergites I and II unarmed with small scattered tubercles. Free tergite III unarmed or with median spiniform apophysis. Anal operculum unarmed.
Chelicera. Segment I with two small tubercles; II unarmed.
Pedipalp. Trochanter with a small ventral spine. Femur with a small ventro-basal spine and one enlarged, subapical, prolateral spine. Tibia setation: mesal IiIi; ectal IiIi. Tarsal setation: mesal IIi; ectal IiIi.
Venter. Coxa I with one median row of five tubercles, three apical tubercles and small scattered granules; trochanter I with one median and one apical tubercles. Coxa II with median row of nine small tubercles and two apical tubercles; trochanter II with median tubercle. Coxa III with small tubercles, roughly distributed in rows and one posterior row of tubercles; trochanter III with one median tubercle. Coxa IV with small scattered tubercles and four tubercles on posterior margin; genital area and anal operculum with small scattered granules; free sternites I–III with a row of granules.
Legs (Fig. 9 C). Coxa I with a posterior dorso basal apophysis; II with one anterior dorso basal and one posterior; IV with few high tubercles, with two or three small internal spiniform apophysis and one external apical bifid apophysis. Trochanters I–III with small scattered tubercles; IV with a dorsal subapical apophysis, an external basal apophysis, and a small internal spinform apophysis. Femur IV straight with minute tubercles, more than 12 times longer than dorsal scutum length.
Penis (Fig. 16 G, H, I). Ventral plate with a dorsal median transversal depression, lateral convex, apex straight and distal margin corner rounded and directed ventrally; three pairs of long distal setae; three pairs of basal setae arranged in “V” and one pair of basalmost small ventral setae. Stylus unarmed, apex straight and swollen. Ventral process almost parallel to the stylus in lateral view, truncus short, spoon-shaped apex, with long serrate margins directed ventrally.
Coloration (in ethanol). Dorsal scutum, chelicerae and pedipalps dark brow; tubercles and granules yellowish with a circular patch on of same color around them. Apophyses of ocularium, area III and tubercles of posterior margin of dorsal scutum yellowish. Apophyses of area III and apex of external apophysis of coxa IV blackish.
Female redescription (Figs. 11 C, 13C). Measurements (n=8). Dorsal scutum; maximum width: 4.2–4.7; total length: 3.8–4.9; prosoma length: 1.4–1.8. Femur IV length IV: 10.2–14.1. Tarsal formula: 5–7; 12–15; 8–9; 8–9. Apophyses of area III larger than those on males. Posterior margin of dorsal scutum with one pair of high median pointed apophyses, directed posteriorly. Free tergites II and III with one median spiniform apophysis. External apical apophysis of coxa IV strongly reduced and single-branched, internal absent. Trochanter IV unarmed or with small internal apical spiniform apophysis; femur IV shorter than male.
Geographical distribution (Fig. 3 A). East of Paraná and southeastern of São Paulo States.
Remarks. The specimens studied of Promitobates hatschbachi show a wide variation in number of tubercles on dorsal scutum, even in same locality. The study of a large sample of this species (79 specimens) lead us to conclude P. mendax is within this variation, justifying its synonymy. Remarkable intraspecific variation has been observed in some species of gonyleptids (see Kury 1990a; Bragagnolo & Pinto da Rocha 2009; Hara & Pinto-da-Rocha 2010).
