Figures 7 , 11 urn:lsid:zoobank.org:act: 5C4BD0F8-892D-4C88-9D0B-24460FE62524 Type material. Male holotype from Nova Xavantina ( 14°40’24”S , 52°21’11”W ), Mato Grosso , Brazil , XI.1949 , Instituto Butantan Expedition coll., deposited in IBSP 59 . Paratype : one male with the same data of the holotype , deposited in IBSP 7786 . FIGURE 6. Arthrosolaenomeris saci n. sp. (holotype, IBSP 2571), dorsal views of anterior (A), midbody (B) and posterior (C) body rings. Scale bars: 2 mm. Left gonopod. (D), mesal view; (E), ventral view; (F), ectal view. Scale bars: 1 mm. Abbreviations: C, cingulum; PfP, prefemoral process; S, solenomere; SPr, secondary process of the prefemoral process. Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: short (about half the length of secondary processes categorized as “elongated”) secondary process of the prefemoral process ( Fig. 7D ) and presence of a lateral row of macrosetae in the gonocoxae, in mesal view ( Fig. 7D ). Description . Male ( Holotype , IBSP 59). Coloration (long-preserved in 70% ethanol): Head and antennae ochre. Body ocher with the edge of the paranota yellow whitish ( Figs 7A–C ). Legs ocher whitish. Telson ocher. Total length: 59.40. Total width: 9.76. Collum, length 2.98, width 9.56 Antennomere lengths (1>7): 0.69; 1.85; 1.50; 1.37; 1.38; 1.55; 0.37. Podomeres lengths (1>7): 0.89; 1.33; 2.84; 1.18; 1.59; 1.99; 0.45. Gonopod aperture, length 1.55, width 3.03. Telson, length 1.68. Gonopod: length 3.17, width 1.88. Gonocoxae: length 0.90, width 1.03. Telopodite: length 3.04, width 0.90. Prefemoral region 1/3 the size of telopodite. Prefemoral process ( Fig. 7D ) length, broad and without indentations, presenting a dorso-basal lobe, starting from an angle of 135°, ascending parallel to the solenomere and partially covering it in mesal view, in the middle part of the process presents a short trianguliform secondary process, acute apex ( Fig. 7D ). Solenomere long and narrow ( Fig. 7F ). Cingulum positioned centroposteriorly ( Fig. 7F ). Apex of the solenomere acute and abruptly descending ( Fig. 7F ). FIGURE 7. Arthrosolaenomeris curupira n. sp. (holotype, IBSP 59), dorsal views of anterior (A), midbody (B) and posterior (C) body rings. Scale bars: 2 mm. Left gonopod. (D), mesal view; (E), ventral view; (F), ectal view. Scale bars: 1 mm. Abbreviations: C, cingulum; PfP, prefemoral process; S, solenomere; SPr, secondary process of the prefemoral process. Female. Unknown. Distribution . Known only from the type locality ( Fig. 11 ). Etymology. The species epithet is a reference of the Brazilian folkloric character “Curupira”. According to the indigenous legend, Curupira is the protector of the Brazilian forests. Noun in apposition.
