Furthermore, the pronotum of specimens presented by Ribeiro-Ferreira & Froehlich (2001)and Froehlich (2003)is characteristically whitish medially, which differs in part from the individuals studied here. Some specimens collected in TocantinsState have white band in the middle of pronotum and other have ochraceous stripes and rugosities in this portion. The penial armature is similar to that presented in Ribeiro & Rafael (2009), which is rounded apically. In Ribeiro-Ferreira & Froehich (2001), the apical portion of penial armature is tapered. The female of  A. marlieristudied here has paramedial lobes of subgenital plate larger than lateral lobes, and median notch deeper than sublateral notch; which differs from Ribeiro & Rafael (2009). The egg is oval ( Fig. 4D), 0.22 x 0.3 mm. This is the first record of this species for TocantinsState. This species has been recorded from Amazonas(Manaus, Novo Airão, Barcelos, Humaitá), Pará(Serra Norte), Maranhão(Imperatriz) and Mato Grosso(Chapada dos Guimarães) States ( Ribeiro & Rafael 2009). 2234217729 [636,1127,607,632] 2018-03-27 2018-03-28 2018-03-27 CEUFT 5 360 2 2 2234217725 2018-03-28 2018-03-29 2018-03-28 CEUFT 5 360 2 1 1 2234217736 2018-03-27 2018-03-28 2018-03-27 CEUFT Ribeirao Taquarucu Grande Palmas Cachoeira do Evilson 5 360 2 1 1 2234217735 [409,931,716,741] 2017-10-18 2017-10-19 2017-10-18 MLSR, ASF, CEUFT 5 360 1 1 2234217717 [942,1432,716,741] 2017-10-18 2017-10-19 2017-10-18 MLSF, ASF, INPA 5 360 1 1 2234217728 [151,675,751,776] 2017-10-18 2017-10-19 2017-10-18 MLSR, ASF, CLBA 5 360 1 1 2234217723 [690,1261,751,776] 2017-10-19 2017-10-20 2017-10-19 MLSR, ASF, CEUFT 5 360 2 2 2234217716 2017-10-19 2017-10-20 2017-10-19 MLSR, ASF, INPA 5 360 1 1 2234217732 [533,1072,788,813] 2017-10-19 2017-10-20 2017-10-19 MLSR, ASF, CLBA 5 360 1 1 2234217722 2017-09-19 2017-09-22 2017-09-19 MLSR, ASF 5 360 3 2 1 2234217738 [548,660,824,848] 2017-09-19 2017-09-22 2017-09-19 CEUFT true 5 360 1
