Solaropsis rugifera juruana Ihering 1905: 456 .

Solaropsis (Psadara) monile peruviana Haas 1951: 528 , fig. 114. [new synonym]

Material examined. Brazil • Acre, Porto Acre , HFR; 09°45′21″S, 067°40′06″W; 12.X.2018; M. Lima and W. Lima leg.; 1, MZSP 150068 (ex UFAC 1006 ) • same locality; 09°45′03″S, 067°40′21″W; 10.I.2019; W. Lima and L. Guimarães leg.; 1, MZSP 150069 (ex UFAC 1058 ) • same locality; 09°45′37″S, 067°38′51″’W; 07.IX.2018; M. Lima and W. Lima leg.; 1, UFAC 986 • same locality; 09°45′03″S, 067°40′20″W; 23.VIII.2018; W. Castro leg.; 1, UFAC 1064 .

Identification. The flattened spire, compact overall shape, round and proportionately large aperture, and coloration pattern with two dark, dashed, spiral lines, compare well with S. juruana (syntypes MZSP 1364; Fig. 6D–F). We stress that S. monile peruviana Haas, 1951 (holotype FMNH 30928, Field Museum of Natural History, Chicago, USA; Fig. 6G–I) is also indistinguishable from S. juruana and is, thus, considered herein as its junior synonym.

Solaropsis peruviana has been described from Sahuayaco, Peru (800 m a.s.l.), circa 600 km southwest of HFR. As such, the geographic distribution of S. juruana is increased to encompass western Amazonas, Acre, and southeastern Peru.

Geneticdata. Spm #1: CO1, MT 080615 ; 16S, MT 080823 ; ITS2+28S, MT 080839 ; from voucher specimen UFAC 779 (Acre, Rio Branco, Bairro Universitário; E. Alencar leg., 9. VI.2017). Spm #2: CO1, MT 080616 ; 16S, MT 080813 ; ITS2+28S, MT 080840 ; from voucher specimen UFAC 1091 (Acre, Rio Branco, Bairro Universitário, 09°56′51″S 067°53′11″W; G. Pedrosa leg., 14. VI.2019).

Type locality. Juruá River, Amazonas state, Brazil.

Distribution. Western Amazonas state, Brazil ( Simone 2006).

Remarks. The present species is also classified in the ge- nus Psadara Miller, 1878 in current literature (e.g., Simone 2006). A recent molecular analysis, however, has shown that Psadara is synonymous with Solaropsis ( Calcutt et al. 2020) .
