Larval shell with about 2.25 whorls, 380 µmwide, 430 µmin height; smooth, transition to teleoconch marked by an almost indistinct incremental scar. Teleoconch with about 5 whorls, slightly sinuous outline, convexity confined to the lower region of each whorl; suture shallow, slightly impressed, sloping; subsutural zone about 1/4 of the height of the whorl; surface glossy and smooth; incremental scars weak, appearing at irregular intervals, frequent. Last whorl about 60% of the shell length; base elongated with slightly rounded outline. Aperture high, narrow, pear shaped, acute posteriorly and rounded anteriorly; outer lip thin, almost straight, opisthocline, slightly projecting near the suture and slightly retracting in the distal region; inner lip sinuous, sloping and well demarcated. Not umbilicate. Shell vitreous, or whitish, with a brownish spiral band at the suprasutural region of the teleoconch, last whorl with a duplicate spiral band in dorsal view.  Measurements. HolotypeMNRJ 35202†, 7.25 whorls, SL= 5.9 mm; BWL= 3.6 mm; AL= 2.4 mm; SW= 1.6 mm; AW= 1.0 mm. ParatypeMNRJ 35216†, 8 whorls, SL= 6.8 mm; BWL= 4.2 mm; AL= 2.7 mm; SW= 1.9 mm; AW= 1.3 mm.   Remarks.All typesof the present species were destroyed; however, it has consistent shell features that allow the description as a new species, and the figures provided here are sufficient for its recognition.   Eulima cracentis  sp. nov.presents brownish spiral bands on the teleoconch ( Figure 7A–C), which is a common feature in the genus.  Eulima cracentis  sp. nov.can be distinguished from  E. bifasciata, a shallow water species of the western Atlantic, by the presence of a single brownish spiral band on the teleoconch, except on the last whorl ( Figure 7C), while  E. bifasciatashows two brownish spiral bands per whorl (see Lamy & Pointier 2017: plate 88, figure 1a, b). Furthermore,  E. cracentis  sp. nov.has more convex teleoconch whorls and a more inflated body whorl.   Eulima cracentis  sp. nov.can also be distinguished from  E. ephamilla( Figure 5A–E) and  E. psila( Figure 6A–M) by the presence of the brownish spiral band at the teleoconch, more convex teleoconch whorls and the relatively higher aperture in relation to the body whorl length (ratio AL/BWL= 0.67, 0.60 and 0.63, respectively). Furthermore,  E. cracentis  sp. nov.has a smaller number of protoconch whorls (2.25 vs.3.5) and a wider protoconch ( 380 µm vs. 320 µm) than  E. psila. The shell figured by Lamy & Pointier (2017: plate 88, figure 4a–b) of an unnamed species of  Eulimacollected in Guadeloupeat 200 mresembles  E. cracentis  sp. nov., but has a narrower protoconch and teleoconch, and seems to have just a single spiral band on the body whorl.  Geographical distribution.  Brazil: Ceará, Pernambuco, Alagoas.  Bathymetric distribution.From 206 mto  465 m. 3041480311 [334,790,1338,1365] MNRJ 13 464 MNRJ 35202 1 holotype 3041480347 [802,1432,1338,1365] MNRJ 13 464 MNRJ 23225 1 paratype 3041480371 [151,1432,1374,1403] 2001-11-10 MNRJ 206 -4.2505555 Nordeste 21 -37.210278 13 464 MNRJ 35216 1 Ceara paratype 3041480401 [151,1303,1410,1439] 2001-12-18 MNRJ 452 -9.333333 Nordeste 21 -34.983334 13 464 MNRJ 35265 1 Alagoas paratype 3041480316 2000-03-25 RV Natureza Brazil 465 -8.701667 Nordeste 21 -34.735 Off 13 464 1 Pernambuco holotype 3041480329 [524,933,655,681] Brazil Ceara 15 466 1 Ceara
