MONTUCARIS DISTINCTA SP. NOV. (FIGS 1–29) Material examined South Atlantic Ocean off Brazil, between 22°38′S / 40°27′W and 22°40′S / 40°24′W; fine silt bottoms, 619– 778 m depth; February–March 2001. Holotype : Brooding female (oostegites fully developed, setose), body length (BL) 5.30 mm (MSUSP Reg. no. 17045). Female paratypes : Fifty-four brooding specimens, of which 18 measured: BL 4.63, 5.95, 5.70 and 5.23 mm [MSUSP Reg. no. 17046] and 5.51, 5.45, 4.60, 5.26, 4.80, 5.04, 4.60, 4.75, 5.43, 5.17, 5.03, 5.10, 5.08 and 5.43 mm (BMNH Reg. nos. 2005.401–410]. Two preparatory specimens (with oostegite buds), of which one measured, BL 3.81 mm (BMNH Reg. nos. 2005.411– 412]. Seven preparatory specimens (oostegites with setation not fully developed), of which two measured: BL 4.45 and 4.49 mm (BMNH Reg. nos. 2005.413– 419]. Two brooding specimens prepared for SEM and one dissected for study of musculature. Male morph-I paratypes (see description below): Seven specimens, of which one measured, BL 3.70 mm with P1 and P3–P4 missing, P2 and uropods both with distal part of endopod missing (MSUSP Reg. no. 17047). One specimen with PL1 – PL5 dissected, rest of body in vial; body size not determined owing to damage to specimen. One specimen used for SEM observations. Male morph-II paratypes (see description below): One specimen BL 3.88 mm with well-preserved P7, pleopods, uropods and telson; P1–P4 with distal portion of endopod missing; P5–P6 missing except coxa and proximal part of basis. One specimen partially dissected with pleopods 3–5 loose in vial, PL1–2 accidentally lost; P1, P5, PL1–5 and uropods well preserved; P2–P4 and P6 with distal portion missing; P7 missing; body size not determined due to damage to specimen, not measured, well preserved, dissected for study of musculature (BMNH reg. nos. 2005.430–432). Juvenile male paratypes (pleopods not fully developed): Specimen BL 3.64 mm, with P1–P3 with distal parts missing, P4 and P6 missing, and exopods of uropods missing. One damaged specimen (body anterior to 5th ...
