 Diagnosis. Males of Eucampesmella macunaima sp. nov. differ from all other species of the genus by the presence of an acute basal branch in prefemoral process (Fig. 42), similar to E. serrana but without any other projection in the apical portion.   
Type material. Holotype: Male from Belém (01°27’21”S; 48°30’14”W), Pará, Brazil, 12-15.ii.2009, A.D. Brescovit coll. (IBSP 3632). Paratypes: one female with same data as for holotype (IBSP 3633); one male and one female from Museu Paraense Emílio Goeldi, Campus de Pesquisa, Belém, 13.i.2011, E.G. Cafofo coll. (MPEG 48); one male and one female from Residencial Jardim Universitário, Belém, 22-31.viii.2016, A.D. Brescovit coll. (MZSP 1159 and MZSP 1160, respectively).  
Description. Male (Holotype, IBSP 3632). Coloration (long-preserved in 70% ethanol): Head brown. Antennae brownish. Body brown and paranota tip yellowish. Body rings: cuticle rough; paranota rounded; ozopore central-posteriorly situated on paranota; peritremata slightly pronounced on the paranota. Stigma oval. Sternite of body ring 4 with one pair of projections; Sternite of body ring 5 with one pair of projections (the former); post-gonopodal sternites with two pairs of triangular projections; Sternite until body ring 9 with the anterior zone between the coxae showing a cluster of setae. Pair of legs on body ring 3 with coxae possessing a rectangular-shaped genital papilla. Gonopod aperture on body ring 7 elliptical, posterior edge with prominent folds, in anal view the posterior margin is projecting and rounded. Legs brownish, with a dorsal lobe on the prefemur. Telson brown with the posterior margin whitish.  
Total length: 52.03. Width total: 6.96. Collum, long, 2.32, width, 6.66. Antennomere lengths (1>7): 0.66; 1.43; 1.31; 1.31; 1.39; 1.36; 0.33. Podomeres lengths (1>7): 0.72; 1.03; 1.87; 0.93; 0.92; 1.42; 0.45. Gonopod aperture, long 1.72, width 2.70. Telson, long 1.32. Gonopod: long 2.82, width 2.44. Coxae: long 1.10, width 1.76. Telopodite: long 2.74, width 1.02.  
Gonopods (Figs 42−44): coxae equivalent to about half the length of the telopodite and prominent rectangular in ectal view (Fig.44). Coxae with a row of macrosetae on the dorsal side. Cannula: hook-shaped. Prefemoral region ventrally developed, about 1/3 length of telopodite; ending in a well-demarcated transition zone (Fig. 44). Prefemoral process long and slender; apex slightly broad divided into two small acute tips; a thin secondary process arises in the medial-basal portion, not surpassing the length of the prefemoral process (PfP; Figs 42, 43). Acropodite elongated, robust and broad; apical portion divided into two large branches: the internal one (=solenomere) conducting the prostatic groove that opens on a small sharp projection in the apex of this branch (S; Figs 42, 44). Acropodital process (AP) covering the solenomere (S) in ventral view, spoon shaped (Fig. 43).  
Female (Paratype, IBSP 3633). Coloration as in male. Posterior margin of vulvae opening presenting a large triangular-shaped epigyne (Fig. 20). Vulvae (Fig. 21) elongated and slender. Total length: 56.54. Width total: 7.76. Posterior margin of the vulvae aperture: 3, 04 width. Vulvae: long 2.45, width 0.72. External valve: long 2.03, width 0.33. Internal valve: long 1.94, width 0.29. Operculum: long 0.37, width 0.45. Lateral margin of the both valves with long setae and densely setose, central setae short and scattered (Figs 21, 22). Operculum small (OP, Figs 21−23).
