 Diagnosis. Males of Eucampesmella capitu sp. nov. differ from all other species of the genus by the apical portion of prefemoral process divided (Figs 45, 47), similar to E. pedrobala sp. nov., but with anterior branch longer than the posterior, while in E. pedrobala sp. nov. the two branches have the same length (Fig. 45).   
Type material. Holotype: Male from Paraíba, Brazil, 1999, A. Giupponi & A.B. Kury coll. (MNRJ 11959). Paratypes: One male with same data as for holotype (MNRJ 30172).  
Description. Male (Holotype, MNRJ 11959). Coloration (long-preserved in 70% ethanol): Head brownish. Antennae white yellow. Body brown and paranota tip whitish. Legs brownish. Body rings: cuticle rough, with a pattern of slightly raised squares; paranota with posterior edges rounded; ozopore posteriorly situated on paranota. Stigma oval. Sternite of body ring 4 with one pair of projections; Sternite of body ring 5 with two pairs of projections, the former ones are rectangular and the latter ones are triangular; Sternite of body ring 6 with an anterior pair of triangular projections. Pair of legs on body ring 3 with coxae possessing a rectangular-shaped genital papilla, and pairs of legs on body rings 5 to 17 with two pairs of slightly triangular projections between coxae. Gonopod aperture on body ring 7 elliptical, posterior edge with prominent folds, in anal view the posterior margin without any projection. Legs brownish, with a dorsal lobe in the prefemur. Telson brown with the posterior margin whitish.  
Total length: 43.51. Width total: 6.75. Antennomere lengths (1>7): 0.51; 1.13; 1.29; 1.32; 1.18; 0.26. Podomeres lengths (1>7): 0.69; 0.93; 1.99; 0.84; 0.91; 1.23; 0.46. Gonopod aperture, long 1.67, width 2.65. Telson, long 1.15. Gonopod: long 2.15, width 2.22. Coxae: long 0.99, width 1.91. Telopodite: long 2.04, width 1.09.  
Gonopods (Figs 45−47): coxae equivalent to about the length of the telopodite and prominent digitiform (= rectangular, with rounded corners) in ectal view (Fig.47). 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. Prefemoral process long; broad, in dorsal view, except for the terminal branch; a thin and small secondary process arises in the medial portion (PfP; Figs 45, 46). Acropodite elongated, robust and broad; apical portion divided into two large branches: solenomere conducting the prostatic groove that opens on a small sharp projection in the apex of this branch (S; Fig. 47). Acropodital process (AP) subtriangular shaped in ventral view (Fig. 46).  
Female. Unknown.  
Additional material examined. BRAZIL: Piauí: Serra da Capivara (8°46’39”S; 42°37’03”W), 1 male, 10.ii-03.iii.2013, R. S. Recoder coll. (IBSP 3750).  
Distribution. Known from states of Piauí and Paraíba (Fig. 67).  
Etymology. The species epithet is a reference to the Brazilian literature character “Capitu ” from the book “Dom Casmurro” written by Machado de Assis. Noun in apposition.
