Diagnosis. Males of Eucampesmella iracema sp. nov. differ from all other species of the genus by the prefemoral process containing two robust branches, one located on anterior position, other positioned apically ( Fig. 53). Acropodite broad, apically divided into two small but robust branches (S and AP; Figs 53, 55).

Type material. Holotype: Male from Serra dos Cavalos (8°21’21”S; 36°01’46”W), Caruaru , Pernambuco, Brazil, 1999, A. Giupponi & A.B. Kury coll. ( MNRJ 11648 ).

Description. Male (Holotype, MNRJ 11648). Coloration (long-preserved in 70% ethanol): Head brownish. Antennae white yellow. Body brown and paranota tip whitish. Legs brownish. Body rings: cuticle rough; 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 without projections but the anterior zone between the coxae have a cluster of setae. 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 is rounded projected. Legs brownish, with a dorsal lobe in the prefemur. Telson brown with the posterior margin whitish.

Total length: 53.71. Width total: 8.71. Antennomere lengths (1>7): 0.71; 1.77; 1.60; 1.36; 1.54; 1.48; 0.26. Podomeres lengths (1>7): 0.88; 1.08; 2.21; 1.15; 1.24; 1.62; 0.48. Gonopod aperture, long 2.01, width 3.71. Telson, long 1.59. Gonopod: long 3.07, width 2.80. Coxae: long 1.51, width 2.61. Telopodite: long 2.84, width 1.56.

Gonopods ( Figs 53−55): coxae equivalent to about the length of the telopodite and prominent digitiform (= rectangular, rounded in the corners) in ectal view ( Fig. 55). 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, but not exceeding the acropodite; robust and broad, in dorsal view, except for the terminal branch that is internally curved; an internally curved secondary process arises in the medial portion (PfP; Figs 53, 54). Acropodite elongated, robust and broad; solenomere conducting the prostatic groove that opens on a small sharp projection in the apex of this branch (S; Figs 53−55); Acropodital process rounded and shield shaped, in ventral view (AP; Figs 53−55).

Female. Unknown.

Distribution. Only known for the type locality ( Fig. 67).

Etymology. The species epithet is a reference to the Brazilian literature character “Iracema ” from the book “Iracema ” written by José de Alencar. Noun in apposition.
