Diagnosis. Males of Eucampesmella lartiguei differ from all other species of the genus by having an apical fold on the prefemoral process, in mesal and ventral view; by the short process at the prefemoral process, at the middle and ventrally pointed, in mesal and ventral view ( Figs 32, 33). This process is also observed in E. brascubas sp. nov., but differing by the size, being longer and pointed anteriorly in E. brascubas sp. nov.

Distribution. Holotype labeled only as “ Pernambuco ”, without exact locality; also known in states of Ceará, Rio Grande do Norte, and Alagoas ( Fig. 66).

Justification of synonymy. The original description made by Schubart (1956) for Leptodesmus lartiguei ferrii was based on single male (45 mm length, 7.6 mm wide). Schubart also noted that the species agrees with Leptodesmus lartiguei ( Silvestri, 1897) in all somatic characters. Through the examination of the type material Eucampesmella l. ferri and analysis of the original work and drawings of Eucampesmella l. lartiguei provided by Silvestri (1897), as well as the accurate exam of several specimens identified by Otto Schubart, we concluded that the males of both nominal species present complete agreement when considering the body shape and the morphology of the gonopod. A slight difference in the form of the acropodital apex is here treated as just an intraspecific variation. Therefore, it is proposed herein E. lartiguei ferrii as a junior synonym of E. lartiguei lartiguei .

Remarks. The type-locality of Leptodesmus lartiguei ferrii was originally cited as Alto Bonito in the South of Cachoeira de Paulo Afonso (Paulo Afonso Falls), municipality of Glória, Bahia state ( Schubart 1956: 423). After checking local gazetteers, we found that Alto Bonito refers to an area belonging to the municipality of Delmiro Gouveia, Alagoas, and not in Bahia, as referred in the original description. It is important to note that Paulo Afonso Falls is located in Paulo Afonso, currently a municipality in Bahia. This region is located at the border of the states of Bahia and Alagoas, surrounding by the Paulo Afonso Hydroelectric Complex, a system of dams and power plants on the São Francisco River.
