 Diagnosis. Males of Eucampesmella lalla sp. nov. differ from all other species of the genus by the prefemoral process with a small lateral spine on the middle region of the process (Figs 61, 62). Just above the median region of the prefemoral process, on the inner margin, there is an irregular zone with some indentations (Fig. 61).   
Type material. Holotype: Male from Parque das Dunas (5°50’03”S; 35°11’25”W), Natal, Rio Grande do Norte, Brazil, 02.II.2002, Fernando coll. (IBSP 1378). Paratypes: One female from the same date and locality (IBSP 1378).  
Description. Male (Holotype, IBSP 1378). Coloration (long-preserved in 70% ethanol): Head ocher. Antennae yellow-

ish white. 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 two pairs of projections, the former ones are larger and rounded-shaped, the latter ones are triangular; Sternite of body ring 6 with two pairs of small triangular projections in the base of the coxae; post-gonopodal sternites with two pairs triangular projections; Sternite until the body ring 9 with the anterior zone between the coxae showing a cluster of small 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 projecting margin is rounded. Legs yellowish, with a dorsal lobe on the prefemur and tibia, some legs with granules. Telson brown with the posterior margin whitish.  
Total length: 61.16. Width total: 10.34. Antennomere lengths (1>7): 0.67; 1.80; 1.36; 1.43; 1.64; 1.33; 0.22. Podomeres lengths (1>7): 0.65; 1.46; 2.45; 1.34; 1.55; 1.56; 0.48. Gonopod aperture, long 2.60, width 4.57. Telson, long 1.00. Gonopod: long 3.93, width 3.90. Coxae: long 1.88, width 2.94. Telopodite: long 3.67, width 1.77.  
Gonopods (Figs 61−63): coxae equivalent to about the length of the telopodite and prominent digitiform (= rectangular, with rounded corners) in ectal view (Fig. 63). Coxae with a row of macrosetae on the dorsal side. Cannula: hook-shaped. Prefemoral region ventrally developed, about 1/3 length of the telopodite; ending in a well-demarcated transition zone. Prefemoral process long, slightly exceeding the length of the acropodite; broad, in dorsal view; indentation border is present in the sub-apical portion on the external margin of the process; a small spine-shaped secondary process arises in the medial portion (PfP; Figs 61, 62). Acropodite elongated, robust and broad; apical portion divided; Solenomere conducting the prostatic groove that opens on a conspicuous acute projection; solenomere robust and rounded shaped (S; Figs 61−63); Acropodital process more slender than the solenomere, sub-oval in ventral view (AP; Figs 61−63).  
Female (Paratype, IBSP 1378). Head and body dark brown, paranota tip yellowish. Posterior margin of vulvae opening presenting a small dome-shaped epigyne. Vulvae (Fig. 64) elongated; not straight (=curved to the external side; “C-shaped”). Total length: 63.14. Width total: 9.28. Posterior margin of the vulvae aperture: 2, 93 width. Vulvae: long 1.93, width 1.15. External valve: long 1.91, width 0.86. Internal valve: long 1.49, width 0.69. Operculum: long 0.28, width 0.46. Latero-posterior margin of the both valves with long setae and densely setose, central setae shorter and scattered; a depression occurs along all the central portion of both valves (Fig. 65). Operculum small (OP, Figs 64, 65).  
Distribution. Only known for the type locality (Fig. 67).  
Etymology. The species epithet is taken as a noun in apposition honoring the chilopodologist Laura Del Latte, nicknamed “Lalla ”, for her contributions to science and a very important person in life for the third author.
