FEMALE. (1 specimen measured)

Dorsal shield 320 long, 168 wide; j1 20, j3 30, j4 20, j5 19, j6 23, J2 28, J5 7, z2 30, z4 29, z5 22, Z1 30, Z4 47, Z5 55, s4 36, S2 38, S4 24, S5 17, r3 30, R1 25. Distances between st1-st3 50, st2-st2 50 and st5-st5 60, ventrianal shield 95 long, 63 wide at level of ZV2 and 53 wide at level of anus. Preanal pores not distinguishable; JV5 89 (88–90). Peritreme extending forward to level of j1. Not possible to measure movable and fixed digits and to count their teeth. Calyx trumpet-shaped, 15 long. Macroseta sharp: StIV 25. Chaetotaxy: genu II - 1, 2/0-2/1, 1; genu III - 1, 2/1-2/0, 1.

Specimen examined. Lambayeque: Chiclayo — Monsefú (06°32'19''S, 79°52'45''W), 6-VIII-2006, on Brugmansia arborea (1Ψ).

Previous records. Peru- Lima ( El-Banhawy 1979).

Remarks. The single female collected in this study has seta R1 1.4 times as long as mentioned in the original description of this species. In addition, differently from what was mentioned in the original description of this species, the chaetotaxy of genu III of the specimen collected is 1, 2/1-2/0, 1, instead of 1, 0/1-2/1, 2. According to Chant & McMurtry (2003), N. peruanas is the sole species in the peruanus [sic] species group, characterized, among other aspects, by having elongate ventrianal shield (ratio length/width = 2.0); in the specimen collected in this study that ratio is 1.5.
