Comments.

In a recent contribution, Ott et al. (2015) extend the distribution of Neonella minuta   toward Rio Grande do Sul (Brazil), which was originally only known endemic to Buenos Aires (Argentina) by Galiano (1965). Our present work enhances the geographical distribution of this species, representing the westernmost record so far ( Córdoba province, Central Argentina).

Ecology of the collected species.

The three species of Neonella   were collected during the spring and the summer but were not detected in the winter samples. They were found in the lower strata of vegetation (0 to 35 cm), consisting mainly of grasses and forbs. Neonella acostae   was collected both within the urban environment (Fig. 1A, B) and in more natural sites on the periphery of the city (Fig. 1A, C), while Neonella montana   and Neonella minuta   were mostly collected from more natural sites with dense vegetation on the city periphery (Fig. 1A, C). Based on Cole’s index ( 1949), Neonella acostae   was negatively associated with Neonella minuta   (-0.44 ± 0.42; mean association ± standard error) and Neonella montana   (-0.13 ± 0.11), suggesting moderately dissimilar habitat disturbance tolerances because Neonella acostae   was collected at a wider range of sites in terms of plant cover, or alternatively a moderate degree of interspecific competition because they occasionally occurred at the same site. Cumming and Wesolowska (2004) explained high Salticidae   richness in small suburban areas as a result of strong host-plant associations. More detailed studies of microhabitat use should be carried out to confirm these explanations. Neonella minuta   and Neonella montana   were not significantly associated (0.1 ± 0.11), suggesting independent occurrences of the species.
