“…Finally, in those mygalomorph spiders that live in funnel-webs, also distantly related to lycosids, ballooning is not reported according to the review of Buzatto et al (2021). Instead ballooning has been reported in non-funnel-web mygalomorphs, and the pre-ballooning behaviour involved is dropping on dragline (Buzatto et al, 2021;Coyle, 1983;Ferretti et al, 2013;Kuwada-Kusunose et al, 2016). Thus, our study is the first to evaluate aerial dispersal in a funnel-web lycosid, and probably also the only one to do so in any funnel-web spider.…”

“…In terms of dispersal distance, studies carried out in the family Lycosidae consider the presence of tip‐toeing as a representative element of the existence of long‐range dispersal (Bonte et al., 2006; Richter, 1970), but dropping on dragline has been suggested, by some studies, as a mechanism quite inefficient since most spiders land very close to where they took off and only occasionally manage to travel greater distances (Coyle, 1983; Ferretti et al., 2013; Kuwada‐Kusunose et al., 2016). However, it is possible that by repeating this behaviour successive times, the spiderlings could cover much longer distances (Buzatto et al., 2021; Tolbert, 1977) and therefore could achieve dispersal of greater distances than they would reach in an ambulatory way.…”

Ballooning is a mechanism of aerial dispersal present in some groups of spiders. By releasing silken threads that are blown by the wind, spiders can travel long distances through the air. Aglaoctenus lagotis is a wolf spider that lives its entire life associated with a funnel‐web, despite the wandering habit that characterizes species in this family. We can find two forms of the species in Uruguay, one of them a strict inhabitant of grasslands of Uruguay. The high habitat specificity and the spiderlings observed surrounding the maternal web suggest a low aerial dispersal capacity in this species. In this study, we tested whether A. lagotis spiderlings are capable of dispersing by ballooning. We conducted laboratory and field experiments during the day and night, to record the occurrence of ballooning and typical behaviours that precede ballooning. We recorded ballooning both in the laboratory and in the field, and it was more frequent during the day. Although it has been reported repeatedly in species from this family, we never observed the pre‐ballooning tip‐toeing behaviour in A. lagotis. Ballooning was preceded by dropping on dragline, considered a behaviour that could generate aerial dispersion of lesser distance than that generated by the tip‐toeing. In this paper, we shall discuss the implications of this form of aerial dispersal, considering that the species analysed is a web wolf spider.

Defining species units provides basic information for a wide range of biological research, for example, studies of evolution, biodiversity, and conservation. However, species delimitation can be challenging, especially during the earliest stages of divergence or speciation, when both molecular and morphological characters exhibit low levels of differentiation (de Queiroz, 2007). Integrative approaches to delimiting species, which combine morphological and molecular evidence, have the potential to address such issues in many taxa, including spiders
