“…In Ch. It has also evolved once in the lycosids (Stefani et al, 2011a) and once in the uloborids, although this report awaits confirmation (cited in Downes, 1995). ferox offspring only feed on trophic eggs before consuming their mother .…”

While most spiders are solitary and opportunistically cannibalistic, a variety of social organisations has evolved in a minority of spider species. One form of social organisation is subsociality, in which siblings remain together with their parent for some period of time but disperse prior to independent reproduction. We review the literature on subsocial and maternal behaviour in spiders to highlight areas in which subsocial spiders have informed our understanding of social evolution and to identify promising areas of future research. We show that subsocial behaviour has evolved independently at least 18 times in spiders, across a wide phylogenetic distribution. Subsocial behaviour is diverse in terms of the form of care provided by the mother, the duration of care and sibling association, the degree of interaction and cooperation among siblings, and the use of vibratory and chemical communication. Subsocial spiders are useful model organisms to study various topics in ecology, such as kin recognition and the evolution of cheating and its impact on societies. Further, why social behaviour evolved in some lineages and not others is currently a topic of debate in behavioural ecology, and we argue that spiders offer an opportunity to untangle the ecological causes of parental care, which forms the basis of many other animal societies.

“…Moreover, individuals of Misiones province (Northern Argentina) have yet another sexual repertoire (M. González, unpubl. data), different from those reported for CA (González et al ., ) and Brazilian (Stefani et al ., ) populations, suggesting a mosaic of divergences within A. lagotis that needs further investigation. This does not preclude the existence of pronounced intraspecific variation – suggested by Santos & Brescovit () for A. lagotis – within each form.…”

“…Thus, each male was placed in the basal end of the ‘T’, exposing him to the silk threads of both females at the same time. Each trial lasted for 1 h, a time period considered sufficient in similar studies of lycosids (Aisenberg, Baruffaldi & González, ; Stefani et al ., ). We registered first male choice (when the male turned at one corner of the T‐shape device), time spent in the chosen arm (permanence), and time spent by the male to make the decision (choice latency).…”

“…() described different sexual repertoires in two distant populations of A. lagotis (south Uruguay and central Argentina), both of which were dissimilar to the description published by Stefani et al . () for populations from Brazil. The most representative courtship acts in southern Uruguay were web stretching, striding forward, and foreleg elevation, whereas in central Argentina they were alternate waving, web stretching, and leg tapping.…”

“…Its taxonomic status has received several changes (Santos & Brescovit, ), but currently it is the species with the widest geographical distribution of the small South American genus Aglaoctenus (from Uruguay to Venezuela) (Piacentini, ). Previous publications on A. lagotis have described sexual behaviour (Stefani et al ., ), oviposition and postembryonic development (Stefani & Del‐Claro, ), and the effects of habitat fragmentation (Stefani & Del‐Claro, ) in Brazilian populations. Additionally, Santos & Brescovit () characterized A. lagotis as a highly variable species, although no interpopulation studies were reported prior to González et al .…”

Aglaoctenus lagotis (Lycosidae: Sosippinae) is a spider that, in contrast to the predominant wandering habit of the family, constructs funnel webs. The species is widely distributed throughout the Neotropics and is credited with high levels of intraspecific variation. Here, we evaluate whether reproductive isolating barriers operate between some populations of A. lagotis. We used heterotypic encounters between individuals from two distant localities: southern Uruguay (SU) and Central Argentina (CA). Additionally, we used spiders from an intermediate locality, western Uruguay (WU), where both forms of the species overlap (SU.WU was used to describe individuals from WU reminiscent of those from SU; and CA.WU was used to describe individuals from WU reminiscent of those from CA). No copulations occurred between SU and CA individuals, whereas a single and atypical copulation occurred between SU.WU and CA.WU individuals. Attacks (only by females on males) were rare. In tests of choice based on silk cues, SU males did not prefer homotypic cues but almost did not court CA females, whereas CA males preferred homotypic cues but usually courted heterotypic females. These findings, with a previously reported temporal asynchrony between populations, suggest the occurrence of reproductive isolation between both spider forms and a speciation process favoured by the wide distribution and plasticity of the species. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, 114, 646–658.
