“…Ant larvae show striking diversity in body size and shape, overall mobility, and morphology of body hairs (Wheeler 1918;Wheeler and Wheeler 1953. In particular the size, shape, distribution and density (= pilosity) of larval hairs can differ between species, as well as between developmental stages, sexes and castes within single species Vinson 1978, 1979a;Solis et al 2010bSolis et al , a, 2011Solis et al , 2012bFox et al 2011;Wang et al 2017). In Monomorium and Solenopsis ants, differences in the pilosity of worker-and queen-destined larvae may help workers recognize the two castes (Edwards 1991;Fox et al 2011).…”

In Myrmica ants, the increasing pilosity of larvae over the course of development has been suggested to be crucial for recognition, together with brood chemistry and tactile cues such as turgidity, size, shape, and cuticle surface properties (Brian 1975a).…”

Brood recognition and discrimination in ants

In social insect colonies, individuals need to communicate to coordinate cooperative tasks and protect the colony and its resources against intruders. To maintain colony integrity, it can be particularly important to recognize nestmates and discriminate against non-nestmate conspecifics and heterospecific predators and parasites. As typical intruders are either con-or heterospecific adults, the mechanisms underlying recognition and discrimination processes in interactions among adults have been well described. Ant brood (eggs, larvae, and pupae) can also play a key role in social interactions, and brood is of special importance when it comes to the priorities of worker ants. However, whether ants can, or even need to, recognize brood of different origins, is not always clear. In this review, we integrate the results of 100 years of study on brood recognition and discrimination in ants into a general framework. We begin with an overview of the proximate mechanisms involved in brood recognition and discrimination. We then discuss why brood recognition and discrimination should evolve and review the evidence for brood recognition on three organizational levels: within nests, between conspecifics and between species. We conclude by examining the constraints acting on accurate recognition and/or discrimination. With this review, we hope to inspire future research on the fascinating life of ant brood.

“…In 2005, we initiated a project to study material deposited in collections worldwide and sampled all major islands in the archipelago, which resulted in many new ant records (Fig. 1 ) (among others: Longino 2003 ; Pacheco et al 2007 ; Herrera and Longino 2008 ; Herrera and Causton 2010 ; Lattke 2011 ; Herrera et al 2013 , 2014 ). Here, we list all known species records (past and present) from the Galápagos Islands and provide an illustrated identification key for the established 47 taxa known to date, we do not include dubious records in the key.…”

The Galápagos ant fauna has long been understudied, with the last taxonomic summary being published almost a century ago. Here, a comprehensive and updated overview of the known ant species of the Galápagos Islands is provided with updated species distributions. The list is based on an extensive review of literature, the identification of more than 382,000 specimens deposited in different entomological collections, and recent expeditions to the islands. The ant fauna is composed of five subfamilies (Dolichoderinae, Dorylinae, Formicinae, Myrmicinae, and Ponerinae), 22 genera, 50 species, and 25 subspecies, although three species (Crematogaster crinosa Mayr, 1862, Camponotus senex (Smith, 1858), and Solenopsis saevissima (Smith, 1855)) are considered dubious records. Finally, an illustrated identification key of the species found in the archipelago is presented.

The ontogeny of an organism provides fundamental insights into its life history and evolutionary background. Among insects, especially ants, relatively few observations have been formalized about the morphology of immature stages. Using light and scanning electron microscopy, this study presents the first description of the different larval instars of Aphaenogaster cristata (Forel, 1902) and Aphaenogaster pachei (Forel, 1906), species endemic to the Himalayas that predominate in areas where cold temperature stress and disturbances limit the presence of other ants. The existence of four larval instars was estimated based on the frequency distribution of their measured maximum head widths. We observed discrete alterations in the body constitution and parts among the different instars, suggesting they must follow similar habits until pupation. The two species, however, present noticeable particularities in their mandibles and hair types, suggesting intrinsic life adaptations. Observed traits complementary with previous descriptions with larvae of the genus and related taxa are suggestive of considerable evolutionary distance from Messor, considered the sister clade, which merits further taxonomic investigation in future studies.
