Over five hundred non-native ant species have spread worldwide, including many that have severe effects on biodiversity, are serious economic pests, or threaten human health and agriculture. The number of species in the Mediterranean is steadily increasing, with Italy being a prominent example. We provide risk screenings for non-native ant species...

The existence of different male morphologies within a single species is associated with alternative mating tactics across different animal groups, offering textbook examples of evolutionary biology. The European stag beetle Lucanus cervus is a flagship species which has long fascinated naturalists for its charismatic appearance and behavior, with m...

Gall formation in plants often imposes physiological costs from which secondary colonizers may benefit. Oak galls induced by Andricus wasps are later colonized by arboreal-nesting ants that may provide a service to the plant in an-thropogenic environments. Trees in these environments frequently lack appropriate structures or deadwood to host arbore...

The Mediterranean, a global hotspot for rare ant species, hosts a significant representation of the global diversity of the mainly Holarctic ant genus Temnothorax. However, several groups still require significant taxonomic efforts. The taxonomy of the T. luteus complex species was revised in 2014 when morphometrics allowed distinguishing two valid...

Ants are ubiquitous and eusocial insects that exhibit frequent physical contact among colony members, thereby increasing their susceptibility to diseases. Some species are often found in beehives and in their surroundings, where they exploit the food resources of honey bees. This intricate relationship may facilitate the interspecific transmission...

Temnothorax unifasciatus (Latreille, 1798) is a widely distributed pan-European species from the Iberian Peninsula to the Caucasus. This taxon's relatively high morphological variability prompts the taxonomists of earlier times and today to mention the morphologically different elements at specific or subspecific ranks. This paper aims to understan...

The number of known alien ant species throughout Europe has been steadily increasing during the last few decades and Italy has been no exception, with four new taxa reported in the last five years. Here, we document new data on the Asian needle ant Brachyponera chinensis (Emery, 1895), an invasive alien species whose first establishment in Europe w...

Until recently, Hypoponera ergatandria was commonly misidentified as H. punctatissima, both of which are widespread tramp ant species. Today, H. ergatandria has been recorded in eleven European countries, while most existing H. punctatissima records are doubtful. Its geographic origins, like in the case of H. punctatissima, remain unclear. Here, we...

We report for the first time the occurrence of the alien ant Cardiocondyla obscurior Wheeler, 1929 on the Greek island of Crete. Cardiocondyla obscurior is one of many congeneric taxa with worldwide success as tramp species, having attained a cosmopolitan distribution while having Indomalayan origins. It was first detected in Europe in 1999, and si...

Due to particular vulnerabilities and environmental constraints, Alpine faunas are exposed to significant threats from climate change. However, baseline diversity and distribution data to monitor the trends of key arthropod groups are often scarce. Ants are highly diversified and key ecological actors across terrestrial ecosystems, including mounta...

Mutualistic associations between ants and honeydew-producing hemipterans have a great ecological and evolutionary significance across terrestrial habitats but can also cause pest outbreaks in agroecosystems. At the same time, ants are often effective predators of several agricultural pests, can improve soil quality, and can control some plant patho...

The ant genus Vollenhovia Mayr, 1865 (Myrmicinae, Crematogastrini) mostly occurs in the Australasian and Oriental regions. We revised its diversity in India and Sri Lanka based on qualitative and quantitative morphology, recognizing eleven taxa, including a new species which is described herewith: V. escherichi Forel, 1911, V. gastropunctata Bharti...

Mutualism between ants and honeydew-producing hemipterans is a highly successful evolutionary innovation that attains the status of ecological keystone across many terrestrial ecosystems, involving a multitude of actors through direct or cascading effects. In these relationships, ants often protect their hemipteran partners against their arthropod...

Three new species in the Tetramorium tortuosum group, T. alii, T. binghami and T. hitagarciai, are described and illustrated from the Western Ghats, India. In addition, information on the remaining six know species in this group — T. belgaense Forel, 1902, T. keralense Sheela & Narendran, 1998, T. pilosum Emery, 1893, T. tortuosum Roger, 1863, T. u...

The brown marmorated stink bug Halyomorpha halys is an Asian species that has become a major agricultural pest in North America and Europe. Ants from the genus Crematogaster are predators of H. halys nymphs in Asia, as well as in the Mediterranean, where known native predators are still few. At the same time, ants usually do not harm H. halys eggs,...

The presence of the spider genus Thyreosthenius Simon, 1884 (Linyphiidae) is for the first time confirmed in the Iberian Peninsula with an observation of the myrmecophile species T. biovatus (O. Pickard Cambridge, 1875). Four adult females and two sub-adult male specimens were collected inside mound nests belonging to the red wood ant species Formi...

Ants (Hymenoptera: Formicidae) play a relevant ecological role across terrestrial ecosystems. Recent studies suggest that the presence of ants in crops could lead to a decrease in the populations of insect pests, but how these actions can vary along the different trophic levels is not well known. The southern green stink bug, Nezara viridula (L.) (...

The European stag beetle, Lucanus cervus , is the largest saproxylic beetle and a flagship species whose populations should be monitored according to the EU Habitats Directive. Different studies have addressed its abundance and phenology, its relationship with deadwood, or the allometry of males related to different reproductive strategies. While m...

Diversity patterns can show congruence across taxonomic groups. Consistent diversity patterns allow the identification of indicator surrogates potentially representative of unobserved taxa or the broader biodiversity patterns. However, the effective use of biodiversity surrogates depends on underlying mechanisms driving the strength of the relation...

Many ants and hemipterans are bound by a mutualistic relationship (trophobiosis) which represents an ecological keystone: ants receive food (honeydew) providing different kinds of protection. Partner protection against arthropod natural enemies is considered to be frequent and to interfere with biological control strategies of hemipteran pests. We...

The ant genus Aphaenogaster Mayr, 1853 is especially diverse in the West-Palearctic region, where its taxonomy is still problematic for several groups. Among other issues, there is a redundancy of valid taxa compared to the number of species whose validity is currently sustained by any evidence. Names that do not represent taxa with clearly defined...

1. Vineyards are economically valuable agroecosystems that have spread to all continents. As such, sustainable management of their pests is an important goal. Mealybugs are serious pests of vines with Planococcus ficus (VMB) being the most problematic worldwide. Mealybugs are attended by different ant species, whose trophobiotic relationship is oft...

There are only two Aphaenogaster species from the subterranea group in the western Mediterranean: A. ichnusa Santschi, 1925, from southwestern Europe, and A. subterranea (Latreille, 1798), also occurring in central and eastern Europe. Historically, the two species have been widely misunderstood: A. ichnusa was long considered a Sardinian endemic su...

Lasius maltaeus Seifert, 2020 was recently described as a Maltese endemic ant based on quantitative morphology, after decades of uncertainties over the identity of the local population, which has a phenotype resembling L. emarginatus (Olivier, 1791). At the same time, Sicilian L. emarginatus populations were discovered to diverge in their mitochond...

Among ants, plesiobiotic associations are defined as occasional or regular nesting of heterospecific colonies nearby and without any biological interdependence. Habitats with a scarcity of available nesting microhabitats and ecological dissimilarity between the involved species are supposed to favor the frequency of plesiobiosis. In the last review...

Abstract Aim Biogeographical regionalization is scant for most insect groups due to shortfalls in distribution and phylogenetic information, namely the Wallacean and Darwinian shortfalls respectively. Here, we focused on the European ants and compared new techniques to classical analyses based on regional lists and taxonomic methods. We asked the...

The predatory ability of ants (Hymenoptera, Formicidae) against insect pests can offer an important service to agricultural activities and may sometimes be directly exploited in biological control strategies. The codling moth Cydia pomonella (Lepidoptera, Tortricidae) is a major agricultural pest of fruit orchards, whose biological control is compl...

The West-Palearctic region is a diversity hotspot for the ant genus Aphaenogaster. Species in this region are characterized by high morphological variation, which has led to their subdivision into different infrageneric groups. The very first classification in three subgenera, dated 1915, was gradually replaced by eight species-groups. To probe the...

We investigated the diversity of ant assemblages visiting pear trees in Italy by comparing two orchards from a northern region with continental climate (Emilia-Romagna) and a southern region with Mediterranean climate (Sicily). Overall we identified 20 ant species belonging to 10 genera and 3 subfamilies. The ant communities of the two sites look s...

Galls are neoformed structures induced on the tissues of a host plant by different organisms, mostly insects. Apart from the inducers, galls can also provide shelter to several different arthropods, referred to as secondary occupants. In certain types of galls, ants are among the prevalent secondary colonizers. This study focuses on oak galls induc...

Land-use intensification exacerbates landscape fragmentation, increasing the negative effects on biodiversity. In this context, the biodiversity value of Trees Outside Forests (TOF; scattered trees, tree lines and small woodlots) is often overlooked by landscape planning and conservation programs, which typically focus on protecting larger and more...

Ants belonging to the Formica rufa species group, counting 10 representatives in Europe, are often referred to as red wood ants (RWAs). These dominant, mound building species are known to host in their nests an extremely diverse fauna of associated myr- mecophilic arthropods, among which are the two W-Palaearctic spider species Mastigusa arietina (...

Soil-dropping is a rarely observed interference behavior so far only documented for six phylogenetically very diverse ant species. Usually, it is employed against rival ant colonies, and may aim to plug their nest entrances to stop their foraging activities. Here, we provide the first testimony of the use of soil dropping by Tetramorium ants agains...

Due to their ubiquity and their nature as generalist predators, ants have long been used as biological control agents in forest and agricultural systems. Several exotic ambrosia beetles (Coleoptera: Curculionidae: Scolytinae, Platypodinae) are considered emerging widespread pests of various trees and shrubs growing in forests, nurseries, orchards,...

Temnothorax (Myrmicinae, Crematogastrini) is one of the most diverse Holarctic ant genera, and new taxonomic advancements are still frequent worldwide. The Mediterranean region, a global biodiversity hotspot characterized by a complex geographic history, is home to a substantial portion of its described diversity. Sicily is the region’s largest isl...

I present the updated version of the ‘Checklist of the Italian Fauna’ for what concerns ants (Insecta: Hymenoptera: Formicidae), which is part of the broader effort to produce an updated comprehensive checklist of the Italian fauna about 25 years after the first edition. The present list is the fourth Italian checklist of ants to be published since...

The West-Palaearctic Colobopsis ant populations have long been considered a single species (Colobopsis truncata). We studied the diversity of this species by employing a multidisciplinary approach and combining data from our surveys, museum and private collections, and citizen science platforms. As a result, we have revealed the existence of a seco...

Aim Biogeographic regionalization has fascinated biogeographers and ecologists for centuries and is endued with new vitality by evolutionary perspectives. However, progress is scant for most insect groups due to shortfalls in distribution and phylogenetic information, namely Wallacean and Darwinian shortfalls respectively. Here, we used the western...

Among odonates that exhibit endophytic oviposition, a few, mostly damselflies, are known to be able to perform underwater oviposition. Among them, just a few species do so very frequently. Here I report the first observation of underwater oviposition for the damselfly Ischnura genei, which becomes the eighth species of its genus known to adopt this...

1. We studied the interactions involving oak acorns and associated arthropods focus-ing on the role of the introduced Quercus rubra in Italy. 2. We conducted our study in areas where native oaks coexist with Q. rubra. We carried out a survey on the arthropods inhabiting fallen acorns and a colonisation experiment. Furthermore, we conducted laborat...

Formica clara is an ant species that was historically confused with other congeneric species such as F. rufibarbis until recent taxonomic developments. Due to such misunderstanding, while F. clara is known to occur across a very large Eurasian range, its actual distribution in the Mediterranean is often scarcely known. The distribution of F. clara...
