Abstract: We present an updated list of introduced ants to continental Ecuador, and compile records of occurrence, as well as map the distribution of 15 exotic species. We analyzed specimens in entomological collections and data from AntWeb, GBIF and iNaturalist. Among these, we add two new records for the country: Cardiocondyla mauritanica Forel, 1980 and Pheidole megacephala (Fabricius, 1793). The former is also the first record for South America, while the finding of the latter shows how little we know about introduced tramp ants. In addition, we add site records for nine species: Cardiocondyla emeryi Forel, 1881, Cardiocondyla minutior Forel, 1899, Cardiocon­dyla wroughtonii (Forel, 1890), Linepithema humile (Mayr, 1868), Monomorium floricola (Jerdon, 1851), Monomo­rium pharaonis (Linnaeus, 1758), Paratrechina longicornis (Latreille, 1802), Tapinoma melanocephalum (Fabricius, 1793), and Tetramorium bicarinatum (Nylander, 1846). Based on our previous fieldwork observations, it appears that our understanding of exotic species richness is still in its early stages.

Occurrence of Pheidole tijucana Borgmeier, 1927 (Hymenoptera, Formicidae) in the state of São Paulo, Brazil https://checklist.pensoft.net/article/100991/ Check List 19(2): 169-175

DOI: 10.15560/19.2.169

Authors: Débora Cristina de Oliveira Gonçalves, Lívia Pires do Prado, Fabrício Severo Magalhães, Marlina Ribeiro Abonizio-Santos, Maria Santina de Castro Morini

Abstract: Pheidole Westwood, 1839 is a hyperdiverse ant genus that is widely distributed in a variety of terrestrial ecosystems, especially in the tropics. The identification of Pheidole species is challenging, thus contributing to the description of several questionable morphospecies in the literature and making the geographic distribution of most species uncertain. In this work, we present the first records of Pheidole tijucana Borgmeier, 1927 from the state of São Paulo, Brazil. The specimens were recorded at Parque Ibirapuera Conservação, an urban green area located in the southern part of the city of São Paulo. The sampling was performed in 2015, 2016, and 2017 using pitfall traps. In total, 224 specimens (one major worker and 223 minor workers) of P. tijucana were recorded. Our new data help fill a distribution gap and highlights the importance of reporting species that are a challenge to identify.

Survey of ants (Hymenoptera, Formicidae) in the city of Providence (Rhode Island, United States) and a new northern-most record for Brachyponera chinensis (Emery, 1895) https://checklist.pensoft.net/article/90866/ Check List 18(6): 1347-1368

DOI: 10.15560/18.6.1347

Authors: James S. Waters, Nicole W. Keough, Joseph Burt, Jonathan D. Eckel, Trey Hutchinson, Jonathan Ewanchuk, Matthew Rock, Jeffrey A. Markert, Heather J. Axen, David Gregg

Abstract: We surveyed ants in Providence, Rhode Island, from 2015 to 2019. Methods including repeated pitfall trap sampling and manual searching were used to collect ants at Providence College and a rapid biological assess-ment was conducted at Roger Williams Park. A total of 36 species were identified based on morphology, including the first observations of a colony of Needle Ants (Brachyponera chinensis Emery, 1895) in New England. Twenty-six species identified were new county records and seven species were new state records, representing a substantial update to the list of known ant species in Rhode Island, currently totaling 41 species in Providence and 69 spe-cies from six subfamilies across the state. These results are comparable with similarly scaled surveys conducted at parks and cities across the world, and they also offer a reminder that while urbanization can be associated with reductions in habitat availability for some fauna, cities can be accessible and ecologically important locations for exploring myrmecological biodiversity.

New distribution record of Bicolored Trailing Ant, Monomorium floricola (Jerdon, 1851) (Hymenoptera, Formicidae) from Ecuador, with information on cohabitation with the social spider Anelosimus eximius (Keyserling, 1884) https://checklist.pensoft.net/article/81360/ Check List 18(2): 399-404

DOI: 10.15560/18.2.399

Authors: Pablo Sebastián Padrón, Lucía Vanessa Ortiz, Pamela Estefanía Andrade, José Manuel Falcón, Anja Junghanns

Abstract: Invasive ant species are a serious threat to native fauna, especially in highly diverse tropical countries. Therefore, new distribution reports and information on the interactions with other species are essential to understand the potential effects of invasive ants on biodiversity. Here we report for the first time the presence of colonies of Monomorium floricola (Jerdon, 1851) in the nest of the Neotropical social spider Anelosimus eximius (Keyserling, 1884) in the southern part of the Ecuadorian Amazon. Our report extends the known distributional range of M. floricola to the southern Ecuador.

First record of the rarely collected ant Protanilla gengma Xu, 2012 (Hymenoptera, Formicidae, Leptanillinae) from the Indian subcontinent https://checklist.pensoft.net/article/57103/ Check List 16(6): 1621-1625

DOI: 10.15560/16.6.1621

Authors: Punnath Aswaj, Karunakaran Anoop, Dharma Rajan Priyadarsanan

Abstract: Protanilla gengma Xu, 2012 is recorded for the first time from the Indian subcontinent. This rarely collected ant species was previously known only from Yunnan Province, China. Two workers of P. gengma were collected from the Lengteng Wildlife Sanctuary, Mizoram, Northeast India, using the Winkler extraction method. This find also represents the first record of the subfamily Leptanillinae from Northeast India and the third species of the genus Protanilla Taylor, 1990 from India. We present an updated distribution map for the genus and comment on morphological variation of the worker caste of P. gengma.

A checklist of the non-leaf-cutting fungus-growing ants (Hymenoptera, Formicidae) from Colombia, with new biogeographic records https://checklist.pensoft.net/article/56929/ Check List 16(5): 1205-1227

DOI: 10.15560/16.5.1205

Authors: Daniela Mera-Rodríguez, Francisco Serna, Jeffrey Sosa-Calvo, John Lattke, Christian Rabeling

Abstract: The non-leaf-cutting fungus-growing ants deposited in two entomological collections in Colombia were curated and identified to assess their diversity in the country. We examined 680 specimens, identifying 41 species belonging to seven genera, bringing the total of fungus-growing ant species known from Colombia to 85. The following species are new records for Colombia: Apterostigma angustum Lattke, 1997, Mycetomoellerius jamaicensis (André, 1893), Paratrachymyrmex diversus (Mann, 1916), and Paratrachymyrmex phaleratus (Wheeler, 1925).

Ants in the diet of Collared Anteater, Tamandua tetradactyla (Linnaeus, 1758) (Pilosa, Myrmecophagidae), in the state of Rio de Janeiro, Brazil https://checklist.pensoft.net/article/39559/ Check List 15(6): 1145-1151

DOI: 10.15560/15.6.1145

Authors: Márcio Morais Silva, Carlos Eduardo Lustosa Esbérard, Antônio José Mayhé-Nunes, Cecília Bueno

Abstract: The Collared Anteater, Tamandua tetradactyla (Linnaeus, 1758), is a small mammal predator of ants. There are few studies describing which species are in fact consumed by them. This study was aimed to investigate the diversity and abundance of local species of ants preyed by the T. tetradactyla. Eight samples of stomach contents collected in the period from 2009 to 2014 were analyzed and identified at the lowest possible taxonomic level. We found 5,906 ants distributed in 16 species. The most abundant samples were number 2 and 4 with almost 2,000 individuals and the highest richness and abundance was Myrmicinae subfamily with eight species and 3,721 individuals. The ant richness found in this research demonstrates that the anteaters are generalists and opportunistic about their diet, not having a preference for a particular species, but rather for those insects that are available in their habitat.

Third Argentine record of Eurhopalotrhix bruchi (Santschi, 1922) (Hymenoptera, Formicidae), description of an interomorphic queen and the colony, and notes on biology and ecology https://checklist.pensoft.net/article/23159/ Check List 14(2): 329-334

DOI: 10.15560/14.2.329

Authors: Juan M. Arcusa, Armando C. Cicchino

Abstract: Eurhopalothrix bruchi is the only species of the genus present in Argentina. We present only the third record of this species from Argentina and describe for the first time the female and characteristics of the colony. The nest collected had 48 workers, 6 queens, and 4 pupae. The queens are characterized as wingless, without wing sclerites, and worker-like. The scarcity of pre-imaginal stages suggests that fission of the colony led to the nest’s foundation.

New locality record of Discothyrea neotropica (Bruch, 1919) (Hymenoptera, Formicidae) for Argentina and remarks on its distribution https://checklist.pensoft.net/article/21507/ Check List 13(5): 635-638

DOI: 10.15560/13.5.635

Authors: Juan M. Arcusa, Armando C. Cicchino

Abstract: We collected a queen specimen of Discothyrea neotropica Bruch, 1919 in a pitfall trap in Paititi Natural Reserve, southeastern Buenos Aires province, Argentina. The new record represents the southernmost occurrence for this species and extends its habitat preferences to a humid temperate climate. Our record of D. neotropica is the first in Argentina since 1949.
