Abstract Species of the genus Acropyga are rarely encountered subterranean ants that rely on mealybugs or aphids to provide their nutritional needs. Female Acropyga (Formicinae) alates of pantropical and Mediterranean species carry mealybugs with their mandibles while swarming and probably inoculate their new nests with these mealybugs. The natural history of Acropyga and other mealybug-tending ant species, a summary of the various reports of Acropyga females toting mealybugs, and a new record… 

A new ortheziid (Hemiptera: Coccoidea) from Australia associated with Acropyga myops Forel (Hymenoptera: Formicidae) and a key to Australian Ortheziidae

This study represents the first non-mealybug association between a scale insect and Acropyga ants, and the new ortheziid genus has a number of unusual morphological attributes that may represent adaptations to its relationship with ants.

Trophobiosis between a new species of Williamsrhizoecus (Hemiptera: Coccomorpha: Rhizoecidae) and Acropyga silvestrii (Hymenoptera: Formicidae) in Tanzania.

A new myrmecophilous species of root mealybug, Williamsrhizoecus udzungwensis sp. n., is described from individuals found living within a nest of Acropyga silvestrii in the Udzungwa Mountains of

Systematics of the mealybug tribe Xenococcini (Hemiptera: Coccoidea: Pseudococcidae), with a discussion of trophobiotic associations with Acropyga Roger ants

The systematics and biology of the xenococcine mealybugs is discussed in the context of obligate ant symbiosis and the phylogeny of this tribe is derived for the first time using morphological data from adult females through Bayesian inference and maximum parsimony methods.

Ants and Subterranean Sternorrhyncha in a Native Grassland in East-Central Alberta, Canada

There were no significant correlations between presence of subterranean sternorrhynchans and percent cover of different plant types, soil moisture content, slope, aspect, or visible entrances to ant nests.

Phylogenetic position of the ant genus Acropyga Roger (Hymenoptera: Formicidae) and the evolution of trophophoresy.

Evidence is presented in favor of Acropyga being monophyletic, hence trophophoresy has evolved only once within the Formicinae and twice within the ants overall, and the results indicate that the Lasiini and Plagiolepidini are not monophylets and are in need of reexamination.

A synopsis of the subterranean mealybug genus Neochavesia Williams and Granara de Willink (Hemiptera: Pseudococcidae: Rhizoecinae)

The neotropical mealybug genus Neochavesia, associated with the ant genus Acropyga Roger, is discussed and placed in the tribe Xenococcini on the bases that it lacks dorsal ostioles, the distal end

A new genus and species of Rhizoecidae (Hemiptera, Sternorryncha, Coccomorpha) associated with Acropyga yaeyamensis (Hymenoptera, Formicidae, Formicinae)

This new species was found in the nest of a rare Japanese ant, Acropyga yaeyamensis Terayama & Hashimoto, 1996, in Ishigaki Is., Japan, and resembles Capitisetella migrans and Pseudorhizoecus proximus Green, 1933, but differs from those two species in having small multilocular pores, large 3-5 locular pores on the medial area of ventral abdomen, and two different-sized body setae.

A mutualism without honeydew: what benefits for Melissotarsus emeryi ants and armored scale insects (Diaspididae)?

This study studied three colonies of Melissotarsus emeryi ants from two localities in Mozambique, documenting the occurrence of rare individuals with shields inside ant galleries, indicating that their glands continue to secrete wax and proteins as building material.

Karıncalar (Hymenoptera: Formicidae) ve Coccoidea (Hemiptera: Sternoryncha) Türlerinin İlişkileri

The mutual relations between ant and scale insects in poly-cultural environments should be considered more seriously than in mono- cultural environments during pest management.

Diverse New Scale Insects (Hemiptera: Coccoidea) in Amber from the Cretaceous and Eocene with a Phylogenetic Framework for Fossil Coccoidea

16 new species, 11 new genera, and three new families are added to the coccoid fossil record based on a study of male coccoids in Lebanese amber, Burmese amber, Cambay amber from western India, and Baltic amber.



Ants of the genus Acropyga Roger, with description of a new species.

Within recent years Acropyga, which seemed to be a rather insignificant genus of tropical Formicine ants, has been acquiring a reputation as a serious though indirect pest in certain South American

Systematics of Fossil Aphids From Canadian Amber (Homoptera: Aphididae)

  • W. Richards

  • 1966
Five Cretaceous fossil aphids from Canadian amber are described and the main features of the evolution of the aphid wing are discussed as an aid in placing the fossils with respect to current concepts of aphid classification.

New trophobiotic symbioses of ants with South East Asian bugs.

A trophobiotic relationship between two species of phloem-feeding plataspid bugs and an ant, Meranoplus mucronatus, was discovered on tree trunks in Malaysia, and the coreids on bamboo were determined as Cloresmus spp.

New and rediscovered primitive ants (Hymenoptera: Formicidae) in Cretaceous amber from New Jersey, and their phylogenetic relationships

Discovery of new and exclusively primitive ants in upper Cretaceous ambers indicates an origin of the ants probably in the lowermost Cret Jurassic, but no older, contrary to a recent molecular hypothesis.

Mutualism between Thisbe irenea butterflies and ants, and the role of ant ecology in the evolution of larval‐ant associations

Observations and literature records indicate that ant taxa which tend butterfly larvae are the same taxa that tend extrafloral nectaries and Homoptera, and hence, ant-larval mutualisms.

Ant–plant–homopteran mutualism: how the third partner affects the interaction between a plant-specialist ant and its myrmecophyte host

The role of the homopteran partner in the protection mutualism between the myrmecophyte Leonardoxa africana T3, the ant Aphomomyrmex afer, and sap–sucking homopterans tended by ants in the tree's swollen hollow twigs is explored and hypotheses to explain how the type of homoptera affects functioning of this symbiosis are presented.

The Earliest Known Fossil Ant(First Southern Hemisphere Mesozoic Record)(Hymenoptera: Formicidae: Myrmeciinae)

Four other Cretaceous genera, described in the same publication (Cretopone, Petropone, Archaeopone and Dolichomyrma)were found in southern Kazakstan in considerably older beds (Turonian) and originally considered to belong to the extant subfamily Poiaerinae.

The earliest known ants: an analysis of the Cretaceous species and an inference concerning their social organization

The known Cretaceous formicoids are better interpreted from morphological evidence as forming a single subfamily, the Sphecomyrminae, and even a single genus, SpheComyrma, rather than multiple families and genera, and share some key traits with nonsocial aculeate wasps.
