Summary1.Eurhopalothrix heliscata n. sp. is an Asiatic representative of the little known ant tribe Basicerotini and the first member of the group to be studied intensively. We report evidence that it preys on a variety of termites, but also takes at least some other kinds of insects. Overall, the social behavior is simple relative to that of many other myrmicine ants.2.Prey are hunted and retrieved singly. But foraging workers are also able to recruit nestmates to the vicinity of groups of… 

Ecology and behavior of the neotropical cryptobiotic antBasiceros manni (Hymenoptera: Formicidae: Basicerotini)

Basiceros manni has a behavioral repertory comparable in complexity but not in detail to that ofEurhopalothrix heliscata, the only other basicerotine species studied to date.

Behavior of the group-predatory antProatta butteli (Hymenoptera: Formicidae): An old world relative of the attine ants

Morphological evidence indicates the Southeast Asian genusProatta is phylogenetically close to the Attini, with polygynous colonies, and the worker repertoire, temporal division of labor, and emigration behavior are discussed.

First Record of The Ant Rhopalothrix weberi (Hymenoptera: Formicidae: Myrmicinae) for Mexico

The first record of Rho palothrix weberi Brown and Kempf for Mexico is reported, which is similar to Eurhopalo thrix, but with thinner, more elongate, triangular jaws.

Dominance orders in the ponerine ant Pachycondyla apicalis (Hymenoptera, Formicidae)

These results indicate that workers of P. apicalis lay eggs even in the presence of the queen, and report for the first time a natural (nonmanipulated) change in the social status of individuals within an ant dominance order.

Marking of Nest Entrances and Vicinity in Two Related Tetramorium Ant Species (Hymenoptera: Formicidae)

Workers of the related ants Tetramorium impurum and T. caespitum mark the vicinity of their nest entrances in a species-specific manner, as seen by similarities between the behavior of nestmates and

Soil-binding pilosity and camouflage in ants of the tribes Basicerotini and Stegomyrmecini (Hymenoptera, Formicidae)

Workers of the tropical ant tribes Basicerotini and Stegomyrmecini possess two dominant forms of setae: longer “brush” hairs with splintered distal ends, and shorter “holding’ hairs that vary among species from plumose to blade-shaped or filiform.

A Phylogenetic Analysis of the Dirt Ants, Basiceros (Formicidae: Myrmicinae): Inferring Life Histories Through Morphological Convergence

Focusing on the female castes of Basiceros, an ancestral state reconstruction is presented for mandibles and labrum morphology, and results suggest that the labrum and clypeomandibular morphologies are highly labile, although phylogenetically important characters in the genus.

Use of termites, Reticulitermes virginicus, as a springboard in the invasive success of a predatory ant, Pachycondyla (=Brachyponera) chinensis

The behavior of P. chinensis in the presence of termites increases their competitive abilities in natural areas where they have been introduced, and it is suggested that subterranean termites are critical for P.chinensis success in new habitats.

Third Argentine record of Eurhopalotrhix bruchi (Santschi, 1922) (Hymenoptera, Formicidae), description of an interomorphic queen and the colony, and notes on biology and ecology

The scarcity of pre-imaginal stages suggests that fission of the colony led to the nest’s foundation and the queens are characterized as wingless, without wing sclerites, and workerlike.

Polydomy in the ant Ectatomma opaciventre

The analysis of the cuticular hydrocarbons apparently con-firmed the hypothesis that this species is polydomous, since the chemical profiles of all studied colonies with nests at different sites were very similar to the chemical signature of the single found queen and were also different from those of colonies used as control.



Feeding Behavior in the Ant Rhopalothrix biroi Szabó

Through recent w.ork on the biology of the tribe Dacetini, it is now known that the members of this large, cosmopolitan group are generally predators which feed primarily on collembolans and

Colony founding in Myrmecocystus mimicus wheeler (Hymenoptera: Formicidae) and the evolution of foundress associations

It is concluded that competition among founding nests favors foundress associations and that inter-colony raiding is a natural consequence of aggregated pleometrotic founding nests.

The Evolution of the Dacetine Ants

A preliminary synthesis of evolutionary studies of certain morphological and ethological characters in the ant tribe Dacetini is given, inferring the shift from epigaeic-subarboreal to cryptic-terrestrial foraging and a local reversal in the overall dacetine trend to specialization.

Notes on the Indo-Australian Basicerotine ants (Hymenoptera : Formicidae)

Rhopalothrix orbis is the first species of its genus recorded from Australia and a key to the Indo-Australian fauna of tribe Basicerotini.

Trail Communication in the Dacetine Ant Orectognathus Versicolor (Hymenoptera: Formicidae)

Although division of labor within two dacetine species has been studied at length (Wilson 1962; Carlin 1982), very little has hitherto been reported on social communication in the Dacetini, a

The relation between caste ratios and division of labor in the ant genus Pheidole (Hymenoptera: Formicidae)

A distinction is made between programmed “elasticity” in the repertory of individual workers and castes and the “resiliency” of the colony as a whole, which depends upon the pattern of caste-specific elasticity.

Karyotype evolution in Australian ants

The data provide little support for the ancestral chromosome number in ants having been high with subsequent reduction, but suggest that the ancestral number was either very low with subsequent increase or coincident with the present mode (“modal hypothesis”).


Two species are described as new: E. hoplites (Papua New Guinea) and E. insidiatrix (Vanua Levu, Fiji Islands). Both are illustrated with scanning electron micrographs, as are E. szentivanyi Taylor
