Extinct haidomyrmecine" hell ants" are among the earliest ants known [1, 2]. These eusocial
Cretaceous taxa diverged from extant lineages prior to the most recent common ancestor of …

Ants show remarkable ecological and evolutionary success due to their social life history
and division of labour among colony members. In some lineages, the worker force became …

The division of labor into sterile and reproductive castes in social insects is often reflected in
marked morphological differences, which might have played an important role in the …

This paper provides a taxonomic revision and a review of the biology for the 10 species of
North American seed-harvester ants in the genus Veromessor. Two new synonomies are …

One of the largest species in its genus, Odontomachus davidsoni Hoenle, Lattke & Donoso,
sp. nov. is described from workers and queens collected at lowland forests in the Chocó …

Phenotypic traits are often integrated into evolutionary modules: sets of organismal parts that
evolve together. In social insect colonies, the concepts of integration and modularity apply to …

Advances in technology are rapidly changing the way people transmit, view, and interact
with information. These advances offer new opportunities for researchers to share scientific …

Cryptic species are morphologically very similar to each other. To what extent stasis or
convergence causes crypsis and whether ecology influences the evolution of crypsis has …

In the hyperdiverse ant genus Pheidole Westwood, 1839, the worker caste evolved into two
morphologically distinct subcastes: minor workers and soldiers. The evolution of soldiers …

Island biodiversity has long fascinated biologists as it typically presents tractable systems for
unpicking the eco‐evolutionary processes driving community assembly. In general, two …
