Hidden invaders: intraspecific cryptic invasion and hybridization of Dolichoderus thoracicus (Hymenoptera: Formicidae) in Taiwan.

Biological invasions pose substantial threats to global biodiversity, agriculture, and ecological stability. Among these, intraspecific cryptic invasions, characterized by the spread of nonnative genotypes within a species, present unique challenges for detection and management. Despite the well-documented influence of invasive ants on ecosystems, instances of intraspecific cryptic ant invasions have rarely been documented.

Putative source and niche shift pattern of a new alien ant species () in Taiwan.

Alien species may pose substantial impacts on biodiversity around the globe through international trade and travel. A niche shift hypothesis was proposed to explain the adaptive change of alien or invasive species in new habitats. However, whether niche shifts occur in alien species likely depends on both characteristics inherent to the species itself and its original distribution.

A new species of from Taiwan (Hymenoptera, Formicidae, Amblyoponinae).

is the most speciose ant genus in the subfamily Amblyoponinae. In the present paper, the worker caste of a new species is described, , which was collected from a soil sample in a subtropical evergreen broad-leaved forest in Taiwan. An identification key to the females of species with 11 antennomeres occurring in Asia is also provided.
