Temnothorax caguatan

Snelling, Borowiec & Prebus, 2014

Temnothorax caguatan is a of small described in 2014 from California, USA. It belongs to a of cavity-nesting ants known for nesting in pre-existing cavities such as hollow acorns, twigs, and rock crevices. The species was one of ten new Temnothorax species described from California in a single study, effectively doubling the known of this genus in the state. Like other members of Temnothorax, it is likely a scavenger with colonies of moderate size.

Identification

Temnothorax caguatan can be distinguished from other Temnothorax using the illustrated provided by Snelling et al. (2014). As with most Temnothorax, identification relies on subtle morphological characters including propodeal shape, node proportions, and antennal length relative to width. The species is small-bodied, typical for the , with likely measuring 2–3 mm in length. Precise diagnostic characters require examination of and reference to the original description.

Habitat

Temnothorax are generally associated with forested and woodland where suitable nesting cavities occur. Based on the California distribution of related species, T. caguatan likely inhabits oak woodland, chaparral, or mixed coniferous forest where hollow acorns, dead twigs, or rock crevices provide nest sites.

Distribution

Known from California, USA. The precise locality and full range within California are not specified in available sources, but the was described from material collected in the state as part of a comprehensive revision of California Temnothorax.

Behavior

Temnothorax typically exhibit monogynous colony structure with moderate . They are cavity-nesting that do not excavate their own nests but instead occupy pre-existing cavities. Colony founding is likely haplometrotic (single ) or possibly pleometrotic (multiple queens). Workers are foragers, though specific foraging behaviors for T. caguatan have not been documented. The species is not known to be a slave-maker, unlike some related Temnothorax species.

Ecological Role

As a small cavity-nesting , T. caguatan likely contributes to through scavenging and on small . It may serve as for ant and insectivorous vertebrates. Its nest site preferences in pre-existing cavities suggest minimal direct impact on wood decomposition .
