Syscia

Syscia is a genus of ants belonging to the subfamily Dorylinae (formerly Cerapachyinae). These ants are primarily found in tropical and subtropical regions of the Old World, including Africa, Asia, and Australia.

Characteristics: Syscia ants are typically small to medium in size and possess a distinctive appearance. Key characteristics include:

• Morphology: They generally have a cylindrical body shape and are often reddish-brown or dark brown in color. The promesonotal suture (the seam between the pronotum and mesonotum) is often absent or indistinct.
• Mandibles: Their mandibles are typically triangular and toothed, suited for predation.
• Antennae: They have 12-segmented antennae.
• Sting: Like other dorylines, they possess a functional sting.
• Lifestyle: Syscia ants are generally thought to be subterranean or leaf-litter dwelling predators. Their colonies are often small and cryptic, making them difficult to observe in their natural habitat.

Taxonomy: The taxonomy of Syscia and related doryline genera has been subject to revision in recent years, reflecting advances in molecular phylogenetics and morphological studies. The placement of species within Syscia and its relationship to other genera within Dorylinae may continue to evolve as research progresses.

Ecology: While the ecology of many Syscia species remains poorly understood, they are believed to be specialized predators of other invertebrates, likely including other ant species or their brood. They play a role in the complex ecosystems of the forest floor.

Distribution: Syscia ants are distributed across a wide geographic range, primarily in the Old World tropics and subtropics. The precise distribution of individual species is often poorly documented due to their cryptic habits and taxonomic complexities.
