Proceratiinae
Guides
Discothyrea testacea
Discothyrea testacea is a species of ant in the subfamily Proceratiinae, described by Roger in 1863. It is native to the Southeastern United States, with additional records from Caribbean islands and the Yucatán Peninsula. The genus Discothyrea is characterized by a highly specialized morphology and cryptic lifestyle, making species in this genus poorly represented in museum collections.
Proceratium
Hairy Curltail Ants
Proceratium is a rare genus of ants in the subfamily Proceratiinae and the type genus of tribe Proceratiini. These ants are distributed across temperate and tropical regions worldwide but are infrequently collected due to their cryptobiotic lifestyle. Colonies are small, typically containing fewer than 200 individuals. Some species are specialist predators of arthropod eggs, particularly spider eggs. The genus is notable for its ability to curl the abdomen dorsally more than 90 degrees relative to the body axis.
Proceratium chickasaw
Proceratium chickasaw is a species of ant in the subfamily Proceratiinae, described by de Andrade in 2003. Members of this genus are small, cryptic ants known for specialized predatory behaviors. The species name refers to the Chickasaw people, indigenous to the southeastern United States. Like other Proceratium species, it likely exhibits specialized egg predation behaviors, though direct observations of this species remain limited.
Proceratium crassicorne
Fat Curltail Ant
Proceratium crassicorne is a rarely encountered ant species described by Emery in 1895. It belongs to the genus Proceratium, a group of specialized predatory ants known for their distinctive elongated petiole and furtive foraging habits. The species epithet 'crassicorne' refers to its notably thick antennae. Like other members of its genus, it is likely a cryptic predator with specific habitat requirements, though detailed biological studies remain limited.
Proceratium croceum
Proceratium croceum is a small, cryptic ant species in the subfamily Proceratiinae. It belongs to a genus of specialized predators that exhibit unusual foraging behaviors. The species is known from limited observations in the eastern United States. Like other Proceratium species, it likely possesses a distinctive elongated petiole and modified mandibles for capturing specific prey.
Proceratium pergandei
Pergandei-clade Hairy Curltail Ants
Proceratium pergandei is a species of ant in the subfamily Proceratiinae, endemic to the Central and Eastern United States. It belongs to a genus of small, cryptic ants commonly known as 'curltail ants' for their distinctive abdominal morphology. Members of the Pergandei-clade within Proceratium are characterized by dense pilosity (hairiness) compared to other congeners.
Proceratium silaceum
Silaceum-clade Hairy Curltail Ant
Proceratium silaceum is a rare ant species first described by Roger in 1863. It belongs to the Proceratiinae subfamily, a group characterized by cryptobiotic lifestyles that make them infrequently collected. The species has been recorded in South America, with distribution data documented in Brazil. It is part of the P. micrommatum clade within the genus Proceratium.
