Ooceraea quadridentata

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Nam Kar Nature Reserve, Dak Lak Province, Vietnam at approximately 545m elevation, in highly disturbed bamboo-mixed evergreen forest patches near forest edges, nesting inside partly rotten tree stumps ^[1]. Also recorded in northeastern and eastern Thailand ^[3].
• Colony Type: Colony structure is unconfirmed. The only collected fragment had 16 workers with no queens, males, or immatures observed ^[1]. Ergatoid queens are known in related species, but not documented here ^[4].
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements documented ^[1]
  • Worker: Size data unavailable, no total length measurements documented ^[1]
  • Colony: Unknown, a wild fragment contained 16 workers ^[1]
  • Growth: Unknown
  • Development: Unconfirmed, no direct observations exist (No data on founding, brood development, or growth timeline)
• Antkeeping:
  • Temperature: Based on tropical habitat, keep warm around 22-28°C ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, mimicking rotten wood conditions ^[1]
  • Diapause: No, tropical species do not require hibernation, inferred from geographic range
  • Nesting: Natural nesting in rotten stumps, in captivity, use naturalistic setups with rotting wood or humidified plaster nests ^[1]
• Behavior: No specific behavioral studies exist. As doryline ants, they may be predatory. Workers are blind and rely on chemical trails ^[1]. Escape risk is moderate due to small size. Temperament is unknown but likely not aggressive toward humans.
• Common Issues: this species is extremely rare in the hobby with no established captive breeding lines, obtaining a colony may be impossible., no information exists on what foods this species accepts in captivity., blind workers may have difficulty locating food in open foraging areas., no data on founding behavior means successful colony establishment is uncertain., tropical species may be sensitive to temperature drops, keep warm year-round.

Identification and Distinguishing Features

Ooceraea quadridentata can be identified by the propodeum, which has two pairs of denticles, one larger triangular pair and one smaller digitiform pair ^[1][2]. Workers have 11-segmented antennae and lack compound eyes and ocelli ^[1]. The body is dark reddish-brown with paler antennae and legs, and the head has a foveolate-reticulate sculpture ^[1].

Natural History and Habitat

This species is known from Southeast Asia, including Vietnam's Central Highlands and parts of Thailand ^[1][3]. It inhabits disturbed forest patches near forest edges, nesting inside partly rotten tree stumps on the forest floor ^[1]. Thai specimens were found in rotten logs in plantation and dry evergreen forests ^[3].

Related Species and Phylogeny

Ooceraea quadridentata is part of a recently described group of Ooceraea species from Southeast Asia. It is closely related to the queenless clonal raider ant Ooceraea biroi, but does not share its clonal reproduction ^[4]. Other related species include O. hainingensis from China, which has ergatoid queens ^[4].

Challenges for Antkeepers

This species is rare in both science and the hobby, described only in 2018 with few known locations ^[1]. No captive breeding lines exist, and care requirements are largely unknown. Blind workers may require specialized setups, and success is uncertain for all but the most experienced keepers.
