Lordomyrma acuminata

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Papua New Guinea, tropical rainforest environments in the Australasian region. The type locality is along the north coast of former Kaiser Wilhelms Land (141°E-148°E) ^[1].
• Colony Type: Colony structure is unconfirmed. No documented data on queen number or colony social structure exists for this species.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no direct development data available for this species. (Development timeline has not been studied.)
• Antkeeping:
  • Temperature: Temperature requirements are unconfirmed. As a tropical species from Papua New Guinea, they likely require warm conditions. Monitor colony activity and adjust as needed.
  • Humidity: Humidity requirements are unconfirmed. As a tropical species from Papua New Guinea, they likely prefer humid conditions. Provide a water source and avoid dry setups.
  • Diapause: No diapause required, as a tropical species from Papua New Guinea, they do not experience cold winters.
  • Nesting: Nesting preferences are unconfirmed for this species. Based on genus-level patterns, they likely nest in rotting wood or moist soil in shaded forest habitats ^[2].
• Behavior: Behavior is not well documented for this species. Based on genus-level observations from AntWiki, Lordomyrma species are generally non-aggressive. Escape risk is moderate, use standard barrier methods ^[2]. This species belongs to the Myrmicinae subfamily, which typically have functional stingers capable of delivering venom.
• Common Issues: limited availability, this species is rarely available in the antkeeping hobby due to restricted range, no established husbandry guidelines, keepers will be pioneering care methods, tropical humidity requirements mean setups must not dry out, wild-caught colonies may harbor parasites from Papua New Guinea, no species-specific data on optimal care conditions

Natural History and Distribution

Lordomyrma acuminata is endemic to Papua New Guinea in the Australasian region. The type specimens were collected during the Kaiserin-Augustafluss Expedition with the type locality likely being the north coast of the former German colony of Kaiser Wilhelms Land, between 141°E and 148°E longitude ^[1]. Originally described in 1912 as a variety of L. cryptocera, it was elevated to full species rank in 2009 ^[1]. The exact nesting habits in the wild are not documented, but the genus Lordomyrma generally includes species that nest in rotting wood, under bark, or in moist soil in shaded forest habitats ^[2].

Housing and Nest Setup

Since specific care requirements are unconfirmed for this species, start with standard setups and adjust based on colony behavior. Test tube setups with water reservoirs work well for founding colonies and small groups. The water reservoir provides constant humidity and a drinking source. For established colonies, Y-tong nests or plaster nests that retain moisture are suitable options. Avoid setups that can dry out quickly. Monitor how workers respond to humidity levels. Provide a foraging area with access to protein and sugar sources.

Feeding and Diet

Diet preferences are not documented for this specific species. Based on typical Myrmicinae behavior, they likely accept a varied diet including small insects, honeydew, and sugar sources. Offer protein sources such as small crickets, mealworms, or other small arthropods. Sugar water or honey can be provided as an energy source. Since this is a relatively unknown species in captivity, observe acceptance of different food types and adjust accordingly.

Temperature and Seasonal Care

As a tropical species from Papua New Guinea, Lordomyrma acuminata likely requires warm conditions year-round. Unlike temperate species, they do not require hibernation or diapause periods. Room temperature within the low-to-mid 20s Celsius is likely suitable. If your room is cooler, use a heating cable on one side of the nest to create a temperature gradient. Monitor colony activity, workers should be active and foraging.

Colony Development and Growth

Specific development timeline data is not available for this species. Initial workers (nanitics) will likely be smaller than mature workers. Since this species is rarely kept in captivity, keepers will need to document their own observations to build husbandry knowledge for the antkeeping community.
