Lordomyrma limatula

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Philippines (Leyte Island), collected from the Lago-lago River area near Baybay at coordinates 10°40'N,124°49'E ^[1]. The region features tropical forest environments.
• Colony Type: Unknown, colony structure has never been documented
• Size & Growth:
  • Queen: 3.9-4.0mm ^[1]
  • Worker: 3.0-3.4mm ^[1]
  • Colony: Unknown, no colony size data exists
  • Growth: Unknown, no development data exists
  • Development: Unknown, no development timeline has been documented (No brood development data exists for this species. Related Lordomyrma species likely follow a standard Myrmicinae development timeline, but confidence is very low.)
• Antkeeping:
  • Temperature: Unknown, no thermal data exists. Based on its Philippine origin (tropical), warm conditions in the low-to-mid 20s°C may be appropriate. Start around 24-26°C and observe colony behavior.
  • Humidity: Unknown, no humidity data exists. Based on related species and Philippine climate, high humidity (70-85%) may be needed. Keep the nest substrate consistently moist but not waterlogged.
  • Diapause: Unknown, no overwintering data exists. As a tropical species from the Philippines, it likely does not require a diapause period, but this is unconfirmed.
  • Nesting: Unknown, no natural nesting observations exist. Related Lordomyrma species typically nest in rotting wood or soil in shaded forest areas. A naturalistic setup with moist substrate or a Y-tong/plaster nest with good humidity retention would be a reasonable starting point.
• Behavior: Completely unstudied, no behavioral observations exist in scientific literature. Based on related Lordomyrma species, they are likely docile, non-aggressive ants that forage quietly. Their small size (3-4mm) means escape prevention is important, use fine mesh barriers. Most small Myrmicinae can sting though it may not penetrate human skin.
• Common Issues: this species has never been kept in captivity, no established care protocols exist, no biological data means all recommendations are educated guesses based on related species, extremely rare in the hobby, finding a colony would be exceptionally difficult, without proper humidity, colonies will likely fail quickly, growth will likely be slow, requiring patience and experience with delicate species

Species Discovery and Rarity

Lordomyrma limatula was described in 2012 by Robert W. Taylor, making it one of the most recently described ant species available to study ^[1]. The entire known population comes from a single collection event on Leyte Island in the Philippines, the Lago-lago River near the Leyte State University in Baybay ^[1]. The type series consists of the holotype worker,13 worker paratypes, and 11 queen paratypes ^[1]. Every specimen in existence worldwide was collected during one day in March 2005 by collectors H. Zettel and C. Pangantihon ^[1]. This extreme rarity makes the species exceptionally difficult to obtain for antkeeping, and no established captive populations exist in the hobby.

Appearance and Identification

Workers measure 3.0-3.4mm in total length, making them small but not tiny ants ^[1]. The most distinctive feature is the smooth, polished promesonotum, this is what the species name 'limatula' refers to (from Latin, meaning 'polished') ^[1]. The body is uniformly rich sienna-brown in color, with antennae and legs slightly lighter in shade ^[1]. Unlike similar species like Lordomyrma diwata, L. limatula has relatively reduced sculpturation, meaning the body surface is smoother and shinier ^[1]. The propodeal spines are present but proportionally shorter than in related species like Lordomyrma azumai ^[1]. Queens are slightly larger at 3.9-4.0mm and share the same polished appearance ^[1].

Related Species and Context

Lordomyrma limatula is similar in conformation to two other Lordomyrma species: Lordomyrma azumai from Japan and Lordomyrma diwata from elsewhere in the Philippines ^[1][2]. However, it can be distinguished by its reduced sculpturation and the polished promesonotum that the other species lack ^[1]. The genus Lordomyrma contains around 40 described species distributed across Asia and the Pacific region. Most species are poorly studied, with biology data lacking for nearly all of them. Lordomyrma azumai from Japan is the most commonly studied species in the genus, but even it has limited biological documentation. Keepers interested in L. limatula have almost no direct care guidance and must rely on inference from general Myrmicinae patterns and the limited data available from related species.

Housing and Setup Recommendations

Since no captive care data exists for this species, any recommendations are educated guesses based on related species and general Myrmicinae husbandry. A naturalistic setup with moist substrate would be a reasonable starting point, think damp forest floor conditions. A Y-tong (AAC) nest or plaster nest with good humidity retention would work well, as these hold moisture consistently. Given the Philippine origin and the smooth, polished body suggesting adaptation to humid conditions, aim for high humidity around 70-85%. Temperature should be warm, start around 24-26°C and adjust based on colony activity. The small worker size (3mm) means escape prevention should be taken seriously, use fine mesh barriers on any openings. Because this is an expert-level species with no established protocols, only experienced keepers should attempt to keep it, and they should be prepared for experimental husbandry.

Feeding and Diet

No dietary data exists for this species. As a Myrmicinae ant, it likely has a typical omnivorous diet similar to most small forest-floor ants, likely accepting sugar sources, honeydew, and small protein items like insects. Related Lordomyrma species are not known to be specialized predators, so a standard ant diet of sugar water or honey and small insects would be a reasonable starting point. Since nothing is confirmed for this species, keepers should experiment cautiously and observe acceptance carefully. Start with small amounts of sugar water and small prey items like fruit flies or pinhead crickets, and remove uneaten food promptly to prevent mold.
