Myrmicaria buenaventei

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Endemic to Mt. Palali in Nueva Vizcaya Province, Luzon Island, Philippines. Found at high altitudes (890-1,436m) in mossy forest zone with cold and wet conditions ^[1][2].
• Colony Type: Colony structure is unconfirmed. No published data on queen number or colony size in the wild.
• Size & Growth:
  • Queen: Unknown, queen not described in original species description
  • Worker: 4.96-7.17mm total length ^[1]
  • Colony: Unknown, no wild colony data available
  • Growth: Unknown
  • Development: Unconfirmed, no development data available for this species (Development time is unstudied.)
• Antkeeping:
  • Temperature: Cooler conditions than most tropical ants. Based on high-altitude mossy forest habitat, aim for 18-22°C with stable temperatures. Avoid overheating.
  • Humidity: High humidity required. Mossy forest conditions suggest 70-85% humidity with consistently moist substrate.
  • Diapause: Unknown, no published data on seasonal behavior. High-altitude tropical location may not require true hibernation, but cooler seasonal temperatures may cause reduced activity.
  • Nesting: Likely nests in soil or rotting wood in damp, shaded locations. A naturalistic setup with moist substrate or a Y-tong/plaster nest with good humidity retention would be appropriate.
• Behavior: Behavior is unstudied in captivity. Based on genus typical patterns, they are likely ground-nesting ants with moderate activity levels. Escape prevention should be moderate, workers are a manageable 5-7mm size, not tiny enough to require fine mesh, but standard barriers are recommended. This species has a sting as the primary defense mechanism, inheriting this from the Solenopsidini tribe.
• Common Issues: high-altitude habitat means they may not tolerate warm conditions, keep cool, specific humidity needs are unknown, start with high humidity and adjust based on colony health, no captive husbandry data exists, this is a species for experienced keepers willing to experiment, very limited distribution in the wild, ensure any colony was legally obtained

Discovery and Taxonomy

Myrmicaria buenaventei was formally described in 2018 by Herbert Zettel, Alice Laciny, and colleagues. The species was dedicated to Perry A.C. Buenavente of the National Museum of Natural History in Manila, who discovered this remarkable species during field work on Mt. Palali. The type specimens were collected between January 9-16,2010,at elevations ranging from 890 to 1,436 meters above sea level. This makes M. buenaventei one of the more recently described Philippine ant species, highlighting how little we still know about the ant fauna of these islands ^[1].

Identification and Morphology

This species can be identified by several distinctive features. The pronotum (the first segment of the mesosoma) has characteristic curved (arcuate) rugae on its dorsal surface. The anteroventral teeth of the pronotum are prominent, though they may be shorter in the smallest workers. The propodeal spines are notably long, directed backward and slightly upward, continuing the dorsal outline of the propodeum before curving up. The petiole has a long peduncle (the stalk connecting the node to the body), and the base of the first gaster segment is smooth, lacking the striation seen in some related species. Workers are pale yellow overall, with light brown on the mandibles, antenna tips, and gaster segments. All body setae are white ^[1].

Distribution and Habitat

Myrmicaria buenaventei is known only from Mt. Palali in Nueva Vizcaya Province on Luzon Island, Philippines. This restricted distribution makes it a particularly interesting species for antkeepers interested in Philippine biodiversity. The altitudinal range of 890-1,436 meters places it in the mossy forest zone, characterized by cold temperatures, high humidity, and abundant moss growth. This is a relatively cool and wet environment compared to typical lowland tropical conditions. The species has been collected in January, which is the dry season in the Philippines, but the mossy forest habitat would maintain moisture year-round ^[1].

Keeping Myrmicaria buenaventei

This is a species for advanced antkeepers. Since no captive husbandry information exists, you will need to experiment carefully. Based on the natural habitat, provide cooler temperatures than most tropical ants, aim for 18-22°C and avoid temperatures above 25°C. High humidity is essential, likely 70-85%. Use a naturalistic setup with consistently moist substrate, or a Y-tong/plaster nest that retains moisture well. Feed a varied diet including protein sources (small insects, mealworms) and sugar water or honey. Start with standard colony setup protocols and adjust based on colony behavior and health. This species is best suited for keepers who enjoy the challenge of establishing care protocols for newly described species.

Similar Philippine Myrmicaria

The Philippines hosts several Myrmicaria species, many of which are also endemic to specific islands or mountain ranges. The genus Myrmicaria belongs to the tribe Solenopsidini and is characterized by their medium size, often with distinctive spines and sculpturing. M. buenaventei is distinguished from other Philippine species by its combination of arcuate pronotal rugae, prominent anteroventral teeth, and the smooth base of the gaster. Other Myrmicaria in the Philippines include Myrmicaria nigra and Myrmicaria ruginota, but these have different distributions and morphological features. For accurate identification, compare your specimens to the original description by Zettel et al. (2018) ^[1].
