Stictoponera lattkei

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Rorathang, East Sikkim, India at 560m elevation, dense forest with agricultural land. Average daily temperature around 30°C ^[1].
• Colony Type: Unknown – only workers have been collected, the queen and male have never been seen ^[1]. Based on genus patterns, colonies are likely single-queen once a queen is found, but this is pure speculation.
• Size & Growth:
  • Queen: Unknown – queen has not been described ^[1]
  • Worker: 5.08–5.47mm total length ^[1]
  • Colony: Unknown – only six workers are known from the type series ^[1]
  • Growth: Unknown
  • Development: Unknown – no development data exists. Based on related Ectatomminae species, maybe 6–10 weeks at warm temperatures, but this is untested. (Development timeline is completely unconfirmed. Related tropical Ectatomminae species often develop in 6–8 weeks at 26–28°C.)
• Antkeeping:
  • Temperature: Keep at 24–28°C, based on the collection site's average of 30°C ^[1]. Provide a gentle gradient so the ants can choose. Avoid prolonged temperatures below 20°C.
  • Humidity: Moderate to high humidity (around 60–80%). The Sikkim forest is humid, so keep the nest substrate moist but not waterlogged. Provide a water source in the outworld.
  • Diapause: Unlikely – the species comes from a tropical/subtropical area with year-round warmth. A slight cool-down in winter months may be tried but is not necessary.
  • Nesting: Likely prefers rotting wood, under bark, or crevices in tree trunks – workers were handpicked from a tree trunk ^[1]. In captivity, offer pieces of rotting wood, cork, or a Y-tong/plaster nest with good moisture retention. Include vertical climbing surfaces.
• Behavior: Behavior is undocumented, but related Stictoponera species are predatory or omnivorous, foraging on tree trunks and leaf litter. As an Ectatomminae, it has a functional stinger and can deliver a painful sting if provoked. Workers are moderately sized and probably defend the nest actively. Escape risk is moderate – use standard formicarium precautions.
• Common Issues: very limited availability – only described in 2023 and rarely found, no captive sources exist., queen unknown – cannot start new colonies until a queen is discovered and studied., no care data – keepers must experiment with temperature, humidity, and diet, risking colony loss., wild colonies may carry parasites or diseases since only six workers are known., semi-arboreal lifestyle – may need vertical space and climbing structures in the outworld.

Species Discovery and Status

Stictoponera lattkei was first described in 2023 by Dhadwal and Bharti, making it one of the newest ant species known to science ^[1]. The type series contains only six workers, all collected from a single tree trunk at Rorathang, East Sikkim, India, at 560m elevation ^[1]. The species is named after Professor John E. Lattke, a distinguished entomologist at the Federal University of Paraná, Brazil ^[1]. The queen and male castes have never been found, so almost everything about its biology remains a mystery ^[1]. This species is strictly for experienced antkeepers who are willing to experiment with a completely unknown species.

Appearance and Identification

Workers measure 5.08–5.47mm in total length, making them a moderately sized ant ^[1]. The body is ferruginous (rusty brown) with a noticeably darker gaster (hind part of the abdomen) ^[1]. The body has very few hairs (weakly pilose) – the top of the middle body (mesosoma) and the petiole have only one or two hairs, while the antenna scapes and gaster have short, lying hairs ^[1]. Key features include large, round eyes placed toward the rear of the head, tiny denticles on the front of the pronotum, a small triangular bump on the propodeum (rear of the middle body), and a slender, curved spine on each middle leg (metacoxa) ^[1]. The underside of the petiole has a polygonal shape with a little tooth pointing forward ^[1]. These details help tell it apart from similar species like Stictoponera menadensis and Stictoponera bicolor ^[1].

Natural Habitat and Temperature

The only known location is Rorathang in East Sikkim, India, at an elevation of about 560m ^[1]. The area is dense forest mixed with farmland, and the average daytime temperature is around 30°C ^[1]. This indicates a warm, humid, tropical climate. In captivity, keep the nest at 24–28°C, with a heat gradient so ants can choose. Don't let temperatures drop below 20°C for long periods. A small heating cable on one side of the nest works well.

Foraging and Diet

Workers were collected from a tree trunk while foraging together with Camponotus parius ^[1]. This suggests they search for food above ground, on bark or in low vegetation. What they eat in the wild is unknown, but most Stictoponera species are hunters or scavengers. In captivity, offer small live prey like fruit flies, pinhead crickets, and small mealworms. They will also likely accept sugary liquids like honey or sugar water, but protein should be the main part of the diet. Feed every 2–3 days and remove leftovers to stop mold.

Nesting Preferences

Because all known workers were taken from a tree trunk, Stictoponera lattkei probably nests under bark, inside rotting wood, or in crevices of tree branches ^[1]. This is typical for the genus. In a formicarium, give them a naturalistic setup with pieces of rotting wood, cork bark, or a Y-tong/plaster nest that holds moisture well. Since they were found climbing on trunks, include vertical surfaces like bark slabs or mesh for climbing.

Stinger and Defense

As a member of the ant subfamily Ectatomminae (tribe Ectatommini), Stictoponera lattkei has a fully functional stinger. This means it can give a painful sting if the colony is attacked or handled roughly. While not out‑of‑the‑norm aggressive, you should disturb the nest as little as possible and use caution during maintenance. The sting is not medically dangerous for most healthy people, but it can hurt and cause redness. Keepers with allergies should take extra care.
