Nothing is known about the biology of this species.


This species is most likely to be confused with Euprenolepis thrix, but E. zeta has far less pubescence on the gaster. As in E. thrix, E. zeta does have the head wider than long, an unusual trait among Euprenolepis species. Based on overall morphological similarity, including the head shape and presence of pubescence on the gaster, it is likely that E. thrix and E. zeta are close relatives. (Lapolla 2009)

  Explore Overview of Euprenolepis biology 
Biological details regarding the small number of species within this genus are sparse. The best characterized species is Euprenolepis procera, with the following known details. It has polymorphic workers. Colonies are nomadic and on average stay in any single location less than a week. Nests contain from 500 – 5,000 workers and are opportunistically situated in suitable preformed cavities. Emigrations appear driven by the need to find their almost exclusive source of nutrients, mushrooms. Foraging takes place nocturnally. While knowledge of the remaining species is sparse, there is some indication that that polymorphism is not the norm. It is also unclear if procera is the only species, within this genus and within ants as a whole, that feed directly and almost exclusively on mushrooms.

Measurements (n=3): TL: 2.69–3.22; HW: 0.77–0.86; HL: 0.76–0.86; SL: 0.98–1.03; WL: 1.02–1.16; GL: 0.86–1.2. Indices: CI: 99–104; SI: 116–130

Head brown, with lighter yellowish-brown mandibles and funiculi; head about as long as broad. Cuticular surface shiny and smooth, with scattered erect setae and sparse pubescence that is thickest in area under the eyes. Posterior margin complete. Scapes surpass posterior margin by about length of the first four funicular segments. Scapes with erect setae and a layer of pubescence, becoming denser distally. Mesosoma brown, smooth and shiny, legs lighter, especially tarsi, which become yellowish-brown. Mesosomal dorsum with scattered erect setae of varying lengths; cuticular surface without pubescence. Pronotum rises at about 45° toward mesonotum; propodeum dorsum rounded, dome-like; declivity short, but steep. Petiole triangular with posterior face longer than anterior face; gaster brown, with scattered erect setae and a sparse layer of pubscence; cuticular surface shiny and weakly reguoreticulate.

Type Material

Holotype worker, MALAYSIA: Borneo, Sabah, Sepilok Forest Reserve, 60 m, ii.1999 (C. Brühl) (National Museum of Natural History); 1 paratype worker, same locality as holotype (Australian National Insect Collection).


The species epithet is Greek. Zeta is the sixth letter of the Greek alphabet, and this was the sixth and final new species discovered during the course of this revision.
