Euprenolepis variegata workers are most likely to be confused with Euprenolepis wittei. The two species can be separated based on the fact that E. variegata is lighter in color, has scattered pubescence on the scapes, becoming dense distally, and longer erect setae on the gaster than those of E. wittei.

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: 2.98–3.36; HW: 0.77–0.82; HL: 0.81–0.89; SL: 1.07–1.11; WL: 1.1–1.26; GL: 1–1.21. Indices: CI: 91–96; SI: 136–140
Head brown, with scapes and mandibles lighter and funiculi much lighter becoming brownish-yellow; head about as long as broad. Cuticular surface shiny and weakly rugoreticulate, with scattered erect setae, with only small areas of pubescence along clypeal margin. Scapes with scattered pubescence and erect setae; pubescence more abundant distally. Mesosoma light brown, shiny, with legs slightly lighter. Scattered erect setae of varying lengths concentrated on posterior pronotum and anterior mesonotum. Pronotum rises at about 45° toward mesonotum; propodeum dorsum rounded, dome-like; declivity short, but steep. Petiole triangular, inclined forward, with posterior face longer than anterior face; gaster darker brown than mesosoma, with erect setae and no pubescence; cuticular surface shiny and weakly rugoreticulate.
Holotype worker, MALAYSIA: Borneo, Sabah, Danum Valley, West Trail P1, 250 m, ii.1999 (C. Brühl) (National Museum of Natural History); 2 paratype workers, same locality as holotype (Australian National Insect Collection; USNM); 1 paratype worker, MALAYSIA: Borneo, Sabah, Sepiok Forest Reserve, 60 m, ii.2000 (C. Brühl) (USNM).
The species epithet is Latin for different, in reference to its separation from E. wittei.
