These gallieniellids are small spiders with 8 eyes in two straight or almost straight rows, The name Oreo comes from the black and white cookie of that name, referring to the black and white pattern on the abdomen. Males differ from other Gallieniellid genera Meedo by having some leg spines, Peeto by lacking cheliceral teeth, and from those of Neato by the shape of the male palp. Carapace light brown with black net pattern, abdomen dark gray with pairs of lateral spots, almost conjoined, extending to sides but not underneath. The species name is from the lake near Birdsville where it was found. ♀ 3.5mm ♂ 3mm
