|Based on Blaimer et al., 2016. Note only selected Acropyga species are included, and undescribed species are excluded.|
This is the only species of Acropyga that is endemic to Australia. It is widespread, occurring mainly at drier forested sites and less commonly in wet sclerophyll and rainforest. Nests are in soil under rocks. It is the only known species of Acropyga that tend non-mealybugs (in the family Ortheziidae rather than Pseudococcidae).
LaPolla (2004) - Worker: 11 segmented antennae; mesosomal dorsum with short appressed hairs, giving it a bare appearance; mesonotum broadly rounded, higher than propodeum; head width > 0.6 mm. Queen: As in worker, with modifications expected for caste. Male: 12 segmented antennae; parameres taper toward apices where many shorter hairs bend toward penis valves; in dorsal view parameres form "v" shape from apex to the base. Compare with Acropyga acutiventris and Acropyga dubia.
A. myops can be separated from other Australian species by the presence of short erect hairs on the scapes and mesosomal dorsum, the smooth mandibles which lack striations and the large size (head width greater than 0.6mm).

Head: yellow; head covered in a layer of dense appressed hairs; head about as long as broad to slightly longer than broad; posterior margin entire to slightly concave; 11 segmented, incrassate antennae; scape reaches or slightly surpasses (less than half length of pedicel) posterior margin; clypeus broad, medially convex, with longer, erect hairs; mandible broad with 5-6 teeth; small, indistinct tooth often at basal angle; 3rd tooth from apical smaller than others; a short diastema between 4th and 5th tooth (numbered from apical); dorsal surface of mandible covered in many erect hairs (≥ 20 hairs); hairs close to masticatory margin often extend passed length of teeth; inner mandibular margin parallel with anterior clypeal margin. Mesosoma: yellow; in lateral view, pronotum rises steeply toward mesonotum; pronotum covered in dense layer of short appressed to suberect hairs; mesonotum dorsum broadly rounded toward metanotal area; mesonotum covered in dense layer of short appressed to suberect hairs; mesonotum higher than propodeum; metanotal area distinct; propodeum covered in dense layer of short appressed hairs, gently rounded toward steep declivity.
