The spiracles of adult females of Apiomorpha are described and classified into 4 basic types. The atrial orifice of the spiracles is guarded typically by lips in the form of 3 simple, valve-like plates (typical trilabiate type), but these plates may be moderately to elaborately developed (fimbriate trilabiate type) or greatly reduced (synlabiate type). In A. hilli Froggatt no atrium or lips are present, and the tracheal apertures open onto a honeycomb-like plate (reticulate type). Both pairs of spiracles (mesothoracic and metathoracic) have a similar structure in each species.
In Apiomorpha there is a relationship between spiracular structure and the intrageneric groupings of the species: species considered to be closely related based on other characters generally have spiracles of similar form.
