Figure 7, Apomyrma stygia sp. n., small form, wings of queen. 
femur L 0.30 mm, WL 0.94 mm, petiolar node L 0.24 mm, petiolar 
node W 0.27 mm, greatest diameter of compound eye 0.095 mm. 
Ergatoid — Two specimens from the type nest are intermediate 
between winged queens and workers from this nest series in size, and 
wings or wing stumps are absent. The mesonotum is reduced to a 
subquadrate piece. Compound eyes are present but smaller than in 
winged queens; 3 ocelli are present. 
Male, pharate adult: removed from cocoon, which is similar in 
size and color to the small-form worker cocoons with which it was 
mixed in type nest. Pupal skin partly removed by needle. Total 
length (TL) about 2.8 mm, HL about 0.4 mm, WL about 1.1 mm. 
The specimen is still pale, with compound eyes in the purple stage 
(greatest diameter 0.24 mm), and only the first faint flush of tannish 
pigmentation showing, mainly on truncal dorsum. Numerous fine 
brownish points probably indicate the presence of an abundant fine 
pilosity. Details of smaller mouthparts cannot be made out, since 
the parts are still soft and transparent, but the mandibles are 
vestigial, small and triangular, with rounded apices, separated by 
nearly the whole width of the labrum. Details of middle front of 
head also obscure, but from what can be seen, not much different 
from the worker here. Antennae 13-segmented, with very short scape, 
funicular segments varying from about as broad as long to longer 
than broad; apical segment longest. Truncus as in Fig. 19; wings 
not yet unfolded. Petiole short, much higher and broader than long.
