Apomyrma stygia Brown, Gotwald & Levieux 
Length (through spiracles) about 2.3 mm. Moderately slender; 
abdomen elongate-ellipsoidal ; posterior end narrowly rounded ; thorax 
slightly curved ventrally, its diameter decreasing rapidly toward the 
anterior end; anterior half of prothorax forming a nearly hairless 
“broken” neck. Anus terminal with 2 lips, the posterior lip larger. 
Spiracles minute. Eleven differentiated somites. Integument appar- 
ently without spinules. Body hairs numerous, very short (0.02-0.06 
mm long), the longest in a transverse band around the middle of 
each somite. Head small ; cranium transversely subelliptical in an- 
terior view ; breadth equal to length ; due to the narrowness of the 
lab rum and the constriction of their bases, the maxillae and labium 
appear prominent and flaring. Head hairs few [all hairs broken on 
our material]. Antennae small, slightly raised, each with 2 minute 
sensilla. Labrum narrow and elongate-parabolic, with the base dilated ; 
anterior surface with 6 irregularly placed sensilla; ventral border 
with 4 sensilla; posterior surface without sensilla but with a few 
relatively long spinules, isolated distally and in short arcuate rows 
basally. Mandibles feebly sclerotized; basal abruptly dilated 
laterally, distal Y narrow, slightly curved medially and posteriorly 
into an apical tooth ; with 2 small acute subapical teeth on the medial 
border; anterior surface smooth. Maxillae lobose; apparently with- 
out spinules ; palp a stout peg with 5 sensilla ( 1 large and encapsu- 
lated, 1 bearing a long peg) ; galea slender and digitiform. Labium 
about half as wide as head; apparently without spinules; palp a 
low knob with 3 sensilla; opening of sericteries wide. Hypopharynx 
apparently without spinules. 
Very Young Larva. Length (through spiracles) about 0.7 mm. 
Subcylindrical, slightly attenuated anteriorly and slightly curved 
ventrally. Anus terminal, without lips. Apparently without integu- 
mentary spinules. Body hairs very few, simple, very short (0.004- 
0.012 mm long), in a band around the middle of each somite. Head
