Female (ergatoid?) (Fig. 7b). Length about 6 mm. 
Resembling the worker. The ocelli are probably present but 
hidden by one of several air-bubbles which are scattered over the 
body. Eyes but little larger than tbose of the worker. Thorax rather 
stout, with distinct mesonotum, scutellum and metanotum, but 
with no clear indications of having borne wings. The epinotum and 
petiole resemble the corresponding parts of the worker. Surface of 
body opaque, its chitinous integument much decomposed. Hairs absent. 
Color deep black throughout. 
Described from a single worker in the Geolog. Inst. Koenigsberg 
ColL (no number) and a single female (K 5122) in the Klebs Coli.

genus Platythyrea, which has a wide distribution in the tropics of 
both hemispheres.
