Fig. 2. Asketogenys acubecca new species, holotype worker, full-face 
(dorsal) view of head, only fringing pilosity shown for upper part. Drawn 
by Bente King. 
Description will be limited to details not evident from the generic 
characterization and the figures. The stippled area of Fig. 2 indi- 
cates the position of the impressed area on the vertex. Promesono- 
tum flat, with upturned lamellar margins as shown; the margins 
become less distinct posteriad on the propodeal dorsum (which is 
gently convex from side to side), and finally almost disappear just 
in front of the propodeal teeth. Posterodorsal face of petiolar node 
nearly square; disc of postpetiolar node transversely elliptical. 
Details of the mandibular bases are unknown ; presumably an erect 
basal lamella is present beneath the clypeus. The labrum is of the 
Smithistruma pattern, with paired long-subconical lobes bearing a 
pair of short spatulate trigger hairs at the apex. The mandibular 
apex, difficult to see in this case at full closure, consists of a very 
short border, nearly perpendicular to the main axis of the shaft, 
onto which are crowded a very small but acute dorsal (proximal) 
tooth (which crosses its opposite number at full closure), about six 
minute denticles, and a very small ventral (apical) tooth. This 
apical arrangement reminds one of some Epitritus species. 
Head, trunk and coxae densely reticulate -punctulate throughout, 
the individual punctulae moderately coarse and with shining bottoms, 
but the general surface prevailingly opaque, except for a weakly 
shining area on each posterior side of trunk. Clypeus, dorsal and
