setae, dorsal surface with many long curved ones, those 
near the apex somewhat heavier and blunter than the 
remainder ; p.a.o. of 14 complex lobed papillae, arranged 
in an elongate ellipse; claw untoothed, apical filament of 
gradually acuminate empodial appendage exceeding level 
of apex of unguis ; integument of antennal bases not clearly 
distinguishable from that of remainder of head; no furcula 
remnant visible; pseudocellar formula: 32/123/333330; no 
ventral pseudocelli seen; bases of coxae each with a pair 
of pseudocelli. 
Variation and Discussion. The sensory knobs of the 
third antennal sense organ vary from more or less triangu- 
lar as described to an almost circular shape. Most speci- 
mens have triangular or oval organs or some compromise 
between these. The number of pseudocelli varies a good 
deal. The condition described for the holotype is that 
found on the majority of adult specimens. The first three 
abdominal segments may have four or, rarely, five pseudo- 
celli. The coxal bases often appear to have a single pseu- 
docellus, but this may be due to the structure of this organ 
which tends to hide the pseudocelli in integumentary folds. 
The number of lobes in the P.A.O. varies from 12 to 18. 
This species is a member of the ambulans group and is 
unique in its absence of ventral pseudocelli. Among the 
species of this group it appears to be most closely related 
to boldorii and stillicidii, but differs from both of these by 
the complete absence of a ventral organ on the adult 
males, in addition to the distribution of the pseudocelli.
