Cephalic
index (CI). Head width x 100/head length |
| |
Eye length
(EL). Maximum length of eye with head in full face view (fig.
1) |
| |
Maximum
head length (MHL). The maximum measurable length of the head,
positioned in perfect full face view. (fig.

| |
Maximum
head width (MHW). The maximum width of the head, positioned
in full face view, measured across the widest portion of the
head (workers). In the male caste the measurement is taken in
full face view, and measured across the eyes. (fig.

Petiole
width (PW). Petiole measured in dorsal view across it's greatest
measurable width (fig.
4) |
| |
Pilosity.
The longer, stouter hair hairs or setae, outstanding form the
cuticular surface. Terminology to indicate degree of inclination

Postpetiole
width (PPW). Postpetiole measured across it's greatest measurable
width in dorsal view (fig.
