FIGURE 8 Chaetae bank, it is a collection of SEM photographs of
different chaetae found along the body, the chaetae are representatives
of their shapes and sizes, but not of their position in the body,
therefore a given shape and size represented by a photo in the bank may
occur in different parts of the body. A, habitus P. fallaciosussp. n. ; B, chaetae bank. 1 – Bulb sensillum (usually found in
the apex of ant IV); 2 – Microsensillum (e.g. , Aai on the apical
organ of Ant. III); 3 – Macrochaeta, curved with blunt tip (often
associated to bulb sensillum on the apex of Ant. IV); 4 – Bristlelike
mesochaeta; 5 – Smooth macrochaetae; 6 – Microsensillum with blunt
apex (occurs in pairs on the Ant. III apical organ); 7 – Semi globular
microsensillum; 8 – Spiniform mesochaeta
9 – Smooth curved mesochaeta; 10 – Smooth stout macrochaeta; 11 –
Oval organ; 12 – Pre tarsal spine (other groups present a microchaeta
instead); 13 – Slender spinelike mesochaeta; 14 – Smooth stout
mesochaeta; 15 – Strongly spinelike macrochaeta (e.g. ,
metatrochanteral spine); 16 – Slender smooth macrochaeta; 17 – Smooth
strong macrochaeta (similar to 10); 18 – Slender smooth microchaeta; 19
– Smooth stout microchaeta; 20 – Curved spinelike microchaeta; 21 –
Bristlelike microchaeta; 22 – Spinelike mesochaeta; 23 – J-shaped
blunt mesosensillum; 24 – Smooth mesochaeta; 25 – Heavily spiniform
mesochaeta (similar to 8); 26 – Slender smooth mesochaeta; 27 – Smooth
broad macrochaeta (similar to 10 and 17, but longer); 28 – Featherlike
macrochaeta (subanal appendage); 29 – Broad lanceolate macrochaeta
(subanal appendages, sometimes ciliated); 30 – Broad smooth
macrochaeta; 31 - Trichobothria
