Working with an idealized cylindrical model of a setule, Huajian Gao and Haimin Yao of the Max Planck Institute for Metals Research in Stuttgart, Germany, determined that the tip of such a hair should modestly dimple inward to achieve the greatest adhesion.
Proximally, the setules lay flat against the shaft, and their tips touch the base of the next setule.
Secondary processes long; thin setules arranged in two distinct rows along length of setal shaft; setule density and distances between rows variable.
It would have been desirable to record both the length and the separation distance of these setules, but they almost always became twisted in SEM preparations and were therefore not practically measurable.
Endopod two-segmented, barely reaching tip of EXP2, with spinular ornamentation as shown; ENP1 without armature; ENP2 with one strong inner seta with comb-like tip, two apical setae with outer spinules medially and with setules distally and along inner margin, and one outer apical bare spine.
1C) slightly longer than wide [111 (105-120) x 99 (90-110) [micro]m], with 6 plumose setae (seta I absent) and short row of setules along inner margin.
1A-F and 3 A), the plumose setae are smaller, with sparse setules in relation to juveniles (Fig.
On legs II and III (Figs 20, 23) setae with adhering setules, making an impression of seta being nude, are also present.
Dactylus incompletely fused with unguis, with fine ventral setules, combined being shorter than propodus.
Dorsal setae on idiosoma, 16 pairs, all with long setules on their entire lengths and ranging in lengths from 30-42um, DS=33-42; PDS=33-42; fD=32 (Fig.
