For microscopic study of entire individuals, specimens were cleared in Marc André I fluid
(Christiansen & Bellinger 1998), then dissected to separate the head, legs, and furcula from the rest of the body.
Mandibles, maxillae and labium were pulled from the head capsule before mounting. Legs were mounted as separate
pairs, each pair under a separate cover slip. The furcula was mounted dorsal side up, and one dens was severed
at midpoint to insure that at least one mucro could be viewed in profile. The body cuticle was carefully cut along
the ventral side and cleaned of internal organs, then mounted dorsal side up under a separate cover slip. Five intact
antennae from five separate individuals of each species were removed and mounted for study of the distal parts of
the third and fourth segments. All parts were mounted in Hoyer’s medium. Slides were dried and hardened in a 60º
C oven for 2–4 days, then ringed with sealant. Specimens were examined with bright-field, differential interference-
contrast, and phase-contrast microscopes
