The levels of sterol esters in labial palps
were in general higher than those found in the digestive gland and gonad, especially during the spring-summer, a period in which they accumulate between 14% and 27% of TC (Table 4A).
Neither male charged his palps
with sperm during the courtship, indicating that males charged their palps
before encountering a female.
Perhaps the extended palps
of adult females limit the access of subsequently settling Osedax larvae to bone surfaces (Fig.
paulista were an increment in size, and with the appearance and development of certain structures upon every subsequent instar, including: increase in the density of body spines and papillae; presence of body setae on fifth-instar larvae; the opening of body spiracles in second instar larvae; 2 types of body shape in fifth-instar larvae; the presence of a lateral tooth in the mandibles of fourth- and fifth-instar larvae; presence of spines on the maxilla of fifth-instar larvae; alterations in the shape of galea and palps
upon third-instar larvae from a cluster of sensilla to a conical elevation; and the appearance of spines on the postmentum upon fourth-instar larvae.
very slightly broader than postpedicels, with 4 or 5 short bristles (longest being only 0.
Transitory and undispersed light is produced when direct physical stimulation or freshwater are applied to the peristomial palps
, feeding structures on the dorsal surface of region B, and notopodia of region C.
4B), with 2 setaceous sensilla, one near base of palp
and another near galea; maxillary palp
The labium consisted of 2 labial palps
with a sensillum styloconicum at the apex, a sensillum chaeticum in the center (Fig.
A pair of round palps
was present on both sides of the head (Fig.
puniceus shows simple morphology; it has paired palps
and pygidial lobes, but no eyespots, nuchal organs, statocysts, or ciliary rings dorsoanteriorly--an exceptional finding in this group.
Left male palps
in ventral view are used for describing the origin points of the embolus, apophyses and conductor on the tegulum.
Most adult mites possess the usual arachnoid appendages, jaws, palps
at the front end, and four pairs of legs.
