Sternum -a: the breast: the middle portion of the under surface of thorax, between the coxal cavities.
The name “coxal gland” needs to be carefully distinguished from “crural gland,” with which it is apt to be confused.
Orifice of coxal gland situated between the coxae of the 5th and 6th appendages.
The crural glands, which occur in many terrestrial Arthropods, are epidermal in origin and totally distinct from the coxal glands.
Orifice of coxal gland situated just behind that of the foetid gland.
coxal stylets: short, leg-like, jointed appendages on the underside of the abdominal segments in Thysanura.
The coxal excretory organs at the base of the endognaths remain and become the pituitary body.
coxal file: in some aquatic Coleoptera a series of striations just above the hind coxa of male and, perhaps, a stridulating organ.
coxal plates: plate-like expansions or dilations of the coxa: specifically in aquatic Coleoptera on the posterior pair.
Again, the basal part of the appendage is all that is left; the thyroid gland is in position a coxal gland.
