coxal file (ARTHRO: Insecta) A series of ridges on the coxa of the middle legs that by rubbing with a scraper on the tro-chanter of the hind leg produce sounds; a stridulatory apparatus.

coxal glands 1. (ARTHRO: Chelicerata) The excretory organs of arachnids; in Araneae, located opposite the coxae of the first and third legs, that function in collecting wastes into a saccule and discharging them through tubes opening behind the coxae. 2. (ARTHRO: Insecta) Variously modified eversible glandular structures at the base of the legs. 3. (ONYCHO) The nephridia of Peripatus .

coxal process (ARTHRO: Insecta) A structure of the pleuron, with which the coxa articulates at the ventral extremity of the pleural suture.

coxal sacs (ARTHRO: Diplopoda) Eversible thin-walled sacs in the coxae of the legs.

coxal stridulatory organ (ARTHRO: Insecta) In Hemiptera, longitudinal striations of the coxal base and the cephalic margin of the lateral plate of the coxal cavity.

coxal stylets (ARTHRO: Insecta) The coxal epipodites.

coxal vesicle (ARTHRO: Insecta) In Collembola, the basal part of the ventral tube, believed to represent the fused coxae of the segmental appendages and the vesicles.

coxa rotatoria (ARTHRO: Insecta) A coxa with a monocondylic joint; having a single condyle.
