ADDITIONAL DATA ON THE MORPHOLOGY, ANATOM Y AND POSSIBLE HOST-PARASITE INTERACTIONS OF PHACOPSYLLA-INEXPECTATA (SMIT, 1950) (INSECTA, SIPHONAPTERA, PULICIDE)

The description of Phacopsylla Beaucournu and Horak, 1994, has been su pplemented by various observations involving the cephalic capsule, cox a III, nervous system (not ventral in males), digestive tract and resp iratory system. The latter exhibits strange tracheal dilations, akin o nly to those found in Moeopsylla sjoestedti, the only other oioxenous flea of the warthog, by the authors. The authors note that the real na me of the host is Phacochoerus africanus (Gmelin); the biology of this suid could account for the specificity of these fleas, and possibly f or the tracheal dilations observed.
