Ms. Gomez et al., OCCURRENCE OF INTERGRADES BETWEEN ODONTOPSYLLUS-QUIROSI-QUIROSI AND ODONTOPSYLLUS-QUIROSI-EPISCOPALIS (INSECTA, SIPHONAPTERA) ON NORTHEAST OF SPAIN, Parasite, 3(1), 1996, pp. 81-84
The detection of 4 males and 1 female of Odontopsyllus quirosi which c
onstitute intergrades between quirosi and episcopalis palaearctic subs
pecies are pointed out by the authors. The specimens were isolated fro
m rabbit burrow, in an area known as ''Retuerta de Pina'' located in t
he Monegros (province oi Zaragoza) on North-East oi Spain. The prospec
ted site could constitute one of the border limit points of sympatric
distribution area of both palaearctic subspecies.
