Material examined

3 ♂♂, 6 ♀♀, St. 10, leg. S. Taiti and C. Rossano, 26 April 2004 ( MZUF 9524 ) .

Remarks

These specimens are identified as P. flavocinctus after comparison with the redescription of this species provided by Arcangeli (1936, p. 190, Figures 1–7 ). The main characters of the specimens from the Oued Laou valley are here illustrated ( Figures 28 and 29 ) and they fit well those of P. flavocinctus provided by Arcangeli. The record of Budde-Lund (1885) from El Araisch (= Larache) in northern Morocco was considered doubtful by Arcangeli (1936). Our record from the Oued Laou valley together with those by Vandel (1958a) from the Rif confirms that this species is also present in this part of north-western Africa.

Previous Rif records

Melilla; Mt Gurugu and Ixmoart, near Melilla; Sidi Yacoub el Basi, near Peñón de Velez, Tétouan; Benitez, near Ceuta ( Vandel 1958a).

Distribution

Southern Spain, southern Portugal and northern Morocco.
