Ibidoecus plataleae ( Denny, 1842)

( Figs 1a,b ; 2a )

Specimens examined. 1♂ ( SEHU #94201 ) and 1♀ ( SEHU #94202 ) mounted on a slide; 2♂ and 5♀ stored in al- cohol ( SEHU) .

Diagnosis. Ibidoecus plataleae can be distinguished from its congeners by the following combination of characters: Head: anterior dorsal plates and preantennal region short. Thorax: 17 posterodorsal marginal setae on each side in males, 19 in females, extended to midline of divided pteronotum. Abdomen: male tergite XI heavily sclerotized and semicircular in shape ( Fig. 2a ); female with inner margin of each lateral sternal plates on segment VII joined to the central portion of the genital plate. Male genitalia as in Fig. 2a ; female genitalia as in Fig. 1b .

Remarks. T he identification of I. plataleae was based on the descriptions of Martín-Mateo (1994: 114) and Tandan (1958: 406) for general morphology, and the figures of male and female genitalia in Tandan (1958: 407, figs 23, 26). Ibidoecus plataleae has been recorded from Platalea leucorodia and P. regia ( Price et al. 2003: 192) . Our sample of I. plataleae from P. minor is the first record from this host.
