Eucolpocephalum femorale ( Piaget, 1880)

( Figs 1c,d ; 2c )

Specimens examined. 1♂ ( SEHU #74901 , # 94203 ) and 2♀ ( SEHU #94204 , # 94208 ) each mounted on a slide ; 2♂ and 8♀ stored in alcohol ( SEHU) .

Diagnosis. The monotypic genus Eucolpocephalum can be diagnosed by the following combination of characters: Head short and broad; preantennal region with 3 long and 3 short setae on each side; temple broad transversely, with 6–7 long and 2–4 short setae. Male genitalia: parameres elongated and curved inwardly, with complex median sclerites as in Fig. 2c .

Remarks. The identification of E. femorale was based on the descriptions of Piaget (1880) for general morphology, Bedford (1930: 162, fig. 6) for head morphology, and Tuff (1966: 380) for chaetotaxy and the morphology of male genitalia. This species has been recorded from four spoonbill species and one ibis, as follows: Platalea leucorodia Linnaeus, 1758 , Platalea ajaja ( Linnaeus, 1758) , Platalea alba Scopoli, 1786 , Platalea regia Gould, 1838 and Phimosus infuscatus berlepschi Hellmayr, 1903 , the bare-faced ibis ( Price et al. 2003: 108). Ledger (1971: 98) suggested that the record of a male and female pair of E. femorale from the bare-faced ibis in Tuff (1966: 382) was probably erroneous and in need of confirmation. Our sample of E. femorale from Platalea minor is the first record from this host.
