Austromenopon transversum ( Denny, 1842 ) ; Price et al . 2003 : 93 . Type host: Rissa tridactyla (Linnaeus, 1758) —Black-legged kittiwake. Material examined (n = 47). Ex Larus argentatus Pontoppidan, 1763: 5 ♂, 11♀, 3N, Jazan Fish Market ( 16o54'12''N , 42o32'40''E ), 24 Nov. 2012 . Ex Larus armenicus Buturlin, 1934: 4 ♂, 6♀, 1N, Jazan Fish Market ( 16o54'9''N , 42o32'40''E ), 23 Nov. 2012 . Ex Larus michahellis Naumann, 1840: 4 ♂, 7♀, 6N, Jazan Coast ( 16o56'22''N , 42o32'35''E ), 12 Dec. 2013 . Remarks: Species of the genus Austromenopon are parasitic on members of three bird orders, including Charadriiformes ( Price et al. 2003 : 90) . The best available revision of the species from Charadriiformes is by Clay (1959) . Specimens of Austromenopon are usually found on body feathers and near the host skin. Austromenopon transversum ( Figs 3 b, 4b) is the species which parasitizes most species of gulls in different parts of the world ( Price et al. 2003 : 93). Some of our specimens were found with the abdomen full of host blood. This species is characterized by: a reduction of the epipharyngeal pestle and hypopharyngial sclerites; the marginal prothoracic seta long, which may exceed the thoracic segments; and very long mesothoracic seta. These are the first records of A. transversum from the Armenian ( Larus armenicus ) and the yellow-legged gulls ( Larus michahellis ).
