Phylogenetic relationships among New World and eastern Atlantic species in the belonid genera Strongylura and Tylosurus were hypothesized using 3689bp of nucleotide sequence; including the entire mitochondrial (mtDNA) ATP synthase 6 and 8 genes; partial cytochrome b; 12S and 16S ribosomal genes; and introns and exons, 2 and 3 of the nuclear-encoded creatine kinase B gene. Concordant mtDNA and n...

Simultaneous multiple infestation of parasitic crustacean species involving a cymothoid isopod, Cymothoafrontalis Milne Edward, 1840 and four species of copepods such as Lernanthropustylosuri Richiardi, 1880, Caligodeslacinatus Kroyer, 1863, Bomolochusbellones Burmeister, 1833 and Dermoergasiluscoleus Cressey & Collette, 1970 was frequently noticed on spot-tail needlefish, Strongylurastrongylur...

Two new nematode species, Philometra strongylurae sp. n. and Philometra tylosuri sp. n., are described from female specimens collected from needlefishes (Belonidae, Beloniformes) off the Fao coast, Basrah, Persian Gulf, in Iraq. Philometra strongylurae (gravid females with larvae) was recorded from the subcutaneous tissue, muscles of beak and gills of Strongylura leiura (type host) and S. stron...
