Thelaziidae is a family of spirurian nematodes, which form the mid-sized lineage of the superfamily Thelazioidea. Like all nematodes, they have neither a circulatory nor a respiratory system. They number 7 genera or so, with a few dozen species altogether. Mostly parasites birds, a few have also been found in other vertebrates.〔Hallan (2007)〕 ==Systematics== The subfamily Oxyspirurinae is monotypic, as are several little-known genera in the Thelaziinae; these all might not be valid. Altogether, the systematic layout of this family is liable to change and cannot be considered more than tentative.〔 Subfamily Oxyspirurinae Skrjabin, 1916 * ''Oxyspirura'' Dräsche in Stossich, 1897 Subfamily Thelaziinae Skrjabin, 1915 * ''Ceratospira'' Schneider, 1866 * ''Hempelia'' Vaz, 1937 * ''Pancreatonema'' McVicar & Gibson, 1975 * ''Pericyema'' Railliet, 1925 * ''Thelazia'' Bosc in Blainville, 1819 * ''Thylaconema'' Chandler, 1929 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thelaziidae is a family of spirurian nematodes, which form the mid-sized lineage of the superfamily Thelazioidea.
