Fessisentis tichiganensis sp. nov. is described on the basis of 16 male and 24 female worms recovered from 11 species of fish of seven families in Tichigan Lake, southeastern Wisconsin, between 1977 and 1979. Specimens were most frequently encountered during the spring; the only two gravid females were recovered from Umbra limi, in early June. The same fish also serves as a transport host. A key separating F. tichiganensis from the four other known species in North America is presented. The new species most closely resembles F. friedi Nickol 1972 (= F. vancleavei haley and Bullock 1953), but can be separated from it by its longer proboscis which is armed with markedly more hooks per row, among other characteristics. Additional, new morphological observations are also reported.
密歇根费西线虫新种（Fessisentis tichiganensis sp. nov.）是根据1977年至1979年间从威斯康星州东南部密歇根湖7个科的11种鱼类中采集到的16条雄虫和24条雌虫描述的。标本在春季最为常见；仅有的两条怀卵雌虫于6月初从泥狗鱼（Umbra limi）中采集到。同一种鱼也作为转运宿主。本文提供了一个将密歇根费西线虫与北美其他四种已知物种区分开来的检索表。新物种与1972年的弗里德费西线虫（F. friedi Nickol）（= 1953年的范克莱费西线虫（F. vancleavei haley and Bullock））最为相似，但在其他特征中，其吻部更长，每行的钩明显更多，可据此将二者区分开来。此外，还报告了新的形态学观察结果。
