在采集于哥斯达黎加的苔藓标本中，发现63个标本和13个卵，其中假中生藓属Mesobiotuspseudopatienssp. nov.属于harmsobiensis组，与中生藓属Mesobiotuspatiens最相似，但主要区别在于卵较小，卵突较长，具弹性，成虫的某些形态特征。此外，在对采集于哥斯达黎加的Milnesium属标本进行重新检查后，哥斯达黎加动物群中可能增加了一个新记录种Milnesium kogui。本文还讨论了哥斯达黎加缓步动物的分类学问题和动物地理学，部分符合大美洲生物交流和墨西哥过渡带的假说。大量的所谓的“哥斯达黎加物种”是可疑的类群与“世界性”的分布;最大数量的物种，然而，有热带/亚热带或新热带分布。来自寒冷地区的某些物种也出现在哥斯达黎加的山区。http://zoobank.org/urn:lsid:zoobank.org:pub:F6F6195E-0888-4279-A3AF-422642F8B40
ABSTRACT In a moss sample collected in Costa Rica, 63 specimens and 13 eggs of the new species were found. Mesobiotus pseudopatiens sp. nov. belongs to the harmsworthi group and is most similar to Mesobiotus patiens, but it differs from it mainly by smaller eggs, longer flexible portions of egg processes and certain morphometric characters of adults. In addition, after re-examination of specimens of the genus Milnesium collected in Costa Rica, a new record of Milnesium kogui may be added to Costa Rican fauna. The paper also discusses taxonomical problems and the zoogeography of Costa Rican tardigrades, which partially agree with hypotheses of Great American Biotic Interchange and Mexican Transition Zone. A large number of so-called ‘Costa Rican species’ are doubtful taxa with ‘cosmopolitan’ distribution; the largest number of species, however, have tropical/subtropical or neotropical distribution. Certain species from colder regions are also present in the mountains of Costa Rica. http://zoobank.org/urn:lsid:zoobank.org:pub:F6F6195E-0888-4279-A3AF-422642F8B40
