Rotifer samples were obtained from 29 localities in northern Guatemala and central-southern Belize during March 2000 and June 2001. A total of 119 species were identified. Ten selected taxa are illustrated and commented: Euchlanis semicarinata, Lepadella apsicora, L. cryphaea, Lecane curvicornis f. lofuana, L. whitfordi, Monommata maculata, Scaridium bostjani, Trichocerca elongata f. braziliensis, and Z. hollaerti. The species Lepadella rhomboidula is a first record for the American Continent. The species are 71% cosmopolitan, 6 % tropicopolitan, and 4.2 % restricted to the subtropics. The Guatemala species number range was Petén-Itza lake (53 taxa), and Raxruja pool (three). La Democracia pool (49 taxa), and the Blue Hole sink-hole (six species) were the extremes in Belize. In total, 68 of the recorded taxa are new for Guatemala and 91 for Belize. Additionally, 47 species are registered by the first time in Central America. A comparison between these two countries and Mexico revealed that the south part of the latter conform a cluster with them, emphasizing the transitional character of this region between the Nearctics and the Neotropics. Furthermore, Guatemala and Belize have differences in species assemblages, as a response to the nature of their particular environments and topographical accidents.
2000年3月至2001年6月期间，从危地马拉北部和伯利兹中南部的29个地点采集了轮虫样本。共鉴定出119个物种。对十个选定的分类群进行了图示和注释：半脊真藓虫、隐角叶蚤、隐蚤、弯角列蚤f. 洛富纳蚤、惠特福德列蚤、黄斑单蚤、博斯贾尼裂蚤、细长三肢轮虫f. 巴西三肢轮虫和霍拉尔蒂泽蚤。菱形叶蚤是美洲大陆的首次记录。这些物种中71%为世界性分布，6%为热带世界性分布，4.2%局限于亚热带地区。危地马拉的物种数量范围为佩滕 - 伊察湖（53个分类群）和拉克鲁哈池（3个）。在伯利兹，拉民主池（49个分类群）和蓝洞沉洞（6个物种）为极端情况。记录的分类群中，共有68个对危地马拉来说是新物种，91个对伯利兹来说是新物种。此外，47个物种首次在中美洲被记录。这两个国家与墨西哥之间的比较表明，墨西哥南部与它们形成一个集群，强调了该地区在新北界和新热带界之间的过渡特征。此外，危地马拉和伯利兹在物种组合上存在差异，这是对其特定环境性质和地形意外情况的一种响应。
