摘要

用扫描电子显微镜研究了俄罗斯南乌拉尔Pismenka河中两个新种棘囊虫Acanthocystis lyra sp. 11和A. siemensmae sp. 11。这些种的细胞有长和短的脊鳞，具有中空的轴和圆形的基板。A. lyra的长脊鳞分为两个弯曲的s形分支，其内表面有小齿。短棘鳞有初级和次级分叉。每个次级分枝的末端都有两个齿。A. siemensmae既有长鳞，也有短鳞，尖呈漏斗状，尖上有小齿。根据Mikrjukov, 1997提出的分类方法，A. lyra被归为A. turfacea种群，A. siemensmae被归为A. pectinata种群。讨论了该新种与棘囊藻属其他成员的异同。

New freshwater species of centrohelids Acanthocystis lyra sp. nov. and Acanthocystis siemensmae sp. nov. (Haptista, Heliozoa, Centrohelea) from the South Urals, Russia

Two new species of centrohelids Acanthocystis lyra sp. nov. and A. siemensmae sp. nov. from the Pismenka River in the South Urals, Russia, have been studied with scanning electron microscopy. Cells of these species have both long and short spine scales with hollow shafts and circular basal plates. A. lyra has the long spine scales divided into two curved S-shaped branches possessing small teeth on their inner surface. The short spine scales have primary and secondary bifurcations. Every secondary branch ends with two teeth. A. siemensmae has both long and short scales with funnel-like apices, which possess small teeth. Based on the scale morphology A. lyra has been attributed to the A. turfacea species group, whereas A. siemensmae has been attributed to the A. pectinata species group, both according to classification proposed by Mikrjukov, 1997. Similarities and differences of the new species with other members of the genus Acanthocystis have been discussed.
