Table 7 (continued). Measurements (in μm) and pt values of selected morphological structures of hatchlings of Richtersius ingemari sp. nov. Specimens mounted in Hoyer’s medium. Range refers to the smallest and the largest structure among all measured specimens. Abbreviations: N = number of specimens/structures measured; SD = standard deviation. * when N = 1, the mean is the measurement.

表7（续）。里奇泰属（Richtersius）新种Richtersius ingemari sp. nov.初孵幼体的选定形态结构测量值（单位：μm，微米）与pt值。标本采用霍伊尔封固剂（Hoyer’s medium）封片。测量范围指所有被测样本中对应结构的最小与最大测量值。缩写说明：N为被测样本/结构的数量；SD为标准差（standard deviation）。* 当N=1时，平均值即为单次测量值。
