Table 4. Measurements (in µm) of selected morphological structures of juveniles of Barbaria paucigranulata (type series) mounted in Hoyer’s medium. Abbreviations: N, number of specimens/structures measured; RANGE refers to the smallest and the largest structure among all measured specimens; SD, standard deviation; sp, the proportion of the length of a given structure to the length of the scapular plate| Character | N | RANGE | | | | | Mean | | SD | | Holotype | | Paratype 1 | | Paratype 2 | |
