TABLE 2. Meristic and morphometric data on the type series and additional material (AM) (six specimens examined) of Notarius insculptus. For paralectotypes and AM counts, figures between brackets indicate number of specimens with each count (some data are missing). Lectotype measurements are presented in millimeters, and percents of the standard length appear between brackets. Paralectotypes and AM measurements are given as a range; total lengths and standard lengths are expressed in millimeters, the additional measurements are presented as percents of the standard length. | Lectotype | Paralectotypes and AM |
