Missing Information
In the original publication [1], the type species for Tectucantus gen. nov. was not assigned in the Results in Section 3.1.1, before paragraph 1. The assigned type species is T. tinnulus and should read as follows:
Type species: T. tinnulus sp. nov. here described.
Text Correction
There was an error in the original publication [1]. There is a Latin grammatical error in the species epithet for T. planatum.
A correction has been made to Sections 3.1.4, 3.2 and 3.2.3 of the Results, Section 4.1 of the Discussion; the accurate form should be T. planatus. This amendment should be consistently reflected throughout the text, as well as in the labeling and legends of the figures and tables included (Figures 1–7 and Tables 1 and 2).
Error in Figure/Table
In the original publication [1], there was a mistake in the legends for Figures 1–7 and Tables 1 and 2 as published. There is a Latin grammatical error in the species epithet for T. planatum, and the correct spelling should be T. planatus. The corrected legends, Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7, and Table 1 and Table 2 appear below.

Table 1.
Body measurements. All measurements are in mm. For paired features (e.g., legs), left/right features were reported, respectively. n.a. = not applicable, where the structure was not present to be measured (e.g., damaged, absent, or absent due to sex differences).
