B10287DEFF99B056FE6DFCECFB49F8CD.taxon	discussion	DISCUSSION: In both subspecies, distinct pits are visible only on the internal mold of the anterior border furrow (fig. 2 E, F). In this case (where the pit is not expressed on the dorsal surface), this trait may be better described as a series of “ protuberances ” on the ventral surface that form pits on the internal mold. These protuberances meet nodes on the doublure of the librigena beneath the anterior border of the cranidium (see Fortey, 1974: pl. 5, fig. 10). On other Balnibarbi species, the structures are visible on the anterior border (e. g., Balnibarbi pulvurea, see Fortey, 1974: pl. 1, fig. 4), and more in keeping with the idea of a “ pit. ” The holotype of Balnibarbi erugata erugata is almost completely exfoliated (fig. 2 A), but specimens that otherwise fit the diagnosis (including some listed by Fortey, 1974) show very fine granulation across the glabella (fig. 2 D), in the posterior border furrow (fig. 2 C), and more rarely preserved on the frontal area (fig. 2 B). Terrace lines are evident on the border of the holotype (fig. 2 A) and some better-preserved specimens (fig. 2 B). Fortey (1974) differentiated Balnibarbi erugata and Balnibarbi sombrero based on the length (sag.) of the preglabellar field relative to the glabella. The type and figured specimens of B. sombrero do have a larger preglabellar field (fig. 3), and there is no granulation visible on the external surface where preserved. However, some specimens that have fine granulation	en	Hopkins, Melanie J. (2019): Phylogenetic analysis and revision of the trilobite subfamily Balnibarbiinae (Olenidae).

B10287DEFF97B058FE6EFD09FCE2F934.taxon	discussion	DISCUSSION: Fortey (1974) distinguished Cloacaspis ceryx ceryx and Cloacaspis ceryx anataphra by the latter having a shorter (sag.) preglabellar field relative to the glabella, no visible pits in the anterior border furrow, and a smooth exoskeletal surface. Examination of new and old specimens suggests that the mean preglabellar / glabella ratio is on average shorter in C. ceryx anataphra, but there is overlap in variation in this variable. In addition, while pits are not visible in the anterior border furrow, they are present and visible on the internal mold (fig. 4 B, C). On the few specimens where it was possible to estimate the number of anterior pits, the number is slightly smaller (25 – 30) compared to C. ceryx ceryx (> 30). Although granulation is very fine on C. ceryx ceryx and its preservation is very sensitive to any erosion of the surface (fig. 4 D – F), it does appear that some specimens truly lack surface granulation. Based on this evidence, the two taxa are retained as subspecies, but the species complex is reassigned to the genus Cloacaspis based on the results of the phylogenetic analysis. The species complex is united with other Cloacaspis species by having advanced genal spines (char. 34), relatively large palpebral lobes (char. 19), and forward curvature of the palpebral lobe (char. 20). However, Cloacaspis ceryx shares some characters with some Balnibarbi species, including greater divergence of the anterior dorsal suture (char. 9), relatively wide palpebral lobes (char. 21), relatively short 3 P (char. 25) larger number of axial rings (char. 37), and medial indent on posterior margin of pygidium (char. 44). The latter three characters are also shared with Cloacaspis dejecta.	en	Hopkins, Melanie J. (2019): Phylogenetic analysis and revision of the trilobite subfamily Balnibarbiinae (Olenidae).
