The Tobochares emarginatus species group can be recognized by the oblique and posteriorly directed anterior margin of the eye in lateral view, which emarginates the eye to about a quarter of its dorsal width (Fig. 2C ; Kohlenberg and Short 2017 : fig. 6C-F), the presence of a broad, ovoid to diamond-shaped glabrous patch on the metaventrite (Fig. 5F ), the dense and uniform distribution of the hydrofuge pubescence on the abdominal ventrites (Fig. 5F ), and the moderate (in number and size) metatibial spines.
