Comments: Typhlacontias johnsonii is found in Angola and Namibia , with a distribution restricted to the Namib Desert ( Haacke 1997 ; Marques et al. 2018 ). Ferreira (1904 , 1906 ) did not cite these specimens. Haacke (1997) reviewed the genus Typhlacontias , providing descriptions, distributional records and a key to the genus. This species was originally described based on six specimens , of which Haacke (1997) designated the largest and first mentioned specimen as a lectotype and the remaining as paralectotypes . The author also corrected Bocage’s (1895) identification of a Typhlacontias punctatissumus from “Coroca” to T. johnsonii ( Haacke 1997 , Marques et al. 2018 ). T. johnsonii is characterized by the presence of a subhexagonal to oval shaped frontal shield and the second upper labial scale reaching the eye ( Haacke 1997 ).
