Eminoculus Schuh is revised and an updated diagnosis is presented for the genus. Seven species are recognized, five of which are described as new. Diagnoses, digital habitus photographs, illustrations of male and female genitalic structures, keys to both the males and females, and detailed locality are provided. Scanning micrographs of diagnostic morphological structures—the head, pronotum, scent-gland evaporatory area, vestiture, and pretarsus—are included for four species. A phylogenetic analysis is presented, using the South African species Lasiolabopella capeneri Schuh and the Nearctic Chlamydatus keltoni Schuh and Schwartz as outgroups. Host data are presented for 6 species, and patterns of host association with the “mesem” clade of the Aizoaceae are discussed.
