Six-ocellus model with four accessory ocelli, indicated in black (A), and nine general patterns with fewer than six ocelli (B–J), indicating most common positions and relative sizes (AALMa PLMa> PDMi>ADMi; PDMi> PLMi; PLMi> APLMi₁; PLMi  =  APLMi₂; PLMi> APLMi₃) of lateral ocelli in Recent scorpions.

<p><b>B.</b> Type 5, shaded areas represent positional variation in ADMi and PDMi. <b>C.</b> Type 4A. <b>D.</b> Type 4B. <b>E.</b> Type 4C. <b>F.</b> Type 3A. <b>G.</b> Type 3B. <b>H.</b> Type 2A. <b>I.</b> Type 2B. <b>J.</b> Type 1. Abbreviations: accessory anterolateral major ocellus (AALMa); anterolateral major ocellus (ALMa); mediolateral major ocellus (MLMa); posterolateral major ocellus (PLMa); posterolateral minor ocellus (PLMi); posterodorsal minor ocellus (PDMi); anterodorsal minor ocellus (ADMi); three accessory posterolateral minor ocelli (APLMi₁, APLMi₂, APLMi₃).
