Abstract
REFERENCE has often been made1–3 to the colour varieties of Theridion ovatum. According to Locket and Millidge4, the abdomen may have one of three colour patterns: Clerk's lineatum, abdomen creamy white; Clerk's redimitum, abdomen with a pair of wide longitudinal carmine stripes; Clerk's ovatum, abdomen dorsally covered with carmine. Field observations confirm that these varieties are polymorphic, in accordance with the accepted definition5 for genetic polymorphism.
