About Cyrtarachne inaequalis Thorell, 1895
The female Cyrtarachne inaequalis has a body length ranging from 8 to 13 mm. Its carapace is brownish, with a darker head region, and the sternum is pale yellow. The abdomen of the female narrows toward the posterior, and is wider than it is long. The upper surface of the abdomen is yellowish, with two raised "shoulders" marked by brownish or grayish rings. The lower abdominal surface is yellow, with a dark brown median spot. The legs are yellow, and the scape is triangular with thickened edges and a scoop-shaped tip. The male Cyrtarachne inaequalis is much smaller, with a total body length of approximately 2 to 2.5 mm. The upper body surface of the male is generally darker than that of the female, except for the posterior section of the abdomen, which is yellowish brown. The male's sternum is lighter brown, and the underside of the abdomen is yellow with dark brown stripes. The median apophysis of the male's palpal bulb is thick and ends in a pointed tip.
