Leiobunum aldrichi

Appearance

A small-bodied Leiobunum. Males are reddish brown (golden-yellow according to Davis, 1934), with or without darker markings; females vary from brown to orange but have a dark central figure on the abdomen as well as segmental bands of light spots. Both sexes have pale pedal coxae that contrast with the dark trochanters. The legs are generally dark brown or blackish but the second legs have a distinctive pale band at the distal end of the tibia. Palps are yellowish and the eye tubercle is black. The undersides are constrastingly whitish. The end of the abdomen in males is rounded or subtruncate rather than pointed. Total Length: 3–4 mm, males; 4.5–6 mm, females.
