The following species of phytophagus mites from the Southeast are of considerable economic importance and are herein described for the first time. Tenuipalpus bioculatus sp. nov. Female . Body crimson, with two rather well-defined eye-like spots on cephalothorax. Widest at posterior corners of cephalothorax, two-thirds as wide as long. The cephalothorax is narrowed considerably anteriorly, and the abdomen tapers to a rounded tip. The body is armed with a pair of weak spines on the anterior body margin medially, similar spines immediately before and behind the emarginate eyes, six at the posterior tip of the abdomen, a few along the body margin, and scattered ones dorsally. The cephalothorax is hardly half as long as broad, with the anterior margin convex; the palpi greatly resembles the Tetranychus type, the penultimate joint bears a strong claw, and the terminal joint (thumb) bears a “finger”. The legs are relatively stout, crenulated; forelegs in length three-quarters the width of cephal-othorax; four anterior tarsi blood-red in life; all legs bearing several lateral hairs, and a terminal bristle in length equalling the three distal segments; the trochanter of the four anterior legs with a lamellate hair placed dorsally; the tarsi with several terminal appendages including a pair of closely appressed claws, a very long bristle, and the four capitate hairs, so frequently seen in Tetranychus .
