摘　　要：对虎纹捕岛蛛 (Ornithoctonushuwena)的眼、生殖球、颚叶、听毛、触毛、琴形器、跗节器、发音器。Ornithoctonus huwena , a burrow dwelling spider found in southern of China, is one of China's largest spiders. This paper deals with fine structures on the body surface of Ornithoctonus huwena. Spinneret, eye, chelicerae, genital bulb, maxillae, trichobothrium, hairs, lyriform organ,tarsal organ and stridulating organ structure were studied using scanning electron microscopy. The results suggest that this spider has two pair of spinnerets, the total length of the anterior spinneret is 3 1?mm, the total length of posterior spinneret is 8 2?mm and 8 ocelli, anterior lateral eye>posterior lateral eye>anterior median eye>posterior median eye. This spider hears have very tiny hairs on its legs (thrichobotria); it is capable of localizing the origin of a sound by interpreting the movement of the air produced by that sound. Odours are detected with a scent sensitive tarsal or lyriform organ located on the legs, this species feels prey with chemosensitive hairs on its legs thus sensing if the prey is consumable.
