The Dolloff cave spider (Meta dolloff) is the largest web-building spider to occur within the Santa Cruz Caves in the United States (2). The body of this species is mostly brown, with indistinct barring on its legs. There are two dark patches on the top of the abdomen, with two light triangular markings between them, and the back of the abdomen is marked with dark, horizontal bars. The sides of the body are streaked. The measurement of the length and height of the abdomen of Meta species is roughly equal, and is narrower towards the head and widest at the centre. In this genus the first pair of legs is the longest and the third pair is the shortest. The underside of the abdomen of the Dolloff cave spider is grey and has two parallel white lines made up of tiny spots (3).
The head region of the Dolloff cave spider is narrow and has very strong mouthparts and closely-spaced eyes, which are present in all members of this genus (3).
The female Dolloff cave spider is slightly larger than the male. Males of the genus Meta generally have more curved mouthparts than the female (3).
