text: Hünicken wrongly identified the specimen as a mygalomorph spider based on the shape of the carapace, the 15 millimetres (0.59 in) wide circular eye tubercle located between the two eyes in the center of the head, a structure in front of the carapace he identified as spatulate chelicerae, and a circular structure behind the first body segment which he identified as the "moderately hairy" abdomen.
