-shape, and with two long thin setae and two short thin setae emanating from a deep section of the structure (Figs 2B, 3C). Large tegulum above subtegulum that extends out past subtegulum. Embolus within embolic membrane curves around in full 360° loop near anterior end of cymbium. Suprategular apophysis projects anteriorly within the center of the embolic loop. Ventral and medial processes project anteriorly from embolic division (Fig. 3).

<paragraph id="8618FF878C0F4107AAABD2DAC839B63B" pageId="4" pageNumber="23">Stygian River Cave is short and consists of a room filled with large, wet, muddy rocks and boulders. Because of the short length of the cave, the biota is likely heavily influenced by low winter humidity. The cave sits at the confluence of the Blue and Ohio rivers and at least part of the cave is regularly underwater when these rivers rise. These specimens were largely found in webs in between the large boulders within the largest room of the cave. The type locality was only visited once and were therefore only collected once, on October 23rd, 2016.</paragraph>
