Two new phreatic snails (Mollusca: Caenogastropoda: Cochliopidae) from the Edwards and Edwards-Trinity aquifers, Texas
<p>The Edwards and Edwards-Trinity Aquifers of Texas have diverse stygofauna, including fifteen species of snails found in phreatic and hyporheic habitats. These species have the hallmarks of adaptation to subterranean environments including extremely small body size and the loss of pigmentation and eyes. Here we use an integrative taxonomic approach, using shell, radula, and anatomical features as well as mitochondrial and nuclear DNA data, to circumscribe a new genus and two new cavesnail species from Central Texas. <em>Vitropyrgus</em> <em>lillianae</em> gen. et sp. nov. is described from Comal Springs (Comal County) and Fessenden Springs (Kerr County) and distinguished by a glassy, highly sculptured shell and distinctively simple, unornamented penial morphology. We also describe<em> Phreatodrobia bulla </em>sp. nov. from Hidden Springs (Bell County), and several other springs in Bell & Williamson Counties, Texas. This species has a smooth, unsculptured teleoconch, a reflected and flared lip, and deeply concave operculum. </p>

Figure 5 - Plot of δ15N on δ13C values for the stygobiont Palaemonetes antrorum (PS, red oval and black oval respectively excluding and including two outliers, see text) and the epigean Palaemonetes kadiakensis (PE, small blue oval). The range of values of δ13C derived from different energy sources (see text) is indicated (methane, and photosynthesis from C3 and C4 plants) as well as values typical of marine carbonates and petroleum. The diagonal dotted line denotes a typical trajectory (not the value) of amplification of δ15N values with progression through trophic levels (Vanderklift and Ponsard 2003).
