title: Description of a New Genus and Species of Stygobiontic Diving Beetle,Psychopomporus felipiJean, Telles, and Miller (Coleoptera: Dytiscidae: Hydroporinae), from the Edwards-Trinity Aquifer System of Texas, USA.
abstract: Psychopomporus felipiJean, Telles, and Miller,new genusandnew species(Coleoptera: Dytiscidae), is described from San Felipe Springs, Val Verde County, Texas, USA, which emerges from the Edwards-Trinity aquifer system.Psychopomporus felipishows several features typical of subterranean diving beetles, such as depigmentation, compound eyes reduced, elytra fused, and flight wings absent.Psychopomporusdiffers from other hydroporine genera in having a broad elytral epipleuron, the prosternal process small and with a medial, strongly produced prominence, and the meso- and (to a lesser extent) protibia apically broadly expanded and medially distinctly curved. This is the fourth stygobiontic diving beetle described from the Edwards-Trinity aquifer system in south-central Texas, USA.
