volume, of which 61 Texas species are believed tobe troglobites and another 16 are Texas troglophiles.An additional nine troglobites (1 each from Alabama,Arizona, and New Mexico and 6 from Mexico)are also described.The present volume includes only a few of thegroups known to contain undescribed species inTexas caves. It is hoped that a future volume can bepublished covering additional families and orders,including millipedes, terrestrial isopods, entotrophs,and cave crickets.Many of the species in this volume occur in areasundergoing rapid urbanization and may be listed asendangered in the future. Of species treated herein,four (two species of Texella, Texamaurops reddelli,and one species of Batrisodes) are considered asendangered by the U.S. Fish & Wildlife Service.Many of the caves from which fauna has beenrecorded have already been destroyed; others,including some of considerable biological importance,are seriously threatened. It is one of the goalsof the present volume to make available to conservationistssufficient taxonomic and distributional informationas to allow a determination to be made onthe necessity of protecting species by their placementon the U.S. Fish & Wildlife Service List ofEndangered Species.My greatest debt of gratitude is to Dr. WilliamR. Elliott for his invaluable contributions to thepreparation of this book for the printer. His encouragementand friendship not only during preparationof this book but for many years have been aninspiration to me in my own work.I wish to express my particular appreciation tothe authors of the papers for their cooperation,especially where newly obtained material requiredrevisions of the original manuscripts. I speciallythank William R. Elliott, Andrew Grubbs, ScottHarden, David McKenzie, Marcelino Reyes,William Russell, and George Veni for theircollecting efforts for many years. Without theircooperation and friendship we would know far lessabout the cave biology of Texas than we do. Dr.Robert W. Mitchell is thanked for his inspiration tome both as a friend and student; he has alwaysprovided whatever support was asked. Dr. Mitchellis also thanked for contributing the photograph onthe cover of this volume.vi
