Description

ABSTRACT. -- An investigation of the parthenogenetic Cnemidophorus laredoensis subgroup in the upper, middle, and lower Rio Grande Valley of Texas and Mexico between Giudad Acuna-Del Rio and the Gulf of Mexico has resulted in four significant new distributional records for clonal complex LAR-B and five for clonal complex LAR-A. The new data support the view that LAR-B is limited to habitats situated within 10 kilometers of the Rio Grande in the upper and lower parts of the valley and that the clonal complex is absent in all except the southern part of the middle valley. Newly collected specimens in northern Webb County establish the presence of LAR-A in the upper valley and significantly change our previous zoogeographic conception of this clonal complex. LAR-A also is reported for the first time in areas well removed from the river in parts of the the middle and lower valley. The loss of habitat at four sites indicates that previous statements pertaining to the survival of the LAR clones outside areas under state or federal protection may have been overly optimistic. Key words: distribution; habitats; parthenogenetic Cnemidophorus. **********
