ASPIDOSCELIS AT TWO FORT SUMNER SITES

The first specimen of A. neomexicana reported from the Pecos River drainage in De Baca County was collected on 9 June 2002 at FS­1, Fort Sumner­De Baca County Landfill (table 1; fig. 7; appendix 6) in the suburbs of Fort Sumner ( Taylor, 2002). Subsequently, in three visits to FS­ 1 in 2002 and 2003, a site consisting of frequently altered patches of roadside weeds, mounds of earth, and debris ( fig. 7), GJM found syntopic associations of A. neomexicana , A. sexlineata viridis , and A. tesselata E. Both E. D. Parker (personal commun.) and JMW collected and observed only A. sexlineata viridis and A. tesselata E at FS­ 1 in 1973 and 1996–1998, respectively.

At FS­2, Fort Sumner­Railroad Depot, consisting of the railroad right­of­way and a bordering mesquite association ( fig. 7), GJM found a large number of A. neomexicana including AMNH R­151741 used in karyotypic and electrophoretic analyses (appendix 7). In five visits to the Fort Sumner­Railroad Depot in 2002 and 2003, he observed syntopic associations of A. neomexicana , A. sexlineata viridis , and A. tesselata E.
