138 Volume 19, No. 3, September, 2005, INSECTA MUNDIA male of a neotropical jumping spider, Phidip-pus bidentatus F. O. P.-Cambridge 1901, was col-lected by John Scott Armstrong and his staff froma boll weevil trap in Cameron County, Texas. Therecent revision of the genus Phidippus (Edwards2004) gave the range of this species as centralMexico to northwest Costa Rica. In addition, thespecimen has a character, namely the presence of adistinct cheliceral distal dorsal tubercle, that wouldmake it key out in the second couplet of the key,along with Phidippus audax (Hentz) and P. regiusC. L. Koch. However the structure of the malepalpus is quite different than either of the latterspecies (Edwards 2004, Figures 153, 236 and 242).The data for this adult male are:USA: Texas: Cameron County, Russell Plantationnear San Benito, 97.550262ºW 26.0836625ºN, froma boll weevil trap on the turn-row between sugar-cane and a rasaca (irrigation ditch from Rio Grande),9 March 2004. This site is over 400 mi. north of theprevious northernmost record in the State of Ver-acruz, Mexico.The surrounding area is covered with grass andlow herbaceous plants with nearby small trees anda nearby dead tree. For predominant plants in thearea, see Table 1. The locality makes it unlikelythat it was accidentally introduced.This spider, with its iridescent pink centralabdominal stripe, covering of iridescent pink andgreen scales, and bi-colored brown and iridescentblue chelicerae, is an attractive addition to thefauna of the United States.We would like to thank Scott Armstrong andhis crew, as well as the owners of the RussellPlantation, Frank and James Russell, for the op-portunity to see this interesting specimen. Thespecimen is deposited in the Florida State Collec-tion of Arthropods, Gainesville, FL.References citedCambridge, F. O. P. 1901.
