Dermacentor Anocentor nitens Neumann Description Larvae 0. Dimensions among male ticks range mm L by 1. Males are inornate and appear yellowish-brown in color. Females range mm long and 1. The scutum of female ticks is brownish yellow in color, somewhat longer than wide, has no discernable pattern, but appears quite glossy upon inspection. Distribution The range of the tropical horse tick in the US is limited to southern regions of Texas and Florida.

Abstract Distribution and host data from published literature and previously unpublished collection records are provided for all nine species of the Holarctic tick genus Dermacentor that are known to occur in Mexico, as well as two species that may occur there. Parasite-host and host-parasite lists are presented, together with a gazetteer of collection localities and their geographical coordinates.
Keywords: Dermacentor, ticks, hosts, distribution, Mexico Introduction The genus Dermacentor Koch, is a largely Holarctic group of ticks that may be characterized as follows: eyes and festoons present, basis capituli sub-rectangular, palps short and thick, and scutum usually ornate.
Most species are three-host parasites of mammals, although two Mexican species, Dermacentor albipictus Packard and Dermacentor nitens Neumann, are one-host ticks.
Adults of three-host species usually feed on medium-sized to large mammals, whereas immatures feed on small mammals. This group includes species that are important vectors of microorganisms causing disease in humans and domestic and wild animals Cooley , Yunker et al. Collection records for Mexican Dermacentor species date to the first half of the 20th century.
The presence or absence of both Dermacentor andersoni and Dermacentor latus in Mexico will have to be determined before our inventory of Mexican Dermacentor can be considered complete. This work is divided into four sections. The first section is a parasite-host list organized alphabetically by tick species and Mexican state. Published tick collection records are presented in the following order: state capitalized and in boldface , collection locality, host species, and reference s.
The second section is a host-parasite list, where hosts and their respective parasites are presented in alphabetical order. Mammalian names have been updated to accord with those of Wilson and Reeder and Ceballos The third section is a gazetteer of collection localities and their geographical coordinates. Where coordinates are not available for a specific locality, we reference the coordinates for the nearest municipality.
The last section is a map, constructed using the program ArcGIS 9.
