Remarks. Newportia stolli is exclusively epigean and was cited from Guatemala and Colombia ( Bücherl, 1959) before it was reported from Mexico. Schileyko & Minelli (1999) did not state what their general record was based on nor mention a region of Campeche, but we confirm occurrence in the state with the two samples from Xpuhil. To our knowledge, these are the first definite records of the Scolopendromorpha from the Yucatan peninsula.

The southernmost generic representative in Mexico, N. stolli occupies two disjunct areas, a band that extends widthwise across the country from the Pacific Coast in Chiapas for an unknown distance in the Yucatan, and a site some 200 mi (320 km) to the northeast in Veracruz ( Fig. 17 ). At present, the southern records are detached from the other species, but we suspect this reflects inadequate sampling in the Isthmus of Tehuantepec (Tabasco, eastern Veracruz and Oaxaca, and western Chiapas). While sympatric species may occur in eastern and southern Chiapas, a substantial amount of sampling has taken place there, to the point that we think other representatives would have been encountered by now if they existed .

Figures

FIGURE 17. Occurrences of species of Newportia in Mexico; some symbols represent more than one locality. Star in dot, N. troglobia; open star, N. sabina; upright triangles, N. stolli; open square, N. spinipes; dots, N. oreina; solid square, N. pelaezi; circles, N. atoyaca; inverted triangles, N. morela. The asterisk marks the location of Córdoba, Veracruz, the type locality of both N. mexicana and N. azteca; the question mark indicates the unspecified “co­type locality” of N. oreina from Guerrero, which we consider questionable. The solid star denotes the type and only known locality of Ectonocryptops kraepelini.
