.--Gorgan, Golestan Province, Iran (Zacheus hyrcanus); Lahidjan, Gilan Province, Iran (Platybunus pusillus); Tehran, Tehran Province, Iran (Metadasylobus dentichelis).
Maps were created by plotting the traces of the seaway from various times in the Cretaceous and plotting the type localities
for the same times on the Tapestry map, which showed areas that have been heavily sampled.
Despite the high number of species within the genus, most type localities
are well defined mainly thanks to the work of the eminent taxonomist Oldfield Thomas who described 27 species and 8 subspecies of tucotucos today accepted as valid (Hill, 1990; Bidau, 2006, 2009).
Distribution.--Known only from the type localities
The title, although unwieldy, says it all: this book offers extremely thorough accounts of all mineral species whose type localities
lie in Switzerland--there are 64 of these--and just-as-detailed accounts of another 23 species which were named after Swiss citizens, though their type localities
lie in other countries.
The genus Asiotmethis should be revised, using not only museum material, but also new material to be collected from the type localities
and the other distributional areas.
These include type localities
of many fossil species.
Additional collecting in both type localities
brought to light males of these species.
Future analysis of specimens from type localities
as well as of type specimens and broad sampling across the geographic range of the genus, are needed to solve the taxonomy of the group.
Italy holds the fourth position in terms of type localities
for species recognized by the International Mineralogical Association, with about 240 mineral species.
Britvin, reviewing "The history of mineral discoveries," found that the United States contains the type localities
for the most species (637), followed by the former Soviet Union (573, of which 448 came from Russia), Germany (255), Italy (203), Canada (167), Sweden (162), Australia (109), France (104), Zaire (93), Mexico (83), China (76), Chile (71), Namibia (68), Greenland (65) and Norway (56).
Franklin and Sterling Hill, the type localities
for no less than 69 mineral species, rank unquestionably among the world's most extraordinary and fascinating mineralized areas.
