Iridomyrmex shandongicus is an extinct species of ant in the genus "Iridomyrmex".
 Described by Zhang in 1989, fossils were originally found in 1989, and out of all the fossils in the genus, this one has strongest support that it belongs in the genus.
Gasterellopsis is a fungal genus in the family Agaricaceae.
 This is a monotypic genus, containing the single species Gasterellopsis silvicola, originally found in East Lansing, Michigan.
 It is named for its similarity to the genus "Gasterella".
Redfield ratio or Redfield stoichiometry is the atomic ratio of carbon, nitrogen and phosphorus found in phytoplankton and throughout the deep oceans.
 This empirically developed stoichiometric ratio was originally found to be C:N:P = 106:16:1 (and has more recently been revised to 117:14:1).
 This term is named after the American oceanographer Alfred C. Redfield, who first described this ratio in an article written in 1934 (Redfield 1934).
 As a Harvard physiologist, Redfield participated in several voyages on board the research vessel Atlantis.
 Alfred Redfield analyzed thousands of samples of marine biomass across all of the ocean regions.
 From this research he found that globally the elemental composition of marine organic matter (dead and living) was remarkably constant across all of the regions.
 The stoichiometric ratios of carbon, nitrogen, phosphorus remain relatively consistent from both the coastal to open ocean regions.
Samsonia is a genus of Gram-negative bacteria in the family Enterobacteriaceae.
 Species within this genus were originally found in the bark of diseased Erythrina trees.
 Among bacterial plant pathogens within the Enterobacteriaceae, "Samsonia" species may be most closely related to "Pectobacterium" species.
 Up to now there is only one species of this genus known ("Samsonia erythrinae").
Arthrocereus is a genus of cactus, originating from southern Minas Gerais, Brazil.
Cardiaspina fiscella, the brown basket lerp or brown lace lerp, is a jumping plant louse species in the genus "Cardiaspina" originally found in Australia.
 It spread to New Zealand where it was found in 1996 near the Auckland airport.
 It feeds on eucalyptus, especially swamp mahogany, and is found in Victoria, eastern New South Wales, and southeastern Queensland, as well as the capital territory (ACT) around Canberra and on Norfolk Island.
 "Cardiaspina fiscella" has five nymphal instars, and as the instars moult they add a layer to their outside covering (casing), known as the "lerp".
Wardomyces is a genus of seven species of mould fungi in the family Microascaceae.
 The genus was circumscribed in 1923 by Frederick Tom Brooks and Clifford Gerald Hansford.
 The generic name honours Harry Marshall Ward, Professor of Botany at Cambridge University.
 The type species, "Wardomyces anomalus", was originally found as a mould growing on rabbit meat kept in cold storage.
 The most recent addition to the genus is "W. moseri", described by Walter Gams in 1995.
 Found in Colombia, it was discovered growing on a dead petiole of moriche palm ("Mauritia flexuosa").
Aedes is a genus of mosquitoes originally found in tropical and subtropical zones, but now found on all continents except Antarctica.
 Some species have been spread by human activity. "
Aedes albopictus", a most invasive species, was recently spread to the New World, including the United States, by the used-tire trade.
 First described and named by German entomologist Johann Wilhelm Meigen in 1818, the generic name comes from the Ancient Greek ἀηδής, "aēdēs", meaning "unpleasant" or "odious".
 The type species for "Aedes" is "Aedes cinereus".
 Some species of this genus transmit serious diseases, including dengue fever, yellow fever, the Zika virus, and chikungunya.
 In Polynesia, the species "Aedes polynesiensis" is responsible for the transmission of human lymphatic filariasis.
Liriope is a genus of low, grass-like, flowering plants from East Asia and Southeast Asia.
Bambusiomyces is a fungal genus in the family Ustilaginaceae.
 It was circumscribed in 2011 to contain the smut fungus formerly known as "Ustilago shiraina", originally described by German mycologist Paul Christoph Hennings from Japan in 1900.
 The fungus was originally found growing on wild Japanese bamboo, "Bambusa veitchii", but has since been isolated from several plants belonging to tribe Bambuseae in the grass family Poaceae.
 In addition to Japan, it is also found in China and other locales in southeast Asia, and has been introduced to the United States.

Question: Which genus of plants, Arthrocereus or Liriope, is originally found in more regions?
Answer: Liriope
