Question: Which of the countries where Euriphene lysandra occurs is the official language Spanish? 
Context: Amarakaeri is an indigenous American language of the Harakmbet language family spoken in Peru along the Madre de Dios and Colorado Rivers.  There is less than 1% literacy compared to 5 to 15% literacy in second language Spanish.  There is one dialect called Kisambaeri.  It is an official language and has a dictionary.  Amarakaeri speakers include the Kochimberi, Küpondirideri, Wíntaperi, Wakitaneri, and Kareneri gold panning tribes.  There is a common misconception is that Amarakaeri is an Arawakan language.  Alternate names include Amarakaire, Amaracaire, and Mashco; the latter of which is considered a pejorative term. Portuguese is spoken in a number of African countries and is the official language in six African states: Angola, Mozambique, Guinea-Bissau, Cape Verde, São Tomé and Príncipe and Equatorial Guinea.  There are Portuguese-speaking communities in most countries of Southern Africa, a mixture of Portuguese settlers and Angolans and Mozambicans who left their countries during the civil wars.  A rough estimate has it that there are about 14 million people who use Portuguese as their sole mother tongue across Africa, but depending on the criteria applied, the number might be considerably higher, since many Africans speak Portuguese as a second language, in countries like Angola and Mozambique, where Portuguese is an official language, but also in countries like South Africa and Senegal, thanks to migrants coming from Portuguese speaking countries.  Some statistics claim that there are over 30 million Portuguese speakers in the continent.  Like French and English, Portuguese has become a post-colonial language in Africa and one of the working languages of the African Union (AU) and the Southern African Development Community (SADC).  Portuguese co-exists in Guinea-Bissau, Cape Verde, and São Tomé and Principe with Portuguese-based creoles (Upper Guinea and Gulf of Guinea Creoles), and in Angola, Mozambique, and Guinea-Bissau with autochthonous African languages (mainly Niger–Congo family languages). Danish language is the official language in Denmark.  On the Faroe Islands Faroese language is the official language while both Faroese and Danish must be taught in schools.  Danish should be used in court, but Faroese can be used in all other official places.  Greenlandic language is the official language on Greenland and Greenland's Home Rule Act of 2009 does not require Danish to be taught or the use of Danish for official purposes.  In accordance with Denmark's official monolingualism all official documents and communications are in Danish. Latvian State Language Centre (VVC; Latvian: "Valsts valodas centrs" ) is a direct administration institution subordinated to the Minister of Justice of the Republic of Latvia.  The purpose of the State Language Centre is to implement the national policy on the use of the official language.  The Centre supervises and controls the conformity with laws and regulations on the use of official language, provides the State administration institutions and the public with official translations of laws and regulations and other documents issued by the State or international organisations while concurrently ensuring use of consistent terminology.  The State Language Centre protects rights and interests of the official language users, promotes the regularisation of the cultural environment of language and promotes comprehensive functioning of Latvian language. Bihari is the western group of Eastern Indo-Aryan languages, spoken in Bihar, Uttar Pradesh and neighboring states in India.  Angika, Awadhi, Bajjika, Bhojpuri, Magahi, and Maithili are spoken in Nepal as well.  The Angika, Awadhi, Bajjika, Bhojpuri, Magahi and Maithili speaking population form more than 21% of Nepalese population.  Despite the large number of speakers of these languages, they have not been constitutionally recognised in India, except Maithili, which gained constitutional status via the 92nd amendment to the Constitution of India, of 2003 (gaining assent in 2004).  Even in Bihar, Hindi is the language used for educational and official matters.  These languages were legally absorbed under the overarching label Hindi in the 1961 Census.  Such state and national politics are creating conditions for language endangerments.  After independence Hindi was given the sole official status through the Bihar Official Language Act, 1950.  Hindi was displaced as the sole official language of Bihar in 1981, when Urdu was accorded the status of the second official language.  In this struggle between Hindi and Urdu, the claims of widely-spoken native languages of the region—namely, Angika, Maithili, Bhojpuri, and Magahi—were ignored. The Portuguese-speaking African countries (also referred to as Lusophone Africa) consist of six African countries in which the Portuguese language is an official language: Angola, Cape Verde, Guinea-Bissau, Mozambique, São Tomé and Príncipe and, since 2011, Equatorial Guinea.  The six countries are former colonies of the Portuguese Empire.  From 1778 until independence, Equatorial Guinea was also a colony of the Spanish Empire.  In 1992, the five Lusophone African countries formed an interstate organisation called PALOP, a colloquial acronym that translates to African Countries of Portuguese Official Language (Portuguese: "Países Africanos de Língua Oficial Portuguesa" ).  The PALOP countries have signed official agreements with Portugal, the European Union and the United Nations, and they work together to promote the development of culture and education and the preservation of the Portuguese language.  Together with Portugal and Brazil in 1996, the Portuguese-speaking African countries established the Community of Portuguese Language Countries (Portuguese: "Comunidade dos Países de Língua Portuguesa" , abbreviated to CPLP), which East Timor later joined in 2002 and Equatorial Guinea in 2014. Equatorial Guinea (Spanish: "Guinea Ecuatorial" , French: "Guinée équatoriale" , Portuguese: "Guiné Equatorial" ), officially the Republic of Equatorial Guinea (Spanish: "República de Guinea Ecuatorial" , French: "République de Guinée équatoriale" , Portuguese: "República da Guiné Equatorial" ), is a country located in Central Africa, with an area of 28000 km2 .  Formerly the colony of Spanish Guinea, its post-independence name evokes its location near both the Equator and the Gulf of Guinea.  Equatorial Guinea is the only sovereign African state in which Spanish is an official language.  s of 2015 , the country had an estimated population of 1,222,245. Euriphene lysandra, the Lysandra nymph, is a butterfly in the Nymphalidae family.  It is found in southern Nigeria, Cameroon, Equatorial Guinea, Gabon, the Republic of the Congo and the Democratic Republic of the Congo (Moyen-Congo and Mayumbe).  The habitat consists of forests. Candoshi-Shapra (also known as Candoshi, Candoxi, Kandoshi, and Murato) is an indigenous American language isolate, spoken by several thousand people in western South America along the Chapuli, Huitoyacu, Pastaza, and Morona river valleys.  There are two dialects, Chapara (also spelled Shapra) and Kandoashi.  It is an official language of Peru, like other native languages in the areas in which they are spoken and are the predominant language in use.  Around 88.5 percent of the speakers are bilingual with Spanish.  The literacy rate in Candoshi-Shapra is 10 to 30 percent and 15 to 25 percent in the second language Spanish.  There is a Candoshi-Shapra dictionary, and grammar rules have been codified. English, along with Spanish, is an official language of the Government of Puerto Rico.  Spanish has been an official language in Puerto Rico since it was colonized in the 15th century.  English, on the other hand, was first introduced as an official language when the United States occupied the island during the Spanish–American War.  Since then, the Puerto Rican government has declared English an official language on several occasions while removing it from that status on as many occasions.
