Question: Which of the countries where Euriphene lysandra occurs is the official language Spanish? 

<P0-S0> 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. <P0-S1>  The six countries are former colonies of the Portuguese Empire. <P0-S2>  From 1778 until independence, Equatorial Guinea was also a colony of the Spanish Empire. <P0-S3>  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" ). <P0-S4>  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. <P0-S5>  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. <SEP> <P1-S0>  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). <P1-S1> Euriphene lysandra, the Lysandra nymph, is a butterfly in the Nymphalidae family. <P1-S2>  The habitat consists of forests. <SEP> <P2-S0> 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 . <P2-S1>  Equatorial Guinea is the only sovereign African state in which Spanish is an official language. <P2-S2>  Formerly the colony of Spanish Guinea, its post-independence name evokes its location near both the Equator and the Gulf of Guinea. <P2-S3>  s of 2015 , the country had an estimated population of 1,222,245. <SEP> <P3-S0> 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. <P3-S1>  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. <P3-S2>  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. <P3-S3>  Some statistics claim that there are over 30 million Portuguese speakers in the continent. <P3-S4>  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). <P3-S5>  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).
