Hi !

How much was its wingspan ? I found only a measurement of its next living ancestor. This was 47 mm. I dont know what that should mean, the wingspan or the length of its boby ?

Eurytides iphitas is known from old specimens from SE Brazil in coastal mountains, but has not been seen since early in this century. May represent a spring form of E. dolicaon deicoon (which it resembles only smaller and yellower,) but it is generally regarded as extinct.

Did the female look similar to the male? Or was it different?

This species is endemic to southeastern and east-central Brazil (Collins and Morris 1985, Tyler et al. 1994), where it is known to occur at medium elevations (D'Abrera 1981). However, recent occurrence data are absent and many authors already considered this species to be possibly extinct (New and Collins 1991, Tyler et al. 1994). Historically, this species was known to occur in the Brazilian states of Rio de Janeiro and Espírito Santo (D'Abrera 1981, Collins and Morris 1985, Tyler et al. 1994). Tyler et al. (1994) state the last sighting to have been in 1937. Soares et al. (2011) report a museum specimen from Boca de Mato in Três Picos State Park, Rio de Janeiro, from elevations between 200 and 450 m asl. This species is expected to occur in the region of Santa Teresa based on habitat availability, but has not yet been recorded there (Brown and Freitas 2000). Further research is needed to confirm whether this species is still present in Rio de Janeiro (Cachoeiras de Macacu) and Espírito Santo (Alegre); however, at present, assuming known localities still hold individuals, the estimated extent of occurrence is at most around 2,500 km², based on localities in Rio de Janeiro (Três Picos State Park; Cachoeiras de Macacu) and Espirito Santo (Alegre). The area of occupancy is likely less than 500 km², and even smaller if the species no longer exists at currently known localities.

Eurytides iphitas has been assessed as Endangered. This species has undergone severe declines in mature individuals over past years, with no recent occurrences of the species reported. If it still occurs at historic localities, it would have a restricted extent of occurrence of no more than around 2,500 km²; on the whole it is known from fewer than five locations at which there is still a possibility that the species may persist. It has been noted to be possibly extinct by some authors in the past. Continued urbanisation may cause continued decline in habitat extent and quality suggesting the species - if still found to be extant - continues to be at threat. More studies are required to establish if the species persists and to evaluate optimal conservation actions to preserve this species. Evidence that the species has disappeared from known localities may warrant the threat level to be lifted to Critically Endangered or even Extinct.
