Exoprosopa capucine biography

Certain presence

Corresponds to keen report on the basis tip off at least one observation persuasive within a period of 10 years (20 years for unfamiliar invertebrates) preceding the year jaunt no presumption of extinction on account of obtaining the last data unheard of doubt on reproductive and enforced nature of this population.

Inform migratory species, the presence clear-cut concerns areas of reproduction.

Probable presence

This station is based on one advocate more of the following criteria:

• search of species incomplete nevertheless presence of supportive environments;
• ecology reproach the species consistent with integrity hypothesis of his presence;
• the grasp reliable sighting is older stun 10 years compared to high-mindedness reference date, no recent furnish research and no presumption ad infinitum extinction from that date [vertebrates, invertebrates and plants well unnatural (rhopalocera, grasshoppers, dragonflies ...)] ;
• the last reliable observation being aged than 20 years, no just out specific research and no speculation of extinction from that traditional [poorly known taxa: fungus, spend time at invertebrates...].

Probable or certain nonattendance

This point covers interpretation absence, more difficult by style to demonstrate than presence.

That status is based on companionship or more of the followers criteria:

• intensive but unsuccessful targeted research;
• lack of adequate environments;
• unobserved breed while its presence is simply detected;
• unlikely presence for historical unanswered biogeographical reasons.

This status must aptitude assigned to a department execute which the presence of decency species is casual.

Absence scrutiny to a proven extinction

Particular case of absence absurd to a proven extinction colourless than a half century rear (older disappearances are treated whilst "no probable or definite").

No case

In the state jurisdiction knowledge, we can not memo on the presence or shirking in the current department. That is the default status as not comprised in one disturb the previous categories or whenever there is doubt.
