Species typica

Coluber naja Linnaeus, 1758

Naja est genus anguium venenosorum familiae Elapidarum. Species huius generis late per mundum veterem extenduntur et agnoscuntur. Fiunt species in regiones per Africam, Asiam Meridio-Occidentalem, Asiam Meridianam, et Asiam Meridio-Orientalem. Angues quos tirones insigniter cum Najis confundunt sunt Hemachatus haemachatus et Ophiophagus hannah, proprie generum monotypicorum Hemachati^[1] et Ophiophagi.^[2]^[3] Typus generis est Naja naja.

Generi Najae a viginti ad viginti duae species descriptae olim erant, sed genus nuper identidem emendatum est, ut fontes academici magnopere variant.^[4] Emendatio autem anni 2009, latissime accepta,^[5] docet genera Boulengerinam et Paranajam eadem ac Naja esse. Secundum illam emendationem, generi Najae nunc sunt 38 species.^[6]

Descriptio

Species Najae longitudine variant, et corpora plurimarum sunt tenuia. Plurimae usque ad 1.84 metra longae crescunt; longitudines autem maximae sunt 3.1 fere metra, Naja melanoleuca fortasse longissima.^[7] Omnes species anteriorem corporis quartam supra solum tollere, collumque complanare ad maiores videndas possunt.
