|Types||Lectotype: NHR Lin-90 (formerly MAFR), designated by Wallach et al. 2014: 470.|
Type: BMNH 19220.127.116.11 (and probably additional specimens).
|Comment||Venomous! This is one of four common venomous snakes of medical importance in India. The others are Echis carinatus, Bungarus caeruleus, and Daboia russeli.|
Subspecies: All Asiatic Naja used to be regarded as subspecies of Naja naja.
Type species: Naja lutescens LAURENTI 1768 is the type species of the genus Naja LAURENTI 1768 as well as the type species of the subgenus Naja LAURENTI 1768.
Diagnosis (subgenus Naja): Extracranial (ventral) anterior Vidian canal position, 0–1 solid maxillary teeth in all species (Wüster, 1990—only 6 out of 650 specimens examined in that study had 2 solid maxillary teeth), seven supralabials with penultimate (sixth) shield low, combination of single preocular and two (occasionally three) anterior temporals, rostral broader than deep; internasals shorter than prefrontals; fang structure variable, all species except N. naja and N. oxiana have some degree of adaptation to spitting (Wüster & Thorpe, 1992b). We tentatively include the extinct †Naja (Naja) romani (Hofstetter, 1939) in this subgenus based on the shared derived condition of the basisphenoid morphology and the vestibular window, despite the possession of two solid maxillary teeth (Szyndlar & Rage, 1990).
DIAGNOSIS (species): The Indian spectacled cobra is sympatric with two other cobra species: the Centra1 Asian cobra, Naja oxiana, occurs sympatrica1ly in the northern half of Pakistan and probably extreme northern India, and the monocellate cobra, N. kaouthia, occurs sympatrically in northern India (from Delhi eastward). The characters that allow N. naja to be distinguished from N. oxiana in the zone of sympatry are shown in Table 3 (in WÜSTER 1998), and those used to discriminate between N. naja and N. kaouthia are Iisted in his Table 4. The distinction between Naja naja and N. oxiana has often proved problematic, many
authors assigning all specimens without a hood mark to N. oxiana. In particular, it should be noted that the black cobras found in parts of north-western India, Pakistan, south-western Nepal and some other areas are not N. oxiana, which
is norrnally some shade of brown, but, to my knowledge, never black Distinguishing Naja kaouthia and N. sagittifera from N. naja is usually straightforward due to the difference in hood mark shape and throat pattern, and, in the case of the latter, geographic distribution.
