TDWG region - Region according to the TDWG standard, not a precise distribution map.

TypesHolotype: BMNH 1973.2113 

Taxonomy: Note that Echis froenatus DUMÉRIL, BIBRON & DUMÉRIL was suppressed by Opinion 1176 (ICZN 1981).

Definition: Echis omanensis has a longer tail with higher subcaudal counts; the lower prenasal scale is often missing and the upper prenasal is frequently fused with the nasal; the subnasal is often missing or fused with the nasal. The gular scales between the chin-shield and the preventrals are round or only slightly elongate, not elongate as in Echis coloratus, andtheir number is higher. Other differences in characters of the gular area indicate a different scale structure of the ventral surface of the head. The new species is allopatric or parapatric with E. coloratus, but sympatric with Echis carinatus sochureki.
