| Diagnosis | Diagnosis: Assigned to the genus Dasypeltis on account of its slender form, possession of (usually 3–4) rows of reduced, oblique, keeled and serrated lateral scales (little or no serration in D. inornata) and head barely distinct from the neck (moderately distinct in D. fasciata). Distinguished from other congeners by its unique dorsal colour pattern in which black rectangular saddles and lateral bars form complete closure around the pale inter-saddle areas (Figs 27A & 29A; this pattern also occurs on parts of the back of a few D. abyssina from Eritrea, see pattern‘5I’ of Gans 1959, Pl. VI, Fig. 4); together with a combination of the following characters: Pattern cycles 62–79 (≤62 in D. crucifera sp. nov., D. taylori sp. nov. and D.bazi; D. inornatus always uniform brown above; D. gansi uniform or weakly marked); flanks decorated with dark vertical bars (spots, blotches or squarish in D. bazi, D. loveridgei comb. nov., and some populations of D. scabra—e.g. Fig. 5G); and venter immaculate apart from a few dark markings at the edges (extensive dark markings in D. abyssina and many D. scabra); High numbers of ventrals: 236–244 in males (higher than D. scabra 180–226, D. taylori sp. nov. 196–216, D. confusa 199–227, D. atra 199–232, D. sahelensis 207–221, D. inornata 208–225, D. bazi 213–229, D. parascabra 210–223 and D. crucifera sp. nov. 226), 239–254 in females (higher than D. taylori sp. nov. 208–222, D. sahelensis 212–237, D. bazi 215–234, D. inornata 219-237, D. parascabra 224–237); Subcaudals 63–65 in males (higher than D. loveridgei comb. nov. 47–58, D. bazi 59–61, D. crucifera sp. nov. 61; lower than D. inornata 81–92, D. fasciata 59, 71–91, D. medici 69–109, D. gansi 68–83, D. palmarum 68–77, D. parascabra 67–74, D. latericia 66–86), 53–61 in females (higher than D. loveridgei comb. nov. 39–50, D. taylori sp. nov. 44–52, D. crucifera sp. nov. 49–52; lower than D. inornata 69–84, D. fasciata 64–84, D. palmarum 62–77; mostly lower than D. medici 61–90); Inter-prefrontal sulcus usually moderately, occasionally deeply, marked (usually weakly marked in other species, but weakly to moderately marked in D. bazi, usually moderately marked in D. taylori sp. nov., and variable in D. scabra [often well marked in the south of its range]); Frontal shield marginally pitted, usually State 1 (extensively pitted, States 3 & 4, in D. medici, D. taylori sp. nov. and many populations of D. scabra especially in the south of its range); Nasal divided below the nostril (undivided in D. sahelensis and D. parascabra); Postoculars 2 on either side of head (often one, especially in western populations, of D. atra); Supralabials 7 (3rd and 4th enter orbit) on either side of head (usually 6[2,3] in D. loveridgei comb. nov.).

| Comment | Habitat. This species occurs in the south-western highlands of Saudi Arabia and Yemen from 1300 m to 2300 m (annual rainfall exceeds 300 mm). Mimicry. Dasypeltis arabica sp. nov. may mimic Echis coloratus Günther (see photographs from the Sinai Peninsula in Dobiey & Vogel [2007]). Gasperetti (1988) showed that E. coloratus also occurred from Saudia Arabia to the south coast of Yemen, and illus- trated a topotype from Jabel Grayyah in Saudia Arabia (his Fig. 123) showing pale vertebral spots (described as ‘pinkish’ in the description of the holotype by Gün- ther [1878]). The new species is also similar to Echis megalocephalus (BATES & BROADLEY 2018: Fig. 30). Distribution: For a map see Sindaco et al. 2013, Bates & Broadley 2018: 12. There are apparently no live photos of this species. |
| Etymology | The name of the new species refers to the region of origin (Arabia) of the type series. |
