The small snake is found in sandy and stony soils with some vegetation as well as areas disturbed and inhabited by humans.
A new snake species of the genus Rhynchocalamus has been discovered in Saudi Arabia and it is a stunner. While the snake has a distinctive head that appears as if dipped in black paint, the area behind the eyes is a coloration that matches that of the rest of the body. In addition, Rhynchocalamus hejazicus can appear orange, red and even a reddish brown in coloration. And a uniformly black melanistic morphotype has also been found.
It fills a niche between the Levant to the coastal regions of Yemen and Oman, according to a press release by Pensoft Publishers. The team who describe the new species is from the Centro de Investigação em Biodiversidade e Recursos Genéticos (CIBIO), Portugal, and Charles University, Czech Republic, the researchers wrote.

The small snake is found in sandy and stony soils with some vegetation as well as areas disturbed and inhabited by humans, large stony wadis in lava fields that have dense patches of vegetation, and sparsely vegetated rocky creeks with temporary pools, the researchers noted in their paper. The researchers believe that the snake is nocturnal as they were all found active at night. The researchers collected field samples in Saudi Arabia in 2017, 2021, 2022, and 2023 in Hail Province, the Prince Mohammad bin Salman Royal Reserve (PMBSRR), Tabuk Province, AlUla County (Medina Province). The researchers propose to classify Rhynchocalamus hejazicus as a species of least Concern.
The paper describing the new species, “The missing piece of the puzzle: A new and widespread species of the genus Rhynchocalamus Günther, 1864 (Squamata, Colubridae) from the Arabian Peninsula,” can be read on the Zoosystematics and Evolution website.
