|Diagnosis||Definition (genus). Snout rounded. Basipterygoid processes, partes posteriores choanarum and supratemporals present. Quadrate expanded proximally. Meckel's groove open. Dentition (number of premaxillary, maxillary, mandibular teeth) 7; 3-4; 7-8. One unpaired shield adjacent to the rostral (modified after Vanzolini 1951).|
Diagnosis (mariae). The new species Blanus mariae is similar in external color and patterns to Blanus cinereus, but shows some different morphological characteristics and present genealogical concordance of the mitochondrial and nuclear DNA haplotypes. B. mariae is larger than its sister species; average SVL of adults 175 mm, with heads larger; average 7.4 mm and has more body annuli; average 116.6, but B. mariae has fewer dorsal and ventral segments (between 13-17 and 13-18 respectively) than B. cinereus. Color in live goes from pale pink to dark brilliant purple, with a reticulate pattern due to the intersegmental sutures. All plates of the body have the same dark purple color. Some head scales, specifically the prefrontal plate appeared slightly clearer, showing a pale pink. Coloration in preservative is reticulate mottling of brown and with the lateral sulci and the background of light beige. Usually the snout of some specimens in preservation is light beige. Genetically, both species are clearly different. The phylogenetic tree shows two well differentiate clades, forming reciprocally monophyletic units with high support of bootstrap and posterior probabilities values. The sequence divergence between B. cinereus and B. mariae in the mitochondrial gene ND4 is very high, from 10.5 to 12.4% The populations of the new species have five unique and different mitochondrial haplotypes from mitochondrial genes (GenBank accession number EF036215-EF036466, data not shown) and one unique diagnostic haplotype from the AUNL. No heterozygotes were found when AUNL was analyzed, suggesting no gene flow between B. cinereus and B. mariae. B. mariae differs from other congeneric in molecular features; from B. tingitanus in one single polymorphism and from B. mettetali in two nucleotides in AUNL data (Fig. 4). At morphological level, B. mettetali has between 8 and 10 cloacal pores, are clearly smaller (around 145 mm), with heads shorter (around 5.6 mm), with more body annuli (128.8 as average) and more number of ventral segments (between 17.8-17.5 as average) than B. mariae. B. tingitanus have the same number of precloacal pores than B. mariae (6), but is also smaller (between 152-157 mm as mean value) and with heads shorter (around 6 mm), B. tingitanus also have more body annuli than B. mariae ( between 124 and 125 as average).
Note: the diagnosis of B. mariae is quite vague and CERÍACO & BAUER 2018 synonymized it with B. cinereus.
|Comment||The publication year of HEMPRICH’s description is sometimes given as 1829. However, BAUER (2001) concluded that 1820 is the correct date.|

Type species: Amphisbaena cinerea is the type species of the genus Blanus WAGLER 1830. Blanus is the type genus of the family Blanidae KEARNEY 2003.
Synonymy: Petition for suppression of the name Amphisbaena reticulata submitted by Gans, 1961b: 223. Nomen oblitum fide International Code of Zoological Nomenclature, 1961: art. 23b, and Gans 1984.
|Etymology||Named after its color, Latin “cinis, cineris” = ash.|
B. mariae was named in honor of Maria Rosario Tortajada Aguilar E.M.A.´s grandmother, who died in tragic accident years ago, for her constant support.
