| Distribution | Brazil (Para, Maranhao, Ceará) Type locality: “Brazil” |
| Reproduction | oviparous |
| Types | Holotype: MCZ 4660 |
| Diagnosis | DIAGNOSIS: Praemaxillary teeth, 1; maxillaries 4-4 ; mandibulars 6-6. Snout rather prominent, smooth; rostral small; a large nasal on each side of rostral meeting behind that shield on the midcephalic line; a pair of large praefrontals separating the pair of frontals from the nasals; the contour scales extend to these shields, except for several slightly enlarged scales which might be considered occipitals. It is not impossible that some would consider the scutes here called frontals, as really parietals. Eye invisible in a medium-sized ocular; this is bounded anteriorly by the first labial (which extends upward to the praefrontal), inferiorly by the third labial, and posteriorly by the upper of the two first temporals. These two temporals are followed by three smaller ones. There are but three supralabials. The infralabials are also three, the second largest. A large median chin shield is in contact with the first and second lower labials; also a pair of large chin shields are in contact with the second and third lower labials and are separated from each other by five other shields posterior to the large median chin shield mentioned above. One hundred and ninety-one annuli on body; three complete caudal annuli anterior to the ring-groove, and ten posterior to it. An annulus about the middle of the body contains sixteen dorsal and twenty ventral segments, the ventral segments being much larger than the dorsal. The pectoral shields consist of about sixteen scutes, four rows of four scales each, the two median rows largest. All the scales somewhat irregular in shape and position and a few partially fused together. Preanal scales, two large in median position, flanked on each side by three smaller scales. (Barbour 1914).

| Comment | Type species: Aulura anomala is the type species of the genus Aulura BARBOUR 1914. Distribution: Gans 1971 erroneously cited Vanzolini (1948) as having restricted the type locality to Aurá, Município de Belém, Pará, Brazil (which he didn’t). |
| Etymology | Named after Latin anomala, irregular, anomalous, deviating from the general rule. (BARBOUR 1914, Esteban Lavilla, pers. comm., April 2024) |
