One of several genera formerly contained within the type Leptotyphlops, this group contains species found more primarily in central and northern Africa into the Arabian Peninsula and even into southwestern Asia as far as India. Many are barely studied and described often only on the type specimens, but also include some taxa that currently range across multiple continents (though future genetic analyses may result in new species or genus splits). Species in this group are often grouped by pigmented dorsal scales and a notably overarching upper jaw, and usually have a reduced spine-tipped tail compared to what is typical of Leptotyphlops.
