Calostigma Shannon, 1927: 8  , as a genus. Type species: Calostigma elnora Shannon, 1927  (original designation).

Callostigma Curran, 1930b: 8  . Misspelling.

Callistigma Hull, 1944a: 41  . Misspelling.

Ocyptamus elnora  species group, in part. Thompson (1981).

Ocyptamus  ( Calostigma  ). Mengual et al. (2012).

Ocyptamus elnora  species group. Miranda et al. (2016). 

Diagnosis. Shiny scutum with three narrow microtrichose vittae. Vein M1 straight, perpendicular to vein R4+5. Extensively bare wings. Narrow, linear alula. Oval abdomen with pale vittae.

Comments. This taxon is readily distinguished by the shiny scutum with distinct vittae, the straight M1 vein, and the distinct pairs of parallel vittae on the abdomen. Morphologically, it seems to be more closely related to Hybobathus  , but this remains to be tested. This is a more restricted view of the group than the so-called O. elnora  group by Thompson (1981), since the group of ‘…flies that have yellow scutella…’ are actually part of the O. lepidus  group ( Miranda et al. 2016).
