 Diagnostic characters. Ablabesmyia commata sp. n. differs from other species by the combination of the following characters: antepronotal lobe with 15–19 setae, femora with 3 bands, middle and hind tibiae with 4 bands, tapered megaseta, grooved aedeagal blade, dorsal lobe club-shaped with fringe.   
 Etymology. From Latin, comma, meaning comma, referring to the shape of the aedeagal blade.

 Coloration (Figs 8A–F, 9A): wings, thorax and abdomen follow figures 8A, 8B and 8F respectively. Legs: P I, P II P III —femora with 3 bands, tibiae with 4 bands. Ratio of bands, related tibiae and tarsomeres 1 follow table 8. Hypopygium: gonocoxite apex and gonostylus base brown.

 Thorax (Fig.8B): antepronotals 15–19; humerals 11–15; prealars 23–34; supraalar 1; scutelars 31–46.
