Mortoniella teutona belongs to a species group of closely related species, including M. albolineata , M. dolonis , and M. latispina . All of these species have the character combination of inferior appendages with a distinct, asymmetrical mesal process, dorsal phallic spine with a depressed, apically rounded, spatulate apex, and endophallic membrane with membranous lobes. It is most similar to M. latispina ; in both species the ventral endophallic spine is relatively short and curved and both species have the paramere appendages slightly widened preapically. The ventral endophallic spine is much more prominent in the other 2 species and both of these species have the paramere appendages uniform in width throughout their length. Mortoniella teutona differs from M. latispina in several details, the most diagnostic of which is a dorsal phallic spine that is either not at all, or only slightly widened in the middle, as viewed dorsally. The major point of flexion of this spine is more basal than in M. latispina . Other differences include a mesal excavation of tergum X that appears more V-shaped than U-shaped, and differences in the structure of the membranous lobes of the endophallic membrane. In M. teutona the dorsal lobes, which parallel the dorsal phallic spine, are relatively elongate and the apicolateral lobe is more or less divided into 2 sublobes which are not at all sclerotized. However, this is evident only in specimens in which this structure is expanded.

Adult. Length of forewing: male 2.6–3.8 mm, female 3.3–4.8 mm. Forewing with forks I, II, and III present, hind wing with fork II only. Spur formula 0:4:4. Overall color medium brown. Legs brown, apices of tarsi whitish, tibial spurs somewhat darker than legs, but not strongly contrasting in color. Antennae with apical part of basal segments whitish. Wing bar at anastamosis indistinct, marked with whitish setae on anal margin.

Male genitalia. Ventral process of segment VI laterally compressed, ventrally projecting, short, wide basally, rounded apically. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin convexly rounded dorsally, narrowing ventrally; segment deeply excised dorsomesally and ventromesally, forming lateral lobes, lobes separated dorsomesally by much less than 1/2 width of segment. Tergum X with broad, V-shaped mesal excision and weakly projecting lateral lobes; lateral lobes subtriangular, broad basally, apices subacute as viewed both dorsally and laterally. Inferior appendages with prominent and somewhat asymmetrically developed ventromesal projection; laterally, on each side, with setose, tapering, dorsally-directed lobes. Mesal pockets of fused inferior appendages with apical processes short, dorsally curved. Paramere appendages elongate, narrow, slightly widened in apical 1/3rd, apices acute. Dorsal phallic spine, as viewed laterally, more or less uniform in width, gradually upturned in apical 1/2, apex narrowed and acute; in dorsal view, slightly widened in middle, apex rounded, spatulate (depressed). Phallicata with sclerotized, anteriorly directed process, subtending dorsal phallic spine, and moderately elongate, narrow, projecting lateral processes. Endophallic membrane with membranous dorsal lobe, subtending dorsal phallic spine, membranous, divided or subcontiguous lateral lobes on either side, and sclerotized ventromesal spine; ventral spine relatively short, curved, apex acute; phallotremal spines absent
