As discussed previously, Mortoniella panamensis   is most similar to M. meralda (Mosely)   and M. simla (Flint)   , all of which have an inferior appendage with an elongate, asymmetrically developed apicomesal projection with a scabrous apex. Among these, M. simla   is easily distinguished by the presence of dorsolateral processes on the phallicata. Both M. panamensis   and M. meralda   have a simple phallicata, without dorsolateral processes and both lack an endophallic spine, although they do have paired phallotremal spines. Mortoniella panamensis   can be distinguished from M. meralda   by its much shorter paramere appendages and by its more sinuous and apically inflated apicomesal projection of the inferior appendage.

Adult. Length of forewing: male 2.5 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Overall color medium brown, palps lightly darker, apices of tibiae, tarsal and basal antennal segments whitish, pale brown. Wing bar at anastamosis not evident. Ventral process of abdominal segment VI missing from specimen.

Male genitalia. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin forming slightly rounded projection in dorsal half, narrowing ventrally; segment deeply mesally excised dorsally and ventrally, dorsal excision narrow, much less than half width of segment. Tergum X with short, acute mesal projection and relatively short, projecting lateral lobes, lateral lobes with apices narrowed, subacute, mesally curved. Inferior appendage with distinctly asymmetrically developed apicomesal projection, apicomesal projection very elongate, narrow, very sinuously curved at base and near apical third, apex somewhat inflated and scabrous; appendage basolaterally, with short, rounded projection on each side; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages relatively short, narrow, uniform in width, slightly curved apically, apices acute. Dorsal phallic spine sinuous in lateral view, apex distinctly upturned; as viewed dorsally, with apex very narrowly acuminate. Phallicata relatively straight, tubular, slightly constricted basally, with evident minute microsetae basoventrally, dorsally without projections. Endophallic membrane without ventral spine.
