Fig. 22  
 Mortoniella pectinella is similar to the group of species discussed under M. carinula, and also to M. florica and M. propinqua, n. sp., resembling them in having a phallicata with upright dorsolateral processes and in lacking a prominent apicomesal projection on the inferior appendage. The short, apically rounded inferior appendage distinguishes M. pectinella from the M. carinula group of species and the structure of the paramere appendages, with a row of apical spines is diagnostic for the species   
Adult. Length of forewing: male 3.7 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Overall color (in alcohol) medium brown. Ventral process of abdominal segment VI (male) short, ventrally oriented, subtriangular, subacute apically, not constricted basally.  
Male genitalia. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin forming 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 broad, apically obtuse mesal projection, extending from lateral lobes, lateral lobes relatively elongate, sclerotized and acute apically, mesally curved. Inferior appendage without apicomesal projection; basolaterally, with margin nearly straight, without distinctly projecting process on each side; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages elongate, narrow, nearly uniform in width, emerging from membranous lateral projections, slightly widened basally, apical third of each appendage with spaced series of short spines on ventral margin. Dorsal phallic spine with distinct bulge ventrally, dorsal margin weakly sinuous in lateral view, apex not strongly inflected; as viewed dorsally, with apex acute, spine prominently widened near middle. Phallicata relatively short, tubular, dorsolaterally with prominent, paired, subquadrate processes, elevated basally and projecting laterally; phallicata laterally with broadly rounded, explanate, dorsoventrally flattened projections. Endophallic membrane moderately elongate, sclerotized basodorsally, with single prominent, strongly curved spine.  
 Holotype male: PANAMA: Chiriquí: Fortuna Dam Site nr. Hornitos, 1050 m, 8°55'N, 82°16'W, 8– 14.xi.1978, H. Wolda, (UMSP0001188658) (alcohol) (NMNH).   
 Etymology. This species is named M. pectinella, as a diminutive of the Latin word pecten, meaning a comb, and referring to the somewhat comb-like arrangement of spines at the apex of the paramere appendage of this species.
