Description.

Of the species in the genus with broad, spatulate inferior appendages (all species except Notidobiella amazoniana ), the type species is the most distinctive based on the parallel-sided inferior appendages with their prominent, mesally directed, mesal processes.

Adult. Forewing length 7.8-8.0 mm male (n=2); 8.8-9.0 mm female (n=2). Color light brown, palps and legs stramineous; forewings light brown, with scattered golden setae. Sternum VII of male with broad, fingernail-like, posteromesal process.

Male genitalia (Fig. 4). Segment IX with anterior margin broadly produced midlaterally; tergum IX narrow; sternum IX with pair of very short, posteromesal processes, bearing long apical setae. Tergum X simple, subquadrate in lateral view, with slight apicolateral elevation, with slight dorsomesal excavation, setose apically. Preanal appendage short, ovate, setose. Inferior appendage prominent, heavily setose, spatulate, dorsal and ventral edges parallel, narrow basally, with prominent, elongate mesal process on mesal margin; strongly directed mesally in ventral view; apex exposed in lateral view. Phallic apparatus simple, tubular, slightly curved from base to apex; endophalic membranes prominent, but simple; phallotremal sclerite not apparent.

Female genitalia (Fig. 5). Tergum VIII quadrate; pleural membranes extensive, highly folded; sternum VIII broad, anterior margin with apodemal ridge, extending dorsolaterally; posterolateral corners rounded, heavily setose, especially posteriorly. Tergum IX with heavily setose, posterolateral lobes, rounded in lateral view, triangular in dorsal view; with lateral, microsetose, elevated ridge; sternum IX highly membranous, the membranes with parallel pleats or folds; tergum IX semimembranous dorsally. Tergum X with short setose projection. Internal vaginal sclerites complex (no discernable differences among the species); bursa copulatix subspherical, semisclerotized; pair of small, oval sclerites lying in membranes above vaginal sclerites (position variable).
