The subfamily is taxonomically diverse, with species distinguished primarily by detailed morphological features of male , including the structure of inferior appendages and phallic . In Brazil, 15 species have been documented, most of which are to the Amazon rainforest and Atlantic Forest . Recent taxonomic work has expanded knowledge of the subfamily in South America through the description of new species and documentation of new distribution records.

Identification
-level identification relies heavily on examination of male genitalic . Diagnostic features include the shape and curvature of inferior appendages, the degree of division and asymmetry of the phallic , the presence and form of IX , and the structure of membranous projections on appendages. For example, Flintiella angrisanoae has long, slightly sinuous inferior appendages and a phallic apex divided into two asymmetrical lobes with a mesally protruding ; Flintiella quiteriae has a deeply divided phallic apex with both lobes curved rightward and the left lobe overlapping the right; Orinocotrichia has truncated segment IX processes and inferior appendages with anteroposterior membranous projections that narrow apically.
Distribution
Brazil: Amazon rainforest and Atlantic Forest (most to these regions). New distribution records established for seven species: Bredinia espinosa, Flintiella andreae, F. astilla, F. boraceia, F. triaena, F. manauara, and F. pizotensis. Global distribution encompasses 479 species worldwide.
