Stenogrammitis Labiak, Brittonia 63(1): 141. 2011.

Differing from Lellingeria by linear leaves less than 5 mm wide, clathrate, iridescent, glabrous rhizome scales often with a single apical hair, unbranched veins, one per segment, fertile veins usually with dark sclerenchymatous tissue visible beneath the sori, and x = 33 ( S. hartii (Jenman) Labiak ), or perhaps x = 32 ( S. limula (Christ) Labiak ; see Labiak 2011). The genus is pantropical, but most species (14) are neotropical; there is also a concentration of species (11) in Africa, São Tomé, and Madagascar; one is endemic to Ascension Island, and two occur in Polynesia and Hawaii. In the Neotropics, species occur from southern Mexico and the Greater Antilles to Bolivia and southern Brazil; there is only a single species of Stenogrammitis known from Bolivia.

Stenogrammitis is closely related, and sister, to Lellingeria ( Labiak et al. 2010 a, Labiak 2011, 2013).
