Genus Lepidonella Yosii, 1960

Diagnosis. Pigmentation variable, at least eyespots dark. Scales present, apically rounded or truncate, present on head, trunk and ventral face of furcula. Dorsal chaetotaxy complete or almost complete, with few macrochaetae and several microchaetae. Antennae shorter than body. Ant. IV not annulated or subdivided, with or (usually) without apical bulb. Ant. I shorter than head length. 8+8 eyes. Unguiculus truncate or lanceolate. Abd. II to IV bothriotricha formula as 2+2/3+3/2+2. Metafemoral organ absent. Manubrium without spines; dens with one or two rows of spines, mucro variable in length, with 3–5 teeth (adapted from Deharveng & Bedos 1995, Soto- Adames & Bellini 2015).

Remarks on Brazilian fauna. Lepidonella zeppelinii Soto-Adames & Bellini, 2015 is the sole species of the genus recorded from Brazil and South America. Although L. zeppelinii fits the diagnosis provided by Deharveng & Bedos (1995) to Lepidonella and presents features which place it in Bromachantini (e.g., eye pattern), the overall chaetotaxy of L. zeppelinii is similar to Trogolaphysa spp., which suggests proximity to the late genus (as discussed in Soto-Adames 2015). The species also should be investigated from a phylogenetic perspective to make sure it is proximally related to Lepidonella spp. from the Paleotropical Kingdom or even to L. marimuti Soto-Adames & Bellini, 2015 . Additions and corrections to the original description are: presence of a discrete shallow subapical organite on Ant. IV; labial basomedian field with three or two medial ciliate chaetae (original description showed only three), and legs devoid of scales.
