Introduction

Remarks (from Syme & Poore, 2008; see reference link; references in square brackets can be found there): The genus was rediagnosed in detail by Skogsberg [9] (as Asterope) and Poulsen [19] (as Asteropina). Poulsen’s diagnosis defined the adult female s-seta as having a filament configuration of 1+6, which is true in all known species. Cylindroleberis mariae has a configuration of 0+9, and the A-1 male with 1+6. Historically, the presence or absence of a proximal filament on the s-seta has been considered a good generic character. However, within the family, the proximal filament varies continuously from absent to short to long, and the pattern has been interpreted differently. A “long” proximal filament can alternatively be interpreted as a “short” terminal filament. For example, species in the genus Bathyleberis Kornicker, 1975 [1], all with 7 filaments in total, show the full range of this character, with some described as 1+6 and some as 0+7. Further, the ontogeny of this character is not clear: juvenile females may lack the proximal filament where adults have it (Cylindroleberis vibex A-2 instar), and the reverse (Synasterope calix A-2 instar) [20]. Thus, the generic diagnosis of Cylindroleberis is expanded to include s-seta arrangements of either 1+6 or 0+7–9 filaments, i.e., between 7–9 filaments in total. There are 14 species in the genus.
