For this paper I analyzed the descriptions of all seventy seven currently known Macrobiotus species with three macroplacoids, with or without a microplacoid, to ascertain if they fit to the morphological diagnosis of the genus Paramacrobiotus Guidetti et al., 2009. Most (sixty three species) differed from the genus Paramacrobiotus characters as they were either members of the Macrobiotus harmsworthi and furciger species groups or did not possess the combination of two unique genus characters (elongated macroplacoids and microplacoid considerably distant from the third macroplacoid, if present). Insufficient descriptions for a further ten species means their taxonomic positions remain unclear. Four Macrobiotus species are transferred to the genus Paramacrobiotus and their new taxonomic position is Paramacrobiotus danielisae (Pilato, Binda & Lisi, 2006) comb. nov., Paramacrobiotus hapukuensis (Pilato, Binda & Lisi, 2006) comb. nov., Paramacrobiotus priviterae (Binda, Pilato, Moncada & Napolitano, 2001) comb. nov. and Paramacrobiotus sklodowskae (Michalczyk, Kaczmarek & Weglarska, 2006) comb. nov.

The genus Paramacrobiotus was erected in 2009 from the genus Macrobiotus, and 43 Paramacrobiotus species have been described to date. Although the first genome sequence in the genus was reported for the TYO strain of Paramacrobiotus sp., which is a dioecious species and has five bivalent chromosomes, its precise taxonomic identification remained undetermined.

The genus was separated from the genus in 2016 and the name referred to its phylogenetic position among the family Macrobiotidae; however, knowledge of the reproductive behavior of this genus is limited compared to those of and . This study comprehensively provides the reproductive traits, including the gamete morphologies and behavioral observations, of . The morphology of its spermatozoon showed a length that was intermediary among those of and species.

Naturally occurring fluorescence has been observed in multiple species ranging from bacteria to birds. In macroscopic animals such as birds, fluorescence provides a visual communication signal. However, the functional significance of this phenomenon is unknown in most cases.
