N2 - Cylapinae is a mainly tropical subfamily, one of the smallest in the plant bug family Miridae. It currently comprises five tribes: Bothriomirini, Cylapini, Fulviini, Rhinomirini and Vanniini, with its representatives mostly living in cryptic habitatssuch as litter and under the bark of trees. Over the last decade numerous works on this taxon appeared; however many species remain undescribed and biological data are lacking for most of the taxa. Molecular-based phylogenyof only one tribe Rhinomirini has been published (Namyatova and Cassis, 2019); in that work the Rhinocylapus complex and Rhinomiriella were transferred to Fulviini, and Rhinomirini were limited to the Rhinomiris complex. Thatphylogeny was based on molecular and morphological data, and included the molecular data for representatives of all Cylapinae tribes. The Rhinocylapus complex includes eight genera and 24 species, and the phylogeny publishedby Namyatova and Cassis (2019) demonstrated the monophyly of this group. Punctifulvius was shown to be a sister group to the remaining taxa within the Rhinocylapus complex. However, that study included the moleculardata (COI, 16S rRNA, 18S rRNA, and 28S rRNA) for only four representatives from this clade and the relationships between other genera within the Rhinocylapus complex remained unknown. Therefore, the main aim of our study was to resolve the relationships within this group based on more molecular and morphological data. For the present study, we expanded the morphological matrix and obtained molecular data on the same four markers for six morespecimens of the Rhinocylapus complex. The topologies were constructed using methods of parsimony, maximum likelihood, and Bayesian inference based on morphological only, molecular only and total-evidence datasets. As a result, we confirmed the main results of the previous study and refined the diagnosis of the Rhinocylapus complex. We also demonstrated that Rhinocylapus, Tatupa and Proamblia are more closely related to each other, rather than to Mycetocylapus. We also confirmed that the previously described genus Tatupa Tyts et al. represents a separate genus. However, the position of other genera, Yamatofulvius, Rhinocylapoides, Rhinocylapidius as well as monophylyof Rhinocylapus remain questionable.
