Remarks

Yasunaga (2000) described the genus Yamatofulvius from South Japan and argued that it is closely related to Punctifulvius . He placed both genera in the Fulviini and did not compare them with any Rhinocylapus complex representatives. We examined the types of those genera, preserved in the collection of ZISP. Our analysis showed that both of those genera belong to the Rhinocylapus complex, based on the right paramere having a rounded apical part and a small cone-shaped outgrowth subapically, in addition to a reduced metathoracic evaporative area and the presence of large paired sclerites on the posterior wall of the bursa copulatrix. However, our morphology-based and total-evidence phylogenetic analyses showed that the genus is closer to Mycetocylapus and Rhinocylapoides , rather than to Punctifulvius . Unlike Punctifulvius , in Yamatofulvius labial segment I is not subdivided, and the head and thoracic pleura are impunctate, which is also characteristic for all other genera in the Rhinocylapus complex. Yamatofulvius shares with Mycetocylapus and Rhinocylapoides the ratio of vertex to eye, which is ~2.5 times, and the oval peritreme of the metathoracic glands.
