Brunia (Brunikatha) Volynkin & Černý, 2025, subgen. n.

Subgenus Brunikatha subgen. n. https://zoobank.org/ urn:lsid:zoobank.org:act: D8014194-8574-4C3E-B7F4-0F805A4E01B7 Type species: Katha montana Bucsek, 2012, by present designation. Diagnosis. Species of Brunia (Brunikatha) subgen. n. (Figs 5–21) are externally similar to Bucsekatha gen. n. (Figs 22–35) and Sany (Figs 36–38), and differ from the nominate subgenus of Brunia (Figs 1– 4) in the blackish-brown head and thorax in males. In the male genitalia, the new subgenus (Figs 56– 65) is distinguished from Brunia s. str. (Figs 54, 55) by two features. (1) The processus momenti is reduced, which makes the conjuga very short and consisting of the tendon and the thin sclerotised plate connecting the tendon and the processus momenti in the nominate subgenus. (2) The phallus condition: in Brunia s. str., its distal section has longitudinal wrinkles making it expandable whereas it is evenly sclerotised and lacks the apical wrinkles in Brunia (Brunikatha) subgen. n. The female genitalia of the two subgenera (Figs 89–97) display no fundamental differences. Etymology. The subgenus name is an aggregate of the genus-group names Brunia and Katha. Note. Species of the subgenus are herein subdivided into two species-groups clearly different in their morphology of the genitalia of both sexes.
