ZooBank LSID: urn:lsid:zoobank.org:act: E8FDE896-2475-4CCA-9E24-50BB0F6D05CA Included genera : Buemarinoa Roewer, 1956 , Flavonuncia Lawrence, 1959 , Fumontana Shear, 1977 , Turonychus Derkarabetian, Prieto & Giribet , gen. nov. Type genus : Buemarinoa Roewer, 1956 . Type species : Buemarinoa patrizii Roewer, 1956 . Diagnosis Buemarinoids are diagnosed using male genitalia as for the tribe detailed in Karaman (2019) . The penis has a ventral plate modified into two independent articulated and elongated lobes, each bearing two superior and three inferior setae ( Fig. 7 B ) ( Karaman 2019 , fig. 9). As the only member of Triaenonychoidea in the Southern Hemisphere, Flavonuncia is easily differentiated from all other triaenonychids in Madagascar by a combination of its small body size, yellow integument colour, an ocularium without a spine, and 3-segmented tarsus on leg I ( Lawrence 1959 , fig. 3).
