Abstract

Victoria is emerging as the region where members of the Ordovician graptolite subfamily Kinnegraptinae, revised herein, reached its highest diversity, with 16 or 17 species present, grouped in the four genera Paradelograptus Erdtmann et al. (1987), Lignigraptus n. gen., Wuninograptus Ni, 1981 and Psenograptus n. gen. The biostratigraphic range of the subfamily extends over much of the Early and Middle Ordovician, from the late Tremadocian Aorograptus victoriae Biozone to the late Darriwilian Archiclimacograptus riddellensis Biozone. Species described are Paradelograptus antiquus (T.S. Hall, 1899a), P. pritchardi (T.S. Hall, 1899a), P. bulmani (Thomas, 1973), P. maletzi n. sp., P. orthae n. sp., P. cayleyi n. sp., Lignigraptus chapmani (Keble & Harris, 1934), L. sedecimus (Harris & Thomas, 1938a), L. ramulosus (Harris & Thomas, 1938a), L. erdtmanni (Rickards & Chapman, 1991), L. gnomus n. sp., L. absidatus n. sp., L. daangean n. sp., L. diabolus n. sp., Wuninograptus quadribrachiatus Ni, 1981, Psenograptus costermansin. sp., Psenograptus sp. A and Psenograptus sp. B. The term glossa is proposed for the elongate apparatuses that adorn thecal apertures of Kinnegraptus, Lignigraptus and Wuninograptus.

澳大利亚维多利亚奥陶系笔石亚科Kinnegraptinae

维多利亚州正在成为奥陶纪笔石亚科（本文修订）成员多样性最高的地区，共有16或17个物种，分为Paradlograptus Erdtmann等人（1987）、Lignigraptus n.gen.、WuninograptusNi，1981和Psenograptus n.gen.四个属。该亚科的生物地层范围延伸至早奥陶世和中奥陶世的大部分地区，从Tremadocian晚期的奥氏生物带到Darriwilian晚期的Archicomacograptus riddellensis生物带。描述的物种有Paradlograptus antiquus（T.S.Hall，1899a。，L.daangean n.sp.，L.diabolus n.sp.、Wuninograptus quadribrachiatus Ni，1981，Psenogractus costermansin。sp.、Psenograptus sp.A和Psenogractus sp.B。术语glossa被提议用于装饰Kinnegraptus、Lignigraptus和Wuninograptus的鞘孔的细长器具。
