NIELSON, M. W., 2013, <strong> New records of Antarctic and Sub-Antarctic sea anemones (Cnidaria, Anthozoa, Actiniaria and Corallimorpharia) from the Weddell Sea, Antarctic Peninsula, and Scotia Arc </ strong>, Zootaxa 3625 (1), pp. 1-105 : 24-25

Key to the genera of Thagriini (males)

1. Clypeus with median longitudinal carina; aedeagus nearly tubular with paired, very long, slender, lateral or ventral processes attached basally; paraphysis absent; pygofer with a single pair of long processes arising caudoventrally......................................................................... Indonesia (Irian); Papua New Guinea) Tahara Nielson

- Clypeus without median longitudinal carina; aedeagus tubular, rarely with processes, when present always basal; paraphysis present, large, situated ventrad of aedeagus, articulated basally to apex of connective; pygofer with 1–2 pairs of short to long processes arising caudodorsally............................... (Oriental; Australian; Palearctic) Thagria Melichar

Key to species of Tahara (males)

1. Aedeagus with paired basal processes arising ventrally; aedeagal shaft with 2 pairs of short projections on dorsal margin and 2 pairs of very short projections on ventral margin ( Figs. 4, 5 , Nielson 1977).................................................................................................... ( Indonesia (Irian, Papua )) quadrispiculata Nielson

- Aedeagus with paired basal processes arising laterally; aedeagal shaft without projections ( Fig. 8, 9 Nielson 1977).............................................................................. ( Papua New Guinea) bigladia Nielson
