Comments

Hennemann & Conle (2004: 48) have shown Stephanacridini Günther, 1953 to be related to the Malagasyan tribe Achriopterini Günther, 1953 . Two of the here newly described species indeed show striking similarity in their general appearance to certain taxa of Achrioptera Coquerel, 1861 . The eggs of Stephanacris draconius n. sp., in particular resemble those of Achrioptera fallax Coquerel, 1861 , but lack the polar structures seen in this species and typical for Achrioptera Coquerel. The eggs of A. fallax Coquerel were described and illustrated by Hennemann & Conle (2004: 15, figs. 74 & 75).

So far members of Stephanacris Redtenbacher, 1908 have only been recorded from New Guinea, but there are closely related species occurring in the Solomon Islands. A detailed revision of Stephanacris Redtenbacher by the authors is in progress (Hennemann & Conle, in progress).

The eggs of the three newly described species are the first to become known from the genus Stephanacris Redtenbacher. The ɗɗ are still unknown except for those of the typespecies S. brevipes Redtenbacher.

Distribution

New Guinea.
