ClassificationFigitidae keysCynipoidea keys


Differs from all other species of Stentorceps in the circular shape of the dorsal terminus of its

corniculum (ovoid or oblong in other species). The large size and strong flare of the corniculum further distinguishes it from S. vuvuzela, S. zuparkoi and S. weedlei, whose dorsal termini sometimes appear roughly circular, but have small cornicula Nielsen & Buffington: Redescription of Stentorceps with a description of five new species 603 with weak to no flaring (S. zuparkoi and S. vuvuzela also possess thinner pyriform protuberances).


Named in honour of E.A. Abbott, the author of Flatland: A Romance of Many Dimensions (Abbott 1884). This story is about a two-dimensional world populated by geometric figures, with

circles as rulers. The distinctive flat, circular dorsal terminus of the corniculum of S. abbotti resembles one of the leaders of Flatland.
