Plathanocera lineata Pic, 1933

( Figs 9–10 )

Pic 1933: 23.

Plathanocera lineata Pic, 1933 , Lectotype (designated here): Lastourville, Gabon, G. Lebesky ( MNHN).

Comment on the type specimens: As Pic (1933: 23) made no reference to type specimens in his descriptions of Plathanocera lineata , it cannot be assumed that the nominal species-group name, Plathanocera lineata , was based on a single specimen. The 'type' specimen located in the Museum National d’Histoire Naturelle in Paris ( MNHN) must therefore considered a syntype ( ICZN 1999: Article 73.2) and available for lectotype designation ( ICZN 1999: Article 74.1).
