T y p e s p e c i m e n s. Lectotype Scaphodius pictipennis FAUVEL 1907 (male, IRSNB): / Coll. R. I. Sc. N. B. (underlined), Nouvelle Calédonie, ex coll. Fauvel [printed], rec savés (ink) [red], Nouméa (white historic label glued on red label) / Coll. et det. A. Fauvel Scaphodius pictipennis Fvl R.I.Sc.N.B. 17.479 [white] / (my label) Lectotypus Scaphodius pictipennis Fauvel, 1907 , des. Matthias Schöller [red]/.

A lectotype was designated here in order to ensure the name’s proper and consistent application.

Paralectotype (male, IRSNB): same labeling as lectotype, with my label / Paralectotypus Scaphodius pictipennis Fauvel, 1907 , des. Matthias Schöller [red]/.

N o t e: This species was already known to Suffrian, who gave it an in litteris name, written on a label pinned with a specimen in ZMHB that should not be published to avoid confusion.
