N o t e. A neotype is designated here in order to ensure the name’s proper and consistent application, the taxonomic state of Cryptocephalus striaticollis had to be clarified as similar species were discovered which are described below. S. striaticollis can be distinguished from other species of Scaphodius with the help of the determination key given below. The neotype of C. striaticollis is in accordance with the original description given by MONTROUZIER 1861. Moreover, it is in accordance with the understanding of A. FAUVEL of this species. FAUVEL (1907) saw a type specimen of MONTROUZIER and compared it with specimens in his collection. It was a light brown coloured specimen, no such potential type specimen is present in the collection in Brussels, Belgium (IRSNB). The original description of C. striaticollis was based on an unknown number of specimens located in the collection of MONTROUZIER. The collection of MONTROUZIER was once in Paris. I was looking for these types in Paris but was not able to find them. Pierre JOLIVET, who studied the biography of MONTROUZIER, didn’t find the types of MONTROUZIER, too ( JOLIVET 2005), and assumed the types of C. striaticollis are lost (JOLIVET in litt.). The holotype was from Lifou, so the neotype is from the geographic area of the lost holotype.

L e c t o t y p e Scaphodius comptus CHAPUIS 1874 (this designation): male, ZMHB: / N. Caled. [white] (ink) / 39. [white] (ink) / Coll L. W. Schaufuss/ N. Caled. [white] / comptus Suffr. Nov- Caledonia [white] (ink) / (my label) Lectotype Scaphodius comptus Chapuis, 1874, des. Matthias Schöller [red]/.

N o t e. A lectotype is designated here in order to ensure the name’s proper and consistent application. This is one of the specimens that Suffrian communicated to Chapuis for study and that was returned later on to Suffrian. In the lectotype, the right antenna, the right fore tarsus, and the left mid- and hind tibiae are missing. O t h e r s p e c i m e n s s t u d i e d: 13, ZMHB: N.
