Crypturgus japonicus Eggers. Publication details not located ( Wood & Bright, 1992). Nomen nudum: Schedl 1979.

Diagnosis. Length 1.1–1.5 mm, mature colour brown to black. Surface of pronotum reticulate, subshining, with fine but distinct and densely set punctures. Striae of elytra deeply impressed, interstriae elevated, rugose, without reticulation or shagrination, shiny. Female declivity with a short tuft of yellow hair-like setae (sometimes abraded in older specimens) and with a pair of small patches with micro-sensillae in the middle of the tuft. COI barcodes deposited in GenBank under accessions EU 011803 - EU 011806 .

Remarks. The type material of C. cinereus was previously not located and assumed lost ( Wood & Bright, 1992; Pfeffer, 1995). However, C. Holzschuh discovered the original syntype series by Herbst in the Humboldt University collection in 1996. We have examined the six syntypes from which Holzschuh designated a female lectotype and five paralectotypes (3 males, 2 females) and concur with his designation. However, Holzschuh (pers. comm.) never published his designation of the lectotype and is therefore not a valid designation. We therefore designate the female specimen labelled as lectotypus by Holzschuh as the lectotype of C. cinereus .

The type specimen of B. minutus Duftschmid is the only one that has not been located in this or any previous work on this genus. However, there is no indication from the original description that this taxon is anything else than a typical C. cinereus specimen. The type specimens of C. corsicus Eggers in USNM and NHMW differ slightly and specimens in the USNM collection are intermediate between C. cinereus and C. subcribrosus . However, without further genetic data, it seems prudent to keep this taxon as a synonym of C. cinereus .
