Paragymnopleurus singularis (Waterhouse) ( Fig. 11 )

Neither Janssens (1940: 69) nor Balthasar (1963: 222) saw this species and only quoted the original description, the former leaving it in Gymnopleurus and the latter assigning it tentatively to Paragymnopleurus . Balthasar regarded it as a local form of P. sinuatus , the only other species of Paragymnopleurus known from the Korean peninsula. We have examined the three BMNH syntypes of G. singularis from “ Corea ”, which F. Génier (Ottawa) in 2002 re-identified as P. maurus and from which he selected a male lectotype. Since Génier’s designation has not been published, it is here validated. The lectotype here designated lacks the right metatarsus and bears seven labels, Génier’s 2002 “ Lectotype Gymnopleurus singularis Waterhouse ” (handwritten) and “= Paragymnopleurus maurus (Sharp) ” (handwritten), older “Gymnopl. singularis (Type) Waterh.” (handwritten), a male symbol (printed), and three discs – “ Corea ” (handwritten), “Type” (printed, with red rim), and “ Lectotype ” (printed, with blue rim). The paralectotypes are both females and are labeled similarly to the lectotype, but the “ Paralectotype ” discs have greenish rims.
