luridus (Glypsus) Dallas 1851: 93–94. [ Fig. 100 ]

Original data: “ ♁”; “a. Corea. Presented by Capt. Sir Edward Belcher.” [syntype (s)]

SYNTYPE ♁: blue-margined syntype disc; red-margined type disc; “ Corea / 47 21”; “5. GLYPSUS LURIDUS ,”; “ GLYPSUS ERUBESCENS Distant Det. V. Gapud 1973”; “a”; “NHMUK 010592307”. Fourth and fifth right antennomeres, and third to fifth left antennomeres missing ( Fig. 100 ) .

Current status: Glypsus luridus Dallas, 1851 .

Notes: Walker (1867a: 132) listed one specimen. Thomas (1994: 180) stated: “I was unable to locate the type at the BM(NH).” We have found one male specimen. It is likely that Dallas described the species from this unique specimen (especially as he stated one measurement and noted: “Antennae black? (the two apical joints wanting).” [emphasis ours]) but we cannot be sure, therefore we consider it a syntype.

Glypsus luridus and G. erubescens are very similar species. The fact that Gapud determined the type of G. luridus as G. erubescens may mean that both nominal species are but one taxon. We are unaware, however, of such a synonymy having been made in the literature. G. luridus is only known from the male, whilst G. erubescens is only known from the female; this needs to be further investigated.
