Roell, Talita, Lemaître, Valérie A., Webb, Michael D. & Campos, Luiz A., 2023, An annotated and illustrated Type Catalogue of the predacious Shieldbugs (Hemiptera: Heteroptera: Pentatomidae: Asopinae) in the Collection of the Natural History Museum, London, Zootaxa 5232 (1), pp. 1-105 : 76

rutilus (Oplomus) Dallas 1851: 83–84. [ Fig. 174 ]

Original data: “ ♀ ”; “a. Columbia. From M. Goudot’s Collection. ” [syntype (s)]

LECTOTYPE ♀ (designated by Distant 1880: 31): purple-margined lectotype disc; red-margined type disc; “Columbia / 46 20”; “Magd. Avril”; “12. OPLOMUS RUTILUS ,”; “a”; “NHMUK 010592399”. Second to fifth right and left antennomeres, and legs missing; right hemelytron broken ( Fig. 174 ).

Current status: Oplomus festivus Dallas, 1851 (Synonymised to Oplomus marginalis (Westwood, 1837) by Thomas 1992: 60 but see Rider & Rolston 1995: 845).

Notes: From Dallas’s original description, we do not know whether Dallas had one or more specimens, only the sex: female. Walker (1867a: 121) listed only one specimen with the same data and we have found only one specimen in the collection but cannot be sure it was the only one Dallas had (although it is likely he had just this one). Distant (1880: 31) stated: “Differs from the type by its larger size [...].” [emphasis ours]. We accept Distant’s mention of “the type” as a valid lectotype designation before 2000 ( ICZN 1999: Art. 74.5); his marking the specimen by a red-margined “Type” disc as he arranged the 63 Pentatomidae drawers in 1899–1900 ( Hampson 1906: 627) confirms which specimen was meant. Thomas (1992: 60–61) also examined and detailed “the type”. Thomas misread one of the labels as “Mayo-Abril”, it actually reads “Magd. Avril”. “Magd.” refers to the Colombian Department of Magdalena, while “Avril” is the French for “April”. “M. Goudot” can only refer to Justin Goudot, the French naturalist who collected in Colombia between 1822 and 1842 and died there around 1850 (see Lasègue 1845: 471–472 and Palmer 1918: 240–241).
