ornatus (Stiretrus) Dallas 1851: 80–81. [ Fig. 142 ]

Original data: “ ♀ ”. “a. MeXico.” [syntype (s)]

LECTOTYPE ♀ (designated by Distant 1880: 28): purple-margined lectotype disc; red-margined type disc; “ Mexico / 48 11”; “6. STIRETRUS ORNATUS ,”; “a”; “NHMUK 010592386”. Fourth and fifth right and left antennomeres, and legs (except the right anterior one) missing ( Fig. 142 ).

Current status: Stiretrus anchorago ( Fabricius, 1775) (First synonymised by Stål 1870: 25 to S. (Oncogaster) personatus GERM. ; then synonymised by Distant 1880: 28 to Stiretrus anchorago (Fabricius) ; see Schouteden 1907: 9; yet, Thomas 1992: 109–110 listed a new synonymy.).

Note: From Dallas’s original description, it is impossible to know how many specimens he had, but we know that they were female. Walker (1867a: 115) listed one specimen from Mexico, adding a precision: it came from Mr Argent’s collection. We have found one female specimen matching these details. It is likely that Dallas just had this unique specimen when he described the species, but we cannot be sure. This, notwithstanding Distant’s (1880: 28) statement, which highlighted the fact that “the type” was the “only representative [of that species] in the British Museum”. We, however, 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.
