marginata (Tynacantha) Dallas 1851: 107. [ Fig. 103 ]

Original data: “ ♀ ”. “a. Venezuela. From Mr. Dyson’s Collection. ” [syntype (s)]

LECTOTYPE ♀ (designated by Thomas 1992: 122): purple-margined lectotype disc; red-margined type disc; “ Venezuela / 47 1”; “1. TYNACANTHA MARGINATA ,”; “a”; “NHMUK 010592371”. Second to fifth right antennomeres, fourth and fifth left antennomeres, and right posterior leg missing ( Fig. 103 ).

Current status: Tynacantha marginata Dallas, 1851 .

Note: Thomas (1992: 122) explained: “I examined the type of Tynacantha marginata , a female, located in the British Museum (Natural History). It is labeled: (a) “Type,” (b) “61 Venezuela,” (c) “a,” (d) “ Tynacantha marginata .” From Dallas’s original description, we do not know whether Dallas had one or more specimens, only the sex: female. Walker (1867a: 147) listed one specimen and we have found only one specimen in the collection but cannot be sure it was the only one Dallas had. By giving its labels data (albeit somewhat erroneously) and calling the specimen “the type”, Thomas designated it as the lectotype by inference of “the type” ( ICZN 1999: Art. 74.6).
